Bluetooth headphones are great, they eliminate the annoying wires of traditional headphones and work with any Bluetooth device. This makes them extremely versatile and you don't need to have your Bluetooth device on you at all times. This means you can have your device charging in the other room and still be able to listen to music etc. Not that long ago we took a look at LUXA2's Lavi S Bluetooth headphones, they were a sort of mix between a set of headphone and a Bluetooth speaker. Well LUXA2 has sent us their Lavi D, which is purely a pair of Bluetooth headphones. LUXA2 tells us these headphones are made for listening to music and have state-of-the-art 40 mm drivers to bring you the best sound possible. Are these the Bluetooth headphones for you?
