2022 limited edition

On 1 November 2022, to celebrate the 60th anniversary of Audio-Technica, a batch of 7000 new Sound Burgers were announced and available for purchase for $199.99, which quickly got sold out. The units are all in red, with some changes from the original AT770 model such as: a new AT-SB2022 model number, a rechargeable battery charged through USB-C, Bluetooth audio connection, normal buttons along with indicator lights instead of toggle switches, and a plaque to the back commemorating the anniversary and bearing the serial number of the unit within the batch.[6]

On 5 January 2023, Audio-Technica announced a wider re-release of this edition without the commemorative plaque.[7] Now known as the AT-SB727, it keeps the evolutions from the SB2022 model. It is available only in yellow or black in most of the world, a white version also exists for Asia and Australia.
