The FiiO L3 is designed with a 3.5mm stereo jack to Apple"s dock connector, enabling output of high quality line-level audio from iPod, iPhone, and iPad that can be sent to portable audio equipment such as headphone amplifiers and power amplifiers. Designed with high-quality materials, the L3 isolates the audio signal from interference to deliver cleaner and more accurate sound from your iPod/iPhone/iPad. The L3 employs the new HPC-22W cable with ultra-fine PCOCC-A conductors for its exceptional signal transmission property and usability. Twenty strands of 80μm PCOCC-A wire are unified into a bundle and three bundles are grouped as a conductor that is geometrically stable. This construction method ensures uniformity of wire structure, eliminates internal gaps, and prevents deformation of wire strands. Each conductor in the HPC-22W is jacketed with 0.18mm PFA (Teflon), a material selected for its outstanding electrical and transmission characteristics. The shield/ground consists of 53 strands of 0.12μm PCOCC-A wire, with cotton rope filling the internal space and providing additional tensil strenth. The outer jacket is made of TPE olefinic elastomer.Feature Highlights - Shielded construction provides maximum isolation from interference - Pure copper conductors for better audio clarity and a more natural-sounding midrange - High quality durable connectors for precise contact and signal integrity - Supports standard dock profile on iPod, iPhone, and iPad. Does not support Shuffle.
