Just picked mine up after they were delivered to a shop for me. First impressions are very favourable indeed from a sound quality perspective. I tried the normal AirPods and disliked them greatly but these seem to be perfect.
Can an owner of these perform a test for me? Go into a quiet room. Connect them and turn noise cancellation on. Don’t play any sound. Wait five minutes. Do you hear any buzz or mild thump sound?
Some noise cancellation headsets have issues with prolonged silence. Hard to find reviews that do this test.
