It works well on a scooter helmet. It's comfortable and doesn't bother me.

Yes, that is possible. On the right headphone cable are the controls for volume and sound attenuation. However, after switching on, the headphones search for the last connected Bluetooth devices for a while and report the failure by voice. After about three attempts, however, it is quiet.

Yes, the noise cancellation works as soon as the headphones are switched on, even without a Bluetooth connection to a device. Attention, however, you must set the standby timer in the app so that the headphones do not switch off prematurely.

No, unfortunately this is not possible.

The manufacturer himself could only give the following dimensions on request: 15.2 cm x 16.5 cm x 1.9 cm (HxWxD) (63.8 g)

Counter question... why shouldn't it be? Your device (Hady/Laptop/PC) ensures that audio works and is functional for all software... you can also use a cheap 9.- USB headset for Skype Business. I have the Bose QuietComfort 35 and use it on all devices... also at work and with Skype for Business.
