Interesting..I had an exactly opposite experience...I owned the MS1 and M50 at the same time..No match...The M50 had a refinement, a definition in the highs that the Ms1 could only dream of. The Ms1 sounded grainy and cheap to me. Jazz on the Ms1? No way. I listen to 80% jazz on vinyl and flac. I preferred jazz piano and saxophone on the M50 by miles. The MS1 were sold shortly thereafter. My worst headphone purchase ever..
The M50s are great, but I somewhat still prefer my Alessandro MS1i.
The MS1is can really get the highs and mids bursting out with life! It's just amazing. Whereas the M50s, it's kind of covered up. I just did a short test to a J-Rock song, and when I was listening to the song with the M50s I had this feeling, when the highs are suppose to hit this certain level, it just doesn't with the M50s. It's as if someone is teasing with you, you jump up to grab an object off a persons hand, and you're nearly there, sooo close to grabbing it, and then the person who is teasing you moves their hands up higher and you don't get the object. Yeah, it's like that. You get hyped for something but it doesn't come. Yeah, that's the feeling I got when I was comparing the MS1i's to the M50's with Highs/Mids.
The bass is a definite win on the M50's. Strong and thumping, great for electronica music, no doubt. The MS1i's has a decent bass to it, which I don't mind for rock, jazz and classical.
Rock, Jazz and Classical has to be the MS1's.
Electronic, R&B and Pop is to be handed to the M50's.
