I just got a Clip2 last week. I've only used it in a quiet truck, but it seems to be plenty loud. Sound quality is everything you'd expect from JBL. I have not tried to run out of battery, because my phone actually can't push bluetooth for 8 hrs. The materials are nice, a silicone back and a soft fabric front. But I suspect they will not wear well in our environment.With doors open and going down a hwy wondered what worked good
Saw this wonder if it would work
