ONKYO IE-HF300

Let Your Music Off the Leash
Creating headphones that can extract the full dynamic potential in a recording—while remaining portable enough to stick in your back pocket—is no easy task. Yet Onkyo, a company with more than 65 years’ experience in hi-fi audio, has managed to do just that with the development of an all-new headphone sound. Featuring a large, low-impedance transducer, these headphones reach deep into the mix, balancing silky smooth bass with an open and natural mid-range. Tough aluminum and ABS resin hybrid construction helps to provide the necessary rigidity to tame resonance and distortion. Crystal-clear audio comes courtesy of an audiophile-grade, super-conductive copper cable wrapped in transparent elastomer insulation to minimize touch noise. Detachable gold-plated MMCX connectors allow easy cable replacement in case of accidental damage. Available in a burnished black aluminum finish, these comfortable and stylish IEMs are ready to make your music come alive.

High-Purity Detachable Copper-Core Cable
Your headphone cable is of critical importance to sound quality. Good cable should minimize touch noise and ensure the best possible conductivity. The IE-HF300s come with a detachable 6N oxygen-free copper cable, which delivers almost zero resistance for superior sound. Insulating the core is a tough and flexible elastomer sheath that won’t easily tangle. Unlike other cables, which aren’t designed for pure audio, it’s a one-piece type with no extensions or inline controls to get snagged on clothing or bags.
Note: Some smartphone cases may prevent a proper cable connection.

High-Performance Dynamic Drivers
The IE-HF300s feature a large (14.3 mm) 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.

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-HF300s to produce deep, tuneful bass that doesn’t overwhelm the middle frequency band.

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.
Comfort for Long Listening Sessions
The nozzle section on the IE-HF300s 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.
