I love riding in headphones and theres nothing quite like a soundtrack to your shredding or a podcast to elevate your long rides. However, I'm not a fan of earbuds because I worry about losing them. My earholes seem particularly reluctant to grip the buds, so these bone-conduction headphones with a neck band seem as though they could be just the job.Cleverly, the bone-conduction technology works by vibrating the bones of your head instead of the air in front of your eardrums. Unlike regular wireless earphones, they sit in front of your ears, leaving them open and free.They also weigh a scant 29g, so they should be as unobtrusive as possible!The Shokz headphones are water-resistant to deal with the wet weather were going to be experiencing this autumn and earned a place on our list of the best headphones for cycling.Buy the Shokz OpenMove wireless headphones with a 31% saving from AmazonRemember, you need to be signed up toAmazon Primeto take advantage of these deals.
