Electronics Wow, how tech has changed. I remember, many years ago, when I had been doing some traveling… As I was getting ready to go away with my girlfriend of the time, we decided that we really wanted to have music with us. So I actually went out and bought speakers that fit into a case that was probably almost 12” x 12” x 12”. I's Why's Small and lightweight; easily fits in a suitcase, backpack, or briefcasePowerful- these really fill a room with soundMultiple connection options- Bluetooth and 3.5mm audio inSpeaker & built-in microphone can be used for phone callsOne charge lasts about 5 hours of play timeNow, the sound out of the speakers was just fantastic, but the thing probably weighed 15 pounds. Then, after using that for a while, we decided that we wanted to be able to use it when we weren’t near an outlet. The battery pack was also expensive–I don’t remember how much–but it was heavy as well.But that was then, and this is now. I still want a speaker that I can take with me that has good sound but that I really wouldn’t notice in my backpack or suitcase. I tried a couple of different models, and decided on the Oontz Curve. I’m not sure it sounds as good as those speakers from all those years ago, but it’s a heck of a lot more convenient. And this little speaker can definitely fill a hotel room with a lot of sound, probably more than you can get away with in a hotel room. The other way I really like to use this speaker is to sit it on top of an Amazon Echo Dot. So, let’s say you don’t want to spend the money on an Amazon Echo. The Echo Dot is just an Amazon Echo with the hundred-dollar speaker chopped off and replaced by an inexpensive speaker. Pop an Oontz Curve. on to your Dot, and you have a really nice compromise. All of the Amazon Echo functionality and much better sound than you get out of an Echo Dot. So now, let me tell you some things about this speaker. First of all, its dimensions are under three inches. It has a 3.5 mm jack for plugging different source devices, like the Amazon Echo Dot, in. It’s got a mini USB jack to charge it up or just to run off of. The Bluetooth range is about 30 feet, so you can stream music from your phone to the Oontz Curve while your phone is still in your pocket. And it’ll run for about five hours on a charge. There are many uses for such a compact, portable speaker—for business as well as pleasure.Finally, I want you all to understand where I am coming from with this product. This is not the best portable speaker in the world. But, in my opinion, for its portability, it has very good sound and is very convenient to throw in your backpack or suitcase. It solves the problem of wanting portable music incredibly well, if size and weight are the main decision factors—and, of course, sound.
