Customer Benefits

Headphone mixes often fail to translate because the headphone itself colours the picture. The H715 Reference starts from a wide, low-distortion response from 9 Hz to 40 kHz, so low end and top end are both visible when you make decisions. The Sonnox-built Headphone Utility Plug-In sits on your DAW’s master or monitoring channel, while ListenHub brings calibration, metering and A/B referencing to the whole system. The open-back design keeps long mixing and mastering sessions natural, and the replaceable ear pads, headband pad and detachable cables keep the headphone in service for years.
