This is a good solid speaker for the cost. Water resistant, very long battery life and decent sound. I also have the Oontz Angle Ultra that I purchased in 2014, and it still works perfectly. This is a slightly larger version of that and has a few more features, but is basically the same.Very easy to use thru bluetooth or wired (headphone jack). With two speakers you can set them up in stereo, which works well and has improved sound over the single unit. Documentation is not great on this, but it's really pretty easy. A google search will get you going in less than a few minutes and you won't have to search it again. The only downside of having two speakers in stereo is that only the right channel speaker or source can be used to to change whatever is playing. A minor annoyance.Wireless range is of course limited by bluetooth, but they work well within about 20' to 30' of the source as long as it's not too obstructed, standard bluetooth stuff. I don't think you can get the 100' range stated unless it's clear.At higher volumes, they can get distorted, esp when playing anything with heavier bass. With moderate volume, the sound is pretty good, and I've seen over 12 hours of battery life, so 20 hours could be possible. If the battery does die, you can continue to use it by using a micro usb charge cord (provided) and cell phone charger (or computer).I can't attest to durability, as I really try and make a point of not dropping or abusing them. They have had a few bumps here and there, and maybe fallen off the steps onto the patio (about a foot drop), but have held up. They have also had some rain hit them, but I usually take them in once it starts. Take care of your equipment and it should last. :) My other unit has lasted for over 6 years, is still in use.They are not Sonos level sound quality, but also don't cost anywhere near that.Recommended if you want to play music anywhere, at reasonable cost. With their smaller profile and weight, these are easy to manage. They are not going to thump or be loud enough to blast, but you can have music anywhere and it's an improvement over most phones or tablets.

outstanding product. Volume, Trebel and bass knobs on front of Right Speaker easily accessible. Let's face it the Bass isn't like having a Sub but its still good. Allman Brothers at the Fillmore East sounds terrific. No complaints at all. For $ 70.00 you can't go wrong here.

i didn't think the sound would be great, but these little guys work just fine.

I bought them for my daughter and she is happy with them.

I bought these to use with my multitrack recorder, but they kick ass as computer speakers also!

I really love these little JBL speakers because they sound great for their size. I bought a second one so that I can get stereo when combined with my first one. If you download the JBL app on you device it is really easy to use and you can choose between stereo or not so that you can share speakers in different rooms. They are very small speakers but yet they produce some amount of base. The battery life is just fantastic. I listen to mine probably eight hours a week but only recharge it once every two months or so.

Returnable or not, these speakers perform exceptionally well on a small desk. I don't even feel myself wishing I had a sub-woofer, You can's go wrong with these speakers at this price!-------------------------------------Update: Dec 26,2017It's been about two years since I purchased the original pair of these speakers. Since I first purchased them, we've moved into a new house and I got to design my music studio from the ground up. In my new room, I have two DAW desks which greatly simplifies my workflow. I use the smaller desk as an audio scratchpad. It is simple to operate when I get inspired. I've had the original pair of these speakers sitting on that desk for about four months now. They fill a major void in modern DAWs, in that I can plug them into the computer's audio jack to listen to Windows system sounds, YouTube videos, etc., and keep them independent from the DAW's audio path (which uses an audio interface to drive the main nearfield monitors). Over the time I've had them, I've gotten to love their sound. So much so, that sometimes I just use them in lieu of the KRK Rokit 5s (the main monitors for that system) through ASIO4ALL. My main production desk has been a project in the making since we moved into the new house, and I just finalized it this week. When I sat down and started using it, I realized that one thing I overlooked was speakers to support Windows audio without sending it through my audio interface. So, I borrowed the T20s from the smaller desk and moved them to the new main desk. I also removed the grill covers so that the speakers can be seen. I'm a KRK fanboy and have KRK V6s as my main monitors (almost 18 years) and I love the yellow poly-cones of KRK speakers. I knew I needed a set of "computer speakers" to complete the system, and I'm here at Amazon to buy another set of T20s. Before I decided to purchase them, I looked at other sets that were in the $80-200 range. I chuckled when I saw that Bose had speakers in roughly (+$10) the same range (I've learned that Bose has been living of their original 901 reputation for almost 45 years) and that now most of their consumer stuff sounds like s**t). So, I didn't look further. I love the T20s, can mix on them in a pinch, and with their yellow speaker cones, they compliment my KRKs. It was pretty stupid of me to look further than these T20s. Seriously, you won't find a better small speaker system for less than $300!

Sound great in the back of my SUV . The mounting hardware is versatile. Good bass response.!!!!!!!!!!
