Neoteck Portable 3.5mm Headphone Amplifier Two-Stage Gain Switch, 16-300 Ohm, Aluminum Matte Surface

I bought this to replace an older unit that never delivered very much amplification. Can't say that about the Neoteck unit. It has plenty of power delivering increased amplification to my earbuds, through 15 feet of cable, with a very low volume control setting. I use it to amplify the sound from the Samsung TV with the TV volume completely turned down so that I don't disturb my sleeping wife. The unit works perfectly, and the build is quality and very solid. I especially like having a rechargeable battery to save on battery purchases. With a full charge I watched a 3 hour movie and the unit then recharged in a very short period of time. The sound quality is very good with no distortion or feedback. I am very happy with this device.

Good little amp. Sound is very good. Housing is small. Easy to place it in pocket. Best thing is it is not consuming phone’s internal battery power.

Works well, just what you need to use and hear computer earphones.

This is a really useful gadget. It happens fairly often that when I'm trying to watch a YouTube video, the volume is so low that I cannot hear what's being said. This amplifier makes that problem disappear. If you experience this same problem, definitely give the Neoteck amplifier a try!

Very impressed with this product super high-quality, works very well! You turned it up too high, God help you. This is not for children.

I got this little amp about 4 months ago and I've been using it with a pair of Logitech G Pro X headphones. When I got them, they were restrained by the output of my phone or the little DAC they came with. I got this amplifier and it has really brought out the potential of these cans. One of the first things I listened to was some Hans Zimmer and the experience was incredible, with the additional volume and depth this amplifier adds. I am not an expert when it comes to this particular niche, but I am a lover of good, loud music and if it's good enough for me, this amp is good enough for 99% of folks out there. The amplifier is about 2/3 the size of your average smartphone, albeit a bit thicker. The case is painted metal; it has spent a bit of time in my backpack and pocket and so far, the finish has held up very well. It has also survived a few drops, it still functions properly and looks no worse for the wear. The knob has a heavy detent when clicking the amplifier on, and rotates smoothly with a confident amount of resistance. The connectors hold the 3.5mm cables in place firmly and have a satisfying snap into place. There is a small switch for going between low and high-level inputs which I have not had the chance to play with. Around the back of the amp is a charging port with a small indicator LED to tell you when it is full or charging. The MicroUSB connector (Sorry, no Type C) isn't showing any signs of fatigue yet and still holds the connector tightly. I am always dubious of stated battery capacity claims, but regardless of the ratings, I'll say I've used it for 6+ hours while flying cross-country and on layovers, without it dying on me. I haven't run it dry in the field yet. My sole complaint is the included 3.5mm cable. It was too small to fit tightly in my other devices and would not work properly unless pressed. This was not an issue for me, though, as I used cables I already had on hand. If you need a cable to connect the amplifier to the source, I would recommend throwing one of those in your cart also. Overall, for the money, this little guy is a great item. When I purchased it, I figured eh, why not? This is gift card money and if it breaks, I'm out $30. I am happy to report that this was not money wasted. If you have a set of headphones you want to unlock more potential from, but don't want to spend big money, the Neoteck is for you.

Amp is real decent, it would be great if the aux cord wasn't junk DO NOT! buy this amp unless you buy another aux cord it wears down real quick and makes you regret buying it

Working fine nice n loud.

Personnellement, j’ai utilisé cet adaptateur pour prolonger les câbles Jack, j’avais plusieurs câbles de 5 m et ça m’a permis de prolonger un son de bonne qualité et sans perte. Je recommande donc fortement ce produit. Il est vraiment de bonne qualité et en métal qui plus est ce qui lui donne un style assez cool.

Groot verschil bij wel of niet gebruiken bij smartphone. Goed volume en prima geluid! Ook makkelijk met ingebouwde accu.

Este producto me ha sorprendido. Es muy bueno y tiene mucha potencia. Lo tengo puesto para la salida frontal de auriculares del PC. Uso las salidas de uno u otro lugar según determinadas cosas y ya para jugar directamente unos cascos Logitech. Pero necesitaba dar volumen a esa salida y lo he conseguido. Da mucha mucha potencia. El ruido que se oye al ir subiendo el volumen es porque lo tenéis conectado a la corriente para cargarlo mientras lo usáis. Se desconecta y listo. Otra cosa, cuando tiene poca batería casi no amplifica, parece que se ha estropeado, pero no es así. Comprobado. Este mismo aparato lo hay con bluetooth y pensé cogerlo, pero es que no voy a llevarlo con el móvil para escuchar música por la calle. Si es para usarlo en casa vale, pero cargar con más peso no. Así que coged el que is vaya mejor o según la oferta. El pero que puse es que el cable jack que viene es muy aparente y bonito, pero se han soltado los conectores al desenchufarlo ayer para limpiar un poco la caja del PC. Dos semanas y solamente se desenchufaron dos veces contadas. Parece que el cable venía mal de fábrica pues se cayeron ambos extremos. Al final un cable nuevo pedido en amazon. Poned un cable bueno. Lo agradeceréis. Tendréis menos ruido seguro. Su cable era bueno en conexiones pero muy frágil. Una pena porque no lo encuentro suelto.

This is ideal for the phone and tablet to listen to music in stereo. fits well in the shirt pocket.

Per gli amanti della musica che usano anche gli mp3, tanto invisi da alcuni audiofili ma praticamente ottimi se ben fatti, si va spesso in contro al volume insufficiente, soprattutto per mp3 creati da opere di una certa età, e ancor più se ascoltati con cuffie di qualità per le quali nessun lettore mp3, anche di gran qualità, prevede la necessaria potenza, anche a causa di norme legislative che impediscono di produrre lettori che superino una certa pressione sonora. Naturalmente senza indicare con quale tipo di cuffia questa pressione deve essere raggiunta (sic.) Sono quindi entrati in produzione questi amplificatori da interporre tra il lettore e la cuffia. Inizialmente ero un po' timoroso perché non è in classe A, ma i timori si sono vanificati all'ascolto: l'amplificatore funziona bene, ha due posizioni di amplificazione, normale ed extra. Ed io uso quasi sempre la posizione normale più che sufficiente per la maggior parte dei brani. Certamente per la tendenza attuale che mette la comodità come priorità innanzi tutto, usando blue tooth e addirittura cuffie che possono memorizzare brani nelle loro memorie per non usare nemmeno il telefono, non si sposa con questo sistema, in quanto il lettore va collegato via cavo così pure la cuffia, ma se non si fa troppo i sofistici, il sistema è comodo e certamente portatile. L'autonomia della batteria interna è ottima tant'è che non so quantificarla, avendolo usato parecchio prima di ricaricarlo. Sicuramente risponde ai dati indicati.
