Techniques for reliable communication between wireless earbuds in a high-interference scenario

A method for wireless communication at a first wireless earbud, comprising:

• performing a signal strength measurement across a first plurality of channels that are available for communications between the first wireless earbud and a second wireless earbud;
• detecting that one or more interference metrics associated with the first plurality of channels satisfy an interference criterion in accordance with the signal strength measurement across the first plurality of channels;
• reducing an upper limit transmit power for the communications between the first wireless earbud and the second wireless earbud in accordance with the one or more interference metrics satisfying the interference criterion;
• and
• communicating with the second wireless earbud using a frequency hopping across a second plurality of channels in accordance with reducing the upper limit transmit power, wherein the second plurality of channels is a subset of the first plurality of channels.
