Neoteck Bluetooth 5.0 Headphones Amplifier, 16-300Ω HiFi Headphone Amp with Screen Indicator & Dual Gain, Rechargeable Portable Headphone Amplifier, 3.5mm AUX for Phone MP3 MP4

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.

Quality little Bluetooth portable amp it's quite small in size but packs a punch. I have the volume on number 8 you can't have it higher cos it starts to break up. Has for value you can't grumble. I use Dr dre beats Solo headphones and it sounds awesome. Battery performance is excellent lasts over 7 hours even on continuous high volume. Would highly recommend the volume knob is of good quality i have had no issues with it unlike some reviews have mentioned. Takes roughly 3 hours to charge

In terms of function and design - it's perfect, excellent. Bluetooth to the mobile phone, plug in headphones to the device, just one lead, job done. Good power. Better than the non-Bluetooth version as that means two leads instead of one. The volume dial (design/idea) is perfect and the device size, it's functions, the power, the volume dial - all perfect and really works for me. Not having experienced the sound quality of different (more expensive) devices, however this device, for the cost, is at least very good, I was not found to be wanting with regards to volume or sound quality. I did unfortunately have some longevity/wear and tear issues, so would recommend to treat like a brand-new, expensive mobile phone with a large screen: be very careful with it. I use this at work in a Warehouse and did have some seemingly premature longevity issues, however I'm pleased to say that the supplier/seller actually do care about their customers' satisfaction and I was pleasantly surprised when the seller reached out to me about the issues I experienced, and resolved/made better of the issues I experienced, so whilst the devices' robustness/sturdiness is good but perhaps not great, I feel this was more than made up for with the suppliers' excellent customer service, so at the very least you can be assured of good sound quality and power, and excellent customer service from the supplier. Whilst I did look around at (more expensive) alternatives, I have to say that no other amplifier actually met my needs as much as this one did (despite some costing a couple of hundred pounds), and in fact this device remains the most fitting and appropriate device for me. Shall be extra careful with this one and hope it lasts a long time! My thanks to the supplier/seller for their great communication and service.

Firstly,I have hearing damage,hearing loss and tinnitus and I was therefore very pleasantly surprised and impressed by its performance,improving the situation markedly. The bluetooth connection means that the input device can be left on charge,with no interference,but don't charge the H/P Amp at the same time. This doesn't have all the bells and whistles of the top end headphone amplifiers,but neither does it carry their price tag.Sporting 3.5mm in/out Jacks,lo/hi boost switch,vol knobs incorporating on/off switch,usb C charging port and that's it. Sound quality is quite acceptable, with crisp top end and bass lift.All in all it equates itself very well indeed.

Great device

I have tested this with a pair of grado RS2e and it drives then ok. At maximum volume there is some noise from the amplifier without signal but turning down the volume solves this. You might notice this on quieter tracks if you like it very loud. Bluetooth also adds a more noise which my Grados pick up but on less revealing headphones you probably wouldn't notice this much. It is a bit unfair plugging in headphones that cost £600 into an amplifier of this price. Sound is louder and generally better quality overall using the cable option instead of BT, but less convenient. Sadly it does not support aptx in any form. For me it is let down by an average noise floor. So I decided to return it. Audiophiles look elsewhere. I am sure they could improve the noise floor with some tweaking and component upgrades especially that screen the Bluetooth RF from the audio path.

So about one year ago I bought the neoteck kt106 to use it in my car . I was surprised about the really good quality of the sound. But unfortunately one channel stopped working so I got a replacement. The sound quality is so low you barely can hear the highs and mids.

Bought this to go with my ne Beyer DT 770 Pro's and it's a great addition. Adds a volume boost as the 32ohm headphones straight into the phone work great but the phone is mostly working at approx 85% output capacity so doesnt give much room for increase. Add this headphone amp into the mix and it completely opens up the sound. Obviously much more volume output but also adds to the overall dynamics of the sound allowing the headphones to be driven with more power and clarity. The overall output is greatly improved. Add the this the ability to connect the headphone amp to your device via Bluetooth and it makes it even more attractive. My only very minor issue it that the edges of the case are rather sharp it it would be nice if they were rounded off slightly but overall, pleased with the amp.

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.

nessuna critica .Ottimo prodotto. Qualcuno a detto di aver difficolta sul collegamento con Bluetooth, posso affermare che nel mio caso uso il ricetrasmettitore Soomfon Mod. BT17 in funzione TX ed il collegamento in area libera supera i 20 metri, all'interno dell'appartamento va benissimo su tutta l'area nonostante le pareti divisorie e le colonne in cementarmato. Pilota benissimo le mie cuffie da 60Hom, nessuna distorsione, io lo uso per l'ascolto TV con ottimo risultato; il ritardo tra immagine e audio è impercettibile,bassissima latenza. Ottimo prodotto merita più di 5stelle. Complimenti al costruttore.

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.

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. < 5 Tage.

Geluid is gewoon goed en maakt snel contact met bluetooth. Heel tevreden mee.
