JayBird has announced BlueBuds X ($170), a new pair of sport Bluetooth earphones. BlueBuds X are secure-fit, micro-sized earphones, offering eight hours of battery playtime. Listeners benefit from in-ear white noise reduction and Shift, a “custom implementation of the native Bluetooth SBC codec,” a feature that JayBird claims will enable BlueBuds X to rival top-notch wired headphones for purity and sound.

The X-Fit option allows users to wear BlueBuds X over or under ears. Voice prompting, a microphone for calls, and integrated controls are also notable features. BlueBuds X comes with three pairs of ear tips and ear cushions, a standard micro USB cable for charging, and a carrying case. It is available now in black or white.
