For the Bluetooth speakers that I want, I need a few things. First they must be as portable as my Vita, meaning it has to be lightweight and small. Second, the batteries must be rechargeable like the vita. Third, the sound quality must be better than the Vita speakers or otherwise there is no point. Forth, the speakers should be stereo so that there is direction in the sound. And fifth, after dropping money on the Vita and its expensive propriety memory cards I would prefer it if I can get the speakers at a cheap price.
After spending a few hours researching countless Bluetooth speaker products, I found that there was distinct lack of portable stereo speakers. It wasn't until I came upon a friend's suggestion that I found the Grandmax Tweakers Go-Rock wireless stereo speakers did I find what I was looking for.
The Go-Rock are a perfect match for me. It is a dual-speaker setup, takes up very little space, and weighs much less than my Vita. It can fit into anywhere my Vita can: my purse, backpack, and even coat pockets. I've found that it's just as portable as my Vita so I have no complaints when it comes to portability.
The battery is also lithium-ion, common in most Bluetooth devices. It retains a charge that can last up to 8 hours, which is perfect for gaming sessions. The batteries last just as long as the Vita itself. It's chargeable via micro-USB so I can also use my phone's charger to charge it as well. My only complaint about the battery is the charge time though. It can take up to 4 hours just to charge the thing.
As for sound quality, it blows the Vita's speakers out of the water. It's still a little disappointing in some areas like sounds in the high and low frequencies, but the sounds in the mid frequencies sound great. This means games with a lot of dialogue and voices are especially fantastic with the Go-Rocks. Furthermore, because the speakers are a dual-setup, I can get the 3D sound I want for the games I play. Overall, the speakers are quite acceptable for what I'm looking for.
What I'm most happy about these speakers though, is the price. Considering the dual-speaker setup, rechargeable battery, sound quality, and portability, it's a steal at the going price of $39.99. Just for 20 bucks I found amazing speakers for my Vita. I've yet to bring the speakers out, but when I do, I plan on using it with my Vita where ever I go.
