I received my G5 and I like everything about it so far except for the Bluetooth. The Bluetooth connection is pretty awful especially when using LDAC and when I change the setting to optimize for audio quality, I'm getting frequent dropouts and the devices are literally next to each other at home. With my older devices, this was never an issue.
Only other thing I wish the G5 came with was a little traveling pouch. Nice little leather pouch would've been nice. But otherwise, all the other accessories are great.
Battery life is also amazing on the G5. LDAC does drain the phones battery rapidly though. My phone will probably run out before the G5 does.
