I can be a bit worried about it... which is part of why I love noise-cancelling earbuds. ;3
I feel like noise cancelling earbuds is a bit of a misnomer.
Incoming autistic info dump, don't take this as an attack on you; but as my general frustration over "noise-cancelling" earbuds.
Active Noise Cancellation (ANC) is a straight up marketing gimmick. It's gotten so big in recent years due to the Apple "introducing it" onto their Air Pod Pros. The only somewhat... good(?) thing about it is that you can easily switch between noise cancelling and passthrough, but honestly it's dumb as hell. Just take the earbud out.
Noise Cancellation has been around since the first In-Ear Monitors (IEMs) were invented. The only reason the layperson has never experienced noise cancellation before is because the greater consumer population didn't want to stick in ears well... In their ears. Of course until Apple made it cool.
IEMs were made for musicians to help them hear each other and keep in time while on stage by monitoring their own sound (hence the "monitor" part of in ear monitor). Since they're used in live performance situations, they need to cancel out hella noise. Because of their usual design, the noise cancellation on IEMs is and always has been vastly superior to ANC Bluetooth earbuds.
Nowadays with IEMs being much more affordable, it's possible to get complete and total silence while listening to music, with better sound quality, all for a fraction of the price of "good" ANC Bluetooth earbuds.
All Bluetooth does is jack up the price and lower the sound quality in return for the convenience of not having a cable. A cable which phone companies have forced away from the average consumer because they figured out how to steal away with more of our money via ANC Bluetooth earbuds.
TL;DR to anybody listening to music who cares about sound quality or noise cancellation and is using noise cancelling Bluetooth earbuds. Do yourself a favour and switch to some wired IEMs with a dongle.
