The first thing I like about it, is its design, the rubber case that prevents slips and allows to place the unit in different positions, besides encasing the mesh metal LED light-covered speaker.The sound is surprising good, and when listening to the music stored in my smartphone, it announces an incoming call if I receive one. Then, I have the option to answering or not, by pressing the play/pause button, and talking over the speakerphone. It takes some getting used to answer calls, but it comes handy, if I don't want to use my headset.The JAM Trance Plus weights very little (about one pound and a half) and it can be easily carried around. It has embedded rubber buttons on a side, or the front, or top, or bottom. All depending of how one places it, vertical or horizontally. It takes little space, but it delivers quality sounds as well as any larger Bluetooth speakers do.The rubber buttons in front of it, are its control panel for the sound and mobile features, and there are more buttons on a side for the lights’ settings. Also, there is a covered partition that houses three ports: the USB one for charging, an auxiliary audio input 3.5mm (no audio cable is included) and the Language selector port. In there is also a tiny LED battery charging indicator, and what it looks like a resetting hole, but I didn’t find any information about it. I’m just mentioning in case you notice, and wonder what’s could that be.What I like about it the most, is how easy is to pair it with other devices, and that it would resume the pairing very quickly. I drop my phone while carrying a bunch of stuff, and the phone’s battery got loose. But as soon as put the phone together and turned it on, I heard the JAM Trance saying ‘pairing up’, and there it was, paired in seconds. None of my others speakers, or headsets had done such a thing before.The JAM Trance Plus’s voice will tell together with different light colors what’s doing. For example, while powering on it lights up multicolor all over, at ready to pair is green, and paired is blue. The lights tell you together with the voice what is doing, and if you decide to turn the voice off, it will let you know what’s doing using its lighting.And the lights can be easily adjusted, or totally turn off. There are so many ways to customize the light show, (36 LED light programs which synchronize with the music being reproduce) that it should never bother, or bored us at all.It comes with a very short Micro USB cable for charging, so I’m using a longer one that I already had.It also includes a clip-like thing, which is a Language selector pin, to be used for selecting among a few languages for the device’s voice, or not voice at all, and just a tone. The pin is used by pushing a little hole in the control panel and while doing so, toggling until finding the desired language. I uploaded a few pictures showing some details of it.In all, I like how it works, and I like that even in the dark one can learn what to push because the embedded rubber buttons could be easily memorized. The rechargeable Lithium-ion battery charges in three hours for up to ten hours of use, even with little charge, the speakers always sound great, but it will light up all red to warn of low battery charge.I’ve never been a fan of multi-lights gadgets, but I like this speaker this very much.
