i've always wanted to try these too....john franks of chord uses this model i believe
(see link to interview with him below))...these were just revised a yr or so ago, too.

'''HFN: What is your personal favourite headphone? earphone? DAP?
John Franks: Personally, I like the Sennheiser HD800s, they pair well with Mojo, Hugo 2 and my tastes.
My favourite IEM is the Ultimate Ears Reference Remastered. ''
