Soundbrenner is a music technology company founded in 2014 and headquartered in Hong Kong, with roots in Berlin's startup scene where its founders built the first prototype by salvaging a vibration motor from an old flip phone. The company is best known for pioneering wearable devices for musicians, beginning with the Soundbrenner Pulse — a vibrating metronome worn on the wrist or other parts of the body that lets players feel the beat rather than hear it. The Pulse was crowdfunded in 2015 and helped establish a niche category of haptic practice tools.

The lineup expanded with the Soundbrenner Core and Core 2, multi-function wearables that combine a vibrating metronome with a chromatic tuner, decibel meter, and smartwatch features in a single device. The company also makes Spark, a practice companion aimed at younger musicians, and the Wave in-ear monitors designed for stage and studio use. Soundbrenner has partnered with Minuendo on adjustable earplugs as well.

Beyond hardware, Soundbrenner publishes The Metronome app for iOS and Android, which integrates with its wearables and serves as a free standalone tool. The brand's identity centers on making practice more engaging through tactile feedback and tracking, positioning its products toward musicians across instruments rather than guitarists or drummers exclusively.

Soundbrenner has 5 products cataloged on Equipboard, including Metronomes. Their gear is featured by 1 artist, with the strongest followings in Rock and Blues. Notable users include samuraiguitarist.
