This is contrary to my personal experience so I would recommend people test it for themselves. The Sony to me sound far more balanced compared to the muddy, bass-heavy Bose.
I love the Sonys, with a couple caveats that have been mentioned: hand gestures are a gimmick (sometimes skips a track if you remove your headphones the "wrong" way), default charging cable is too short, and my number 1 pet peeve, the announcer voice (for low battery, changing NC modes) mutes the sound, and those announcements are slooooow, which means you sometimes have to skip back if you miss something you were listening to. All minor annoyances compared to the great experience of using the product, though.
