Sorry, This product is no longer available



The IE-CTI300 brings the outstanding, award winning level of Onkyo sound quality to a compact, convenient and personal listening experience. Innovative features like the integrated microphone/control allows you skip tracks and play/pause, or accept/reject calls without needing to pull your device out of your pocket. The IE-CTI300 is a premium, high fidelity product, so every essence of its construction retains an Onkyo-famous level of quality throughout. 

The detachable cable features an oxygen-free 6N copper core, sealed within a transparent elastomer, making it not only a lot harder to accidentally tangle - but also a lot harder for external interferences to effect the sound being passed through the cable. The drivers of the IE-CTI300 are 14.3mm in size and are capable of reproducing a wide range of frequencies to an astounding level of accuracy, projected across a vast sound stage with pin-point imaging.
