IE 300 – That's not the latest version of Internet Explorer but Sennheiser's new IEM [€299] built around a 7mm dynamic driver using a polymer membrane for claimed distortion of just 0.08% THD. An internal chamber is tuned to cancel airflow disturbances. The MMCX- detachable para-aramid reinforced cable loom terminates in 3.5mm but a symmetrical cable with 2.5mm or 4.4mm plug is available for a surcharge. Claimed bandwidth is 6Hz – 20'000Hz with a 16Ω impedance.
