They arrived earlier, and fully charged.
First impressions, they seem a tad more substantial than my other budget wireless (Xvive, Dinner, Getaria) and the sound quality seems to be better, although at the moment I'm just playing through headphones.
There are some nice touches, like the battery indicator and the matching green 'on' light. The hinge has sufficient resistance so that it stays where you fold it.
Here's the biggie though, there is some interference when my phone is near, although to be fair I only noticed it when my phone was next to the receiver.
