A:Answer I've now owned both of these; G933. The only thing that the 633 has over this headset is simply the fact you don't need to technically worry about charging it, but it does have a problem where the USB port can get lose and cause connectivity issues (the 633 does not have a dedicated cable, it is a USB cable just like on the G933, but the innards have been gutted of the battery and wireless components.()
