Heart rate-tracking in-ear headphones are starting to pop up on the regular it seems. A couple weeks ago, SMS Audio revealed its collaborative effort with Intel, and now Jabra's joining the fray, but without the tether. In an effort to limit cord tangles, the audio outfit's Sport Pulse wireless earbuds connect to your phone via Bluetooth for sorting tunes and tracking your pulse. Dolby sound handles the listening duties while an in-line remote wrangles those mid-run track changes. Inside, an optical, biometric heart rate monitor keeps tabs on your workout, beaming collected data to the Sport Life companion app and peppering your activity with personalized coaching for added motivation. And as you might expect, the software helps plan workouts and logs info from each session. The wireless set goes on sale October 1st for $200 (£200), but you can pre-order now if you're unable to contain the excitement.
