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.
The Good The Sony DR-BT160 Active Style Wireless Stereo Headset allows for wireless audio streaming and music playback control with a compatible Bluetooth device. Sound quality is good.
The Bad The Sony DR-BT160 Active Style Wireless Stereo Headset is pricey, and the neckband isn't adjustable, which can cause fit and comfort issues. Call quality is only so-so.
The Bottom Line The Sony DR-BT160 Active Style Wireless Headset is a good option for gym rats who want to cut the cord between themselves and their wireless music devices, but business-minded users who are picky about call quality should steer clear.
