QC35 I on QC35II body?

Hi.

Is it possible I have the first version of these headphones on the QC35II body? 

The bose app tells me my version is QC 35 made on 24/9/16. 2.5.5 Firmware at the moment. 

But I do have a button on the left ear that's supposed to change the ANC levels. Never managed to make it work though. It just tells me how much battery I have left and device i'm connect to. I bought them used at a fairly decent price and after close inspection, everything seemed fine to me. Original box and accessories as the ones in the store. 

Another thing I noticed is that the battery discharges overnight when plugged off. After 10minutes it's up to 100% again and I'm able to use them for >6~8h straight hours. 

 

How did the firmware update on these worked out? App tells me I can upgrade to a newer version but i'm afraid i'll experience poor ANC or other problems.
