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 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'd recommend this. It performs as well, if not even above my expectations. However, there are a few things to note: >The green led is always on, even after I power down the adapter. I suppose the voltage is coming from the USB input. >The bluetooth audio isn't as good as a direct connection or even the built-DAC thru the USB. >The volumes do differ between the inputs. But overall, I'd recommend it to drive efficient smaller bookshelf speakers. I've not tried it on floor standers as yet, but I suspect it may challenged to drive much bigger drivers. I'm currently using it to drive about 20 year old KEF coda 10s; which aren't very efficient, but the little amp really does the job well.

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.

Just received a few moments ago and I’ve already hooked it up with a pair of Sony bookshelf speakers. Setup was very simple and so far it sounds great. I’m actually impressed by the ease of the Bluetooth pairing with my IPhone 8 and the range. Much quicker than my Jabra Soulmate speaker and I’m sitting outside on my patio with the unit inside on the dining table-not the permanent location-and it hasn’t dropped or skipped once. I don’t think this little amp would ever rock the house but I really like it so far and it was soooo cheap! It remains to be seen how the auxiliary jack and USB port perform. I’m going to test my Chromecast Audio in the aux jack later and see what happens. Also kinda cool that it comes with all the cables you’d need to hook it up to a device, because I’m usually digging through my cable boxes in the garage when I want to hook up a new toy.

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.

Easy to use

I got this guy powering 2 truck behind seat speakers with 10 inch woofers and 3 inch tweeters and they play loud. It’s hard to believe considering this thing is half the size of a pack of cigarettes. I doubt it puts out advertised watts but it works fine especially when considering price .

First, the power supply you use has the biggest impact on the volume and sound quality. It will accept from 9 - 24 vdc - the closer to 24 vdc, the better. I have a number of 19-20 vdc power packs left over from older, discarded laptops - perfect for powering this thing! If you can put together a 24 vdc power supply, so much the better. Just power it with as much voltage as you can - up to 24vdc. That provides you with the cleanest, rail.-to-rail signal you can hope for, anything more than rail-to-rail will only create distortion. As for performance, I can typically maintain a bluetooth connection up to at least 20', sometimes it errantly reconnects up to 40' - usually when I don't want it to, but more than adequate. Sound quality is typically as good as your speakers will deliver, unless you overdrive it (Refer to previous power supply suggestions). It is always ready and eager to connect up via bluethtooth. It has a helpful powering on/ connecting audio that let's me know it is there - just go to settings and connect, if it hasn't done so already. I have a couple of these imbedded in my porch ceilings so that if I go out to listen to streaming or music, I'm set to go - no problems. I'm in need for another, and this is what I'll get - if some puke steals it off my porch, oh well, the speakers costs a lot more!

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.

Connected this Bluetooth amp to a pair of Minimus 7 bookshelf speakers. Connection was simple. The unit is ver small. Bluetooth connection was solid and the sound quality was very clear and loud. I would highly recommend this unit for this purpose.

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.

I was sceptical buying such a small/inexpensive amp but it was for my father's bbq area and he LOVES it. Good sound for the price, and it's so small the plug pack is bigger than the unit!
