I got the Robin. It does have wireless charge.
I have a yootech wireless charger that I place the case on and it charges it. Yootech lights up green to indicate it is working. Have never had to use the USB C input to charge it. They are a step up in terms of sound quality compared to the Airpods Pro 2, IMO, but just not as good when it comes to features. APP2 is also no slouch in SQ. I would definitely pick these up if you want a pretty solid, good sound TWS for a great price. They could have easily sold these for $250-$300 and they would have been competitive, given how good the tuning is.
Couple more notes: In my experience the Moondrop app is more reliable with these than their USB C dongles. Also actually lets you change settings on iPhone, where-as the dongles can only be adjusted on Android. Also worth mentioning that it seems to use a separate BT connection for being able to change settings. I use them exclusively with my desktop PC and can still change EQ settings from my phone at the same time with no hitching or cut out. These are very under-rated IMO. I hope Moondrop comes out with a standard version if they stop making the Honkai version in the future.
