I've just received a pair of Momentum's that I bought second hand here in the UK......Approximately 3 months old and in excellent condition. I bought these following the recent sale of my Beyerdynamic T70p and I must say the Momentum's blow the T70p Waaaaaay out of the water!!! I wish that I had bought the momentum 12 months ago instead of the T70p's.
Waaay more controlled and solid bass, nice sparkly highs (but not bright or fatiguing) and oh soooo smoth mids :-) For the money these have got to be one of the best in class headphones your money can buy.
They sound excellent directly out of my DX50 but soundstage and dynamics improve tremendously with the DX50 connected to the "Line In" of my O2 amplifier as a desktop solution. My iPhone and iPad also drive them with authority without problems.
I have the Over Ear ones...and I must say I would definately not class them as over ears (well unless you are a 10 year old with exceedingly small ears). That said they do fit although not completely over my ears and are very comfortable.
As I type this I am listening to the "Pure Heroine" album by Lorde and I'm really impressed......Vocals are clear and smooth and the bass is impactfull and has authority. Of course these aren't as good as my £600 Dream Earz Customs...but hell I wouldnt expect them to be
