HD 6XX
This is pretty awesome sauce, why for a few reasons. I will explain a bit of my headphone Journey first.
I have had two or three moments where I felt like I hit a real sweet spot of content with headphone listening. One of the most memorable times was when I finally got the Bottlehead Crack and Speedball amp and plugged my unmodded pair of 650's in. I was in heaven for a bit. Such wonderful tonality, musicality, and my music simply sounded correct or as the 'artist intended. I have had about 6 pairs of HD650's with this HD 6XX being my 7th. The 6th pair I bought modded but completed the mods on it myself and now am enjoying tighter bass with more slam, and a more open and clear sound. Fast forward and I am hearing this little old timer scale like madd on more expensive gear.
People complain when I use the HD650 as my reference headphone for reviewing gear or comparing them tonally to other headphones but I would wager a bet that if you took a consensus as to which headphone hit the mark most tonally, the 650 and 600 would easily.... easily come out on top. So much so that many of us to this day wonder why no other company has managed to make that super HD650.
Modding
The HD6XX is awesome sauce because you can now buy one at an affordable price and mod the crap out of it... Heck for the price of one brand new HD650 you can buy two HD6XX and compare modded to stock and practically make your own SUPER HD650.
There are tons of resources out there that can show you how to mod these and let me tell you... It is very easy. With all of the other pairs I had, I was scared to open them up and mod them and it wasn't up until a recent meet that I got to hear what a correctly modded 650 sounded like and knew from then that I needed to end my buying and selling of these suckers and hone in on getting it to sound like how I wanted to.
HD6XX compared to my modded pair:
I simply now have a more open pair with much better bass slam (you know me
) cleaner, and richer mids, with a more open sound.
I cant wait to see measurements of the HD6XX compared to stock to see if there is anything funk Sennhieser has done.
