LG's heart rate-tracking earbuds could arrive in the US soon

Back at CES, LG was talking up the Lifeband fitness wearable and a pair of heart rate-sensing earphones, but neglected to mention when we'd actually see them in stores. Thanks to the FCC, however, we can get a reasonable idea that the latter device will arrive shortly. Now that the Bluetooth earphones, packed with Valencell's optical heart rate-monitoring technology, have been deemed fit for human consumption, it shouldn't be too long before this gear is available to buy -- and we can get back to wondering when the Nike-troubling Lifeband will make an appearance.
