Hmm… that sounds like the Yamaha EPH-100 to me. Great bass with good depth, very good isolation for a dynamic-driver earphone, and the build is pretty solid.
Thanks for the reply joker. I thought the EPH100 seemed like the best option as well. My only concern was the size of the nozzle. I use the small tips on the SHE3580, so do you think I would have fit/comfort issues?
