Headphones

Hello,

I have been checking for some time to up my headphone game to the HD series (I currently own an HD599). Now there is a 30% discount that I found for HD660S2 which makes it around 450$. To make a comparison, HD600 V2 can be bought for the same price as well. It can go around -10$ for V1 too.

So my question is; is it worth it? There are 2 aspects for this question though, one is the worth considering the price and the other is the worth considering the sound signature; how it fits my taste. For this second aspect, I will try to explain the profile I like and hopefully you experienced people can help me out in my search.

As I said, I use HD599 as an open-back, use the oratory EQ for it and a little additional decrease for upper mid to lower treble range (I am sensitive to high treble so even this warm headphone can cause disturbance for some songs). Additionally, I have a Focal Bathys which I use for commute, travel etc. There is not much needed for this headphone to me. I just increase the mid range a little. As a side note, I started to thing these Focals are on par, if not better than HD599, am I going crazy?

Anyways, so as you see I like warmer headphones with crystal clear mids. High treble is a pain for me, I tried Sony WH-XM5's and had to return it. Not just because of the treble but that's another discussion. For the bass, I don't have much experience of high quality bass although I tried Momentum 4's and for me their bass was spectacular. Probably the best I've heard in a headphone. I would love a deep bass but I wouldn't want it to be muddy which would mask the lower mids.

So do you think HD660S2 is a good choice for me? Thanks in advance
