Probably my favorite portable bluetooth speaker I own

I tried out 6 portable speakers:• JBL GO 2 Portable Bluetooth Waterproof Speaker, black, 4.3 x 4.5 x 1.5• Bluetooth Speaker,LFS Wireless Speaker Portable Loud Stereo Sound

Excellent Bluetooth Speaker

AmazonBasics Portable Wireless Bluetooth Speaker - BlackI tried them all out for sound quality, and the better sounding ones were (in rough order from best to least impressive): the Oontz, the Rock Space, the JBL, and (kinda surprisingly) the AmazonBasics.

This is a great bluetooth speaker
