RISIR
Our Story
Shengli Chen founded RISIR on a bus ride home when her $200 earbuds died and she couldn't afford to replace them. She realized that good audio shouldn't be a luxury — it should be as accessible as a bus ticket.
The name is a stylized spelling of "resistor" — the electronic component that controls current. RISIR products control the chaos of daily life: noise cancellation that works, a charging case that doesn't die by lunch, a phone case that actually protects. No hype, no influencer marketing, just reliable tech at a fair price.
Every RISIR product is tested for 1000+ hours before it goes into production. That's Shengli's standard — if it doesn't survive her commute, it doesn't ship.
