State-of-the-art Audio

The world’s first wireless planar in-ear headphone, these high-resolution in-ear monitors house one of the smallest planar magnetic drivers ever released, generating immersive audio with outstanding response and accuracy.


Style and substance define the injection moulded ceramic housings of the CL2 Planar. Both aesthetically beautiful and uniquely functional, the ergonomic shape fits comfortably for as long as you listen, and the material itself minimises distortion for crystal-clear sound. The distinctive shape also blocks external audio, guaranteeing a powerful listening experience with minimal disturbance.

Wired and Wireless

Supplied with our aptX™ Bluetooth® neckband and cables, the CL2 Planar can be worn wired or wireless and gives state-of-the-art audio experiences with or without the detachable cables. The flexible, silicone, 12-hour battery life Bluetooth® neckband ensures you can listen in comfort for longer. Also includes braided 3.5mm cable and a balanced, silver-coated 2.5mm cable.

Listen Everywhere

Completing this extensive package, the CL2 Planar also comes with a carry pouch and folding carry case to hold the 2.5mm and 3.5mm connection cables, charger, Bluetooth neckband and a range of Comply™ Foam and silicone ear tips, so you can listen and travel in comfort and ease.
