DJ HEARTSTRING is a German DJ duo based in Berlin. Their sound sits at the crossroads of trance, eurodance, and high-energy club music, balancing euphoria with a soft sense of melancholy.

Formed by long-time friends Leo and Jonas, the project grew from a shared love for emotional dance music and late-night intensity. Their sets blend fast BPMs, pop-leaning melodies, and hands-in-the-air moments, without losing a raw club edge. Moving easily between underground spaces and large stages, DJ HEARTSTRING play with contrast and feeling, creating music that is direct, sentimental, and built to be felt together on the dancefloor.
