Bought the Module Y Earbuds earlier this year. Opened the box and proceeded to charge up battery's. After the charging process I followed the instruction's and tried out the earbuds. Linked to the Bluetooth device on my laptop and proceeded to listen to some music. The pairing of the earbuds was quick except for the following. The Right earbud performed as expected it did Very Well. The Left earbud was non-responsive. No sound other than a couple of tones (beeps). I checked the power connections which appeared okay. Went to the ADV-sound Support page and followed the directions for resetting the earbuds. No difference in the functioning of the Left earbud. My initial analysis is that either the base unit and/or the Left earbud are not receiving any power. The Right earbud is receiving power.
I have contacted the ADV support group and have established an email correspondence.

Ordered Eartune Fidelity U for my IER Z1R. Best tips with this IEM after trying lots of eartips. Solved the recessed mids problems with some songs, especially male vocals. Hearing more elusive details too. The only thing making me hesitate to give a 5 stars rating is shipping is so so and expensive.

The Eartune Fidelity UF-A I ordered didn't fit (who knows, could be my ear canals!) But the customer service at ADV was excellent. Very quick and responsive to try anything to make it right. I would order from them again for sure.

Excellent product and an even awesome customer service. The sound is much better now and there’s no sound leak. Doesn’t slip out of my ear so easily as with the stock ones.
Finally can use my air pods with out them falling out of my ear!

I’m so very pleased to rate these tips. I was allergic to the ones that came with the AirPods Pro and these tips where a miracle savor for me. Just about to give the pros away, tried buying other tips that’s didn’t help ADV thank you 5 stars for sure.
