With the ZEN Air CAN, you can get the most out of your headphones. With plenty of power and top-notch features, the amplifier from iFi Audio is the best choice if you want to enjoy balanced, rich, and voluminous sound. Connect your PC, CD/DVD player, TV, streamer, laptop, smartphone, tablet, or gaming console to the two RCA inputs or the 3.5 mm jack on the back of the ZEN Air CAN, and be surprised by how many beats, basses, and sounds you have never noticed before. On the front of the ZEN Air CAN, there is a 6.3 mm and a symmetrical 4.4 mm socket for your headphones. Using the gain switch on the ZEN Air CAN, you can select the amplification that best suits your headphones. The volume can be precisely adjusted using the dial. With the ZEN Air CAN, you finally unlock the full potential of your headphones. This experience is made possible in part by the XBass technology. You can adjust the bass according to the headphones you are using and your personal taste, enjoying rich, deep tones. Additionally, the XSpace function allows you to add more spaciousness—almost like at a live concert. Experience the sound of your headphones like never before.
