I was able to do some research and make the following selection:
If you mainly watch TV at home:
- Sennheiser RS 195 → Built for that, unbeatable for films.
- Sennheiser Rs 195 (no noise cancellation, 18 h, wireless)](

- Sony WH-1000XM6 → Best overall package in terms of workmanship, weight, sound and operation. Provided your TV has Bluetooth.
- Sony WH-1000XM6 (Active Noise Cancellation, 30 h, Wired, Wireless)](

- Bowers & Wilkins PX8 S2 → Excellent sound, very cinematic, equally excellent for music. Can also be connected to the TV via Bluetooth, provided the TV can establish a Bluetooth audio connection.
- Bowers & Wilkins Px8 S2 (Active Noise Cancellation, 30 h, wired, wireless)](

The decision is also very personal as to which sound you like best. I liked the Sony and B&W sounds better than those from B&O.
