NS-10G Bluetooth 5.0 2 Channel Power Amplifier HiFi Stereo Audio Mini Amp Wireless Receiver 50Wx2 for Home Speaker with USB & Bass Sound Effect (Black)

i havent tested it for a long time. but for a quick 5 minute test it was good and sounded good, so no problem so far, plus it had quite a nuber cables

I expected a small amplifier but this is amazingly tiny. I can’t believe they can pack 50 watts per channel in such a tiny amp. I specifically bought this to replace a Pyle amp that was irritatingly noisy. It is used for a pair of Aurasound Cube speakers. It drives them beautifully and the convenient input jack links directly to my recording interface so I can easily switch between my main studio monitors and the Cubes. So nice I no longer need to put up with the Pyle noise. A great addition to my home studio.

I bought an NS-10G in 2017 for occasional use. Due to a move in early 2020 it became my primary amplifier. I'm impressed. Speaking as an audio engineer I think this design beautifully balances the tradeoff between low cost and features/quality. Of course it's not super high fidelity or high power, and the Bluetooth reception range seems to be limited if there's anything in the way, even just a bookshelf. But the self-noise seems very quiet; it's not noticeable to me unless I listen very carefully for it. For background music using existing speakers, taking little space, and costing next to nothing (for audio gear), I think this tiny thing is amazing. I took off a star because the power button broke a couple of days ago, after four years of use, due to a design flaw (high-profile surface-mount momentary-contact button exposed to strong shear force when pressed). But after looking through dozens of replacement options, I decided to buy another NS-10G. I need both USB and Bluetooth input and I really want the USB in the back for cosmetic reasons. NOTHING I found balanced these features with quality and low cost as well as the NS-10G. I'll just push the power button as gently as I can. UPDATE: The replacement failed within a few minutes of power-up. "Infant mortality" we call it in the biz. Guess they don't do a lot of testing before they ship? If the next replacement also fails I'll have to change my glowing review :(

This is a great, very small, low cost, digital (class D) amp capable of driving regular speakers. You not only get the amp, you also get a separate power adapter (60W) and all of the interconnecting cables you might need. All of the components are very high quality. I use it to drive a couple of Tang Band 4" full range speakers in place of a sound bar for a UHD TV. In Bluetooth mode it is easy to connect to and sounds great. Just make sure you read the manual about using the two control buttons, it takes a long press of the power button to turn it on. The only change I would make is to have the bass boost feature work for the AUX line input mode, right now it is designed to only work with the Bluetooth mode.

I purchased two of these amplifiers for a sim racing setup. They worked fine for a few weeks, then all kinds of problems would show up. First, sometimes when I restarted my PC, my labels on these USB connections (left/right) would get swapped. So my sim racing would vibrate on the left when it should have been on the right. I would go into my settings, swap the labels (again), and then it would work. About 2 months ago, the amplifiers would just intermittently stop working. They would still appear as a connection on my PC, but when I would test the output, no sound would come out. Sometimes, completely unplugging everything and plugging it back in again would reset the device. Sometimes it didn't. Then last week, both of them stopped working completely, but exhibiting different behavior. When first used the amplifiers, if the USB port was turned off, then amp would also turn off. Then suddenly, one amp would stay on no matter what, even if the PC was powered down or the USB port was turned off. The other amp would follow the normal behavior of turning off with the PC when the USB port was powered off. The amp that powers off with the PC appears as a USB connection, but the amp produces no sound. The amp that does not power off doesn't show up as a USB connection at all. It is completely dead. After 3 months, having both units flake out like this is not promising. I am switching to a different setup with a higher quality amplifier.

Great little amp. I primarily use this for bass shakers for sim racing and the occasional movie so can't comment specifically on audio quality of the amp. For tactile transducers however, this little amp pumps out a strong and clean signal to drive the Dayton Audio BST-1 well. Very happy with its performance.

Nice sound fron a small inexpensive package. Beware though, their implementation of a USB sound device is incomplete. Although they rely on the Windows USB Audio driver, they ignore Volume control commands. So, when connected to a computer, you get a volume control and sound mixer by virtue of the Windows driver, and you can move the sliders up and down all you want, but it has no effect on the NS-10G. Likewise, the Volume up/down buttons on your keyboard have no effect.

Great quality audio and plenty of power (4ohm speakers) AND so inexpensive. Seriously…. How do they make it so compact and good looking. I would highly recommend these amps. Brilliant

This unit works extremely well and produce excellent sound - loud and clear

El producto llego rapido y sin problemas, si el envio es desde Amazon el producto llegara en menos de 5 dias, bastante razonable para el precio del mismo. La calidad del mini amplificador es muy buena, se siente solido y de buena construccion, sin piezas sueltas ni que se sientan debiles, una buena respuesta de audio con mis altavoces aunque hay que considerar que dado el limite de watts por canal, 50W pero sin especificar si son RMS o PMPO, al subir demasiado el volumen se distorsionara un poco el sonido sin embargo no es necesario subirlo tanto ya que a un 40% o 45% de volumen sera ya elevado para disfrutar. Definitivamente es una buena opcion si no se desea gastar tanto en un sistema de audio sencillo, pequeño y economico pero de buena calidad y gran sonido, seria genial tener un manual mas completo sobre todo de los efectos de audio al usar el bluetooth pero nada que interfiera con disfrutar de un buen sonido, solo un poco de prueba y listo.

Revivieron unas bocinas technics y suenan super

Bought 2 to use on a PC Sim racing rig. Amplifiers were great and delivered the promised power. The power supply on both though.... The power supply split on both on the plastic side exposing 240v internals while plugged in. In short, only by these if you have a supply available, and you do not intend to use the supplied power supply. The ones I received were dangerous. 4 Star because the Amplifier itself is good.

Working as expected!
