The Fitbit smartwatch leaks out, promises 4 days of battery life

First off, the smartwatch is codenamed Higgs and is said to pack a built-in GPS, heart rate monitor, support for music services like Pandora, as well as the ability to make mobile payments. More importantly, Fitbit's smartwatch is supposed to offer four days of battery life on one charge.

The smartwatch will feature an aluminum unibody and will allow users to change its bands. Price-wise, the Higgs will cost around $300 when it launches this fall.

In the same piece of news, Fitbit plans to launch a pair of Bluetooth earphones, which care codenamed Parkside. You'll be able to wear them around your neck and very much look like Apple's BeatsX.

Fitbit's Bluetooth earphones will be available in two color options, Nightfall Blue and Lunar Gray, and will sell for $150. They should be launched at the same time as the smartwatch.
