No, the XM4s are regarded the best overall by many even with the newer XM5, never had a "white Noise", I would go for the XM4s, the XM5s was barely any update apart from a smaller form factor.
Yeah I have the Sony's XM4s and they last 9-10hrs without ANC.. Apparently the XM5s are a downgrade in the SQ area so Ive read...... I have the Technics AZ80s also and they do have about the same battery life as the XM4s, not as good in SQ though. But when swapping for the Sonys after listerning to the Technics, its not a huge difference by anymeans as I not like "wow the sound of these Sony's are so much better" but the Sony's have a lot more base despite the Technics having larger drivers
Since getting the Technics just under 2yrs ago, I have used the Sony's only a handfull of times as the SQ isnt good enough for me to fight with getting them in my ears etc

.... So the Technics are a alround winner for me...
Ah yeah the ANC are rubbish with the Technics, but I never use the ANC as the buds/tips do a great job at blocking the outside noise anyway..... But but the "Ambient Noise" on the Technics are much better as there no or scratching/whitenoise sounds like you get with the Sony's when its turned on. Also the ambient noise keeps cutting out on the Sony's with loud or high pitch sounds where the Techincs dont. Plus the Technics automatically changes the level of the ambient acording to the wind, but that is a bit annoying when your having a conversation with someone and you get a gust of wind, as the ambient gets basically turned off and takes a few secs for it to automacally adjust again.
Atm the Technins are about £150 instead of £210+
Technics AZ100 are meant to be very good. Had my eyes on them myself.
I was thinking of upgrading mind to the AZ100s but apparntly people say its not worth the upgrade...... Plus for me its only really a bass boost that the 80s needs and yeah the bass is better on the 100s but not by a huge amount, with what people say,, so I'll stick with the AZ80s as there perfect in every other way... Great battery life, they snap in your ears like magnets and dont come out, and easy to take out of the case. Plus with being such a comfy fit you kind of forget that your wearing them as they dont hurt your ears etc,, even after 4+hrs use. And theres a gaming/video/movie mode where everything is in-sync when turn on.
