Push-Pull Drivers for Precise Sound

If an ultra-precise audio experience is what you’re after, the Audio-Technica ATH-CKR100IS IEMs are sure to please. Their unique dual-phase push-pull system works like this: two facing 13-millimeter drivers generate phase-aligned audio signals, which are then mixed to compensate for each driver’s inefficiencies. This system results in a spacious, expansive, and detailed sound across a wide frequency range to complement every genre of music. And Audio-Technica’s attention to detail doesn’t end there. The detachable cables use the company’s newly developed A2DC connectors, featuring two separate star-quad cables—one for the left channel and one for the right—to improve isolation from external noise and channel crosstalk.

“This Is How an IEM Should Sound”

In a 4.5-star review, Head-Fi user iems0nly says, “Let me tell you why these are the best! Bass, resolution, vocals. They are simply amazing, and most satisfying. No other IEM gave me this perfect combination of the three most important parameters that make an IEM great. Just perfect. No sibilance at all, tight bass, with perfect decay, mesmerizing vocals, perfect color. This is how an IEM should sound.”
