RHA CL2 Planar

Revolutionary planar magnetic technology

The CL2 Planar is built around the smallest commercial planar magnetic driver ever released. A 16 micrometer-thin diaphragm and planar coil are suspended perfectly between two matched magnetic fields, resulting in control beyond the capabilities of conventional driver designs. Four years in development, CL2 captures the precision, response and accuracy of planar magnetic technology, perfected for the first time in 10mm driver – allowing for fully portable, high fidelity audio.


Injection moulded zirconium housings provide both low-distortion audio transmission and a breath-taking aesthetic. With applications ranging from synthetic diamonds to medical-grade implants, zirconium is an incredibly durable ceramic compound the maintains its complex structure despite constant use. An injection moulding process – wherein the material is heated to over 1400°C in order to reinforce and purify it – is used to achieve the distinctive, precise shape on the interior and exterior. Using this process provides both a comfortable, unobtrusive fit and crystal-clear audio transmission.

Detachable housings – the world’s first wireless planar headphone

A detachable design using MMCX connections, the CL2 Planar comes with a 12-hour Bluetooth® cable compatible with high-fidelity aptX™ streaming, a 3.5mm oxygen-free copper (OFC) cable and RHA’s balanced, silver-coated Ag4x cable with 2.5mm connection. RHA’s SecureFlex cable, a fully flexible Bluetooth™ neckband, is compatible with any MMCX housings using an ear hook design. Compatible with aptX™ and AAC streaming, the CL2 Planar can be used for 12 hours of playback. Both the 3.5mm and balanced 2.5mm cables use high purity OFC cores to transmit analogue audio signals without distortion.

Listen everywhere

The CL2 Planar includes a folding carry case, designed to carry all the cables and accessories you may need. For an even more portable setup, a weather-proof carry pouch is designed to house the headphone in your chosen configuration.
