Left earbud died
The sound on these was okay - not complaining given the low price. But the left earbud was wonky from the beginning. Often will not power or connect even though fully charged and even though right one connects. For the last 7-10 days, the left never comes on despite repeated attempts, re-charging, re-connecting, rebooting phone, etc.Works great
Gaming or music. The headphones sound great without the app. But if you’d like more capabilities and options the app helps a lot.
