A speaker in my first pair died less than 12 months after purchase with irregular use. After running in the rain for the first time, the volume control buttons no longer work and the play / pause button is now highly temperamental. So much as the product being water resistant and sweat-proof. Additionally I highly doubt that other products in the range are able to be washed under running water as advertised.

The sound is pretty good for in ear phones, not had chance to use them whilst doing exercise but are excellent on my commute.
