Prevent headphones from waking up my Macbook

I have a MacBook Pro. I also have Bose QC 35 wireless headphones. If I put my laptop to sleep, and after a while turn on my headphones, the headphones will wake up my laptop, even if I previously disconnected them in the Bluetooth section of MacOS. How to prevent this behaviour, while still keeping the option to wake up the laptop with keyboard/mouse/trackpad?
