X5 (3rd Gen) Portable High-Resolution Audio Player (Black)
Product Description
The black X5 (3rd Gen) from FiiO is a portable high-resolution audio player and USB DAC for audio enthusiasts. The unit features an audiophile-grade architecture and premium components capable of playing files up to 32-bit/384 kHz in a variety of formats including native DSD, DXD, WAV, WMA, ALAC, FLAC, APE, AIFF, and more.
The X5 utilizes a pair of AKM AK4490EN DAC chips coupled to two dual-channel OPA1642 LPF chips and an OPA426 amplification chip for improved dynamic performance. Dual crystal oscillators ensure the lowest jitter and highest precision playback of music at any sample rate, reducing conversion artifacts.
The player offers a 3.5mm single-ended headphone output and a separate 3.5mm line out/digital (coaxial) output. A 2.5mm balanced headphone output lets you use the headphones of your choice. The third-edition X5 has 32GB of onboard memory, which can be augmented with two microSDXC card slots. The 3400mAh lithium-ion polymer battery provides up to 10 hours of playback under normal conditions. The Android-based user interface offers five unique themes, while the 2.4" IPS color touchscreen display offers easy navigation. The 10-band graphic EQ and the 120-step digital volume control allow for custom-tailored sound and levels.
The X5-III body is made from No. 180 zirconium sand with stainless steel accents, with a dot matrix pattern on the front and a star pattern on the back. The player ships with a USB cable, coaxial digital adapter cable, a clean case, a leatherette case, and a pre-applied tempered glass screen protector.
