RHA CL750 is harsh out of the box, but it becomes a great headphone once a simple EQ tweak tames the treble.

Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about RHA CL750

  • Exceptional build quality with 303F stainless steel housings
  • Stellar clarity and high-frequency detail retrieval
  • Generous accessory bundle including 12 pairs of ear tips and a carrying case
  • Durable, high-quality braided Oxygen Free Copper (OFC) cable
  • Comfortable Aerophonic design with moldable over-ear hooks
  • Excellent 3-year manufacturer warranty
  • Rich and accurate low-end response when properly powered

What customers don't like about RHA CL750

  • High impedance (150 Ohms) makes them difficult to drive without a dedicated amplifier
  • Treble can be overly bright, sharp, or sibilant on certain recordings
  • Cable is hard-wired and not user-replaceable
  • Lacks an inline remote and microphone for mobile use
  • Soundstage is often described as average or intimate rather than expansive
  • Recessed upper midrange can sometimes make vocals feel distant

Verdict

The RHA CL750 is a high-resolution, precision in-ear monitor featuring an ultra-wideband CL Dynamic transducer housed in 303F grade stainless steel Aerophonic enclosures. It delivers a bright, articulate sound signature with an impressive frequency response of 16Hz to 45,000Hz, balanced by a 150-ohm impedance and 89dB sensitivity that primarily targets use with dedicated headphone amplifiers or high-powered DAPs. Main characteristics include its stellar industrial build quality, a 1.35m braided oxygen-free copper (OFC) cable, and an extensive accessory package with 11 pairs of ear tips. Its primary pros are exceptional clarity, durable materials, and a comfortable over-ear fit, though it suffers from being notoriously difficult to drive without an external amp and having a treble-forward profile that some users may find too sharp or peaky.
