Tribit XSound Go Bluetooth speaker. The bass is deep and mellow, not muffled or distorted. Crisp, clear highs but not hissy. Easy to set up and pleasing design. The first Tribit XSound Go speaker mysteriously died a few months after I purchased it. I emailed Tribit, returned the faulty speaker (the company sent a prepaid label, I didn't pay a cent to return it), and received a replacement speaker in 2 weeks. Excellent customer service! Polite, responsive, helpful customer rep. I would highly recommend this speaker, and I would definitely order another one.
I bought this because I was trying to replace wired speakers for my desktop pc. Paired with Iogear BT dongle. This unit sounds great, but it would respond to keyboard mute/volume commands from my Logitech MK710. I must have reinstalled the BT drivers a dozen times, never worked. So I put this in our bedroom. It responds fine to iPhone 8+ BT commands. 4 stars because it would not respond to BT dongle.
