Just got myself a RIVA Turbo S and has fantastic sound for a "little" bluetooth box. It's bigger than most, but has a warmth and depth to the sound, a fullness of dynamic clarity that other compact bluetooth speakers fail to deliver, either on the low, mid or highs.
Played a live recording of Hotel California to use a recording that would really flex its auditory muscles and it shone like a lighthouse on a dark night.
"Another One Bites The Dust" is another of my favorite songs that feature a wide spectrum of sounds with a nice thumpy bass line.
Bumped some Tupac and it thumps hard as well with deep well rounded bass.
Currently i'm listening to a live Clapton, and its crazy how such wonderful sound can come from these little things.
Their batteries can go out. It seems to be a common problem. I bought a reconditioned one with the understanding it would not have battery capability.
Gimmicks. It has a "Turbo Mode" that "enhances the bass" and turns it up to 11. Well, it does, but it also adds volume so you can't really add bass with just the turbo mode.
It also makes a stupid turbo revving sound when you engage turbo mode.
Anyway. Carry on.
