We have contacted our vendor and unfortunately, Sennheiser is not offering any more drops for the rest of the year. We'll update you if anything changes.
I own the Momentums, and can vouch for the quality. They are comfortable, stylish and have a great sound. In regards to reports of them being "bassy," I call BS. These are some of the most pure sounding headphones I've ever heard, and boast incredible clarity. I actually prefer to disable my equalizer that I would normally have running, as I feel the Momentums do a fantastic job of giving me a well balanced sound. Granted, I'm no audiophile. My $.02, hope it helps those on the edge!
I'd LOVE to see the Momentum over-ears. The on-ears keep showing up here, but I'm definitely interested in the overs. Want 'em in ivory to match my HD598's.
I listened to the Momentum and I actually quite liked them. People say they're a bassy headphone and I don't agree with that. They're closer to warm, if anything. You might have been disappointed by a slight lack of treble energy, assuming you've listened to them.
