It's a no-frills music player that supports MP3, WMA, FLAC, WAV and a handful of other file types, with the d-pad used to control the volume (up and down) and track progression (left and right). The Dingoo handles each of its more pedestrian functions ably. Again, certainly not a wholly unforgivable design flaw, but a genuine annoyance. Both are recessed in near identical holes and, due to the system's habit of sporadic lock-ups, I've found myself mistakenly shoving a paperclip into my mic rather than the reset trigger on a number of occasions. You see, nestled there below its exquisite d-pad lies the a320's reset button and microphone.

The left side of the unit, however, leads me to my first legitimate beef. It's certainly not a major complaint, but it's an erratic behavior worth noting. Sometimes I find myself holding the switch for several seconds before the a320 powers on, and other times the merest flick will turn it on or off. Originally I was under the impression that one simply needed to 'flick' the button upward to power the device on and hold it to shut it off, but after extensive testing I have determined that the switch is just a little finicky. The hold function was another interesting perk, but even after using the device for weeks I'm still a little unclear on the functional lean of the power slider. The right side of the a320 boasts a headphone output РІР‚вЂњ positioned in such a way as to allow the user to slip the unit easily into a pocket for some on-the-go listening РІР‚вЂњ and the power/hold switch. It's a bit of an odd choice to supplement the a320's 4GB of on-board storage given the prevalence of its smaller cousin, but thankfully I had a micro-to-miniSD adapter that proved indispensable for this particular technological emergency. Positioned between them is an AV Out port, a mini USB input for charging and file transfer and a miniSD expansion slot. Plus, the fact that they are embellished at all and not simply holes in the plastic frame is another pleasant surprise.

These speakers are by no means what one might call 'high-fidelity,' but the sound quality is more than acceptable. The bottom of the system is home to a pair of metal-grilled speakers. Even the L and R shoulder buttons that rest atop the unit, which are in truth little more than glorified cousins of the Select and Start nubs, have a proper pop that belies their diminutive size. The a320 also ships with a screen cover that protects the entire face of the handheld from scratches, although it does gather more than its fair share of fingerprint grime. Likewise, its 2.8 inch LCD offers a crisp picture, an incremental backlight and far less glare than one might imagine. Said face buttons (A,B, X and Y) and the system's d-pad have a good, hearty feel and solid, springy response that's rather unexpected for a device of this type, as do the intuitively positioned Select and Start buttons.

In truth, the system is slightly larger than the Micro and has extra face buttons, but it's easy to confuse the two at a glance. The Dingoo's most obvious physical feature is its uncanny resemblance to Nintendo's Gameboy Micro.
