Great sounding bluetooth 2.1 channel stereo amp. easy to setup. I used it to refurbish my Bose Acoustimass AM5. Ripped out the original amplifier in the bass unit and connected all the speakers (including the jewel cubes) as passive speakers.

I was previously using a small & cheaper BT 2.1 channel power amp with the same Texas Instrument's TPA3255 chip. However, Fosi Audio BT30D Pro works much better than the previous one. The difference is obvious. The only part I can point out is that the mid-range is slightly weak. It's a really good class-D power amp for this price range.

Fast postage powered me entire Logitech thx system when the internal board packed it in
Ordering experience was great, Delivery was quick, packaging was also great. Coffee included in it was a Big Surprise. The device is genuine, sound quality so far is unexpectedly good. Never expected such great sound quality from such a portable amp. If I need to buy any thing again in future, the audio store will be my 1st preference.
Nice unit, clear sound and perfect for a small PC sound set up. not sure that the output figures are correct though. not very loud at almost 12'o'Clock. still prefect for my needs.
Absolutely amazing for the price. Perfect for bedroom or smaller living area. The SQ is gobsmacking good>
This little thing is absolutely surprising for how small it is. I connected two Origin 8ohm outdoor speakers and an Ariel 12" 4ohm sub and my garage is rocking! I wish the bass gain was a little more but I cannot complain. This is going in my work van with 1 sub and 2 door speakers.
Sounds great and is very powerful. I knew other recommended this brand and they were not wrong. A great choice.
