Crucially, Spotify, Tidal, and Apple Music work with the X7MkII, though the latter had to be side-loaded and ran with frequent hiccups. The Google Play Store is included, and many apps run just fine on the X7MkII. Still, we found the experience acceptable and certainly faster than other DAPs we’ve tried. Don’t expect current-generation smartphone performance from the X7MkII - in Android mode, this device is not as snappy as iOS 11 and Android O, and we did experience occasional unresponsiveness and stuttering. The X7MkII features 2 GB of RAM and a Rockchip RK3188, 1.4 Ghz quad-core CPU running on highly-customized build of Android 5.1.1. In our testing, we found that the X7MkII’s hardware buttons are sometimes more responsive than the touchscreen and, though not necessarily a problem, the volume wheel can feel a little ineffectual when scrolling through the X7MkII’s 120 volume steps. In a market full of thin, rounded slabs of tech, we find the X7MkII’s hardware design distinct and refreshing clearly Fiio has put significant thought into its design language. The X7MkII’s dedicated buttons for track play/pause, forward/back, and volume have nice tactile feel, activate with positive clicks, and can be individually disabled if desired. When connected to a Mac or PC, the X7MkII can use its microUSB port to function as a USB DAC (driver required for PC). On the right side are two microSD slots which allow for expansion of the onboard 64 GB of memory to an additional 512 GB. There’s a ton of functionality just in the hardware - next to the X7MkII’s recessed power button is triple-function 3.5mm coaxial/optical/line out jack. Though a clear TPU case and red-stitched faux leather case are in the box (along with other accessories), the X7MkII really should be experienced directly in the hand - its sandblasted aluminum chassis, punctuated with polished chamfering, feels solid and substantial. It appears to be designed for use in the left hand, with all the hardware controls located along an angled surface on one side of the device. The X7MkII is a beefy aluminum rectangle - it looks like a smartphone from an alternate timeline where we weren’t collectively obsessed with ‘thinness.’ It’s heavier than the iPhone X by 38 grams, but lighter than it looks.
