Finally got my phantom air working properly I think. The drop out are mostly gone for me and really like the sound on them.
On the day i received my phantom air, the back on the right bud popped open when i accidentally dropped it. So glad it did as it allowed me to see the inside.
There are 2 pins that press against a copper foil that is placed against the back cover. I am making the assumption that this is potentially the antenna of some sort. (The pins has some spring on them like a watch band pin)
Anyway, what I ended up doing was grab some extra copper foil/strip. Fold it into 4 layers and placed it against the original copper foil. I place the cover back on and tapped it down with strips of duct tape. (I'll get it glued one day when I am happy that the issue is definitely resolved)
I find that it needs to be pressed down properly against the pin, not just touching the pin. After that, I stopped getting drop out accept occassionally as any TWS earbuds do (not any more compared with my Erato Muse 5).
I think update 26 helped explains this best. Trinity mentioned about the battery causing the dropout. I think what has happened is that the mass manufacturing caused inconsistency with battery sizes. There must also be issue with the glue used as it's not keeping the back cover tightly secured on. The looseness of the pin against the foil and back cover I think is causing the dropouts for many. Unfortunately, I think this issue must have came about during mass manufacturing and wasn't picked up earlier.
Hope this help others.
I'll try to do a video one day if anyone is interested.
Now, if someone could explain to me what each different filter's effect might be, that would be great!
