Cans2Conesv4 is a headphone-to-speaker emulator designed to improve mix decisions when monitoring through headphones. It reduces the exaggerated stereo effect typical of headphone listening by applying Interaural Time and Amplitude Difference cues, creating an authentic sense of space that simulates the distance and placement of speakers in a treated room. Unlike simple stereo width adjustments, this plugin provides a true perception of speaker size and positioning, making headphone monitoring more natural and accurate.

The plugin features a Dynamic De-Compression control that addresses the compressed, 'in your head' sound caused by the close proximity of headphone drivers to the ears. Users can choose from three preset speaker configurations—Near-field, Mid-field, and Far-field—tailored to common speaker sizes and placements. Additionally, a subwoofer control extends the frequency response to cover the full bandwidth, while a Distance slider allows custom positioning from 0.5 to 15 feet, offering flexibility to match various listening environments.

Cans2Conesv4 is a 64-bit plugin compatible with multiple formats including VST2, VST3, AAX, and AU, supporting Windows 8 and later as well as Mac OS 10.11 and newer on both Intel and Apple Silicon processors. Its broad compatibility ensures integration into most digital audio workstations. Users can try the plugin with a free 14-day trial available for download, allowing producers and engineers to experience improved headphone monitoring firsthand.
