Well, I dunno, I'm somewhat confused by reading all over the Internet how poor the SQ of Bose stuff is in general including the QC35's - having tested the QC35's and compared them directly with the so-called amazing B&W P7's and the B&O H6 and the Sennheiser PCX550's the bottom line *for me* is that the bass/sub bass on the QC35's leaves all the rest in the dust.
With the right sort of music and a good quality recording the QC35's are downright stunning as far as low end. It is felt and is heard and is very articulate, far more so than the others I have listened to.
I'm sort of angry with Bose as I know they have purposely emphasised the extremes of the frequency band - as I guess they always have to some extent with their hi-fi speakers (901's and that mysterious equaliser box) for decades but now I have experienced the QC35's there is nothing so far that comes close as far as low end reproduction - IMHO...
I'm sure that most headsets on the market have a much more linear frequency response than the boosted one that the QC35's have but boy they are all so boring after listening to my music on *any* of them directly after hearing it on the 35's.
So, I am very sorry to see/hear that I am pretty much the only one who actually likes using my QC35's when NOT flying!
The ANC is brilliant at home too when I want some peace and quiet and to focus on nothing other than music.
BUT! I see that I'm not quiet the 'only one' - here's a review that also speaks good of the QC35's, especially of the bass:

Also, like me, he does find the upper end of the audio band a bit 'uncomfortable' at times - that's my main complaint with the QC35 - they are very unforgiving with poorly recorded stuff where they can make the top-end sound very gritty/steely.
Stay away from that type of recording and they sound mesmerising...
