High impedance in-ear headphones for HiFi audio


RHA's CL750 pairs a CL Dynamic transducer with signature stainless steel housings to deliver high-resolution audio with purity and accuracy.

Introducing the CL750
Contained within the CL750's stainless steel, Aerophonic™ housings, the CL Dynamic ultra-wideband transducer is engineered for control, accuracy and high purity sound reproduction over an extended frequency range.

Precision engineered for high-resolution audio, the CL750 should be paired with headphone amplifiers or high powered DAPs and smartphones.

Ultra-wideband transducer technology
CL Dynamic
The ultra-wideband CL Dynamic transducer is precision engineered for high purity, true-to-life sound reproduction across an extended frequency range. A high flux density voice coil array with annular magnet and 9µ diaphragm allows absolute control over audio reproduction at all frequencies.

Stainless steel, Aerophonic™ design
Made in metal
The CL750 features stainless steel housings in RHA's Aerophonic™ design to transfer sound waves, in phase, from driver to ear without distortion at any volume. Eight times more dense than common thermoplastics, 303F steel ensures durability and longevity in addition to low internal resonance.

High-resolution signal transmission
Advanced Cables
Featuring a braided, high conductivity oxygen-free copper cable, the CL750 is engineered to eliminate cross-channel interference during signal transmission between the source device and transducers. Each OFC cable is coated in durable TPE with stainless steel reinforced cable divide and terminations.

Over-ear cable supports
Stay secure
The CL750 features flexible over-ear hooks designed to hold the headphones in position with the cable running over and behind the ear. The over-ear hooks ensure that the headphone offers a comfortable, secure fit in any ear and optimally positions the transducer housings for effective noise isolation.
