Hi, I am on my third qc35ii pair, the first one i bought was from Amazon which looked a bit worn out straight out from the box (returned). The second was bought from Bose online shop, which had a bluetooth connection issues as well as a clicking/ creaking sound from the right ear whenever i move my head. I reported this and returned to Bose for refund. I ordered the third pair (current one) from Amazon as they were on discount to give Bose another chance, but the creaking issue is still there!! The noise goes away if i press the U shape ear piece holder. This is clearly a structural issue. All the headphones i tried are built in December 2018.
Has anyone got the same issue? I got bored of keep replacing the headphones!
