Have any of you folks had experience with the MDR-1RBTs? I've been looking for a pair of $300-$400 headphones to replace my old set of Grados, and I just can't decide between them and the Momentums. On the one hand, a lot of people are saying that the Momentums have better sound quality. On the other hand, many others seem to prefer the MDR-1Rs (perhaps qualified with the sale price?), and they're also universally considered the more comfortable of the two. What complicates matters is that the 1RBTs have slightly different hardware and reportedly sound a bit different from the 1Rs. Unfortunately, most measurements and reviews I've been able to find focus the phones in wireless mode, which I'll only be using half the time and not for audiophile purposes. The Head-Fi 2012 Holiday Gift Guide says that "with sound quality in the MDR-1RBT's passive mode even closer to its passive-only MDR-1R sibling, it's obvious Sony spent as much time and effort getting the MDR-1RBT acoustically tuned as they did perfecting its electronics", but that's a very non-specific statement, and worryingly implies that the 1RBTs sound worse than the 1Rs in passive mode.
I've done a bit of listening with both, and keeping in mind that this is my very first experience with $100+ headphones, it seemed to me like the Sonys had a wider soundstage and the Sennheisers had better detail. (But for all I know this could be BS. It's hard to compare sound if your listening happens a day apart.) Neither headphone jumped out at me as phenomenally better than the other.
I'm specifically interested in all-around performance, as these will be my main audio output for pretty much everything I do.
