I’ve had this mentioned before and it makes me think that people do not understand the problem here.
Being signed in to the app should have no bearing on whether or not EQ settings are retained INSIDE of the earbuds… independent of the app completely.
Once an EQ (or HearID) is applied to the earbuds, it should be semi-permanent and should be stored in the earbuds whether the app is never used again or not (or completely removed from my phone). I have though signed in, as well as signed out, signed in again… removed the app/reinstalled the app… no difference: the EQ sound is lost in the earbuds during charging in the case and must be re-applied before every use. But again, if the EQ (or HearID) is stored in the earbuds then I should be able to completely remove the app and never have to use it again once applying a sound profile I like to the earbuds.
With my Soundpeats earbuds, I use the app once, apply an EQ I like, and the earbuds retain the EQ sound forever (or until I change it in the future). I can charge the earbuds, turn them off, use them on my Apple TV or any other device and the new sound profile is alway retained.
With the Soundpeats Liberty Air 2, as soon as I put the earbuds into the charging case and turn them off, the EQ is lost, and the sound reverts back to the stock/default sound. So, after charging I always have to pair with my phone, open the app, turn off the EQ (because the app remembers the last setting), then turn it back on to apply the EQ over to my earbuds…
The earbuds will then save this sound and I can use the earbuds with this EQ on my phone, or I can disconnect and use on my Apple TV and the EQ is retained… UNTIL at the end of the day (or whenever) I put them back in the charge case. Again, the EQ is lost inside the earbuds, so next time I use them I have to pair with the phone, open the app, and re-apply my EQ over to the earbuds. It’s a huge pain and not at all what other earbuds do… and also not what Soundcore says these should do.
I’ve explained the issue to them on the phone and in many emails, and they are always originally confused (and tell me to do things like sign in and out of the app which is nonsense) and then finally tell me the “EQ settings should be saved inside the earbuds”.
Basically, imagine if every time you used your earbuds, you had to open the app, and set your custom controls that you like… and every time after you charge your earbuds, your custom controls settings are lost (revert to default) so you have to open the app before each use and set them how you like. THIS is exactly what is happening to the EQ sound (coincidentally, the custom controls ARE intact always, even after charging).
