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 its 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.
Deep, Well-Controlled Bass Performance
Experienced headphone users agree that bass response isnt 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. Onkyos engineers spent long hours perfecting the tuning of the IE-FC300s to produce deep, tuneful bass that doesnt overwhelm the middle frequency band.
Comfort 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 wont fatigue during longer sessions. Running for a train or putting your feet up at home, youll hardly know youre wearing them.
Detachable Tangle-Free Cable
Few things are as frustrating as having to unpick a tangled mess of cable when you should be listening to music. The cables 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
High portability inevitably means a greater risk of bumps, bangs, and knocks. 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.
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, wont tangle when stored in your bag. Onkyo brought 65-plus years audio experience to bear in designing these headphones, aiming to deliver the sort of full-bodied sound youd 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 to enrich all kinds of music. Form-fitting earpads are angled comfortably to provide a good seal against ambient noise, and wont cause fatigue during longer listening sessions. An ideal launching pad into the world of personal hi-fi, these stylish headphones are perfect for the active music lover.
