Replace the bayonet mount. I had the same problem with my a5100, bought a metal bayonet mount from Amazon and fixed it in about 5 minutes. The plastic one on mine was broken / fatigued and didn’t hold the lenses tightly, thus the pogo pins didn’t properly contact.

I came to this article to see if there were any hidden internal storage (& wifi?) with the hopes that these could secretly support Apple’s new lossless offerings with a software update - use bluetooth / (missing) wifi to transfer the entire file to the headphones rather than stream over bluetooth, which doesn’t have sufficient bandwidth for lossless audio (IINM).

I’m not even sure these can resolve lossless audio compared to AAC, but for 550 USD, they should. I’m disappointed they only have one driver per can, should at least be bi-polar.

The tear-down reveals 256 memory… is that enough? Maybe it’s only enough for its OS/FW & maybe store a compressed song or podcast… I could have sworn I read somewhere that AirPods transferred the file rather than just stream via Bluetooth… IDK.

Honestly, at this price point, 83% more than the OG HomePod which has an A8 & 16GB, they should at least have AirPlay & a few GB built in to support higher fidelity audio.

They are super comfortable & don’t creak like my plastic Sony’s.
