At the moment I am stealing the Apple Stores wi-fi
A good reason for that though, they have the Sennheiser Momentums in there..
Well I plugged into my own source and started listening to some material. I listened to some acoustic, trance, classical and more electronic stuff like Phaeleh, etc.
Interesting... straight away, vocals in the midrange was a lot more in your face and slightly clearer. What they did lack though, especially when listening to the Mahler track I have, they lack detail in the upper ranges...
Also... not as much bass detail either... only ever so slightly.
One other big aspect I noticed was the soundstage in width on the M-100s are ALOT better. The sound goes much more left to right with better placement.
If anything, that makes the M-100s stand out the most.
So... apart from the midrange clarity, the M-100s have them beat.
They also had the Amperors in there... but I'm meant to br clothes shopping, and the girl I'm with is getting a bit stressy
Interesting though. Oh and the Momentums weren't as tight on my head and were more comfortable. The M-100s also go louder on my S3. I had to pretty much have the volume on full to get the same volumr as 3/4 on the M-100.
Anyway, that is my assumptons for now. Must dash!
