Sorry, This product is no longer available



It's not exactly an easy task to create a pair of headphones that are able to extract the full dynamic potential of a recording, while keeping them portable enough to put in your pocket. However, Onkyo, and their 65 years experience in hi-fi audio, have stepped up to the challenge with the development of an entirely new headphone sound.

The IE-HF300 headphones make use a of a large transducer, low in impedance. These headphones reach deep in to the mix and balance a velvet-smooth bass with an open and natural mid-range. A sturdy aluminium and ABS resin build provides the necessary rigidity to tame resonance and distortion. Crisp-clear sound is thanks to the audiophile approved, super-conductive copper cable, which is wrapped in a transparent elastomer insulation which minimizes touch noise

Detachable gold-plated MMCX connectors create an easy cable replacement process, should accidental damage occur. Tempered with a burnished black aluminium finish, these highly comfortable and stylish in-ear monitors are prepared and ready to bring your music to life.

Different colour replacement cables available, phone in-store on 01432 354921 or email for details.
