A unique moisture protection system allows you to rinse the headset under the tap to remove grime and perspiration.

Q & As

Sennheiser/Adidas PMX 685i Sports In-Ear Neckband Headphones with Microphone, Black 4 5 2 2
Good all round performance I'd been struggling to find headphones to meet my needs with regular smartphone in-ear ones seem to drop out too easily and only sound any good when pressed into the ear. Over-ear headphones are too clumsy to wear whilst cycling and a little too sound insulating at work. These headphones are just right. The design lightly pushes the ear-piece into your outer ear and stays snuggly in place no matter how much you're moving around [also don't get in the way of wearing cycle helmet and buff] - in fact moving your head around helps to seat them in place. The sound is crisp and positive with a surprisingly strong bass. Also there seems to be more volume available compared to others using the same source. 11 February 2014
Great head phones but break to easily I bought these for running and doing Skype calls at work, the main requirement was a good mic and controls and that they would filter in enough sound so you could hear yourself talk. I absolutely love them and they do everything I want, however after 2 weeks of ownership and they're broke! Basically I caught the cable whilst running and the earphone arm snapped, boo hoo! So if you buy a pair be very careful with them as they seem to break very easily, for me its back to earbuds again and that unnerving experience of not knowing if you are talking to loud or too softly when you are having a Skype conversation in a quiet office.... 28 April 2013
