Bluetooth Amplifier Wireless Receiver Digital Home Audio Review

Powerful enough to produce (small) room-filling sound on a pair of good speakers and a subwoofer. I would give it 5 stars (and pay $10 more) if it had a line. Anyway, I need to add a buck converter to pass the speaker level signal to my powered subwoofer. Manufacturer's Note: There is no need to add a low-pass filter to the line output. Subwoofers tend to only let through low frequencies, so a simple line-out will suffice.

I really like the compactness of this thing.

When I moved into my house, the speakers from inside the house were connected to my back porch through the ceiling. I turn on music from my phone while relaxing in the garden.

I'd rather not hear the digital voice announcing the connection—sometimes I just don't want to be reminded that I'm interacting with a computer. And…

I have an old pair (2004) Bose outdoor speakers. They just sounded like the radio station had never been shut down.

The connection was easy: plug in, connect speaker cable - BOOM, done. Search for FOSI under Bluetooth on the mobile phone and you're done. The entire installation took less than 3…

This thing works as advertised. The Bluetooth connection works very well. The small size makes it powerful. What is greatly appreciated is that it comes with its own power supply. Nice gesture. It's unboxed, although I like the on/off button. I have a couple of these mini amps that don't have this feature. Unfortunately, it doesn't have bass/treble controls. You must use the equalizer controls of your audio source such as smartphones or tablets. The only thing I'm not sure about is the…
