Using the supplied Bluetooth cable, there is a slight hint of compression in the upper mids, but using the 3.5mm or 2.5 mm cable reveals this hiccup to be a minor fault of the Bluetooth technology. The CL2 forward mids stretches the staging from front to back but that lower- mids dip takes a little bit of clarity and separation out of the mix for me. All sound great because the complexity or focus of the tracks did not trip up the FR of the CL2. The CL2 may not have the same level of treble extension or sparkle but that’s a wise move given how much amplitude is in those upper mids. Thus, I would shy away from calling this a generalist tuning. Noise is not an issue on these two monitors with a quiet background on all DAPs tested, neither are terribly sensitive for that matter. Lastly, sound pressure seems a little on the softer side – however, during my listening session I had no issue achieving proper volume. For my review, I was handed a fresh unit with no prior playtime whatsoever. Why oh why would you review this IEM with foam tips. Beyond that, the CL2 drops a fair bit into the lower-mids and stays relatively recessed until about the 1K marker. RHA. Two incredibly different propositions here.

Second, the iSINE 10 uses a much bigger full-range 30mm planar driver with Fluxor magnet technology and a patented Uniforce voice-coil. The RHA CL2 comes with one more cable and it is their aptX cable wireless BT detachable design and I suspect the one you tend to see on their wireless models such as the MA750 Wireless edition. Slightly bright, this part of the frequency range remains well-tempered, and never becomes too harsh or uncomfortable. Just you and the music. This is a larger monitor compared to the CL2 by some distance and an open back design. The ME.1 is rated at 23.1 ohms and 109dB compared to the CL2’s 15Ω and 89dB SPL. Less warmth, more power, and a strong upper mids focus. For example, the Cayin N6ii with the A01 motherboard was an excellent compromise between a natural sounding timbre and good power. The iSINE 10 follows a fairly typical Audeze tuning with a flattish but punchy low-end and a gentle but linear rise through the lower-mids and peaking at 1-2k. It is somewhat niche and bucks some previously accepted notions of how a planar magnetic driver could or should be tuned. Every tone appears accurate, with plenty of contrast for a truly articulate sound. After a week (and a couple extra days) it was mailed off the the next reviewer in line.
