Few things I like and appreciate about WF-1000XM4.
I really dig this finish. Far better in person. The case and the units have this unique textured finish, and I'm glad I chose this color scheme.
Excluding full-size HPs, league above anything I own and have heard. Superb ANC combined with excellent passive isolation makes this best in class. Best of all, no ANC buzzing/white noise!!! It's one of the things that bother me the most with ANC TWS/HPs, and here It's dead quiet.
I really like the fact that I can insert them in my ears and adjust them without triggering the touch interface. Usually I disable the touch features on other ANCs because of this. I can't overstate the importance of this. Touch sensors are very accurate as well.
Sound Isolation - Passive isolation is excellent with the supplied hybrid foam tips. This is definitely going to be my travelling set, well whenever that happens. *one this to note, slightly difficult to get a proper seal.
Sound wise, no complaints. Need a bit of EQ out of the box. Unwanted resonance, an area where TWS typically suffer, is minor compared to many other offerings.
Overall, I'm happy with the purchase.
