I purchased these today at a local retailer. Being a bit of a fanboy, I decided I wanted these even though I already own the QC25. I have only been listening to them for less than an hour, but I am very impressed. The soundstage is the thing that keeps wowing me. The separation and placement of instruments is really good. The comfort is supreme and the bluetooth paired very easily to my iPhone 6 plus. The QC35 arrived with 70% power out of the box. After almost an hour, they are still at 68%.
Sound impressions:
I always start with Thievery Corporation - A warning (Dub) from Sounds from the Thievery Hi-Fi album. This is about the deepest bass of any track I own. The QC35 handled it easily. Very deep and without driver rattle and still able to reproduce the midrange and treble. The rhythms in this song like to oscillate back and forth and that staccato effect is reproduced very well.
Next up was Steely Dan - Everything Must go. I started with Green Book as it has a very prominent piano (always the most difficult instrument to reproduce) and a "Lead Drum" pushing the song forward. This song also has a wide soundstage and, again, wow. I moved on to the Title track 'Everything Must Go." The song open with a cacophony of instruments all improvising with a rolling drum adding backbeat. On the QC25, every instrument can be picked out. The sax is wonderful and seductive.
Moving on, I played The Toadies "Possum Kingdom" to see if the grungy rhythm guitar could be reproduced. Sorry, but I got lost in this song and forgot I was reviewing. That is always the mark of a great headphone to me.
When I regained my senses, I played Sublime "Garden Grove" to see if the impact from the steel drum would show up. It did, easily.
Moving on, The Stone Roses "Love Spreads" was up next. Lots of chances to muddy up on this one - bass and lead play together with a heavy drum set. Nope, the QC35 handled and kept everything in it's place.
Oh, the noise cancellation. Come on...Bose owns here. Literally, they take legal action against any company that attempts to infringe on their noise cancelling algorithm. Even Bose detractors admit that they own the NC segment.
Should you buy the QC35? If you own no other NC headphones, it's a no-brainer. Get these today. If you want to cut the cord and have the best noise cancelling money can buy, get these today. If you are completely insane (like me), and already own the QC25 - well, your call on that one. You could probably purchase a bTunes add on for a lot less.
