Neoteck Portable 3.5mm Headphone Amplifier with Bluetooth 5.1 Receiver, Bass Boost Switch, 16-300 Ohm HiFi Earphone Amp, Aluminum Matte Surface

Easy to use, pairs quickly with my laptop. Sound quality is fairly good, I enjoy just listening to music with this. Bass Boost is a great feature on this model, it adds base and it is helpful for headphones that need that kind of 'sound color' adjustment. Very happy that I bought this model, rather than the one without bass boost. The headphone amp does not have any hum or any other noises. The reviewer that mentioned it, probably has area in their house/wires with bad static coming from one of the outlet. My appartment has this issue too (any wire connected to that outlet, be it a wall plug, or even a wall plug with a USB charging cable, -- they will add hum when this amp, and another one I have, Douk P10 when anywhere near those cables). But that's not the fault of the amp, it is the fault of the wiring/grounding of the power outlets. Many small hifi sound amps use high internal voltage, 20v or 30v to allow for good sound output quality -- those circuits are sensitive to bad AC noises even if the amps themeselves are not connected to an AC outlet. A lack of features such as support for a microphone, and ability to skip next/back music track switching -- make this amplifier less useful. I listen to short lectures and I would appreciate this switch on the amp, so that I do not have to walk back to my laptop every 5 minutes. But I knew the lack of these features buying this. Anyway, it would be great if the manufacture keeps the great sounding amp features, and add these usablity enhacements. And also would be great if they make the internal battery replaceable (of course, with opening the case) -- to make this a true winner and a unique product in this price range!

Genuinely punches above its weight class. Coming from a Fosi Audio desktop Class A amp and a Fosi Audio Class A tube amp, I was looking for something with a neutral sound that I could add a little bit of "fun" to with the bass. The bass response is on a shelf on the extremely low end. This allows for a higher bass response with minimal quality loss in the mids and absolutely zero difference in the highs. I tried this amp's bass boost on and also off with my Beyerdynamic DT 1770, Hifiman Ananda Nano, HD 600s, and several IEMs, and this is the first amp I've bought where the gimmick genuinely feels like a magic switch. If you are showing a pair of HiFi headphones to someone and they think it's lacking bass, this amp is perfect and for the price should at the very least be picked up to spice up your sound occasionally. This is my new daily driver for right now, and the build is excellent.

It works pretty good. The sound is very good but it doesn’t work with my over the ear headphones. In Bluetooth mode it pairs with my iPhone simultaneously with the amplifier but I get no sound, so it only works with the wire plugged in. I’m going keep it anyway. It could just be the 5.1 Bluetooth functionality with my version 17 iPhone, not really sure. Oh well they sound great though.

The Bluetooth really sucks

Installed on my goldwing to have Bluetooth capabilities, plug and play. I was advised to pair it with a ground loop isolator to eliminate fuzz, so I did, extra $6. Works good, sounds good.

Will have to return. I'm not sure how to make the mic on the ear cord functional. It's only got audio out and audio in. No separate mic input for a splitter.

It works and seems to work well, but the TV had problems, so I don't know how long it would last

This thing is quite a bit more impressive than I anticipated! I did have a wee bit of trouble with it initially FINDING my device but once it did it was firm and steady! It will reach from the living room into the bedroom without a lag! When they say heavy bass they are Not kidding! If you use it for external speakers have a care with that bass switch! LOL! I also use these to power a set of logitech z623 speakers and it does a bang up stand out job but watch that volume! Fact I like them so much I bought two more to give away at Christams! They make Great stocking stuffers! A most useful little device! Thanks for a great product! It is solidly made and well Built. None of this plastic junk! Highly recommend both product and SELLER! HAW!

Bon matériel très bon bluetooth bon Amplificateur et basse percutente

OK, Tutto come descritto.

Ich benutze ihn zum Fernsehen gucken abends über bluetooth am Magenta TV Stick der ersten Generation. Angeschlossen wird ein beyerdynamic DT 770 PRO X Limited Edition. Die Lautstärke am Stick steht auf Maximal und der Neoteck sehr leise, es ist genug Kraft vorhanden für den Kopfhörer. Selbst am Samsung galaxy s24 und Spotify kann er überzeugen. Den Bassknopf habe ich immer eingeschaltet, sonst klingt alles ein wenig dünn. Jetzt muss nur noch die Haltbarkeit überzeugen. Wer noch mehr Details im Klang haben möchte sollte mehr ausgeben, für meine Zwecke aber mehr als ausreichend.

Product ontvangen en linker kant van de koptelefoon deed het niet, bij meerdere koptelefoons. E-mail gestuurd naar support maar tot op heden geen reactie. Teruggestuurd naar amazon en een refund ontvangen. Veelbelovend apparaatje, maar niet bruikbaar zo. Op zoek naar een ander merk.

Compré este amplificador para auriculares con Bluetooth para mi padre. Él ha perdido la audición en un oído y necesita aparato en el otro. Probamos diferentes opciones. Conectar por bluetooth el audífono a la televisión no era satisfactorio y usar auriculares bluetooth, aunque su volumen funcionase de manera independiente del del televisor, muchas veces no le permitía escuchar el sonido con nivel y/o claridad suficiente, a pesar de usar distintos auriculares de diferentes marcas como JBL y Sony. Finalmente opté por probar esta opción. Al incorporar Bluetooth, este amplificador se puede conectar inalámbricamente al televisor y, a su vez, se conectan, mediante la salida jack de 3,5 mm del amplificador, unos auriculares normales. El resultado ha sido plenamente satisfactorio. El audio es nítido y con intensidad suficiente para escuchar sin problemas. El amplificador dispone de un potenciómetro que controla su volumen. Si se pone a tope si que empieza a haber una ligera distorsión, pero la realidad es que nunca se necesita superar la mitad de su recorrido para conseguir un nivel de volumen suficiente. Además también cuenta con entrada por jack de 3,5 mm por si se quiere conectar una fuente externa sin compatibilidad con Bluetooth, y un refuerzo de graves que en nuestro caso no usamos. Otro aspecto positivo es su compacto tamaño, de medidas similares a las de un móvil normal aunque más grueso. Otras opciones, con una solución similar a la que ofrece este aparato, pasaban por amplificadores de dos canales con un precio bastante más elevado y de tamaño bastante mayor, mientras que la mayoría de los parecidos a éste carecían de Bluetooth. En resumen, un aparato perfecto para lo que ofrece que en nuestro caso ha satisfecho plenamente nuestras necesidades, por un precio comedido de poco más de 30 euros, y cuyo único inconveniente que se le puede achacar es que requiere el uso de auriculares con cable, un elemento que empieza a ser raro hoy en día, pero que para nosotros no ha sido en absoluto un obstáculo dados los beneficios que ha aportado.
