DT 990 PRO

I’m by no means an audiophile, but I do care about all forms of digital consumption enough to make an investment in a good pair of headphones. I usually categorize my headphones based on needs and wants. For example, I use Sony Hear Ons as “lifestyle” headphones because of the Bluetooth capabilities and its portability. I also have the AKG K553’s as my “reference” headphones for editing. My goals for my next pair is something I could use with my desk setup for studio use as my daily headphone. After reading a plethora of head-fi posts and watching multiple YouTube reviews, my search led to the Beyerdynamic DT990 pros and to this day I can’t get enough of them. At first glance, you wouldn’t expect it to be a premium headphone due to the fact that it’s made almost entirely out of plastic except for the headband and the arms connecting it to the ear cups. The headband is wrapped with a soft layer of fake leather, which can attach and detach with a few clasp buttons. Don’t let the nearly plastic design fool you because it’s pretty high-quality polymer plastic and the build itself is solid. In most cases, it’s actually a good thing because it makes for a lighter headphone, perfect for long uses. The adjustments aren’t as smooth as an all-metal design, but it works fine and can extend to fit almost any head. The cable is coiled and runs around 3 meters ending in a gold-plated 3.5 mm jack. It also comes with a screw on 1/4 inch adapter, which is also gold-plated. Beyerdynamic is known for their velour ear pads and they’re probably the best part aside from the sound. It has a plush and smooth feeling unlike any other. The clamping force is somewhat tight, but I got used to it pretty fast. Some people might be concerned about the whole velour vs pleather thing and based on the performance and comfort I wouldn’t worry about that. Just to clarify, velour is known to be more open with less isolation compared to pleather. It’s also known to be harder to keep clean (can get dusty) simply due to the nature of the material itself. In terms of sound, I actually prefer the more open soundstage, which makes sense since it’s already an open-backed design. If you’re worried about cleanliness just make sure you wipe it often and try not to use it if you’re super sweaty from the gym or anything like that. Judgement on looks is subjective, but the comfort is out of the question. Given the light-weight form factor and velour pads, I found the DT 990 pros to be cloud-like even after hours of usage. Now for the good part, the sound quality. As previously stated, I’m no audiophile, but I have to say that these headphones are no joke. I’m pretty basic so I listen to most mainstream music (EDM, Hip-Hop, Chillstep, etc.) on Spotify, I watch plenty of YouTube, and I also watch a bunch of TV shows and movies on Netflix on my MacBook Pro. I also use these when I game on my PS4 Pro. With these factors for reference, I found these headphones to be my best audio investment yet. The bass is definitely prominent especially for an open back design without being too overpowering. It’s actually the biggest factor as to why I decided on buying these because I was looking for an open back headphone with good bass, which led me to the DT 990’s in the first place because they’re known to be great with both features. Between the Pros and the Premiums, a bit of research led me to conclude that the Pros had slightly more bass, which I prefer. The mids have a lot of detail but don’t shine as much. The highs are incredibly clear but can get a bit too bright for my taste. Sometimes it’ll result in a slight ear piercing sensation depending on what I’m listening too, but your mileage may vary. The soundstage is wide and gives a great representation of spatial cues resulting in an accurate listening experience. The 250 Ohm model is the sweet spot out of the three, but make sure you have a good amp to power them. Personally, I use the Behringer AMP800 Four Channel Headphone Amp and it works great. I tried connecting it to my iPhone for comparison and it’s still listenable, but you’ll have to max out the volume. I’ve had my DT 990’s for over two years now and it definitely stands the test of time. Unless you have a bunch of money to spend on something like a pair of Sennheiser HD800’s, there’s really no need to look any further when presented with great value. The price is just right even for the average consumer and offers professional grade quality. Having crystal clear audio isn’t hard to get, but when making an investment it’s important to read the fine print and research all the opinions. With the DT 990’s I can truly enjoy all digital content and I’m confident that you will too.

I will post what I posted on Head-Fi. Before I get to the review I should add that this has not been burned in yet so this is an impression of the initial sound. I should also add I listen to mostly pop, but also bass heavy music as well as other genres. The term audiophile basshead would best fit me and my sound signature taste. Equipment: - FiiO E12 amplifier - Behringer UCA222 DAC - ViPER4Windows audio software Comfort: You'll have to try them on to really appreciate their comfort. The revviews say there is a heavy clamping force but I beg to differ...it's quite low and enough to the point where it stays on your head and is hardly noticeable. The earpads are very soft and have a ridonkulous amount of cushion to them, they're like pillows and they engulf my ears which is nice. 11/10, far more comfortable than my electrowaves with DT770EVB earpads. Sound: Bass - Not as strong as open cans, and not nearly as strong as all of the reviews claim...but still strong for open cans. These do have bass, don't get me wrong...but not basshead pleasing without EQing and adjusting other bass related settings. Once everything is adjusted properly, it can provide some nice bass, but it still lacks a bit in quantity. The quality is quite good though, although like one review I came across said, it does sacrifice quantity for quality. It was a bit difficult finding the right settings, but I will definitely post a picture of those below for insight. I also did find the right driver to rattle, it is probably a hair, but it has not gone away yet...will have to figure out how to fix that. 9/10 Mids - I am not too concerned about the mids, and haven't had cans that are good with mids...so I cannot say much here. I will say, and take this with a grain of salt considering my situation, that the vocals of songs were stunning. I haven't heard vocals like that from anything and am very impressed. Some said that the mids were a bit recessed...I would agree if the bass is set high enough, it can definitely overpower the mids if that is the case. I would disagree when it comes to the vocals though, they were right up front regardless of the bass. 9/10 Highs - The supposed killing factor for most...I say that's pure bollocks. I am treble sensitive, I don't like piercing notes as they give me a headache. When I first put these on, I did so with an amp and that's it. I can see why people say it can be a bit much, but it's nothing to be concerned about. I did get a little bit of fatigue from the treble, but people are over exaggerating. I found the treble to ever so slightly sibilant, but nothing major. 8.5/10 Leak - These are open cans, expect them to let in sound, and let out sound. I can hear my TV quite well, with these on as I type. While it is a tiny bit muffled, it's still very much audible and it's of acceptable volume. As for sound going out, these do leak more than you would expect, so be prepared for that. If you have your EQ/software settings set to a more dark sound it will not leak as much, but them mids and highs are going to be heard loud and clear. 6/10 Imaging - Not quite sure what this is, but following the definition I would say these do that quite well. Cannot say much else, but reproduction does seem to be good. I don't know if this fits here or not, but poorly recorded songs or songs with poor quality will definitely suffer in all sections. I won't rate this. Soundstage - This is what impressed me the most. I was frequently surprised at hearing an instrument or sound I never knew was there in quite a few songs. The soundstage is much wider than I expected, and throughly impressed me. 10/10 Build quality: I would tent to agree with the others on this. Everything is good...it's German made, so it not a surprise. I really don't need to add to this as others have already said what I'd say. 9/10 Design: I'll keep it short and sweet since this isn't really relevant. It's nice, but I definitely prefer the premium look. Plastic doesn't appeal to me, but it is designed well. I won't rate this. Overall I'd say this would earn an 8.5/10. It could do better in aspects, but it is quite well. If "audiophile basshead" fits you, then this will likely appeal to you, if you lean more towards a heavier basshead it likely won't. I for one am happy with it...can't wait to hear how it sounds at 100 hours. It could use a bit more bass though. I will update when the 100 hour burn in is complete. I have about 4-5 hours under the belt, but due to the rattling issue I am likely going to RMA so I will have to start over again.

Um ótimo fone pra mix e master.

Le uso ormai da più di un anno in modo praticamente ininterrotto e non ho mai avuto un solo ripensamento. Comodità top, le indossi per ore senza affaticarti, e il sound è davvero impressionante: dettagli nitidi, scena ampia, bassi presenti ma mai esagerati. Si sente che sono fatte in Germania, materiali solidi e zero scricchiolii. Per mixaggio o anche solo per ascoltare musica come si deve, per me restano una scelta sicura.

Just received these this afternoon. I already own Amirons, DT 880s and DT 770s and Grado SR80s. I’m not a fan of Sennheiser, so anyone who is familiar with both Beyerdynamic and Sennheiser headphones will appreciate that this is a subjective review by someone who likes Beyerdynamic’s house sound. This review is my assessment of them purely for home use. There are obviously loads of reviews of the 990s on the internet, and although very popular they obviously divide opinion. I shan’t make out that these are for everybody, but I’ll add my three pennies worth here which might cut through the superlative laden ayes and the damning nays and help some people to make up their minds on whether or not to buy a pair (I dithered for far too long). When I was in my early twenties I might have found the Beyerdynamic sound too bright and analytical, but back then I could hear frequencies up to 20khz; not so now, at 63 my hearing tops out just under 14khz, so maybe this accounts for my later-in-life infatuation with the Beyerdynamic sound. Though I like most forms of music, the bulk of my collection veers towards acoustic music - classical, jazz etc - there’s also a fair bit of dub reggae, rock, EDM and so on (so, it’s basically Prince Far-I to Schubert, Aphex Twin to CSNY, Thelonious Monk to Joni Mitchell, Public Enermy to Spirit, Poppy Ackroyd to Bob Dylan - catholic, essentially). I’ve only had a few hours to make comparisons (Bill Withers, Thelonious Monk, Radio 3, Bill Charlap, Heart of the Congos, Lana Del Rey), but I think this has given me adequate opportunity to make a pretty accurate judgement of the characteristics and comparative merits of the 990s. I’ve been listening to them mainly through a Little Dot Mk 2 with a combination of Novosibirsk and Mullard 8100 valves (sourcing from a Cyrus Cd and Cyrus 8 DAC amplifier). I’m delighted with the 990s. They are neither shriekingly sibilant nor either lacking or over-endowed with bass. Compared to the other headphones that I own I would say that the 990s are nearest in sound to the 880s. Indeed, I think that they are very near sound-wise. The 880s are marginally more polished, but the difference (to my ears at least) is subtle rather than dramatic. I would suggest that the 990s are very good, cheaper alternatives to the 880s. The 880s clamp the head noticeably more lightly than the 990s, but the 990s are more secure on the head. Sound leakage is similar in both, so neither are good for listening to next to your sleeping partner (who hates going off to music and especially hates jazz) in bed unless you want a poke in the ribs. For this I have the 770s, which have a somewhat “fuller” or “fatter” sound than the other two. Leakage on the 770s is minimal at low to modest volumes. The Amirons (Homes) are, to my mind, decidedly more “musical” or “liquid” sounding headphones, very enjoyable for extended listening and very revealing, in comparison with those I would describe the 990s and 880s as rather “analytical” sounding and the 770s are somewhat “dryer” (I hope describing their sound as both “dryer” and “fatter” doesn’t sound like a contradiction in terms but I can’t immediately think of a better words to describe the sound). However, they’re all good and all have what you might call a “house sound” (i.e. a Beyerdynamic sound), although the Amirons depart furthest from this sound (which isn’t really very far at all) while the others might all be considered even more typical. The Amirons have a fuller, certainly pleasant and, I would say, slightly coloured bass by comparison, the bass on the 880s and 990s is leaner and, as far as I am qualified to judge, seemingly more accurate. Some people say that they both lack bass, but I don’t think this it true, it is most certainly there when it’s there! It may be that those who think they lack bass are listening to these headphones without suitable amplification. As goes the 770s, I’d say that their bass - in terms of weight - lies in the middle here, it is perfectly good but it is neither as accurate as on the 880s and 990s nor as pleasurable as on the Amirons. Sound stage is best, and very similar, on the 990s, 880s and Amirons. I wouldn’t say that there is any vastly significant difference here between these three headphones. The 770s, being closed-back, are noticeably more “closed-in” in terms of soundstage but, in terms of closed-back headphones per se they’re actually really rather good in this area; I’ve certainly not encountered a closed-back pair that are better (or indeed any other closed-back pair that I can actually bear - I personally much prefer open-back designs, for me the 770s are exceptions in this department). The 1770s may well be better, but I’m not about to fork out several hundred pounds more for those when I use closed-back headphones mostly for listening in bed via the headphone output of a Roberts radio. As regards comparison with the Grado SR 80s, the 990s and 880s are decidedly superior sounding, with the Grados sounding rather rough and uncouth by comparison (though this isn’t helped by the Grados comfort levels which are simply not in the same league - half an hour with Grado SR80 ear pads is sheer torture; consequently I’ve replaced them with Sennheiser HD414 ear pads which improbably (as, apart from being yellow, they don’t seem materially that different from the Grado pads) improve matters a fair bit and don’t noticeably change the SR80s sound). The Grados do sound more bassy, but this is definitely a matter of quantity rather than quality. Build quality on the Grado SR80s is also markedly inferior to that of the Beyerdynamics. I would retire the Grados at this point, but their 32 Ohm impedance makes them useful. They’re good fun, but they’re not good for extended listening sessions. The 990s and 880s with their 250 Ohm impedance definitely need amplification. I use a couple of Little Dot Mk 2s. The Amirons have the same impedance but are significantly more sensitive. For unamplified use I find the 770s a better match with their 80 Ohm impedance (they certainly work well with most Roberts radios of recent years, Roberts seem to have pretty good headphone circuits on their radios). Summing up, I think that the 990s are fantastic value for money (the Amiron Homes, which I love, are perhaps a clear case of diminishing returns by comparison). If you’re thinking of buying a pair of Beyerdynamics, want open-backed headphones, fancy the 880s from all you’ve read, but feel that the 880s are a stretch for you financially, then I think you’d be missing very little with the 990s in terms of sound). Originally, I had thought of purchasing Beyerdynamic’s new DT900 X headphones, but - reading the reviews, and knowing how much I already liked the sound of the 880s and 770s - I thought I’d save myself some money and get something that might not sound so hugely different for half the price and, beyond that, I actually prefer the look of the 990s. I don’t rule out considering the new series in future, but for now I don’t feel I’m missing out on anything that would be game-changing, although I admit I’m curious. As I have found repeatedly, however wild the superlatives I encounter in the reviews the actual differences between the last and the latest model of a particular piece of hifi is more often than not a matter of nuance. Whatever way you cut it, comparing the 990s with the highly regarded and (to me) very similar sounding 880s and the more refined, more relaxed, but four or five times more expensive Amiron Homes, they are still very good sounding headphones and first class value for money - assuming, like me, you like the Beyerdynamic sound. If you’re a Sennheiser fan you’d probably be barking up the wrong tree (but you know that already) and, if you’re a Beats fan, then presumably you’re already stone deaf. And then again, as goes highly regarded budget headphones, I reckon they knock the Grado SR80s into a cocked hat. But not everyone would agree with me. Anyway, I hope all that helps. Update, 28/1/22. I’ve now spent some more time listening to the 990s on a Little Dot Mk 2 with a combination of Novosibirsk and Radio Technique valves (sourcing from a Naim CD5 via a Rega Elex R). The Radio Technique valves are very similar to the Mullard 8100s I used at the top of this piece. Continued close listening has only confirmed my sense of how good these headphones are. On further consideration, with this set up, I’d say their sound signature lies between that of the 880s and the Amirons. I’d say they sound slightly “weightier” than the 880s and that the Amirons are a bit more so, but the differences here are more subtle than seismic. On careful comparison, after a few hours of listening, my overwhelming sense at this point is that, if you like open-backed headphones, like the Beyerdynamic sound and have a hankering for a pair of Amirons but either can’t afford them or can’t justify the expense, then you really wouldn’t be missing very much at all by just settling for a pair of 990s. By comparison they are a real bargain and, I think, in absolute terms they are quite simply one of the best bargains there is on the headphone market. One further point, on comfort, although the 990s have more clamping force on the head, I actually find them more comfortable than the Amirons as they fit my head better. Finally, as anyone who has read this far has already probably figured out, it has cost me quite a lot to reach my conclusions here. I think I have a reasonable sense of humour, but if you’re an audiophile sceptic then I guess I can understand why you may feel you’re getting the last laugh! I’m glad I own the Amirons, they are very nice headphones, but if I could only have one pair I must admit that I’d very happily settle for the 990s. Postscript, 31/1/22. On further reflection, it’s very good having several headphones all sharing a general character that I like, but each a little different from the others. Different music works best on certain headphones (for instance, listening to Beatrice Rana’s performance of the Goldberg Variations this morning I much prefer the rendition of her piano’s sound through the Amirons to that of the 770s (the piano sounding decidedly more lifelike through the Amirons), whereas with Thelonious Monk’s It’s Monk’s Time the difference is less obvious and, if anything, I’d say I actually prefer the 770s with their greater attack. But, different music is not all: different recordings, different source equipment, different mood of the listener ... however, it’s very quick and easy to change between modestly priced headphones during a listening session in order to optimise your listening experience (something you can’t readily do with expensive speakers, amplifiers, cartridges and so on).

Eines vorweg, ich bin kein Audiophiler und kann daher nur meine persönliche Meinung wiedergeben. Ausserdem wollte ich ein Headset/Kopfhörer mit offener Bauweise - ist für mich angenehmer. Ich wollte ein neues Headset haben, welches ich zum Spielen, Teamspeak und gelegentlichem Musikhören nutzen kann. In diversen Foren wird davon abgeraten ein Gamingheadset zu kaufen und stattdessen auf eine Lösung von Kopfhörer und Mikro zu setzen. Ich wollte mich allerdings selber davon überzeugen und haben die erwähnten Produkte bestellt um sie selbst auszuprobieren. Meine technische Voraussetzung war ein Gaming-PC, allerdings mit einem Onboard-Soundchip (Realtek® ALC1150). Mein altes Headset ist/war ein Plantronics GameCom 788 USB Headset mit Dolby 7.1 Surround Sound mit Sourroundsound - Der erste Punkte dazu: Ja, Stereo ist besser! Beide Headset sind wesentlich besser als mein altes. Sitz: Das Sennheiser ist unglaublich bequem und kann über längere Zeit getragen werden ohne zu drücken. Das Beyerdynamic ist jedoch noch ein bisschen bequemer, was denke ich an den Velourpolster liegt. Verarbeitung: Die Verarbeitung ist allerdings beim Beyerdynamic besser, da hier u.A. Metall verwendet wird, aber auch genauso Plastik. Trotzdem sind beide Headset Qualitativ weit vorne. Was die Langlebigkeit angeht kann ich kein Urteil fällen, denke aber nicht das eines von beiden demnächst den Geist aufgibt. Beyerdynamic hat hier nur den Vorteil das Ersatzteile einzeln zu bestellen und auszutauschen sind. Mikro: Hier kann nur das Sennheiser bewertert werden. Das Mirko ist super, besser als mein altes und zählt zu den besseren, welche direkt verbaut sind. Die Verständigung ist für Teamspeack und Skype mehr als zufriedenstellend. Somit vollkommend ausreichend für durchschnittliche Ansprüche. Praktisch - Das Mikro hochklappen und es ist stumm. Wer denkt es ist ein Schwachpunkt kann recht haben, aber bei meinem Plantronics konnte das Mikro auch hochgeklappt werden und nach 3 Jahren ist kein Verschleiß zu erkennen. Wer profesionelle Aufnahmen will, sollte zu einem Rode oder ähnlichem mit Großmembran greifen. Musikqualität: Ich höre eher weniger Musik mit den beiden Produkten da ich eine Soundanlage habe und keine Nachbarn die sich daran stören. Daher war die Qualität in diesem Bereich nicht so wichtig. Aber beide Kopfhörer haben eine Super Soundqualität. Das Beyerdynamic hat bei jedem von mir getesteten Musikstück einen fantastischen Sound an den Tag gelegt. Die Höhen und Mitten sind sehr ausgeglichen und klar. Mir fehlt es jedoch an den Tiefen - könnte durch den EQ geändert werden. Ich wollte aber keine umständlichen Änderung im EQ vornehmen, sondern die Musik so hören wie sie kommt. Trotzdem gibt es hier keinen Grund über die Qualität zu meckern und wenn denn auf ganz hohem Niveau, was mir nicht zusteht da ich mich nicht gut genug auskenne. Das Sennheiser schneidet in diesem Bereich minimal schlechter ab, hat jedoch einen stärkeren Bass was ich positiv bewerte. Dafür fehlt es vielleicht etwas an den Mitten. Für reines Musikhören würde ich das Beyerdynamic empfehlen, da es ein minimal besseres Klangbild hat. Kenner würden mir hier widersprechen und das Beyerdynamic uneingeschränkt empfehlen und das Klangbild und die Bühne in den Himmel loben. Ich höre jedoch keinen so großen Unterschied raus um mich hier streiten zu können. Trotzdem gewinnt hier das Beyerdynamic, so oder so. Mann sollte jedoch überlegen, dass für das Beyerdynamic eine exteren Soundkarte ratsam wäe, da hier 250Ohm befeuert werden müssen. Die Asus Xonar U7 Externe 7.1 Soundkarte (Kopfhörerverstärker, 114dB, Dolby Home Theater v4) wäre hier meine 1. Wahl, ist mit knapp 90 € aber auch nicht billig. Selbst Gebraucht sind hier um die 60€ fällig. Sollte man vorher wissen. Interne Soundkarten sind nicht zu empfehlen da es hier zu Interferenzen kommen kann. Gaming: Der für mich wichtigste und entscheidene Punkt. Das Beyerdynamic bietet die Qualität um das Plantronics ganz hinten anzustellen. Gegner zu hören, die Umgebung wahrzunehmen und den Sound zu genießen, den der Hersteller angedacht hat, ist hiermit einfach nur ein Traum und hebt die Soundkulisse auf ein neues Level. Ich war sehr beeindruckt von den neuen Kopfhörer/Headset und enttäuscht wieviel ich mit dem alten Headset verpasst habe. Trotz oder gerade wegen Stereo ist eine Ortung dermaßen präzise wie ich es vorher nicht kannte. Alle die mir nicht glauben wollen - hört euch den Virtuel Barber Shop auf Youtube mit Stereokopfhörern an! Schritte sind sehr gut wahrzunehmen um eine Richtung auszumachen und damit spielt es sich nochmal besser. Das Sennheiser hat hier aber den entscheidenen Vorteil, da der Bass druckvoller ist. Ich persönlich bin der Meinung Gaming Headsets sind fürs Gaming ausgelegt und das merkt man hier. Es ist kein "überteuerter Scheiß mit Gaminglogo". Auf Grund der Tiefen sind die Waffengeräusche, die Schritte und Geräusche besser wahrzunehmen. Die Ortung ist ein ticken präziser. Wo ich beim Beyerdynamic höre das da jemand ist, kann ich beim Sennheiser sagen wo genau und ggf wieviele. Es ist insgesamt runder und ausgeglichener vom Hörgefühl. Ich fühle mich mit dem Sennheiser wohler beim Spielen. Die Bühne und das Klangbild sind phänomenal - bei beiden. Als Nebeneffekt hat das Sennheiser die Möglichkeit die Lautstärke am rechten Hörer zu regeln. Das alles kann aber auch nur für mich persönlich gelten, weil jeder einen anderen Anspruch hat und auch eine andere Wahrnehmung. Ich habe, bevor ich mich entschied, meine Freundin gebeten beide Produkte ebenfalls zu testen. Sie kam zu einem ähnlichen Ergebnis wie ich - Ihr gefiel das Beyerdynamic vom Komfort besser, aber vom Sound wäre es das Sennheiser geworden. Fazit Es ist sehr schwierig hier jemanden zu dem einen oder anderen Produkt zu raten, da die Unterschiede für Laien zu minimal sind. Beide Produkte sind in ihrer Preisklasse, meiner Meinung nach, mit das Beste was man kriegen kann. Ich habe mich für das Sennheiser entschieden auf Grund der Vorteile beim Spielen, da ich den Klang und die "Ortung" besser finde, aber auch wegen der Komfortfunktionen - Mikro inkl, welches zu stummschalten nur hochgeklappt werden muss und die Regelung der Lautstärke direkt am Hörer. Eine Lösung mit dem Beyerdynamic + Mikro und die Steuerung über Makro's wäre aber genauso gegangen. Es sollte jedoch beachtet werden, dass man beim Beyerdynamic über kurz oder lang nicht an einer externen Soundkarte vorbeikommt, da hier die maximale Lautstärke schwächelt. Qualitativ macht es ausserdem so ca. 20% aus. Für mich ist es auf der einen Seite das nicht wert, auf der anderen Seite hat mich das Sennheiser als Gesamtpaket für meine Ansprüche mehr überzeugt. Ich danke fürs Lesen und bin auch gerne bereit offene Fragen zu beantworten oder bei offensichtlichen Fehlern im Text diese zu korrigieren. Alles geschriebene spielt nur meine ganz persönliche Meinung wieder. Bei einer Bewertung in jedweiliger Form ist dies bitte zu berücksichtigen.

Ce casque ouvert est d'excellente qualité et très confortable. Le son est spatial, on entend bien tous les détails d'une musique (et même parfois ses imperfections, ce qui me convient parfaitement pour mon utilisation). Un casque d'une telle impédance nécessite forcément un amplificateur, sinon vous ne pourrez pas profiter au maximum de ses capacités, et surtout, le son risque d'être trop faible. Ce n'est donc pas un casque qui conviendra à une écoute sur smartphone par exemple. Les aigus bénéficient d'une surbrillance que je considère comme étant très poussée. Cela ne peut pas forcément convenir à tout le monde, et vous remarquerez que les avis à ce sujet varient d'une personne à une autre (Mais aussi de l'âge de l'utilisateur, puisque nous perdons naturellement notre sensibilité d'écoute des fréquences hautes avec le temps). Pour ma part, utilisant ce casque sur un ordinateur, je suis obligé de me servir d'un égaliseur pour réduire les aigus, sinon je ne serai pas en mesure de supporter ce casque trop longtemps. Le processus d'égalisation, réalisé à l'aide d'un logiciel en temps-réel, le rend parfait selon moi. Il faut aussi un petit temps de rodage pour s'y habituer. Le fait qu'il soit ouvert signifie aussi que votre entourage pourra entendre ce que vous écoutez, pas forcément de manière excessive, mais c'est suffisant pour empêcher une personne de dormir si elle se trouve dans la même pièce que vous. C'est le principe d'un casque ouvert. Mais en contrepartie, cela vous permet d'entendre les bruits autour de vous (si quelqu'un vous appelle à une certaine distance, etc), et c'est exactement ce que je recherchais, ne pouvant pas supporter les casques fermés qui donnent l'impression d'être enfermé dans une "bulle".
