Much like its intriguing packaging, the design of the HMDX Jam is also non-conventional with its tapered looks and bright colors. In fact, it’s available in array of colors to choose from, but in our case, we dig its jam-like Blueberry color. Constructed out of some sturdy plastics, its metallic blueberry color complements its overall scheme – though, it does pack some weight to it. Sure, it’ll put a bulge in your pockets, but it’s compact enough to be tucked away discretely in a bag.
Initially, the HMDX Jam doesn’t appear to look like any other portable speaker, but upon looking at its top edge, its speaker grill tells us that it’s distinctively a speaker of some kind. Meanwhile, around the bottom rim of the speaker, we find buttons for pause/play, track forward, track reverse, auxiliary-in port, LED light, and microUSB port to charge its internal battery, which so happens to be rated for 4 hours of continuous playback. Finally, on the bottom edge, there's a switch that quickly powers it on or odd.
Placing it to the maximum volume level, our ears cringe because of the amount of crackling and distortion evidenced while listening to a song. However, after bringing it down a few levels, we’re able to better enjoy its pleasant output – though, it doesn’t quite deliver some of the deep bass tones we’d like. Nonetheless, there’s a tiny bit of vibration going on that exhibits some of its power. Overall, the quality is by far more enjoyable than dealing with the dainty speakers of most smartphones – plus, it’s nice that it boasts a unique design and decent audio quality to make it a pleasure to use. Attached with a $39.99 MSRP price, it isn’t that bad at all considering everything we’ve seen and experienced with it.
