I did this mod tonight and will post impressions later. Right now I'm really impressed. The bass is even better on my Q701 now than the Annie ever was.
So far I haven't really heard anything else different in the sound signature..how is that even possible?
My ears are really bombarded now due to spending about 5 hours today on modding things and listening to music.
Strangely with the extra bass impact the sound is even clearer?!
NOTE: This mod is very dangerous if you don't know how to solder if you pull apart a wire. You have the mini-XLR plug just hanging there.
It was a pain to remove this piece without tweezers and without removing that inside bracket. Luckily this just peels off.
It was actually more of a pain than recabling my HD-598
I wonder if the K712 and Annie have the bass port open? On my Q701 it was closed (Well, duh). Some have said it's open, but it definitely isn't.
It'd be hilarious if the K712 bass port was open.
Just checked and my K702.65AE have the cover over the port. You can kind of see in from the side with the grill off without removing the soldered wires.
