Nobsound 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)

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.

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!

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 .

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

Update 1/18/21:So the amplifier lasted for awhile but eventually started sporadically dropping audio for short bursts. Until it eventually just stopped working all together. As my original post mentioned this was all while underpowered at 50W with the included power supply, not the rated 100W. I have contacted the seller and will update as I learn more.Original Review:Not capable of supporting 100W power claims. I bought a separate 24v power adapter per the instructions since the included one is 12v for around ~50watt performance. The amp kicks on and off and is unstable when the volume is turned up at these wattages. I'm using these for two bass shaker transducers and it s seems adequate for now at 50w but disappointed I cant get the 100w performance promised. Will likely upgrade the amp in the future.

I was skeptical about this putting out that much power. My old school amp was 100 watts weighed about 80 pounds because it was full of copper wire. The one I currently have is a Onkio with built in tuner and it weighs about 15 pounds at 125 watts. This little thing fits in the palm of your hand! I used it to power some Sony speakers from a dead surround sound and an extra FM tuner . I tried just the 4 little book shelf speakers then realizing it easily over powered them added the wolfer and the mid range. I can get about half volume before they distort. I think it could handle larger speakers. The blue tooth works good if your phone is near it. The hardest part of this little thing is that it is so little! Hooking up wires is easy but a little larger unit with all the jacks in the back would be nice.

Giving it 4 stars because the BASS boost that they advertise doesnt do anything. The booklet states Bass boost is only for Bluetooth, but I couldnt activate it. Im still using it for my bass shakers because the PC recognizes it as a sound card and its more wattage output then my previous amp.
