User asked a question. Updating to the recent 2. I've done a factory reset from holding touch capacity of both earbuds in case aswell as initializing within app, to performing soft reset with one earbud in case while plugged to outlet and just opening and closing the lid for each earbud five times. None of it resloves the issue. Or is someone knowledgeable and offer a solution?

I am impressed with them after 2 weeks. I've been an owner of the Sony WFXM4 earbuds since December , and ever since a firmware update around that time, I've noticed a significant battery drain issue specifically with the left earbud.

It's always been on stable connection. We're sorry to hear what happened on original unit and glad to know you already received the replacement.
