Yes, "Impressive". Wired & Bluetooth both excellent with enough amplification to drive Sennheiser HD 660S2[300ohm] headphones from laptop even at low gain. Sound quality seems neutral with no noticeable distortion, Good solid well finished aluminium case and nice touch that illuminated eoteck logo subdued and not distracting.If affordable, well worth the purchase.

A straightforward product that turns any wired earphones into Bluetooth headphones. Plug your headphones into the device, connect it to your Bluetooth source and you have audio. The volume control is quiet and can accommodate many types of headphones.Likewise, plugging in a wire from a music source turns the unit into a simple headphone amplifier. Surprisingly useful and decent quality.The large battery seems to last forever, but obviously will need recharging. It will certainly last through any flight.This is an excellent product for people on the go who like to listen wirelessly. It is not an ultra high-end product, nor does it boast the very latest Bluetooth protocols, and the DAC is not state of the art. But it also doesn't cost hundreds of Euros. It is a good example of sensible engineering that sounds perfectly fine. I love mine, and find it useful to keep in my jacket when I go out. The battery is ample, the controls are easy to use and the electronics are quiet and the sound is excellent. I plug in my earbuds and I'm wireless.

I waited 4 months before reviewing this, just to make sure my first impressions were accurate.I wanted something to drive a pair of Beyerdynamic DT-770 Pro 80Ω Limited Edition headphones, streaming FLAC audio from my Plex server via mobile/tablet.This little amp is powerful enough to drive 80Ω audiophile/studio grade headphones easily with good loudness at 2/3 full volume on normal gain, and without distortion at uncomfortably loud levels on high gain. There is some very faint almost indiscernible background hiss at high volume levels with music on pause/between tracks, but that seems to disappear as soon as signal is received.Output is very clean/flat/neutral, so much so that I started looking at my Samsung Galaxy tab Android built in Sound Profiles, and discovered that I have measurable hearing loss in my right ear at high frequencies. I now have an 'Adapt sound' profile set up to counteract that.I could try and sound all professional and audiophile, but simply put, this Amplifier paired with a decent set of headphones has transformed my mobile listening. I am hearing details I was never aware of before on music I have owned for years; music that I have listened to on various mid to high range amplifiers (e.g. Denon) and speakers (e.g. B&W) over the years.If I was trying hard to find something to complain about, I can say that Bluetooth range is mediocre, borderline reception at max 10 meters in absolute clear line of sight, but even so much as a dining room chair in between and it is down to 5 or so meters. Really not an issue for me since I have the amp right next to my mobile device, but might be good to know.Others have mentioned the quality of the volume control. I am treating mine with care, and have the amp in a hard case with my headphones when it's not in use.

Device is heavy build - strong metal case - and feels very solid . The amp connects very easily to my iPhone through Bluetooth and gives great power to my headphone , the sound is phenomenal , specially if you think about its price ! For some reason the headphone sounds better then before! Some headphones may need a converter plug from big toSmal connection. …A very worthy 5 star product !!!So buy this , tut will not be disappointed!

Pros:Amplification is good with no noiseCan do bluetoothBattery does last a long time nearly all dayDecent rangeCons:The gain switch does very little, but for me this isn't an issue as the max vol is far more than enoughIt can do bluetooth SBC-XQ (the higher quality higher bitrate one) but set on this is stutters every minute no matter the computer or phone its paired with or the range so I'm docking a star as ill have to use normal quality SBCBluetooth pairing takes no passcode so its very easy to pair

He400se 'yi gayet güzel besliyor. Herhangi bir sıkıntı, dip ses vs yok. Shuoer S12 taktığımda biraz dip ses alıyorum ancak bu gayet doğal çünkü iemler düşük güç tüketimi ve yüksek hassasiyetlidir. Yani gereğinden fazla güç verirseniz dip ses duymanız doğaldır. Sarjı gayet iyi ve belirtilen sürelere kadar dayanıyor. Kendim sıradan samsung sarj aletinde masada sürekli bağlı kullanıyorum, herhangi bir statik ses yok. Ancak bilgisayarın usb girişine bağladığımda statik ses epey duyuluyor. Kısacası elektriği verdiğiniz cihaz statik sesin varlığı açısından son derece önemli. Şarja bağlı değilken herhangi bir statik ses yok. Düşük güçlerde sağ sol dengeside fiyatına göre gayet tatminkar. Gücü yaklaşık %10-15 i geçtiğinde sağ sol dengeleniyor. O değerin altındayken soldan ses biraz daha az geliyor. Bu elinize gelen üründen ürüne değişiklik gösterebilir. Genel olarak fiyatına göre gayet iyi olduğunu düşünüyorum. En azından markasız dropship ürünü değil. Kendi siteleri vs var kontrol edebilirsiniz.

I rarely give 5 star reviews. This one is well deserved and was hard earned.I was looking for a device that could receive Bluetooth audio and feed it to the auxiliary input in my work truck.The other options, while functional, left the audio sounding flat, weak, and honestly underdriven. I was seriously wishing I could get away with installing an amplifier.With this, I got my amplifier on the input side without a permanent installation or anything that could get me in trouble.The result was clean, powerful, boosted sound that didn't sound like it was falling on its face.The instructions say not to use it plugged into a power source due to system electrical noise. This does happen, but with an estimated 8 hour battery life and a work day that can run 16 hours sometimes, this was not an option.Using an inline noise filter between this Amp and the stereo input really solved that problem for me.I can't believe I have only had this little guy for a year.This little device, about the size of a deck of playing cards is well built with an aluminum body instead of cheap plastic construction. As I drive a concrete mixer in some extreme circumstances sometimes, rough is a necessity. This fits the bill, and doesn't break the bank to do the job.I highly recommend it, and will buy another one again so I don't have to keep moving it around.Update to my review, after 15 months, the right channel quit working.After opening it up, I found that some of the solder joints between the volume control knob's board and the main board were broken. After heating them up and reflowing the solder, it works as good as new.Update number 2 to my review. I have had this little guy now for nearly 3 years with no further issues since fixing the broken solder joints. As of today, May 14, 2025, I have had the unit for 34 months.

Ich war auf der Suche nach einem bluetoothfähigen Kopfhörerverstärker, um einen Beyerdynamic DT770 mit 80 Ohm damit zu betreiben. Das funktioniert mit diesem Teil sehr gut. Ich nutze es beim Schlagzeugspielen zum Einspielen von Metronom oder Übungstracks. Die erreichbare Lautstärke reicht locker, der Akku hält >4h (mehr habe ich nicht getestet) und die Soundqualität passt. Rauschverhalten ist aus meiner Sicht völlig ok. Wenn ich den Verstärker voll aufdrehe, hört man natürlich ein leichtes Rauschen, aber wenn ich dann ein vernünftiges Nutzsignal anlege, fallen einem sowieso die Ohren ab...Ich kann das Teil echt empfehlen, da Preis/Leistung hier echt stimmt.Achja, Lieferung war trotz GB+Zoll usw.

Pros:SERIOUS volume boost, clean/clear balanced sound amplification that is more than loud enough & I seriously mean loud enough, probably to loud/powerful for a wide range of earphones, earbuds, headphones & IEM's, compact enough to be portable & pocket friendly, tactile volume control, can be "hardwired" as well as Bluetooth ability. Bluetooth pairing is simple, easy & stable within 20ft, almost 30ft with no obstructions, 2 stage gain switch is definitely noticeable when switched from L to H, very lightweight, easy to use. Decent battery life. Metal shell. Good build quality.Cons:This an amp without a DAC, no play/pause or track control, charges micro USB not Type-C which is a subjective con on my part, many ppl won't even care & have at least 40 spare micro USB cables these days..., might be too big,/not compact enough for some. Battery life: should be better/longer; considering the size of device. In my opinion it should have a bigger battery... should be closer to 24hrs or more not the 8hrs in the description. Bluetooth range could be better & should be considering it's big enough to accommodate a bigger/stronger Bluetooth antenna..bluetooth signal starts to breakup after 20ish feet & can also be disrupted entirely if objects are in the way of signal (ie: walls, more than 1)Would I suggest or recommend this device to others looking for a Bluetooth headset amp?Overall, Yes. Definitely.Bottom line; if all you're looking for is "more power/higher volumes" to your audio headgear.. You've found it. To that end it preforms Fantasticly...it can easily get more than loud enough to give the user an urge to want to turn it down a bit.I don't see a person needing to deal with Bluetooth signal issues all too much when considering it will most likely be worn "on person" with a wired headset via phone or mp3 player with or without Bluetooth & not used at a distance.The sound quality is balanced, full, rich & lively. It amplifies the sound given to it. That said it's up to the device the signal is originally coming from to "filter" or clean up the signal. Highs are clear, crisp, technical & articulate. Bass is super solid & not "muddy" drowning out mids or highs. Mid-range is smooth & rich. Vocals are forward/front center. Staging is more detailed & wide when being used with higher quality headphones/IEM's.The device is very lightweight & compact enough to not be noticeable on your person unless you don't have pocket(s) that can accommodate. Volume control is user friendly & simple unlike a button (that's purely subjective on my part. I prefer a knob over a button)Take note that this amp potentially has enough power to actually burn out/"fry" cheap earbuds & headphones. If you're looking for something with more features than just volume control or want to use at a distance.. this might not be for you.
