K701 Open-Back Reference Studio Headphones

The AKG K701 is an open-back reference headphone built around flat-wire driver technology, a design AKG pioneered specifically to give each instrument in a mix its own precise, identifiable place in the sound stage. The result is a wide, spacious sound with brilliant highs and a punchy, well-defined bass, backed by a frequency response of 10 Hz to 39,800 Hz and a sensitivity of 105 dB SPL/V. As an open-back design, the K701 favors imaging and airiness over noise isolation, making it a headphone suited to a controlled listening environment rather than a busy studio floor. A fixed 3 meter cable terminates in a 3.5mm plug with a gold-plated 6.3mm screw-on adapter, covering both mobile devices and full-size studio gear. At 235 grams, the K701 stays light enough for long analytical listening sessions, whether the goal is evaluating a mix for accuracy or simply listening for enjoyment. Mixing and mastering engineers who need precise stereo imaging over raw isolation get a headphone engineered around that exact tradeoff.
