Fitness-friendly headphones come in a variety of shapes and styles--from earclip to behind-the-neck--and finding a pair that stays put on your head while you're active can take some trial and error. Once you get past fit issues, you may find yourself wanting some more advanced features, and built-in Bluetooth technology often tops that list, as it eliminates the need for cumbersome wires tethering you to your MP3 player. The latest pair of active-style earphones to hit the market is Sony's DR-BT160 Wireless Stereo Headset, which comes in two models: the $130 BT160AS, which includes just the headphones, and the $180 BT160IK, which also throws in an iPod adapter. It's a pricey solution, but those who can get a good fit will be rewarded with good wireless sound quality.
About fit: the Sony DR-BT160 headphones are not adjustable, so it is going to be an issue for some users. This reviewer, with her abnormally small ears, certainly had a problem getting the headset to feel secure and comfortable. Other testers had better results, though. The DR-BT160s have a pretty typical behind-the-neck design, with a band that loops over the top of the ear and earbuds that are inserted within. The Bluetooth power and control modules are somewhat triangular in shape and rest behind each ear. The left contains the battery and a port for charging, and the right houses the controls: a pairing button, a call-answer key, and a joystick that adjusts volume and skips tracks. The joystick may also be pressed in to play or pause tracks; this particular control is a bit awkward, but other than that, we found the toggle handy and responsive.
