The Image S4 (II) from Klipsch is a pair of in-ear headphones that not only deliver full range audio with deep bass, but also provides a level of isolation from external noises. Unlike circular-shaped ear tips which may not fit properly, the headphones utilize an oval ear tip design that fits the ear cavity more comfortably. Four ear tip sizes allow for a perfect fit.
Dual magnet driver technology delivers a wide frequency range while preserving dynamic detail. The Image S4 (II) works with virtually any device that features a standard 1/8" (3.5mm) stereo mini headphone jack, and a carry case is included for convenient storage.
