Nobsound Mini Bluetooth 5.0 Power Amplifier - Stereo Hi-Fi Digital Amp 2.0 Channel 50W×2 with AUX/USB/Bluetooth Input - Wireless Audio Receiver - PC Sound Card incl. Power Supply (Silver) Review

This should get 0 stars. If you plug the power cord directly into a wall outlet or through a surge protector, the charger will make an audible "electrical noise" that lasts for several seconds after disconnection. It's like an electric fire waiting to happen. A cheap amplifier isn't worth a house fire. Very disappointed and would not recommend to anyone. Revain says the replacement will be shipping in a month, so I really kick myself for lowering the price. I've learned my lesson and I hope you

This was purchased because my first one restarted intermittently in the middle of the day and I hear the startup melody. Well, two days after I hooked this up, I started hearing that it does the same thing. I don't think they should stay in all day. And I really wish they would let you disable startup sounds because they're loud and annoying. If you plug a cable into the Aux port it will tell you, and if you unplug it it will tell you that you are back in Bluetooth mode. I'd rather have a…

Needed for some old Sony stereo speakers, flea market, stereo is long dead actually called?) I'm not sure if there is such a thing these days but I guess they don't have t. Since there were no connectors I just used bare wires to connect to the internal banana plugs. Man these things howl! Those vintage Sony speakers from the early 80's sound great! I think I paid maybe $5 for the whole stereo when it actually worked in the mid 90's, now I just use my iPhone for the bluetooth connection…

Out of the box this only plays music at an *extremely* low volume before shutting down, doesn't register with my computer's bluetooth (my phone only), and the power adapter caught fire when connected. When testing the bunk, the adapter only drew 2 amps. I replaced the included power supply with another one and it works great - all issues have been resolved. I'm still debating whether it's worth returning and getting a better one with parts that actually work. Sound quality isn't fantastic, but…

The build and finish of this tiny amp is fantastic and exceeds my expectations for the price. I'm amazed how they managed to pack so much power and functionality into such a small device. I can't talk to BlueTooth or AUX power as I use this amp as an external USB sound card to power two Dayton bass shakers connected to my racing simulator. No drivers were required and it was incredibly easy to set up in SimHub with LPF, eliminating the need for crossovers. The power of two shakers is more than…

I bought this unit to replace a similar product that no longer works. At $32, it was half the price of another device. Unlike the other unit, it didn't have bass and treble controls, but I figured I wouldn't need it anyway. It turns out that the sound quality (especially in the lower frequency range) is not as good as another device. But the real reason why I'm disappointed with this product is the Bluetooth range: I have an amp right in the house and play music with it on my patio (rather…

This little box is great! I've paired it with Yamaha NS-AW190BL indoor and outdoor speakers and while I'm sure this amp won't push them to the max, it's certainly powerful enough to produce a clear sound. I set up an outdoor theater in my backyard and hooked it up to my projector so I could take it inside when I wasn't using it. The problem is that for some reason this device introduces a delay of almost a second. When we watch a movie, the dialogue looks synchronized because the audio appears…

To be honest I can't believe how much performance this little device packs. It's even smaller than I expected! In addition, it has built-in Bluetooth, so I don't have to use a dongle or additional receiver! Admittedly the BlueTooth range is pretty pathetic (15 or 20ft at MOST and pretty doubtful any closer if you're out and about) but for simply putting your phone on a wireless charger on a patio. Listening to music is fantastic. I also appreciate banana plug cable receivers instead of flimsy…

Reviews that say it's "amazing for the size and price" are more likely to be true. Apocrypha. As for the USB DAC, I'd definitely say it's pretty decent and does its job well overall. I have this amp set to 1/4 on the volume control and it is good enough for basic room listening, with little noticeable distortion and no obvious clipping. Rear panel connectors work with both spliced cables and banana plugs; I reused some existing decent audio cables and it's funny how they pull down a small…
