iFi Audio iCAN Headphone Amplifier-Express shipping Creating a one-box-fits-all-headphones amplifier was a challenge. Thats because headphones are a diverse lot. So when our engineers designed the new iCAN, they didnt start with the amplifier; they started with the headphones. Unlike traditional headphone amplifiers, the design of the iCAN is based on the whole gamut of headphones. This atypical approach has bestowed upon the iCAN a unique ability to realise the full potential of each and every headphone. First and foremost, it was designed for the finest sound quality. With XBass you hear deeper, richer and cleaner bass. The 3D Holographic Sound system creates headphone-based music that is free-flowing rather than restricted.
