determining, by the first earbud, the first audio data comprises a voice; or

receiving, by the first earbud from the second earbud, first data corresponding to the second earbud determining the second audio data comprises the voice.

11. The method of claim 10 , wherein determining the second quality metric corresponds to higher audio quality than the first quality metric further comprises at least one of:

determining, by the first earbud, that the first audio data comprises a wakeword; or

receiving, by the first earbud from the second earbud, second data corresponding to the second earbud determining the second audio data comprises the wakeword.

12. A system comprising:

at least one processor; and

at least one memory including instructions that, when executed by the at least one processor, cause the system to:

detect, by a first earbud, first audio corresponding to an utterance,

determine, by the first earbud, first audio data corresponding to the first audio;

determine, by the first earbud, a first quality metric corresponding to the first audio data,

receive, by the first earbud and from a second earbud, a second quality metric corresponding to second audio data corresponding to the first utterance,

determine that the second quality metric corresponds to higher audio quality than the first quality metric,

13. The system of claim 12 , further comprising additional instructions that, when executed by the at least one processor, further cause the system to:

receive, by the first earbud from the second earbud, first data corresponding to the second earbud detecting second audio corresponding to the second audio data; and

send, from the first earbud to the second earbud, a command to send the second audio data.

14. The system of claim 12 , further comprising additional instructions that, when executed by the at least one processor, further cause the system to:
