The sound expertise of Sennheiser with an eye catching design?
Yes please.
 
The Sennheiser Momentum delivers in many areas.  There are plenty of other reviews from people with better trained ears than mine to read about the sound.  That said, I'm very pleased with the sound quality.  The build quality is outstanding also.  It's refined and the only set of headphones I own that I consider a work of art.
 
There are little issues one can note.  The cozy fit is usually fine for my ears, but not always.  It's a bit too snug and it wears on my ears after a couple of hours.  As a set designed for portable use, I do wish it had some mechanism in place to make them more compact.  And while I do feel I got my money's worth with this purchase, I don't feel like I got an especially good deal.  I got what I paid for.
 
Highly recommended.
