Love listening to music while hacking on my computer. The go-rock portable speakers are my prized possessions. I use the go-rock single portable speaker to listen music on mp3 audio player. The battery lasts for few days, always carry this speaker when traveling or spending time outdoors.
Got a second go-rock portable stereo speakers for mostly watching DVDs on my laptop. This speakers are designed in shape of an over sized pill, they break up to form two left and right speakers. The USB and Line-in cables can be retractable easily, just pull the cable and spring action will retract the cable smoothly.
The audio quality of go-rock portable speakers is good. You can unscrew the top for BASS mode. They are small enough to fit into my laptop bag and can be recharged with USB. Never had any problems with these speakers, except once I broke the locking notch by applying to much pressure. If you are looking for great portable speakers, go for go-rock.
