Sound Performance: 1, first to make clear the overall style of IE900 sound: This is an excellent detail performance of the ear buds, sound is quite balanced, medium, in full compliance with Hifi high-fidelity definition. Audition Equipment COLLOCATION: Cayin n 8 player, single port, medium gain transistor output. Comparison earplugs: IE300, Cheranto. The IE900 is arguably the best in Sennheiser’s line of earbuds, with the early IE8 having plenty of high frequency energy, but not enough detail and stiffness; the IE300 being soft and lacking in detail; and the Pro series being relatively good. IE900 high-frequency details rich, delicate, energy sense of moderate, for the instrumental sense of reality, texture performance excellent, with a high degree of transparency. The medium and high frequency details of the IE900 are significantly more detailed than those of the Champs Elysees, which some might argue isn’t a particularly detailed style in the first place, but I usually use the Champs Elysees as a reference point for evaluating portable equipment/earplugs. A unified standard is convenient for everyone to cross reference. IE900 medium density moderate, still have excellent detail reduction ability, bring the human voice very good realistic feeling, the human voice is relatively heavy music flavor with a little bit of dye, IE300 human voice is more fuzzy some, dye more obvious. IE900 has good low frequency control, no loose problems, and low frequency can be extended to very low frequency, although the overall low frequency does not feel very much, but some very deep low frequency can be restored, it’s similar to listening to a large-diameter Woofer, a feeling rarely seen in earplugs before. Compared to IE8, IE300 low-frequency control is weak, the sense of quantity is more, some of the style is a radical change. IE900’s low-frequency extension is significantly better than the Charan Diagram, the difference in control is not significant.
