Completely subjective, possibly bordering on useless, first impression after 60 minutes with my new XM3s...Dayummmmmm...Based on the preliminary reviews I was expecting an upgrade from the QC25s that I picked up on Prime Day, but for someone that enjoys bass the XM3s really brought the music to life.
I listen primarily to hard rock/heavy metal, but really anything from Metallica/Disturbed to Lionel Richie/Neil Diamond and lots in between. I listened to a tune or 2 from each of those artists and a few others and I can't count the number of times I said "wow, that's impressive" with a big perma-grin. That was with ANC all the way up and EQ off.
When I tried the QC25s for the first time, I was very impressed with the ANC and comfort. They were my first experience with ANC headphones, other than trying them in the store. I listened to a few songs, but did not get any emotional attachment like with the XM3s. The first thing I did was try to find an EQ app that I could use on my iPhone for not only locally stored music, but apps like Pandora, Spotify, etc. with no luck. I've pretty much only been using them to eliminate background noise with no audio source since I got them.
In contrast, on the XM3s you have full control to tailor things to your own needs via the Sony app and the various NC, EQ and other settings. For me personally, the XM3 experience out of the box is nothing short of amazing compared to the QC25s.
I jumped on here to leave a quick impression and to pull down some more songs I haven't heard in years, to see how they will sound on the new headphones. So far comfort is excellent, ANC seems slightly better and the sound quality is no comparison.
If anyone has any specific questions, let me know. I appreciate all the help you guys provided previous to my purchase decision and wanted to say thanks!
