Onkyo IE-HF300 in-ear headphones extract the full dynamic potential from audio recordings & are portable enough to stick in your back pocket. Featuring a large, low-impedance transducer, these headphones balance silky smooth bass with an open and natural mid-range. Tough aluminum and ABS resin hybrid construction provides the necessary rigidity to tame resonance and minimize 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.
