After not using them for a day, today I put them into my ears, and only the left one is working. Trying to figure out what is wrong, I try disconnecting, re-connecting etc. only to find out in the end that the right one is completely discharged :( Again, this is after a whole day of both sitting inside the case, and the case being 100% charged. So, something is still wrong with the charging ever after these firmware updates.
*edit* also, I might be crazy, but it seems like the ANC is not working as well as before? The hum of the heating system in my office is still audible now when I turn the ANC on, and I know that before it sounded as if the system just completely stopped when I enable ANC. I remember being amused by how much it seemed like it shut off anytime I'd put them in my ears. It's not like that anymore. Did they nerf this via firmware updates?
