Well, first of all the earbuds do not last nearly enough time as it is advertised. With normal mode on and spatial mode off, they seem to last for about 4 hours if I am lucky. I work and use them for 7-8 hours and I have to charge them more than once something really unacceptable. I even have to charge the case daily!
Also, the right one tends to lose battery more fast than the left one , something quite annoying.
Another thing that has happened the last few days is that the controls suddenly stopped working as well.
The customer support is late in their answers if they manage to answer any of your concerns and of course they do not accept these problems.
It seems like this company does not really care for their customers or at least this has been my personal experience. Proceed with HIGH caution with any of their products.
