Wireless is all well and good, but nothing beats a good-old corded connection when it comes to sound quality. The Soundmatters FoxL Personal Audiophile Loudspeaker speaker is capable of an impressive audio response given its size (and as well it should with "Audiophile" actually in the product name). This is no doubt thanks to the two 1-inch-in-diameter Linear Magnetic Drive "Twoofers" (tuned to 100Hz) on the front, combined with the FlatMagic bass radiator on the rear. The FoxL offers exceptional clarity, with plenty of detail on the high end, and mids are smooth and warm without being overly forward. Bass, while not super thumping, is tight and present...and you will feel it if you're touching the surface the speaker is sitting on. We'd recommend hooking up an external subwoofer if you really want boom, though. Stereo separation is not on par with what you will get from two separate speakers, but this little unit sounds surprisingly open, and you needn't necessarily sit directly in front of it to enjoy the music. (It also gets rather shockingly loud.)
We paired the Soundmatters FoxL mb Personal Audiophile Loudspeaker with a Blackberry Storm in order to test the Bluetooth capabilities. Pairing was a mostly simple and quick process, though you may want to note that the Bluetooth button on the speaker feels unresponsive. It actually works fine--just make sure to follow the instructions in the manual. Unfortunately, sound quality deteriorates noticeably over the wireless connection: high-hat cymbals and other high frequency sounds came through with some static, and music suffered from a bit of distortion on the whole. Because of this, while we highly recommend the Soundmatters FoxL Personal Audiophile Loudspeaker, we don't suggest you spend $50 more for the Bluetooth connectivity unless you really loathe wires.
