[EX Q]: We bought two of these.This product. Does not fit 128 disk. The folders are so tight against the edge once you start filling it. It becomes impossible to out disk in towards the back of the case. Will be looking for somwthing decent.
[EX A]: negative

[EX Q]: Do not replace your Bose headphones. Get these replacement pieces, throw the stock ones away. These will make your headphones sound the way you hoped they'd sound when you got them. I went for a 20 mile bike ride with them stock and when I got home I checked the mail. My replacement (nibs?) were delivered. I put the new ones on and threw out the old ones. The sound is incredible. Get them. Even if you aren't sick of the stock nibs. Get these. You won't be sorry.
[EX A]: positive

[EX Q]: It loses calibration after a couple times of opening & closing the blinds. I've had it for about 2 weeks & have been recalibrating all 3 of them every other day. It's nice to have them on schedule mode but they're always uneven & it's annoying to calibrate again & again.
[EX A]:
negative
