It's only marketing. There is no integrated assistant. It's a plain old button that can be used to activate one of these useless voice assistants on your phone because some people like it. If you're like me, you can use it as an extra control to modify noise cancellation.
How does the Bose app talk to the device? Wireshark can probably be used to analyze it. Writing a simple free software replacement for the bad app could be a fun project and the result will no doubt be much better than their proprietary software.
I have, at [1], though this is literally the first time I dabble in android apps, so quality is alpha at best. I use it frequently ant works for me though.
There's a lot of protocols you can run over Bluetooth.
The BT dump tool can be run on the bluetooth device (eg laptop, phone) and so get access to the negotiated crypto keys oe cleartext version of the comms.
Sure, it’s less than ideal, but come on. There are far worse apps and it’s required to update the firmware. At least on iOS you’re also prompted to install it when you connect to the headphones for the first time anyway, so I would imagine adoption is pretty high.
I don't mean "it's not a high tech native experience with dark mode". I mean the app works poorly, all the time, and gets in the way of actually using the headphones. For example: whenever my headphones are paired with both my phone and laptop (because the app allows for two devices to be paired at once??) I have to manually disable my laptop in the app to listen to phone audio, the "drag down to connect" interface rarely works properly, etc. It really is a very poor experience when compared to BT headphones that don't require an app to manage their state.
You can politely ask Bose to disable Alexa the same way you can ask Facebook to "delete" your account. They disable the functionality you have access to while still collecting all the data they normally would and having remote access to turn on the microphone and listen in whenever they want without letting you know about it.
you're already buying a set of noise cancelling headphones with an integrated microphone from them. if you're afraid of Bose remotely activating the microphone, that risk exists without the Alexa functionality. Even if the headphones didn't have a usable microphone, they're noise cancelling, meaning they have a microphone for that purpose.
Bose is not an advertising company. They have (had?) less incentive to collect my data. Amazon on the other hand peppers the market with tons of low cost shitware devices that have Alexa integrated in for no reason other than to harvest ambient sound data for Advertising purposes. The fact that Bose is partnered with Amazon makes it less likely I'll buy any of their products now, even without the Alexa since I now know they're cool selling user data (or at least cool accepting money to add Amazon/Google's crapware apps in their otherwise nice hardware).
You can use the headphones without the Bose app, and if you really need to configure something, download it, configure, and delete. The assistant integration is totally opt-in
