Earphones can sense pulse of wearer, pass data to smartphone app
Earbuds capable of sensing the wearer's heart rate from LG have passed through the FCC, ahead of a possible release in the United States later this year. The Heart Rate Earphones, audio devices that appeared at CES in January alongside the Lifeband Touch, are able to monitor the wearer's pulse and feed the data back to the wearer through an accompanying app.
Using an optical heart rate technology from PerformTek, Slashgear reports the headphones can monitor the changes in blood flow in ears to deduce the pulse, though the technology is also capable of providing the speed, cadence, pace, and VO2 max of the wearer. The earphones then transmit the data to a smartphone over Bluetooth using a clip-on accessory, at the same time as streaming music to the wearer and working as a hands-free kit. While it will work with LG's own Fitness app, it will also provide data with MyFitnessPal, MapMyFitness, and RunKeeper.

LG did not reveal when it will be launching the Heart Rate Earphones in the US, aside from sometime in the first half of 2014, and has yet to advise on its price.
