Audioengine HD4 Powered Bookshelf Speakers – Bluetooth 5.3 aptX Adaptive, 24-Bit DAC, Desktop Speakers for Music, Gaming and Home Audio - Black

I researched this type of product well before making my purchase, lots of good other reviewers for products from the same company, both more and less expensive. This is a happy medium product for me, and I am very happy with the product and its capabilities. I am a location audio recording person and audiophile, and while this product at this price point is clearly not a world beater, that is not the object of this type of product. What I can say is that this product sounds decent with live streamed audio (SiriusXM usually), and is not annoying to someone used to listening to accurate acoustic audio / recordings. The switching amp actually sounds pretty decent, and this rig is well worth the price. It is easy to move from room to room when needed, and comes with nice sleeves for the speakers so that when taking in 'on the road' the rig is reasonably well protected.....a nice touch I am not sure others have mentioned. The bluetooth range is decent, and the only thing I would say is that it does not automatically reconnect after shutting it down one evening and starting it up the next morning with my Tab 7+. I have decent sound when using the bluetooth, and therefore the built in DAC, that I have not tried to compare using the line in function. If I wanted premium sound I would use a different rig, but this is great for work out music, and or background music when doing something else. If a bluetooth rig would have been my only audio playback rig I would have opted for the larger brother of this unit, for the clarity of the bass if nothing else. Yet this unit does well by itself for non-critical listening, and I would gladly purchase it again. Happy customer, pleasantly surprised.

I’m in a relatively smaller room (approx 12’ x 16’) and have a corner setup for a mix of both work and play. I wanted to declutter some wires from my setup while pursuing a solid quality sound/bass on the desktop end of things. Hours of research led me to audio engine and more specifically their hd4’s. At first I was pretty hesitant about paying a couple of hundreds dollars on quality desktop speakers but after receiving these speakers I quickly began to understand the price tag. The sound quality on these guys are amazing from just about any angle in my room. They are both minimal in design and setup, which I am a big fan of and the wooden finish quickly grew on me. I only have one usb wire running from one of the speakers to my computer, the power cable, and the connection from active to the passive speaker — which is a great improvement. On top of that, the low latency Bluetooth works like a charm; ideal for when I am not actively on my computer (or on my work laptop) an am looking to play off a device such as my phone. The only minor downside (and this is more out of pickiness) is the omission of desktop speaker stands which can help angle your speakers slightly upwards for enchanted listening pleasure. It’s not a deal breaker since you can get them from audio engine on the side ($34 bucks last time I checked) but I feel that at least some alternative to these stands should’ve been included given the initial price. Overall, very happy with this purchase and look forward to these lastime me quite a while.

Bought these speakers to accompany a new Pro-Ject turntable and they sound fantastic. The bass levels are excellent compared to the pair of Edifiers they replaced. I can’t crank them up completely because they reside in a small NYC apartment, but I can tell you Paul’s Boutique sounds amazing. I can’t tell you anything about the Bluetooth functionality because I’ll never use it.

Seamlessly moves from bluetooth turntable to Apple Music, which is what i wanted most. Great sound! (Although can't fine-tune treble, bass). Good for our living room music listening.

Does not play all bit rates... I contacted the company and they said that 88.2 bitrate was uncommon (I have quite a few downloads in 88.2)... sorry. Further the tonal balance is just... umm odd... I compensated by installing Equalizer APO (Windows)(not that easy to configure) and got the sound to be pretty OK. Also, out of the box, it doesn't sound good, you need to break them in... takes a week or so of heavy use. This break in issue is no big deal, most speakers require this. But overall, I am bit disappointed that I had to put work into getting them to sound good and it won't play some of my files. Set up is easy.

The AudioEngine A2+ are really amazing speakers, but I just miss that bass a little, so tried the HD4. In my opinion, this HD4 speaker added bass, but at the expense of the highs and mids. Not that HD4 is extremely bass booming. It kind of muddied everything. I am going to stick with the A2+ and just add a small subwoofer. The HD4 is a great 4-inch woofer speaker, but not $180 nicer than the AudioEngine A2+.

Run these for a few hours before freaking out - they need time to chill out ;-) They are far better after a dozen hours to my ears. If your after big sound rock concerts - these are not the droids... sorry.. speakers you're looking for. Acoustic, Jazz, Mellow, Classical are best IMO. They don't lack normal bass but just don't have that big thump. Great mix of features and blue tooth is really solid. I also love that you can have wired and blue-tooth connected and BT takes priority - I use it to connect two computers and play music on one while I work then swap for conference calls. I don't have them in an ideal location (mine are too low as under monitors angled up) but they still do great. Shame this does not have a sub out like it's smaller brother - feels like a downgrade to me even though I'm not running a sub. Only down side I have the is cost - they really are steep.... but in the end that fades over time.

Gave out entirely with distorted and crackling audio after only two years of use. for the price you should opt for a more reputable brand.

Głośniki grają i wyglądają świetnie, ale ciągle piszczą, nawet gdy nie jest podłączone źródło. To wysoki i bardzo nieprzyjemny dźwięk, który je praktycznie dyskwalifikuje.

Son de qualité et puissant. Très faciles à installer.

10/10 recommend these speakers, got them on 20% sale, would 100% do again. Their bass is awesome for their size. While still outputting voices amazingly. Treat yoself and just do it *edit* After listening to them more, listening at 80-100% volume they overheat after about 30 minutes which is lame especially for the price point. Will be trying some methods to figure out how to cool because they do sound very good. Updated review to 2 stars *edit edit* Fixed the overheating, inside the speaker at the back of its amplifier it is packed with fluff/insulation material that sits right on and around the heatsink, after opening it up and moving/packing the insulation off the heatsink there has been no problems. Really enjoying these speakers, shame i had to pull it open to fix.

sehr basshaltig was insbesondere nachts ein echtes problem darstellt, weil keine bass o treblereglung vorhanden! zudem vibrieren die membranen ziemlich stark bei einer bestimmten tonlage - was jedoch nicht öft der fall ist

ちょっと削り過ぎな帯域もあるが中音域、高音域の伸びや鮮明さは良い。値段の割にDACが PCM5102 ていうのがちょっと納得いかないが、文句があるならD1買えということでしょう。ただ、DACよりももっといただけないのがmicroUSB type-microBな所。せめてUSB Type-Bにしてください。なのでオーディオ用のUSBケーブルが実質エレコムしかない。あと、低音はもう無いものと思ったほうが良い。S8必須。このスピーカーでウーファーいらないって人どんな音楽聴いてるの？と思う。S8と鳴らすと一気にポテンシャルが上がる。
