With the AD700x, I find that the highs can be a bit too tinny and vocals sound a bit more muddy, but the bass is quite clear as opposed to being strong

They bleed a tiny bit through but even in a fairly quiet office, apparently it's not enough to hear across the cube.

Excellent for positional audio, just the wing headband is a bit loose.

Comfortable but a bit loose fitting.

I was worried a bit that I might hate

If you are looking for something that DOES have replaceable cables, the MH50X's do, but they are a bit less comfortable.

Comfy and durable no real complaints except the wire is perma bent and it bothers me a bit

It feels open, and freeThe noise leakage isn't as bad as I thoughtThe comfort is outstanding

To correct I have one of my wife's hair elastics that I put around both pads problem solved

Holy s**t, these things are amazing
