Summary: Poor volume level! Looked at several wireless speaker options and the volume on this device was tiny, comparatively speaking. I settled on the HMDX JAM. I tried four other brands and this had the worst sound output of all 5 devices tested. The bass was okay at best. Look elsewhere!
Summary: First off, it's small. Really small. Like, "it can fit in my coat pocket" kind of small. Second, for its size, it throws some sound. But, if you plan on going out doors, forget about hearing this thing. Indoor environments this thing really thrives, but when you go outside, forget it. Also, I had an issue with some of the construction quality which I think was very isolated.
Summary: The sound quality was great for about a day, and then it gets fuzzy and pops like the speaker is blown without ever listening to it at high volumes. The small drivers just don't handle sound well, and now I have no choice but to listen very quietly or my music sounds very scratchy and poor.
Summary: Nice size, long battery charge, and reasonable sound for a small work office space. I could never get it to work with my Dell Laptop (nor could my IT department). It paired easily with my iPhone but cuts out frequently and has an annoying buzzing every once in awhile which often results in it disconnecting from my device. It has gotten worse over time and I wish I'd kept the original packing as I would definitely have sent it back.
Summary: I recently bought the ipod dock version of this logitech unit and this one. After playing them side by side the dock is clearly superior. the bluetooth connection, though only a few feet from the source, sounded blocky and staticky. The dock was clear and clean on the same song and at the same volume. I made sure not to push the wireless unit to full volume as some other reviews noted, but even at mid volume the sound was not even passable. I'll be returning this unit.
Summary: Pros: Amazing Sound when plugged in, Nice Looking Cons: Faulty Battery. Switches off intermittently when on Battery, WEAK REMOTE FUNCTIONALITY Update: As mentioned by people who posted their reply for my review, having the volume at less than 80% seems to solve the issue of the speakers switching off. This again is not 100% guaranteed but the switching off frequency is lesser.
