Superlux HD668B Headphones
About this deal
Mids-wise, the HD681F is an improvement to the HD668B. They're slightly more forward, perfect now actually if not for the slightly far-reaching highs overpowering the mids a little. In the end, I feel that the battle mids-wise ends in a draw...

V shaped sound signature but sounds well balanced with bass notes not bleeding into other frequencies. TV/"Home theatre" Setup: Sony Bravia KDL42w653a (calibrated with Spyder4Pro and HCFR) -> miniDSP 2x4 -> JBL 308P Mkii Speakers (2-channel) & SVS SB-1000 Pro SubwooferThe DT990 Pro is more heavily V-shaped, with more accentuation in the treble. The Superlux HD668B has just a little more weight in the mid and sub-bass areas. Both share a similar width in the soundstage but the DT990 Pro has more depth and roundness to its stage. I also agree with what you said in sound, price-performance ratio, and yes the clamp can be a little too strong. The MS1 (especially the MS1i), is quite special, and again, though not that far ahead the HD668B, I would still rank it above the HD668B.

Link to my review and measurement index thread where one can also find a full review overview, more information about myself as well as my general-ish audio and review manifesto: https://www.head-fi.org/threads/956208/ The headband size is self-adjusting but the comfort or pressure distribution aren't great due to the split design. I have owned a pair of Hifiman He-350, that I'd - before owning the 668 B's - describe as being bright. HD668 B is, however, even brighter, and a bit more aggressive.and now this headphone produce sound just like what its hype about..i don’t know why, but maybe i will leave my hp on with the music till morning..hopes it will gets a better peformance..time to sleep..sbelum plng ke desa..
