Beg to differ with my subjective opinion... balanced - HD-662F, best sounding - HD-681 with filter mod.

Never heard HD662F but what I have read it seems good for closed back and low budget. I would want to fully agree with you but I haven't heard HD662F. Modded HD681 is very good but lacks a bit airiness and nuances, sound quality is very good.

btw is it just me or doesn't the hd681 and akg k240 look the same?

anyone opened the 2 and looked at the drivers?

 

[CoiL]

wigglepuff, everybody knows that LOL. They have different drivers.

LOL it would have been a mess if they both had the same driver, which would have made every headphone related forum lively.

 

[wigglepuff]

anyone has the hd669? how the treble on it? do you have to mod the drivers like the 688b to reduce the sharpness of it?

 

[CoiL]

wigglepuff, You are mixing things up, 668B does not need any mods, it`s the 681/662 series that need to be filter-modded.

 

[wigglepuff]

oh you're right, i was reading this article and the last one with the sock was the 668b lol

669 should also have sharp treble. But I personally think that all those foam and dampening mods are too much hassle.
Just take one of Fran`s hardware filter mods and You`ll be good. Love how my HD-681 sounds with mkII mod and exchanged dual-entry cable.

 

[wigglepuff]

oh the reason i like the 669 is its the only thing that would probably fit my head, my X1 which is already big fits perfectly to maximum extension. so anything smaller than the X1 wont fit my head. 47cm ear lobe to ear lobe, round shape (and this is with flatcut hair, if I have chunky hair, then nevermind)
 
unless they are designed to have so much extension like audio techincas ws55x and philips shl3300 or mdr 1r's which can extend so much with the extension arm design, anything smaller than the X1 just wont fit my head.

You can do hw filter mod also to HD-669 or HD-662F. I made filter with custom values to my HD-662F and it turned them into very flat and clear sounding studio monitoring cans. Good for oldschool rock listening also.

 

[wigglepuff]

yeah I probably will, and I listen to a lot of metal and rock. the 661 are 7506 clones? or diff drivers? or maybe production rights with minor change like they do with tanks.

 

[CoiL]

Only some Samson should use same drivers as superlux but I`m not sure. They shouldn`t be clones of 7506 as far as I know. Stop looking consolation from being clones with some cans... just mod them and enjoy!

Waiting the arrival of my HD 681
Since I won't be making the mod, I want to know how I should set up the EQ to reduce the highs/treble problems. And how good does get compared to do mod?
 
I use the SBX Studio Pro with onboard sound card
Sorry cuz I dont have the permission to use images so I will just put a link for an SBX Studio Pro example:

[wigglepuff]

some say the late production batches of the hd 681 dont need modding? or was that the evo? try it out first before trying to mod it. you can probably just eq it a bit to lower the db levels on the highs, wont be a major problem there I think.
