When you use the internet to make a call the sound sampling rate is higher (16k Hz) than when you make a call using a cellphone network (8K Hz). This is why sound quality is better when you call using the internet. The reason for the low sampling rate is because when you make a call through your cellphone network it passes through the public switched telephone network (PSTN), to save bandwidth they lower the sampling rate.
VX-1 needs an adaptor with a rating of at least 5V/500mA. As long as your AC adaptor’s rating is the same or more (e.g. 5V/1A, 5V/2.1A) they are compatible with VX-1. If you have an iDevice, your iDevice AC adaptor is also compatible with VX-1.
