1. A method comprising:
establishing a first wireless connection between a first device and a second device, the first wireless connection using a first communication protocol;
establishing a second wireless connection between the first device and the second device such that the first wireless connection and the second wireless connection have both been established;
transmitting audio data via the first wireless connection;
determining, using a processing device, a switch should be initiated based on one or more signal quality metrics representing an estimate of a quality of the first wireless connection; and
switching to the second wireless connection using a second communication protocol, the switching comprising beginning encapsulation of the audio data in Bluetooth packets, performing data packet synchronization operations, and seamlessly transmitting the audio data via the second wireless connection in accordance with the second communication protocol, wherein the Bluetooth packets are encapsulated in one or more packets of the second communication protocol, and wherein the data packet synchronization operations align audio data while simultaneous transmission is occurring on the first wireless connection and the second wireless connection.
