The release of FiiO X3's new firmware (FW2.1)—Nov 20th 2013
X3 Firmware version FW2.1 fixed the following issues in version FW2.05:
1. Fixed issue with playback of 192kHz tracks where repeated plugging
and unplugging of headphones may cause the sound to change pitch.
2. Fixed issue where the song's progress bar does not move when fast forwarding.
3. Fixed issue where X3 produces "pop" sounds when used as USB DAC with certain computers.
(glitches may still occur with improper computer configuration)
4. Improved file sorting in browse mode, being now compatible with songs exported from iTunes.
The zip file includes FW2.1, E-manual, DAC driver and its installation manual.
Note: For users with X3 updated to FW2.05 and installed the device driver, there is NO need to install it once again.
