The thing I like about Bathys & PX8 for that matter is just a clear sliding off switch. I find it so frustrating with various bits of tech (XM4, Qudelix 5K, Airpods Max, Go Blu, etc) when the off switch is some press and hold scenario, and it's often ambiguous whether it's turned off. I don't want to hold a button down for 4s to turn off a device and wait for a tone or led to flash, it's really poor user experience design.Personally I'm very happy that Bathys have physical buttons and not touch controls. I've had 2 headphones previous with touch controls, and if your fingers are a little moist sometimes they will misunderstand the command or go haywire. The volume rockets suddenly to the sky, or you are listening to a good vibe and try to turn up the volume and it skips to next song. So with headphones I actually prefer physical buttons
Bathys get that right, It's simple and immediate to slide between DAC, on and off.
