1. An audio device comprising:
a first earbud configured to:
establish a first wireless link with an audio source; and
receive, from the audio source, audio information over the first wireless link;

a second earbud configured to:
establish a second wireless link with the audio source; and
receive, from the audio source, audio information over the second wireless link,

wherein the first earbud and the second earbud are further configured to communicate with one another over a third wireless link;
wherein at least one of the first earbud and the second earbud comprises:
a measurement circuit configured to measure respective signal strengths of the first, second and third wireless links;
a computation circuit configured to compute a difference in signal strengths of the first and second wireless links; and
a determination circuit configured to determine if an operating environment of the audio device is an open field environment which is void of any reflectors for Radio Frequency signals based on the computed difference and further based on the signal strength of the third wireless link.
