The GoodThe Rocketfish Mobile SPX15 is a very compact Bluetooth speaker that has a built-in rechargeable battery, a line input, and speakerphone capabilities. It plays relatively loud for its tiny size.
The BadIt could cost a little less; it can't handle big bass at higher volumes; and it sounds a little thin.
The Bottom LineThe Rocketfish Mobile SPX15 is a decent enough little Bluetooth speaker that's very portable and plays fairly loud, but it doesn't perform quite as well as some of its similarly priced competitors.
Ever since Jawbone jump-started the Bluetooth speaker market with its Jambox, the number of tiny Bluetooth speakers has proliferated. The Rocketfish Mobile SPX15 is one of several new models that have arrived in recent months, and it's decent enough, offering speakerphone capabilities and 10 hours of battery life in a small package weighing a little over 8 ounces. However, the only big strike against it is that it doesn't quite measure up to the competition at its $99 price point. (For the uninitiated: Rocketfish is Best Buy's house accessories brand.)
For starters, it's a bit more low frills in the design department compared with the Logitech Mini Boombox, Monster iClarityHD, and AT&T LoudSpeak'r. It's got a basic, straightforward styling, with a glossy black finish. That's fine, but there's something a little generic-looking about it.
To recharge the battery, you use the provided USB cable, and pairing the speaker was simple enough: you just hold down the power button on the top of the unit to put the speaker into pairing mode. Then you look for SPX15 on your Bluetooth-enabled phone or tablet from within the Bluetooth menu. Once it connects, you're ready to start streaming music or a movie soundtrack to the speaker.
