Masya's have had 35-40 hours burn in now. I'm also using a combination of thin foam (similar to monk) and a heigi donut. This, to me, is the best combination so far. Still waiting for my VE ex pack to make a monk thin and monk thin donut (cut into donut) combo, which I think will be my best bet.
My opinion of them is pretty good. Excellent for some tastes, not so much mine.
- Very pleasing soundstage, imaging and extension. This is the best part about them. Gets close to headphone territory here. Soundstage is big enough for earbud standards, imaging seems pretty accurate, extension is impressive on both ends! 9.5/10
- Quiet bright sounding, but the smoothness of the upper mids makes it a tolerable brightness.
- Sub bass is well controlled. Almost reigned in and not reaching its full power. This is intentional though as to keep the low end clean and completely bloat free. Personally I'd prefer slightly more emphasis on the sub bass for a more impactful bass experience. 8/10
-Mid bass is lightning quick, almost too quick which means it doesn't flow into the lower mids, on the plus side there's absolutely zero congestion. It's over before it begins on some tracks whilst being very powerful at the same time... it's very tightly controlled, holds some impact and just about delivers enough thump on most tracks. 8.5/10
- Mids and upper mids are the strong point of this earbud. Near perfection if you consider neutral-bright sound as a good starting point. So much detailed clarity, smoothness and control in delivering vocals and acoustical instruments. Only downside is it's not quiet as full sounding as I'd like which is the sacrifice made with such clarity and it's neutral and bright sound. 9.5/10
-High's and treble carry on where the mids left off. The whole transition between mids and highs is exceptionally fluid. There's incredible detail and extension here, but it's more analytical in its presentation thus lacking some sparkle. Also whilst being smooth for such a bright earbud, it can occasionally lose control on some tracks so it's not for sensitive ears. Overall almost as top quality as the mids. 9/10
Personally I don't feel it's the complete package for my taste. It's lacking the full thick vocals, sparkly highs and some sub bass rumble to be my end game earbud.
Although I can see some people loving what the Masya has to offer. Clarity in a well rounded and neutral-bright sounding earbud.
