How to fix problems with Bose QuietComfort 35 II - SoundGuys
Original QC35 still on 2.5.5, should I upgrade? Did they fix the ANC problem with the new firmware? : r/bose
My new Bose Qc 35 II. I have tested both this and sony XM4 and gone with Qc35II.So much happy specially with 4.8.1 firmware. I wonder it is competing with 2020 XM4
