Sennheiser OMX 680 Sports Earphones (£44)
Kerry says: Flexible and shock absorbing, the Sennheiser OMX 680 Sports Earphones will stay put on even the hardest runs.
A short cable makes it easy to run with your mp3 player in an arm band, and with a volume control on the cable these headphones are ideal for runners who store their player out of easy reach.
High-output drivers deliver quality sound without filtering outside noise - perfect for runners, who need to be aware of their surroundings.
Its moisture protection system means you don't have to worry about sweat or rain damage - and can push on through summer storms like today's.
The lightweight neckband is comfortable yet sturdy, and the headphones simply won't budge. Plus, its reflective stripe provides visibility when the nights begin to draw in.
