Got my HD681 today.I found that the the HD681 has laid back sound signature compared to HD688B which is flat.Definitely has less detail but I can enjoy the songs more with HD681 now

getting really impatient now for my cans to arrive.. huhuhu

Are you using a headphone amp to drive?
HD681 is far from laid back, I found it very forward especially the vocals at at times can be a little 'harsh' on midrange especially on those low bit rate mp3s.
I do not use any headphone amp with it.

Yes it's the HD688B that I want. I am serious Thanks jazzy.

As usual I taken off the foam as well as peeling off the sticker inside.More details coming in now

I'm using Maverick D1 dac/amp with it (changed the stock opamp with the LME49720HA and LM45652HA).I found that the HD668B is very forwarded in mids compared with HD681 (which the reason why I like the HD681 so much right now).You're right about the mids are somewhat "harsh" through,same goes to "HD668B" as well.

One thing for sure I found HD681 to be more comfortable using it compared to HD668B.I still remember the "death" clamp that HD668B has the first time I use it which prevents me of using it more then 1 hour of listening.

Just got 668b. Play some song (flac n mp3)..this is comparison for 3 headphone (akg 240s, beyer dt880 250 ohm n superlux 668b)

240s = erm..kinda muffled n slightly bloated in bass, roll-of in treble..n mellow mids. Soundstage is okay to me (not to forward n not to backward)

880 = high energy in treble...slight recessed in mid..bass is just enough n well textured(dance/hip hop etc type of song..i dont it has that bass punch...basshead lover please go denon or sony extra bass xb500/xb700) . Bigger soundstage than 240s.

668b = kinda "v" equalizer...and almost no soundstage (too forward). Treble is quite harsh...but the it has bass punch..but lacks on textured. Suddenly it remind me on grado sr60/sr80 sound signature.

p/s = this comparison of 0 hours (668b) vs well burn-in headhone. Source audio-gd compass + littleghost dBLite

I wanna get some pads too for my 668b.

Planning to try on hd330 but its abit expensive..

got both of my 668b as well as 681... i prefer 668b better than the 681.. i find that 681 is too harsh to my liking.. both are burned in an clocked the same hours..

but as hitman said before.. the 681 headband are much more comfortable compared to 668b.. i think ill switch out the headbands so that i can enjoy my 668b better..


i think that the dt880 has enough bass punch for me though..
