I have had a pair of RE0's for more than 3 years and I love them to bits. Well defined bass, albeit a bit subdued, great voices and sparkling, pristine treble without any spike or sibilance (quite a feat).
I want an open headphone that sounds like the RE0 but with a wider soundstage than the IEM.
I had a pair of Q701s and sold them due to the treble spike and for being a bit thin sounding. I tried the HD650 (old black silk version) and I find them almost muddy from being so veiled. I even A/B'd the Q701 and the HD650 and it was like someone was putting pillows between my ears and the HD650 capsules.
My HD650 are now for sale and I would like to give it another try at finding - that - open headphone. My gut tells me to go the HD600 route. More neutral, less mid bass hump, more highs while maintaining the typical Sennheiser smoothness (the RE0 are very smooth for me). Or maybe even the HD598? I'm not a basshead by any means as you would have guessed from my adoration for the RE0s.
I find Grados too in-my-face and sibilant.
What do you say? Closed cans are out of the question. Never heard a pair that I liked.
I am beginning to think that I might as well keep only the RE0 for all my private music listening needs. And that reminds me that I don't know what to buy these days that sound like the RE0 when my pair fails.
