I have these and I personally like them. Not only because of the sound quality, but the experience of owning it - the lovely case with a subtle embedded Sennheiser logo, the machined aluminum plug and remote,the leather band and pads... and when those pads go on your ears, you get great sound, too. These are my first "good" headphones, so I'm quite happy with them. And they're $220 on Amazon, quite a bit lower than the $350 list price.
Same here, for me, they are an excellent buy for that overal experience you receive for the momentum's!
I've said it before and I'll say it again, I won't be parting with my momentum's!
