Upping the ante to 2600 mAh, X3 provides those same 11 hours with greater power necessity. While it can play at normal volume for the same duration X1 can firmware upgrades are not prominent for it.

FiiO X3 comparison

Fiio X3

What makes X3 stand out, from the other entrant at least, is dual crystal oscillators that are dedicated to multiples of 44.1 and 48 kHz respectively, which ensures low jitter and highest precision for music playback at all rates and eliminates conversion artifacts. In more layman’s terms, this means it removes crisp sound as well as removes issues with sound quality that can come as a result of compressing or converting files. We shouldn’t neglect its DAC that, coupled with a low-pass filter, realizes extremely low noise and phase distortion.

The Winner: Fiio X3


Fiio X1

The light, small design of X1 makes it easy to store on your person when going outside. A mere 3.8 x 2.24 x 0.55 inches in size and 3.73 oz you can put it in even the smallest of pockets while using Bluetooth functionality for listening to music. The aesthetic of its classic design has a charm of its own as well as the effect on functionality with the functionality wheel.

Fiio X3

Being of slightly heavier size at 4.76 oz as well as a bigger frame with 3.8 x 2.27 x 0.63 inches body, X3 is at a rougher start although the difference isn’t all too noticeable. Aluminum alloy affords good durability just as it did to its predecessor. However, there is a difference in durability as it feels more metallic and its buttons are sturdier than that of X1. In practical application, this will reduce the chances of buttons going loose and breaking.

Despite some increase in weight, X3 offers better chassis for its sound.
