Long story short. I owned the Senn HD650 for a while and was looking for a more clear sound. Went through a few phones and ended up with the Grado PS500 last week. These things are amazing and a keeper. I returned the Senn's to Amazon and purchased the Hifiman HE-400. Got them today and they don't sound good to me. Tried them through different sources as well. The Bellari amp drives them well. To me they are much more clear then the Senn HD650. Not as exciting as the Grado's. In fact the Grado's are more clear and have better bass impact... These HE-400's almost sound too thin. The mids seem very recessed which may have something to do with it.. Just don't know about these..Not a good sound to me.
Anyone else not care for these headphones out there?
Would the HE-500 be a better sound. Better mids and fuller sound?
I think i will send them back and get my Grail headphone. Beyerdynamic T1's
