They seem indeed the same analog basis, different default dsp eq thoughAssuming Moondrop data is actual measurements, RAY and MAY are indeed the same IEMs, with a different shell. This also means RAYS should be perfectly usable as a general purpose IEM, like MAY (MAY is actually a pretty good IEM IMHO...) and the gaming credentials--low latency, noise-cancelling mic.--are just extras.
