this speaker is CRAZY good. I got it from public but for those who are thinking between this and the jbl/creative/lg ones, choose this one. The bass fills the room and when you're out its very clear and loud. I've had it for 2 weeks, I haven't charged it yet, I connected the app, it's wonderful. The ult function is crazy. I'm NEVER buying jbl again, you only pay for the name. with this speaker you get quality sound, and I tried both at the store but the sony is top tier. Same goes with their big ones, I tried both jbl and sony, and the sony won again. The jbl is more expensive and it's not as good, you won't be disappointed if you get the jbl, but I think the sony is way more worth it. When I got my sony earphones, after trying 100 jbl ones, I was blown away. Sony is best with sound, you'll remember me.
