@adrianpdI don't work for Bose but this is considered by them a 'design' feature which they adapted when it became part of the Bluetooth 4.x standard years ago. It is called "Bluetooth Low Energy" (BLE). As Bose does not considered it a bug (it's a feature), they won't remove it. I personally have soapboxed on this issue for years. It should have been a three way toggle just like your vehicle headlight switch - on, off, and automatic (car decides). But on the top Revolve button, it is only ON and BLE. No off. It's an engineering thing to me - poorly designed from a user interface perspective. But Bose wants other devices to turn it on - like the Bose Connect app (which can put the Revolve into 'party' and 'stereo' modes) and when paired devices turn themselves on like laptops. It's just many of us users don't agree with Bose's assumptions of use and they should have had an option to allow us to define what off means for the top button. But there is currently one saving grace for the Revolve at least, the multifunction key. Not an optimal way of turning it off and prone to forgetting to use, but if you hold down the multifunction key until all the lights blink it will really be off.
You can measure that by obtaining a free app in the Apple or Google Play stores which measure and detect for the BLE signal. On my iphone I use "BLE Scanner" and "BLE Finder". If the Revolve is truly off, the apps will show no BLE signal.
