I was comparing HD600 and HD650 frequency response here, and wondering if it is worth to call Senn and spend 130$ on 600 drivers. I put them in my HD650... but HD600 looks less linear, technically less refined... hence less resolution on treble?

Hmm I don't know if it is worth to pay another 130$ ... Hell, I want more quicker bass then HD650, probably less prominent, but I am worrying it could sound very close to HD598, similar slight glare effect on treble not as full sounding but more ,,alive''... that you folks think?

I think HD650 is pretty decent performer and reproduces fullness of string instruments, while on HD598 you have some grain not as bad but noticeable. Right now I am listening Vivaldi's Musica per Mandolino e liuto, and it sounds very rich

but when bass comes into play I am less happy, using Ibasso D12 now with changed op-amps

I am reluctant to pay 130$ for HD600 drivers, but if it is better I have to :D

These from the SD meet. These were pretty beat up. The pads were pretty worn and the drivers were exposed with the lining hanging loose. However, the owner was fairly fond of them and said he would often fall asleep with them on.

FR comparo with HD600 from the meet (blue right driver), and CT's HD600 (yellow right driver)

These look fantastic except for that imbalance and wobble in the left (which might be the exposed driver lining?)

Do you think there may be an acoustic leak from the jack hole? ~Tyll Hertsens

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin

Maybe. I remember I measured it twice with the same wobble result. I even removed some lining that was touching one of the drivers. It was a little beat up.

I must agree with the owner when the frequency response is that linear. For a beat up headphone that is simply good.

Or perhaps pads worn out in a different way. It'd be interesting to see measurements on the same set with fresh pads.
