I have been trying to solve the missing sidetone thing on my brand new QC35 II on an iPhone 6s. Fiddling with both the headset, the Bose Connect App and the iPhone, I suddenly got the prompt to connect a second Bluetooth connection, both of which are active at the same time to the same set of QC35s. See attached photo.
Can anyone explain what this is? And might it solve the sidetone thing?
Thank you so much for posting in the community! That's a great question. So the reason why there are two options for your headphones are because there are two options for which Bluetooth profile to use. The LE just stands for Low Energy. Low Energy BT is basically just the exact same connection but is engineered to consume less power and be more efficient.
I hope this helped answer your question!
Have a wonderful night and take care,
OK, thanks, but how do I get it to connect to the Low Energy version? If I remove the other one (not LE), then I lose connection with the headset...
And, is there any functionality I lose by using LE?

Without the LE connection, connecting the headset to the phone might take a bit longer as there wont be a low-energy hand-shake already make between the two.
OK, thanks, @James_S
However, it seems it only tries to connect - and connects - with the normal profile. I can manually connect the LE in parallel, but it seems not to give the benefit you're describing, then?

Just a side note regarding the two connections. My headphones had intermittent dropouts until I removed the LE connection. Now they work fine with only the one connection.
