If anyone is planning to buy them, here's my review after 30 days:

They're good, but definitely, due to their disadvantages (check link below), they can't be called flagship or high-end headphones.

The lights are nice, but it would be better if Samsung engineers paid more attention to basic functions and ergonomics.

- the earbuds need to be placed very carefully on the inductive charger. It only works in a specific place, even cheap headphones from China don't have such problem.

- problem with the case and headphones inside heating
up very intensely. For those who may not know, high temperatures negatively impact batteries, degrading them, shortening their life, not to mention other risk - this is a serious mistake by Samsung's engineers, unworthy of a flagship.

Short:
- PC connection problems - even cheap headphones from China don't have such problem - this is a serious mistake by Samsung's "engineers", unworthy of a flagship.
- positioning in the charger - it's okay, you get used to it, but it's an ergonomic mistake.

I rate them 3.5/5.
I've been using SB3Pro for 30 days with my Samsung Galaxy S24 Ultra.
Definitely, due to their disadvantages (link bellow), they can't be called flagship or high-end headphones.
Considering disadvantages they are worth ~€120, definitely not €250.

With One UI 7 you also have integration with Gemini, you can start it with a gesture, e.g. longer squeeze the earpiece (must be set in the wearable), or by voice "ok Google".
Tested on Galaxy Buds 3 Pro with Samsung Galaxy S24Ultra.
