I bought an NC700 yesterday. Everything works fine, but I can't see the equaliser in the Bose app. The headphones are refurbished, so there's no packaging. They came with accessories in the case.
I read somewhere that the firmware needed to be updated, but both the app and the update website show that the headphones are up-to-date. The app shows the current version 1.3.1-2028.
Keen to know if anyone else faced a similar issue and how you fixed it.
Thanks!
