I recently bought the headphone, i am not sure whether my issue is related to the update firmware version or not but i am getting frequent disconnection issues on linux distros only. On windows and iPhone it's working smooth but on linux (fedora, Ubuntu) i am facing the problem. I hope Bose will verify the issue and try to fix it ASAP.
Thank you for posting and welcome to the community.
As your headphones are working fine with your iPhone and Windows device, it would appear that the issue is coming from your Linux device. We do have a handy post for using Bluetooth headphones with computers. It is tailored more to Windows and Mac users, but you should find some helpful information as well.
Also, given that the issue is only with the Linux device, it may be worth seeking support from the manufacturer and other Linux users for assistance with this.
