In-ear headphone with dynamic and ceramic transducers

RHA CL1 Ceramic

The dual transducer configuration combines the precision CL Dynamic and dedicated high-frequency ceramic plate driver for true-to-life sound. 

Introducing the CL1 Ceramic
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.The CL1 is designed for use with headphone amplifiers or high powered DAPs and smartphones.
Dual transducer configuration 
Absolute Sonic Precision
The CL1 augments the performance of RHA's CL Dynamic transducer with a dedicated high-frequency ceramic plate transducer for precision sound reproduction. The CL Dynamic transducer produces pure, accurate tones below 8kHz while the ceramic plate transducer generates enhanced harmonics in extended treble response.

Injection moulded ZrO₂ housings
Crafted from ceramic
The ergonomic, high-density housings of the CL1 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.

Custom and secure design
Detachable cables
The CL1 features a detachable cable system using custom, locking sMMCX connections for contact efficiency and durability. The CL1 is supplied with RHA’s silver wrapped 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.

High-grade materials for pure transmission
Premium cable construction
The CL1 Ceramic is supplied with two cables. The Ag4x cable uses silver, a highly conductive metal, and oxygen-free copper, and is fully balanced; each channel, left and right, positive and negative, stays entirely separate from 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 the risk of cross channel interference and features both 3.5mm and 6.35mm terminations for use with a wide range of audio equipment.

Refined, mouldable ear hooks
Perfect fit
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.
