9:27pm pass Fit check, listening to Apple Tv 4K YouTube. While connected to iPhone hearing more foot booming sounds that weren’t there before. Same booming sound when connected to Apple TV. Is the same in ANC and transparency. As happened on last set of AirPods, could not control volume with Apple TV remote unless I reconnected AirPods multiple times in the menu.
9:38pm put back in case, connected to iPhone and ran fit check. Bass is noticeably weaker than before. Thuds from footfall continue.
9:40pm “forgot” device on phone Bluetooth settings and reset AirPods Pro. Audio quality still seems degraded with weaker low frequencies and distorted mids and highs.
9:50pm tested old AirPods first generation. Bass was much more pronounced. Restarted phone. AirPods Pro showed up as connected, but audio played through iPhone speaker not AirPods. Placed back in case and took out again to reconnect. First failure on right AirPod. Second check passed in both ears.
10:20pm Next fit checks failed continuously on right only. Now I’m hearing constant rumbling in the right and thud sound every time I take a step. Removed and cleaned ear tips. Inspected and saw no noticeable dust. Right side always fails check no matter which ear tips are used. Paced back in case.
11:08 decided to test one more time. Now failing fit check in both ears.
