IE-HF300, 14.3 mm, 15 Hz-22 kHz, 30 mW, 105 dB/mW, 32 Ohms, 1.2 m, 12 g, Black / Silver Cable
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.
<b>High Purity Copper-Core Cable for Pure Sound</b>
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.
<b>High-Performance Dynamic Drivers</b>
The IE-HF300s 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.
<b>Comfortable for Long Listening Sessions</b>
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.
<b>Deep,Well-Controlled Bass Performance</b>
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.
<b>Rugged Construction</b>
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.
<b>HF Player: Precision EQ App for iOS</b>
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.
