There is also a possibility to change the themes and make themes on your own, and it's not hard at all, several videos about it on YouTube and several posts about it here on Head-Fi. If you have a small size album art or no album art at all, the X3 is very fast and responsive.

It's decently fast and responsive with an exception when you have a huge size album art on your songs, then there is a delay in UI when you play or change the song it starts playing in an instant, but the screen is frozen for a second or two till it shows the position of the song, it's not a major issue but just to note it. The user interface on X3 is good and it couldn't be much better if you see that it doesn't have a touch screen and/or volume wheel.

It's also decently light at 122 grams, which might surprise some because of metal finish - it looks heavier than it is. It has a decent battery of 3100 mAh, and while they claim it will last ~10 hours, I get around 7-8 from it, though I'm crazy track swapper so the screen is on a lot more than an average person would have. The player is built with the combination of metal front and back and good plastic around, it looks and feels nice. On the left side there is a MicroSD card slot (you don't get a MicroSD card with the player), and the player itself is equipped with just 8 GB of memory, but who cares about that when you can get 128 GB and if not now then soon 256 GB SD card. On the right side there is a "hold" switch that is used to block other buttons to be mistakenly pressed, though I haven't used it once since the buttons are not that sensitive, and it will never happen that you mistakenly press a button, but still there it is. It has coax out, line out and 3.5 mm headphone jack as well as a micro USB port for charging, using as an external DAC or transferring music from PC.

It is built very nicely, has some retro touch to it since it doesn't have any wheels or touch screen, just buttons and normal, not so good, screen (but it does the job just fine). FiiO X3 comes in a nice box with an adapter and micro USB cable, as well as a nice soft silicone sleeve to protect the player.
