I'm a music fan, What is the sound quality of this product?

Asked by: Hussca
Sound quality is great. The Volume is really bad though. Not very loud at all.

Just purchased the Sport JBL flexible Earphones and callers cannot hear me when I'm speaking. Can you help me troubleshoot?

Asked by: SSCOLE
Have you tried taking the end out of your ear that has the controls and talking directly into the rectangle? The microphone on mine is in the back side of the "control box". People say they can hear me fine when I talk into the control box. Works great when you get a call while listening to music. Its certainly not designed to be a primary bluetooth for calls. I do see people walking around with one end hanging down, at times.

Is there any water resistance?

Such as if running in the rain, or profuse sweating during training?
Asked by: Sigma
The UA Sport Wireless Headphones are water resistant and sweat resistant, however continuous exposure to water over an extended period of time may damage your headphones. NOTE: Do not swim with these headphones and use caution when storing your headphones as the case is not waterproof.
