FIIO FD3 PRO Earphones in-Ear Earbuds High Resolution 1DD Deep Bass Detachable MMCX Connector with 2.5/3.5/4.4mm Plugs DLC Black

Highlights: Above average soundstage. More sense of depth than height. Decent imaging/instrument separation. Good sense of details - catching some details in recordings that I hadn't caught in other sets (KZ, CCA). Decent dynamics. Good texture in the mid-bass and mid-range regions. With the right tips, fit, and insertion depth - these can achieve almost 3D/holographic effect. YMMV, but I'm enjoying these with SednaEarfit Crystals and the FD3 Pro cable. Just very musical sounding, overall. Some describe the FD3 Pro as tonally warm, but I find them to be somewhat slightly warm to neutral tone. Not nearly as neutral as my Etymotic ER3SE but not as colored/warm as my CA Honeydew. Lowlights: Treble could be better, can be slightly harsh at times, but for the price? They're still very good. They're a fun set that I can wear for a few hours at a time. They're very well-made though I wish they were a little bit lighter.

EDIT/Update: I am changing my review to 5 stars. The Spinfit CP100 silicone eartips in XL made these earphones a perfect fit for my ear and the improved seal made the sound of the earphones even better. (If you have normal-size ear canals, you'll likely be happy with one of the included sets of eartips.) I am now extremely happy with these earphones for listening to music and practicing my bass. This won't be a surprise to most audiophiles, but the silicone or foam tips for IEMs are as important as the IEMs themselves. These earphones have excellent frequency response (flat across the spectrum with good bass and highs) and great staging. My only problem is my very large ear canal - the largest silicone tips provided are barely large enough and I have to fiddle with the earphones to get a decent seal (the memory foam tips included don't work with my ears at all). The best seal I've gotten so far is with tips off of my Samsung Buds 2 Pro wireless earphones, but they're not designed for the nozzles on the FiiO set. I have ordered some Spinfit CP100 silicone eartips in XL which will be here tomorrow and should fix my issues. Again, I believe these are excellent earphones and are heads and shoulders above the Sennheiser IE 200s I tried and returned.

Well, I will fully admit that I am no audio file. However, I do like good sounding music and with my new FiiO M21. I do hear more vibrant great bass from my phone. Which does not sound bad. I must admit, although I do use it in Bluetooth mode. I’m very happy with the purchase l!

Great weight to these. Amazing sound

Sounded great but ultimately ended up returning for a few reasons. First issue for me was the fit, I tried different eartips that cane included and also purchased other but regardless couldn't get the best fit. The other issue I noticed is that since the nozzles can be removed/switched, I'd notice they would (with the slightest adjustment/movement) start unscrewing. This might just be a me issue because of the fit but I'd always have to tighten them due to them unscrewing. And the main issues I had: is that at times when connecting them to a dongle (my phone doesn't have a 3.5) they wouldn't actually connect. Like it'd say it was connected and I would press play on a song but no audio would be coming though, neither through my phone speaker or the iem but the track would be playing. Its not the dongle; I have 4 total so and I had the issue with all of them, and I tried different earbuds and they worked well with those dongles. And lastly sometimes I'd notice that the right earbud would sound as loud as the left earbud. Not sure if this had something to do with the nozzle unscrewing with the slightest movement or it'll its something else. I still have it 3 stars as I believe some of these issue might just be due to the fit for me and may not apply to others, plus the sound when everything was working fine was great.

These Fiio's well outperform my comparably-priced Shure earbuds. Good bass. Midrange is very detailed while still maintaining a presentation more natural than commonly found in earbud-type earphones.. Highs can be a bit overstated, depending on the source material, but not harshly so. Quite solidly constructed, and if either cable ever does fail, as happened with the Shure earphones, they are replaceable. This was an important consideration after having my Shure's crap out on me in that way.

Got this to compare with Fiio fh3 with Fiio LC 4.4B cable. Both are driven by a radio stream from my iPhone into a Fiio Q3. Both use the 4.4 jack for optimum resolution. The fh3 was slightly pricier at about $ 130+30(cable). It has 3 drivers and performs much like a high quality 3 way acoustic suspension speaker. It is very capable and covers the entire frequency range well. The fd3 has one driver and reminded me of BOSE 901 speakers that used a bunch of full range drivers. The sound is rich and less refined to me This can be a good thing. I feel closer to the music. Both are good. Some tracks are better with one than the other. The LC 4.4B cable that I bought to go with the fh3 is much more comfortable than the fd3 pro cable. It may be slightly superior sound wise but I would prefer to have two LC 4.4B cables.

Solid build material, hefty, feels great. But unfortunately, I can't really tell the difference between these and $20 similar iem ones (aside from volume) Don't know if it's me, but not worth the price increase.

High quality high definition ear phone from Fiio China. Well done.

Excellent casque. Pas de graves « inventés » (effet boum boum). Des aiguës de très bonne qualité, scène sonore large. Très confortable et léger (nombreux embouts fournis). Excellente finition. Assurément un produit haut de gamme à un tarif raisonnable. On regrettera juste un manuel un peu succinct.

Superb when paired with the Fiio D15 R2R CD player/transport. Have a listen to the CD by Bob James - 'Feel like Makin' Live' which has been immaculately recorded (read the sleeve notes how they did it) - Rhodes & Piano/Double Bass/Drums. - Absolutely sensational on the Fiio FD3 Pro earphones. A great product at a reasonable mid-price range. Highly recommended if you're serious about music!

Kesinlikle muhteşem bir kulaklık ses kalitesi ve ses yüksekliği bakımından olağanüstü. Sennhiser ie200 ve momentum 4 vazgeçilmezlerimdi fakat bu kulaklığı alana kadar. Ayrıca bu fiyat bandında alanibilecek malzeme kalitesi olsun kutu içeriği olsun en iyi kulaklik diyebilirim ki şöyle bir tavsiyede bulunmak istiyorum kulaklik guc istiyor kendini kapasitesi o zaman ortaya cikiyor kesinlike bir dac ihtiyac var, bu kulaklığı almayi düşünenler kesinlikle Fiio K11 kulaklik amplikatoru ile birlikte alsınlar Mi15 dac im olmasına rağmen Fiio ka11 aldim muhteşem uyumlu oldu tavsiyem birlikte alin.

As a senior citizen seeking comfort when on line without constant noise interruption this solved my many beefs. My robot vacuum and a number of blue tooth application in addition to yelling next door neighbours frustrated my listening pleasure. I have Sony earbuds but they will connect to other devices in close proximity. Having a direct connection to my laptop allows me to enjoy powerful acoustics and uninterrupted dialogue. Highly recommend this selfish pleasure.
