The Image S4i (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. A choice of four ear tip sizes allows for a perfect fit.
The headphones add a three button remote control with a built-in microphone for use with Apple's iPods and iOS devices. Users can play or pause music tracks, and answer and end incoming calls. The remote works with select iPods, iPhones, and all iPads.
Dual magnet driver technology delivers a wide frequency range while preserving dynamic detail. The Image S4i (II) features a standard 1/8" (3.5mm) stereo mini headphone jack, and a carry case is included for convenient storage, along with clothing clip for anchoring the remote.
