I am a professional music teacher and I ordered this to take around with me when I teach and need to listen to music with my students. I just opened them and have been listening for a few hours and I am surprised how great they are.
Pros:
-Small, compact. The speakers assemble together into a cylinder and fit into a bag/briefcase.
-Decent sound. They are a little oh the bright side, but the sound is pretty even and clear. It's really impossible to get a deep base with a small speaker, but what they do have is pretty decent. I listen to a lot of podcasts at home, which they are great for since you need the sound a little more bright anyway.
-Easy to hook up. I am using my smart phone and ipad and it's easy to connect.
-Nice range. I tested them out by walking in my apartment and I had to go to the furthest part and around several corners for them to phase in and out.
Cons:
-You have to manually connect the speakers in my phone's bluetooth setting every time. Not really that big of a deal, but a little annoying.
-Not that loud. To be expected with smaller, passive speakers. Still plenty loud for my use, but you can't exactly use them at a party.
Overall they are fantastic and exactly what I wanted/needed.
