Bluesound Pulse M - Will Bluetooth glitch when I use my device?

I am about to return a B&O bluetooth speaker because it cuts out when I use the device I am playing from.

The reason given by B&O is "Bluetooth Codec used is AAC ... the bandwidth of the connection is wholly reserved for music playback as the app connects to the speaker via an independent Bluetooth Low Energy connection" they do not consider it a fault

Am I going to experience this same effect e.g. music streaming from Spotify cutting out when I close a tab (or any other CPU intensive process) on my laptop with the Bluesound Pulse M?

I have seen a report of "glitchy Bluetooth" for a Ruark unit so I suspect this is might be a common problem.

I have older BOSE and AUKEY Bluetooth speakers which don't exhibit this problem.
