Many aftermarket ear tips use silicone or foam, but dual-density tips—firmer inner core with softer outer skin—change acoustic impedance and create a more stable seal; this reduces low‑frequency roll-off and keeps bass consistent without increasing insertion depth, beneficial for listeners who want better passive isolation without altering fit.
We carry dual-density ear tips and can recommend sizes to preserve sound signature while improving comfort and seal.
