Fosi Audio Replaceable Orange & Grey Knob

Very pleased with my purchase

I'm really happy with my Fosi Blue Tooth amplifier. I bought it to use with a pair of Polk bookshelf speakers as my garage stereo. The quality of sound is very pleasing and the ease of use is fantastic. I had a different class D amp in use and the Fosi gave me a noticeable improvement in sound quality.

Knob upgrade

Changed my knob color to orange to better match other Fosi equipment in my collection. Super easy to change. Thanks Fosi!

Orange Knob

It’s a knob! Obviously no performance changes but it sure does look pretty!
