I think I finally found the speaker I was looking for for using in the gym to exercise with. Since there's currently electricity problems there, this speaker with its own built in battery will be ideal. Sound quality is good, especially when not opening the volume full blast. Just a good volume sounds best. I like the knobs you can turn as opposed to just press. But the bass isn't very loud, which some people might miss. Still, not bad bass and not bad sound, especially for a rechargeable battery speaker.
