The RHA CL1 Ceramic in-ear monitor is designed for use with headphone amplifiers or high powered DAPs and smartphones. The dual transducer configuration combines the precision CL Dynamic and dedicated high frequency ceramic plate driver for true-to-life sound. With a crossover configured at 8kHz, the ceramic plate driver controls high frequencies whilst the CL Dynamic transducer delivers unprecedented accuracy in bass and midrange frequencies.


Crafted from ceramic. Injection moulded ZrO₂ housings.
The ergonomic, high density housings of the RHA CL1 Ceramic are created using ceramic injection moulding, a complex seven stage process. This results in a striking, extremely durable in-ear headphone with low acoustic chamber resonance, eliminating distortion.


Detachable cables. Custom and secure design.
The RHA CL1 Ceramic features a detachable cable system using custom, locking sMMCX connections for contact efficiency and durability. The RHA CL1 Ceramic is supplied with RHA’s silver core Ag4x balanced cable with 4pin Mini XLR termination for use with Dacamp L1, in addition to a braided high-purity OFC cable with 3.5mm and 6.35mm terminations.


Premium cable construction. High grade materials for pure transmission.
The RHA CL1 Ceramic earphone is supplied with two cables. The Ag4x cable uses silver, a highly conductive metal, and is fully balanced; each channel, left and right, positive and negative, stays entirely separate from the the source device to transducer housings. This cable terminates in a 4-pin Mini XLR connection designed for use with the Dacamp L1. The high purity OFC cable is also channel separated to eliminate risk of cross channel interference, and features both 3.5mm and 6.35mm terminations for use with a wide range of audio equipment.


Perfect fit. Refined, mouldable ear hooks.
Featuring fully mouldable over-ear hooks designed to hold the headphones in position with the cable running over and behind the ear. The tri-material design can be moulded to the exact contours of a user’s ear to ensure a secure fit, and position the transducer housings for effective noise isolation.


Unique dual transducer configuration
In creating the RHA CL1 Ceramic in-ear monirot, RHA brings together two unique technologies. The ceramic plate transducer and the CL Dynamic driver collaborate for outstanding, high-resolution audio. The CL1’s unique ceramic plate transducer operates uses a technology that we have refined for unprecedented control over high frequency and harmonic tone reproduction.


High-Res Audio certified
