Coming from the Momentum TW3 compared to the new TW4:
The sound remains excellent with no major differences. The new TW4 supports the additional aptX Lossless protocol which has native uncompressed CD-quality sound, but very few phones support it, so I stuck with the very good aptX Adaptive.
Regarding sound quality, I will say what almost everyone says: they are simply amazing, especially when you easily adjust them to your liking through the Sennheiser app. Endless bass, tight, top-notch vocals, and detailed highs. A delight on Tidal Max! What impressed me (and from the previous model) is how dynamic their sound is and the complete absence of distortion no matter how much I pushed the volume (and they can get very loud)!
I believe the ANC is about 10% better - not a huge difference but they definitely offer a bit more quietness.
The Transparency mode remains quite good and seemed the same to me, although I have the impression that the wind doesn't bother as much anymore.
There is an upgrade in Bluetooth which is now version 5.4 and they also support the new Auracast with which countless headphones can connect to a transmitter. However, both of these upgrades have no impact on how I listened to music until now compared to the TW3.
I find the option to charge up to 80% very good so that the battery is less stressed for greater longevity (I do the same on my Lenovo laptop).
The shape, size of the headphones and case have remained identical to those of the TW3.
In conclusion, they remain one of the top true wireless headphones you can buy. If you are looking for quality sound and features (and your budget allows it), get them with your eyes closed! However, if you own the TW3, I don't see a significant reason to upgrade since apart from minor improvements in certain areas, their sound is almost the same.
