I was impressed by the M500 but got it as a curiosity - I don’t have room for an on ear portable headphone in my schedule. But I do use IEMs at work and outside a bit. So I ordered the M200 yesterday. I’m currently using the Sennheiser IE800 a lot. I don’t know if the M200 will “beat” it but if it’s close enough, it might be a “good enough” replacement. I like what I’m reading about a nice, full sound without having a bloated bass. I might not get them for 2 or 3 weeks, though (slow shipping, bah). Anyway, I’ll be reading more impressions in this thread while I wait. Looking forward to giving my own down the line.
