RHA CL1 Ceramic Earphones Review

What is the RHA CL1 Ceramic?

RHA has been steadily developing a full range of earphones at a range of price points but continues to focus on the more affordable end of the market. This means that the CL1 Ceramic is the company’s flagship at exactly the same price point where a manufacturer like Noble gets started. RHA has made a name of themselves in using aluminium for the bulk of their products but – as the name suggests – the CL1 makes use of something a little more exotic.

Design

The enclosures are made from Zirconium dioxide, a non-metallic and extremely non resonant material that is made in two sections and then joined together with an almost imperceptible seal between them. Inside this, the RHA uses two drivers but unlike the Aedle ODS-1, both of these are dynamic in nature. The first is a relatively conventional dynamic unit that handles lower frequencies. This then hands over to a ceramic plate driver mounted in front of the first unit that covers frequencies up to an impressive 45kHz.
