Most likely using BT.

I experienced my neighbors daughter playing on my M3.

Now all my devices BT switched off.

I did experience the same "not so funny" thing with my Essence MK2.

Hacked? No!

The problem : there is a "always open" default setting for bluetooth on a lot of B&O devices (not on my A9 mk2 but on my Essence mk2). So any teenager waiting in his parent's car in the front of your house at midnight can see the open Bluetooth speaker, connect his phone to it and blast his trash music at full volume (usually they go to full volume to try to listen to the speaker they are connected to). That's what happened to me.

The solution : B&O app/settings(the wheel at the upper right corner)/Products/Choose your product(s)/Configure/Bluetooth/Always open/Untick the box "Activate always open mode".

(The wording may differ in your product, I translated from the French).

I was joking about 'hacked'. But it was surreal trying to fight someone at 1.30am who was controlling my BeoSound 2 and nowhere near my home.

I'll take a look at the settings. Thanks.

When I travelled from Copenhagen airport in November last year I used my Beoplay H9i headphones and suddenly I got someone else’s music. This happened on and off for the entire flight. Like our phones mixed our units up.

I think B&O might have failed to correctly set individual serial numbers or something so the units all look the same. Or this was just very very bad luck 😂.

Thankfully the new AirPods pro came out the same day and I bought them and brought them with me, as well as my old AirPods. So I decided to use them instead.

Maybe the same thing happened to your Beosound. Another possible scenario is airplay 2 and that your Apple TV if you have one had HomeKit configures to allow nearby units to airplay to airplay enabled devices. This then can happen without being on the same WiFi network.

Hmm. This have Been a know issue for a long time. But actully is not an issue, 

but a function b&o have made, its the BT that stand always one in default,

The problem is it Now manual with the product anymore, so people dont know what is on default or how to turn off the function..

but that is why by it in a B&O shop and hopefully Get a personal service and Get it know before you Get home.

we tell most off the people about this issue, because alot of people we sell to live in apartment with alot around you.

but if you leave far from you nabour you never know this..

So the Mail problem is not the product it self, but the information that follow..

B&O need to Get better on this part, so many function witout any manual.. not Even a PDF document that can be update while the product living on all of the function.. 

cheers,
