All good
TOM delivery: fast and trouble-free; as usual.
The headphones: excellent ergonomics and great comfort, effective noise reduction, very good autonomy (one day in Bluetooth), excellent reproduction in all frequencies and, icing on the cake, very low latency time.
As a bonus, a well-designed carrying pouch is sold with the headphones.
After two weeks of use, I can only praise the qualities of the SENNHEISER PXC 550-II WIRELESS.
This is my third headset; it far surpasses the two previous ones, which were not low-end headphones...
