//I have already praised the streaming function via the charging case. I edited a small audio production using the Bowers & Wilkins PI7 wirelessly and without any problems. If you want to (and you have them), you can connect another pair of headphones from the Bowers & Wilkins family wirelessly to the streaming case. In our test, this worked without any problems with a PX7, but could only be paired after the PI7s were in the case. The p17s can be operated in parallel – that’s all there is to it.//
