Neoteck Portable 3.5mm Headphone Amplifier with Bluetooth 5.0 Receiver, Two-Stage Gain Switch, 16-150 Ohm HiFi Earphone Amp, Aluminum Matte Surface

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.

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

The media could not be loaded.  Marca una gran diferencia en cuanto a experiencia sonora , y por 32€ , que cualquier ampli de marcas conocidas tipo ifi o fiio suben a 110-150€ los mas baratos , es sin duda una parte imprescindible para disfrutar de un audio Hi res , si se pudiera equalizar no me importaria pagar 60-70€ , pero aun asi esta brutal.algun dia probare uno de marca buena a ver si hay tanta diferencia.El acabado es muy robusto y con buen tacto, el led de colores mientras funciona me parece super chulo. si que es un poquito grande al tacto, pero asi tambien lo encuentras mas facil sin mirar.

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.

J'ai acheté ce produit pour mon oncle qui entend mal.Connecté à son casque pour regarder la télévision, cet amplificateur augmente le son oui, mais pas tellement. En tout cas c'est à peine suffisant pour lui.Je m'attendais à mieux.
