RHA’s CL2 Planar Headphon

Independent audio company RHA has released the “world’s first” planar magnetic wireless headphone, the CL2 Planar. Developed by RHA over four years, the 10-millimetre driver consists of a planar coil and 16-micrometre diaphragm perfectly suspended above two matched magnetic fields, providing unprecedented audio performance.

“The combination of industry-leading technology and remarkable materials used in the CL2 Planar results in a headphone like no other,” says Colum Fraser, marketing manager of, RHA. 

The Product Design team at RHA developed the CL2 Planar taking inspiration from the aerospace and fine-jewellery industries, using zirconium dioxide to create near-indestructible, flawless housings for the CL2 Planar.
