If you’re looking for a balanced natural IEM with great clarity and transparency that doesn’t compromise on bass, RHA CL2 is very natural sounding and engaging, then you might have found just the right IEM for you. If you’re keen on treble sparkle and/or sensitive to upper mids you should make sure this won’t be a blocker for you as its lower treble are tuned conservatively while upper mids are more daring. If you use the CL2 mainly on the move with the neckband, this shouldn’t be an issue.
