Input:
I purchased two of the J3 Earphones at the same time. One lost volume in one ear within hours of being used (running on the treadmill). The other lost volume in one ear within 5 months (used for walking). While Jlabs customer service is truly excellent and it was a super easy process to get replacements shipped for free I feel like it's just a matter of time before the replacements stop working properly. I would not purchase this brand again because I don't trust that it will continue to work well. Jlabs does appear to be aware of this issue.

PROS: Excellent sound quality and good price
CONS: Volume in one ear stops working suddenly
