Really nice earphones, software can improve.
I think these earphones are great. They sound very well, feel durable, and fit really nicely. The only thing I think can be improved is the pairing mechanism, at least with Android phones. Sometimes I feel like it's a bit inconsistent: there are times when there is no voice telling they are paired, but other times there is. And I feel like the amount of time I have to hold the button for turning on and pairing the earphones is somehow variable.
But overall, I think they are great and I am happy with my purchase.
