The Fiio E1 Headphone Amplifier (Black) is designed to work with the Apple iPod and iPhone. It features innovative in-line remote control functions and an integrated, high-quality Texas Instruments IC headphone amplifier. The E1 is cleverly designed to use the line-out signal from the Apple 30-pin docking port. This provides better sound quality and makes the amp able to drive high impedance or low sensitivity headphones - giving you the clarity and punch to make your music sound alive and vibrant. Plus, with the in-line control functions, you can easily operate the playback of your iPod or iPhone from the E1 itself.
Designed and compatible with all generations and all versions of the Apple iPod nano, iPod touch, iPod video and iPhone
Improves the sound quality by using the line out feature from the iPod/iPhone charge/sync docking port
