    ▶ Crossfeed – We’d all love to listen to music on great speakers. But — most of the time — modern life calls for headphones. CanOpener’s unique “Crossfeed” helps you recreate, on headphones, the rich sonic experience of listening on high-end speakers.

    ▶ Equalizer – Dial in some more clarity, scoop the mids, boost or cut the bass. CanOpener offers flexible tone shaping with gorgeous, touchable equalizer options.

    ▶ Dosimeter and loudness metering – CanOpener can measure precisely how loud you are listening, helping you monitor your listening habits and protect your hearing.
