Nothing says sport like yellow and the Sennheiser CX 680is are no exception to this rule. The EarFin design seems almost an afterthought but it does keep them in place and the sweat-resistant CX 680is are easy to fit, super-comfy and secure.
They're also amazingly light at 14g, but somehow muster an open, smooth and detailed sound. An acoustically closed design helps sound quality and blocks outside noise, and an in-line mic and remote let you make and take calls, change the volume and pause your tunes (but not skip tracks). The perfect partner for sporty music lovers.
Try the PMX 680is ($109) if you'd prefer a neckband design.
