Sound Signature: warm, robust full-range response with extended lows

Drivers: twin dynamic drivers: parallel operation with no crossover

Nominated for a 2019 TEC Award, the D2 mounts twin full-range dynamic drivers in our unique Dynamic Resonance Chamber, operating in parallel for maximum headroom with no phase smearing or crossover distortion. D2 is the only custom dynamic IEM with our soft silicone earpieces for long-wearing comfort, perfect fit, maximum isolation, and secure seal.


"The soft silicone, coupled with the best seal possible, tons of headroom and that resonance secret sauce, make the D2 the first thing I reach for."

  • "Great bass response!"
  • "Smooth and totally natural high-mids and upper frequencies"
  • "Very comfortable, even after long listening periods”
