The IE-CTI300: MeetYour New Best Friend

Discover the award-winning sound of Onkyo in-ear headphones with the added convenience of an inline cable controller for Apple devices. Now you can skip tracks, make volume adjustments, and accept or reject calls at the touch of a button on the cable. As a premium hi-fi product, the detachable cable features an oxygen-free 6N copper core sealed in transparent elastomer to reduce tangles and touch noise. Large 14.3 mm (9/16 ̋) dynamic drivers reproduce an exceptionally wide range of frequencies with brilliantly clear mid-range performance. Bass is punchy and musical while leaving plenty of headroom for the treble to breathe. Light, stylish, and comfortable to wear when you’re out and about, the IE-CTI300s are the perfect high-fidelity partner for your iPod® or iOS device.

Seamless Control of Apple Devices

From the 160 GB iPod classic® favored by committed music collectors to the endless entertainment possibilities of iPhone® and iPad®, you’ll find it easier to cue and control your media with the IE-CTI300. Inline controls work with all Apple devices to make on-the-fly adjustments easier. If a call comes in, just tap a button on the control.Your music will mute automatically and you can start talking straight away, with your caller’s voice coming clean and clear through the earphones.

Detachable Cable with Inline Controls

To strike a balance between sound quality and convenience, your included cable features an oxygen-free 6N copper core that provides close to perfect conductivity, which equals super-clean sound. Encased in a transparent elastomer coating to minimize touch noise, this audiophile-grade cable incorporates an iOS-Certified inline control with mic, allowing users of Apple devices to skip tracks, adjust the volume, and take or reject phone calls at the touch of a button. Gold-plated MMCX connectors , meanwhile, are detachable and let you swap out the cable if you’re unlucky enough to damage it. Note: Some smartphone cases including Apple iPhone 5s/5c cases may prevent a proper cable connection.

High Purity Copper-Core Cable for Pure Sound

The headphone's cable is of critical importance to its sound quality. The IE-CTI300 comes with a 6N oxygen-free copper cable, which delivers almost zero resistance for superior sound.

Insulating the core is a tough and flexible elastomer sheath that minimizes touch noise and ensures the best possible conductivity. It also resists tangling. As with all Onkyo headphones, it's also detachable for easy replacement. View cable close-up.

Deep,Well-Controlled Bass Performance

Experienced headphone users agree that bass response isn't a question of quantity, but quality. Drowning in poorly defined bass does no music any favors, whereas well-balanced low frequencies add weight and dynamism to all kinds of music. Onkyo's engineers spent long hours perfecting the tuning of the IE-CTI300s to produce deep, tuneful bass that doesn't overwhelm the middle frequency band.

High-Performance Dynamic Drivers

The IE-CTI300s feature an uncommonly large 14.3 mm (9/16"̋) dynamic or moving-coil-type transducer. The design is noted for its durability, accuracy, and ability to reproduce a wide frequency bandwidth, and it's perfected here in a particularly natural-sounding custom driver. Durable aluminum/ABS resin housing provides exceptional rigidity, reducing unwanted vibration. These drivers are sympathetic to compressed audio formats without sacrificing sensitivity for lossless and high-resolution playback.

Running for a train or putting your feet up at home, you'll hardly know you're wearing them.
