But if you want bigger impact of bass and better sound isolation - M-100 is the way to go, but don't expect clear/crisp sound in those since mids are recessed and overshadowed by bass quantity. Look up Tyll's frequency response data for M-100 and M-80 on InnerFidelity, you will clearly see a wide cut in upper mids of M-100, while with M-80 the cut is much narrower and XS will be similar with a better treble extension. But at the same time, on-ear headphone fitment is always a matter of personal preference. They might sound great, but won't fit you the same way they fit me. Wonder if you are ordering brand new from Amazon, just get both and keep the one which you like. Otherwise, if you are buying a used M-100, buy XS and see how you like the fitment. I'm pretty sure you gonna like it's sound, just need to try these on. Or how about this, Apple stores should be carrying M-100 and soon XS. Maybe you can demo it in the store? Brookstone also carries M-100 in the store.
I'm starting to think the XS is more of the way to go. As for fitment, I did put on a pair of on ear headphones at Best Buy to see what they are like, (Monster DNA) they weren't bad, but they weren't quite as comfortable as over ears. But portability is still an issue for me, and wearing the headphones around my neck would be a common thing, which is where the XS would succeed at. But I did have a pair of LP2's a while ago and those were pretty comfortable, except the shape of the ear cushions was weird for my ears because I have big ear lobes. So maybe the XS would be overall more comfortable for me.
Since the XS has a better overall sound, I'm just wondering, is there enough bass for my taste. Like, for bassier songs, would the bass be prominent enough, or would it be more in the background?
As for the buy both option and return the one I don't like as much, that is definitely a possibility. My nearest Apple store is about half an hour drive from me. I suppose I could make the trip this weekend since I have 3 days of school this week, but I don't even know if they would have either of the headphones to demo.
