If you've heard of plan magnetic headphones before, it has been in the context of big over-ear models or Audeze's unique iSines, and none of them provide practical portable use. Well, at IFA this year, Scottish Earphone Specialist RHA will launch the first wireless i-ear flat magnetic headphones as it duplicates CL2 Plans.
Externally, the CL2 keeps RHA's famous look and shows no external signs of the new technology inside. With three cable options – one of them is a wireless headset setup with USB-C charging – these look just like a polished pair of flagship earphones similar to AKG's $ 1
But the interior is where these new ears are set to separate themselves. The ultra-thin 16-micrometer membrane in CL2s is part of the most compact plane magnetic driver ever released, which took RHA four years to develop. The earphone of each earplug is made of rip-resistant zirconium dioxide, which sounds like the same ceramic material used in RHA's former high-end pair, CL1 ceramics.
Using a standard MMCX cable connection, CL2 Plates comes with a pair of powerful braided cables, one ends in a 2.5mm balanced connector and the other features the classic 3.5mm plug. Their wireless neckband options are exciting, promising 12 hour battery life and a flat-to-full charge in just 1.5 hours. The maintenance requirement is impressive when considering that flat magnetic headsets usually require more power than conventional dynamic drivers. Unfortunately, when it comes to wireless standards, only AptX and AAC support – no AptX HD or LDAC. The highest audio quality you get from these will definitely be by using an old school-connected connection to the source of your music.
I will try the CL2s for myself at IFA, but if you can not wait until then, they are available to pre-order today, with full release kit for September 12th.
