Absolutely useless - the device, the app and customer services
I bought the SoundForm Flow earbuds in airport customs and downloaded the app, as advised in the app packaging, but I keep getting a bug that states the firmware needs updating yet it won’t update. The customer services bot states that the app is not meant for use with the earbuds, despite the instruction manual advising it be used, and they claim that you can’t update the audio settings - avoid this app and the earbuds as they are junk
