Using Radio Transmission Technology, older products communicated audio in the analog domain. Nowadays, most products operate in the digital domain. The benefits of this are Higher Quality Audio (therefore greater clarity), Digital Encryption which enables much higher levels of security and Multichannel Communications allowing more systems to be used in the same space without interfering with each other (typically known as crosstalk in the analog domain).
