Summary: For a cyclists, this speaker is a waste of time. I gave it two stars because it sounds pretty good at low volumes. So if you want high quality sounds from a very compact speaker to play softly in a quiet room, this speaker is fine. But I purchased this specifically to listen to music while cycling, and this speaker doesn't even come close to playing loud enough to hear outside while cycling.
Summary: Did want to like but: paired with a iPhone 4S through a JayBird uSport apt-x adapter, the foxL-v2 emitted a low-pitched humming noise while no music was playing, and a mild background hiss when playing. The sound was less detailed than other non-apt-x bluetooth speakers we use. Returned.
Summary: After having done a ton of research on bluetooth speakers, I decided to go with the soundmatters foxLv2 bluetooth loudspeaker system. Not being quite as expensive as the Bose version, this seemed ideal. I am returning this now and have decided to get fork over the extra bucks for the Bose bluetooth speakers. The soundmatters kept dropping my bluetooth connection.
Summary: I'm sorry folks. I really wanted to like this product but I was disappointed. Sure it does a reasonable job at creating the illusion of full spectrum sound, but in the end something has to give. It won't get loud enough to fill a small room. By the time it comes close the little drivers and cabinet start showing strain and the bass becomes boxy and lacks definition. That is a lot of money for that kind of fidelity.
