I don't think fjrabon was saying that HE400i would be better than HE560 - I interpreted it differently than that. He was responding to post #2952 which later reeltime corrected his typo of HE650 to what was intended as HD650. The original post meant to say one fella prefers Senn HD650 (mistyped as HE) and HiFiMan HE400 over TH-X00, for the price. In post #2957 the other fella conversed the 400i version is better then the TH-X00 in context from the two conversations. He compares 400i to "...premium...on a closed headphone". That's how I read it. First fella reposted in #2963 he made typo and meant to say HD650, not HE650 as originally typed (and led us to maybe all think HiFiMan HE560 accidentally).
Have HE400i, HD650 and TH-X00, and agree with both fellows for the price, the 650 and 400i outperform the Fostex. With note comparison is different open vs closed. Am happy with all 3, and like the 3. Needed a fun lifestyle basshead type for my collection, and the wood cups are nice. Fan of biocellulose, especially prefer Sony's vectran based substrate over other and newer microfiber processes. Previously posted the CD3000 outperform these Fostex (Sony is more refined among other things).
Agree the HiFiMan HE560 at current $689 price is a great buy, like asabides writes. So, I agree with all 3 guys, just want to keep a backseat to it all, and wrote how I read that context mix-up. Change is Good just posted about the same context impression as I typed this.
