Note that I have the well regarded Sony 1000x wireless ANC headphones sitting right here to compare with the PX

Fantastic sub-bass, adjustable ANC (must for me because too much makes me sick), and just outstanding imaging

I've tried both the Studio3 and the PX on long flights, and found their ANC to be about equally effective

If you need only the best ANC, you should probably look elsewhere

Yes the ANC is amazing , but it is almost like you don’t need it

The ANC is adequate for all environments albeit not as good as Sony or Bose, comfort is

This causes me to break out of my relaxation and readjust the headphones which is something that does not happen with my other top ANC headphones

The ANC is amazing as well, but I found that with the amazing sound and snug fit of the headphones makes it almost an after thought

I'm returning them because I have to position them a certain way and use my hands to clamp down on my ears to get a really great ANC experience

29 hours with Bluetooth and ANC disabled

Like other reviews have stated, if you are looking for industry best ANC, look at the 1000xM2 or QC35.The

Both paired up perfectly and both worked exactly as they should have.

When I got the headphones, I was confused as to why music sounded so distant and faint through them

I've owned the P5 and P7 as well as the B&O H8 and H9 as well as some Bose cans
