Review on JLab Audio Fit2 Sport Earbuds - Gray/Pink: Sweatproof, Water Resistant with Adjustable In-Wire Earhooks | Guaranteed Fit & Lifetime Warranty by Joy Berry

Why headphone designers fail to understand a simple fact: Sweat flows down cables. This product is advertised as completely waterproof; They even offer to rinse it under the running water. But like every other pair of headphones I've tried, the mic and control button gave out after a few months of training. The head gets hot, salt water runs through the cables to the microphone and button, and everything is short. At first the button failed, then it started sending "volume down" signals to my phone. In the end the microphone broke so no one heard me when I called. The sound is ok, but nothing special. Rigid wires around the ears are more annoying than helpful. But I would put up with these things if only I could buy headphones that would survive six months of intense warm-weather training.
