Low sound quality. Disconnects while swimming. Water enters while swimming

Great sound and I can run or work with it but not perfectly comfortable fit in the ears. Also looks like the wire cord will be problem soon so I will put cover coil on it.

Purchased for use as both a running headphone and for occasional use with voice function. When running, the lack of sound quality mid-range and bass makes the music sound washed-out and reminds me of a laptop speaker or base-model car speakers (think 90's era american-made sedans). When not listening to music or taking a call, there are two issues: poor background noise filtering and the power-off feature. Initially, every 5 minutes on a normal volume call with fairly constant speaking, the headphones would turn off. Now they just turn off after 5 minutes even if I have music playing. Did anybody ever bother to write a test specification before the design of the UI and microphone internal to the headphones were approved and started manufacture? If so, they should probably do something else. If not, the product manager may benefit from familiarizing themselves with the basics of consumer electronics and engineering.
