House Of Marley's newest headphones are made from Forest Stewardship Council certified wood, recyclable aluminum and fabric made from reclaimed hemp, cotton and water bottles.
Other than being made from sustainable materials, one of the main features of these headphones is the Bluetooth capabilities. So it's 4.1, but also uses less battery when it is enabled. The headphones can also block out 4G signals, which can sometimes interfere with a Bluetooth connection.
Other specs: there's a 10h battery, they are foldable, have a removable and tangle-free braided cable, an in-line microphone, single button remote, and 50mm dynamic drivers for you know, the sound part.
The House of Marley Positive Vibration BT come in Black, and sell for $99.95. We haven't tested them out yet - but when we do, we'll let you know how they sound.
