The Sound Burger is a portable record player developed by Audio-Technica of Japan. Originally released in 1983, it was brought back in an updated form in 2022. The original Sound Burger (model no. AT770) was marketed in the United States as the Mister Disc. It was battery operated was sold with a set of fold-away headphones, and was able to play both 33- and 45-RPM records. On 1 November 2022, to celebrate the anniversary of Audio-Technica, a batch of 7,000 new Sound Burgers were announced and available for purchase for $199.99 and quickly sold out. The units are all in red, with some changes from the original model such as: 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. Following its success, on 5 January 2023, Audio-Technica announced a wider re-release of this edition without the commemorative plaque. Now known as the AT-SB727, it keeps the changes introduced in the SB2022 model and is available in yellow, black, and white.
