Cheapest I've seen it for this latest model for 45 bucks. It's a no brainer. It has LDAC If you have a supported Android device.
Takes about 2 week, but meh, I still have my Air3 going strong with no issues after a year so.

I used to have the Air3 and upgraded to the Air3 Deluxe HS when I lost one of my earbuds.
Can't say I notice much difference between the two besides the physical size difference of the case but I've had nothing but problems with getting them to turn off automatically after placing them back in the case - don't know if the contacts are broken in the case (seems to charge so I don't think they're) but I'll have the earbuds in the case but my phone will still be connected to them. Doesn't happen all the time but every time I put my earbuds back I'll double check it now which is annoying.
