The IE-HF300: Hi-Fi Earbuds that Let Your Music Off the Leash

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.

High Purity Copper-Core Cable for Pure Sound

The headphone's cable is of critical importance to its sound quality. The IE-HF300 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. 

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. 

High-Performance Dynamic Drivers

The IE-HF300s feature an uncommonly large 14.3 mm (9/16"Ì‹) 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.

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-HF300 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.

HF Player: Precision EQ App for iOS

Free HF Player includes 16,000-BAND FIR equalizer with memory presets. The in-app purchase upgrade enables 192 kHz/24-BIT DSD, FLAC, WAV playback. The phase-linear FIR equalizer offers 16,384 discrete bands of equalization with zero loss in audio quality. Simply shape your desired frequency curve with a finger on the touchscreen — manipulate bass, mid-bass, mid-range, and treble response. Presets may be created to suit a particular musical genre, artist, album, or pair of headphones, and can be saved, swapped, and loaded in moments.
