AKG K 840 KL

The AKG K 840 KL is a pair of on-ear, mini headphones that uses Kleer wireless technology to steam audio. As an improvement over conventional Bluetooth, Kleer wireless technology can transmit further and, more importantly, stream uncompressed 16-bit stereo audio with a lot more precision and accuracy.

Plus the integrated battery can last a whopping 2 weeks without requiring a charge. Also featured is a special 3D-Axis2 folding headband for convenient storage. There is however no microphone, which makes the K 840 KL only useful for listening to music.
