Perfect For the Active Music Lover

Combining portability, aesthetics, and comfort, the IE-FC300 In-Ear Headphones offer an engaging listening experience on the go. Detachable flat elastomer cable with gold-plated MMCX connectors ensures a noise-free link to your media player, and best of all, won’t tangle when stored in your bag. With over 65 years of audio experience, Onkyo headphones deliver the sort of full-bodied sound you’d expect from a high-end stereo setup in a pair of portable IEMs. Noted for throwing a pleasingly deep soundstage, the newly designed 14.3 mm (9/16") drivers produce clear mids, crisp highs, and punchy bass that enriches all kinds of music. Form-fitting earpads are angled comfortably to provide a good seal against ambient noise, and they won’t cause fatigue during longer listening sessions.

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. The tuning of the IE-FC300s is refined and perfected to produce deep, tuneful bass that doesn’t overwhelm the middle frequency band.

High-Performance Dynamic Drivers

The IE-FC300s 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.

Detachable Tangle-Free Cable

The cable’s flat cross-section not only keeps the conductive core insulated from noisy knocks and bumps; it also resists tangling when not in use. 

Detachable MMCX connectors allow you to upgrade or replace the cable quickly and easily.

Rugged Construction

Onkyo protects your investment with the use of tough, impact-resistant materials. All cable connectors are gold plated to preserve signal integrity and resist the effects of corrosion, extending the life of your headphones.

Carrying case included.

Comfortable for Long Listening Sessions

The nozzle section on the IE-FC300s is angled to provide optimum comfort and a secure fit. Ergonomic soft-touch earpads provide a firm, comfortable seal against ambient noise, and won’t fatigue during longer sessions. Running for a train or putting your feet up at home, you’ll hardly know you're wearing them.
