A headphone's fit can make or break your workout. How many times have you lost an earbud or had to pause your workout because the cord was yanked out? Fit and security are always important, but it's even more so for sprinters or people who run trails with uneven terrain. No matter your speed or footing, the Soul Electronics X-Shock Absolute True Wireless Earphones ($60) will stay securely in place from beginning to end. As a result of their ergonomic design, runners are able to custom fit the ear tips and buds to the insides of their ears. There are also no wires, bands, headsets, or ear handles that'll get in the way of you and your run, as another added measure of security.
