Ultra-thin liquid silicone with a wide bore that stays out of the sound's way.
Liquid silicone rubber with walls just 0.45mm thin and a wide 5.5mm sound tube, sold as one set. Thin walls conform more gently than standard silicone; the wide bore avoids choking the nozzle — KZ positions them to reduce sibilance and preserve clarity.
0.45mm ultra-thin walls: Flexes to your canal with less pressure than standard tips.
Wide 5.5mm bore: A larger opening than typical stock tips.
KZ's size range: Per KZ: S 10mm, M 12mm, L 13mm outer diameters across the LS01 line.
Who it's for
Listeners who find standard silicone fatiguing, and wide-bore fans chasing an airier presentation.
The honest trade-offs
Thin walls grip the nozzle less firmly — check fit when removing your IEMs. Fits 5.0–6.5mm nozzles; measure yours if unsure.
