Overall great headphones that could use a little software tweaking. Especially in ANC - it is strong enough, but rather there is a problem with quality. For example. in the wind, it quite often does not mask the sound of the wind "gust", and it also affects the overall ANC a lot. It often happens that the overall ANC fluctuates in intensity. The same is true in a quiet office with recuperation and transparent mode, where one has very quiet music and ANC set more to transparency (ambient sensing). This fluctuation is not entirely pleasant - one perceives it. Horrible sound out of the box - like really bad (standard equalizer didn't help much) and the sound was even quieter, and slightly out of tune (distortion) - like old "tin cans" - no treble, with crackling mids, and too much bass. It was only after a firmware update, forced reset, and connecting to the Mac and turning up the volume from the Mac that it improved (could it be the dual SW volume? ). Still not great. After about the first hour of listening, the headphones "ran" (weird enough) and together with the parametric equalizer (sound personalization) they have been playing really great ever since! After using it for a few hours in the office, where it is 23 degrees, I have very slightly sweaty areas under the ear pads. But it's not uncomfortable. Rather, the question is how it will be in the summer, e.g. Outside. Lack of automatic ANC switching according to movement - no possibility to increase transparency, e.g. when you start up, like Sony, which is a shame. However, the location-based setup is better than Sony's (home, office). If I were to compare it to the WF-1000XM5 (the earbuds I have), they sound a little better overall and the ANC is more effective in the office and outdoors and a little less so on the tram. With Sony, however, you can tell the difference when using LDAC - absolutely clear sound without noise and distortion. Unfortunately, I can't use adaptive AptX on the Momentum 4 because Samsung doesn't support it. However, it sounds very good on the Mac (AAC). They have pretty good controls, gestures are fine and accurately detected. The call quality is very good. It just doesn't completely cancel out the surrounding noise (screaming children, tram, etc. ), so meeting while walking on the street will not be ideal. I can recommend them overall. Just watch out for the ANC. If you plan to use them exclusively outdoors while traveling around town, they're not exactly a great choice. For the office or for listening at home, however, ideal.
