The FiiO L2 is designed with two 3.5mm stereo jacks for connecting portable audio equipment such as headphone amplifiers and power amplifiers to any audio source with a 3.5mm output jack. Designed with high-quality materials, the L2 isolates the audio signal from interference to deliver cleaner and more accurate sound.
The L2 employs the HPC-22W cable with ultra-fine PCOCC-A conductors for its exceptional signal transmission property and usability. Rather than twisting whole wires, twenty strands of 80?m 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. Furthermore, its total conductive area is equivalent to AWG-22, which is three times larger than regular audio cables. 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 0.12?m PCOCC-A wire, with cotton rope filling the internal space and providing additional tensil strenth. The outer jacket is made of TPE olefinic elastomer, making for a tough, durable yet overall flexible cable.
