Communication of wireless headphones

A wireless audio system, comprising:

• a primary wireless headphone configured to:
• receive, from an audio source, audio information using a short-range wireless communication protocol;
• transmit, to the audio source, a first message indicative of whether the audio information is successfully received by the primary wireless headphone;
• and
• transmit a communication parameter associated with the short-range wireless communication protocol used between the audio source and the primary wireless headphone;
• and
• a secondary wireless headphone configured to:
• receive, from the primary wireless headphone, the communication parameter;
• snoop, from the audio source, the audio information based on the communication parameter using the short-range wireless communication protocol;
• and
• transmit, to the audio source, a second message when the audio information is not successfully received by the secondary wireless headphone,
• wherein the first message and second message determine whether to re-transmit the audio information, and
• the primary wireless headphone does not receive the second message from the secondary wireless headphone.

A method for wirelessly communicating audio information, comprising:

• receiving, by a primary wireless headphone, audio information from an audio source using a short-range wireless communication protocol;
• transmitting, by the primary wireless headphone, a first message to the audio source indicative of whether the audio information is successfully received by the primary wireless headphone;
• transmitting, by the primary wireless headphone, a communication parameter associated with the short-range wireless communication protocol used between the audio source and the primary wireless headphone;
• receiving, by a secondary wireless headphone, the communication parameter from the primary wireless headphone;
• snooping, by the secondary wireless headphone, the audio information from the audio source based on the communication parameter using the short-range wireless communication protocol;
• and
• transmitting, by the secondary wireless headphone, a second message to the audio source when the audio information is successfully received by the secondary wireless headphone or a third message to the audio source when the audio information is not successfully received by the secondary wireless headphone,
• wherein the first message and second message or the first message and third message determine whether to re-transmit the audio information, and
• the primary wireless headphone does not receive the second message from the secondary wireless headphone.

A wireless audio system, comprising:

• a primary wireless headphone configured to:
• receive, from an audio source, audio information using BLUETOOTH protocol at a first frequency;
• and
• transmit a communication parameter using an amended BLUETOOTH protocol at a second frequency lower than the first frequency, the communication parameter associated with the BLUETOOTH protocol used between the audio source and the primary wireless headphone;
• and
• a secondary wireless headphone configured to:
• receive, from the primary wireless headphone, the communication parameter,
• receive, from the audio source, the audio information based on the communication parameter using the BLUETOOTH protocol at the first frequency;
• and
• transmit, to the primary wireless headphone, a first message when the audio information is successfully received by the secondary wireless headphone or when the audio information is not successfully received by the secondary wireless headphone using the amended BLUETOOTH protocol at the second frequency,
• wherein the primary wireless headphone is further configured to transmit, to the audio source, a second message indicative of whether both the primary wireless headphone and the secondary wireless headphone successfully receive the audio information based on the first message using the BLUETOOTH protocol at the first frequency.
