Motorola SF700
Motorola is launching two new sports headphones with built-in heart rate monitor – the wireless SF700 and the wired SF500. Both of them are equipped with in-ear sensor to detect your heart rate, meaning there’s no need for a chest strap. They provide one-touch heart rate read outs to ensure you can monitor your workout closer than ever before.

Motorola SF500
Designed to use with the MOTOACTV, the SF500 and SF700 can transmit the heart rate information for your workout to the fitness tracker.
The SF700 comes with built-in microphone and controls for making phone calls, while the SF500 has in-line remote control for music playback and calls. Other than MOTOACTV, these sports headphones also work on other devices such as mobile phone, tablets, computers, MP3 players/PMPs.
