Thay are good only on music , connecting on what’s app, viber , but don’t deliver the Voice to ather side , not good at all
on phone calls , no mic , not connecting to phone calls . Disappointed 😔 westing money .
Unfortunately, these did not connect very well, only one ear bud would work and I had to return. Looking at some reviews, it appears to be an issue with these previously reported. It's a shame, as there doesn't appear to be any support from the manufacturer or update on the software, I believe the issue is software/firmware rather than hardware.
