caused a loud audible popping noise to occur that temporarily centered the soundstage perfectly!

Poor noise isolation

You can also hum 'Danger Zone' by Kenny Loggins to get better noise isolation

Poor noise isolation

Sony has noise cancelling that does not suck, i.e drowns out most noise and does not wreck the music in the process

Just like any bluetooth headphones, there's a very faint pink noise on wireless

When charging and using, it generates weird noise

The passive noise cancellation is perfectly adequate at home, but when flying on a plane or commuting on a bus or train, the listener really needs active noise cancellation.

Even though the manufacturer claims "2) Passive Noise Isolation - Naturally cut the distractions of jet engines and unwanted noise without the hiss and pressure of Active Noise Canceling (ANC)

Just like any bluetooth headphones, there's a very faint pink noise on wireless

There was absolutely no difference in the sound of jet engines with music playing or without."PASSIVE NOISE

Decent bass impacts, breathy vocals, lots of fun noise - the Wireless2 plays this perfectly

....there are too much static noise on the background i can hardly concentrate

These are definitely Hi-Res sound and also have a noise-isolating feature that really helps to immerse yourself into what you’re listening to.

"Passive" noise cancellation is just a factor of these things cover your ears like any other over ear headphone.

With that being said they sound great, however the battery is only decent, the headphones have very poor noise isolation & I find these headphones lack bass, yet many reviewers mentioned that the bass was overwhelming.
