LESRSO
Our Story
Fulai Zhu grew up in a small town where the only way to hear music was through cheap earbuds that fell apart in weeks. When he moved to Shenzhen for college, he was shocked by how much premium headphones cost — and how little of the price actually went to the sound quality.
LESRSO was his answer: wireless earbuds engineered with the same acoustic chambers used in $200 headphones, but at a price that made sense. The name combines "less" and "reso" (resonance) — less markup, more sound.
The phone case line came from a simple observation: everyone at his engineering lab used a clear case that turned yellow after a month. LESRSO's TPU case stays clear, stays protective, and stays lightweight — just as a case should.
