On the other end of the line we found that the built-in speaker was impressively loud with enough volume to be comfortably heard above engine noise and road noise. That said, when the speaker is working at it's loudest volume setting it does become a little screechy as a bit of distortion and clipping creeps in. Nevertheless, on all but this highest setting voices via the speaker sound nicely distinct so on the whole it is easy to understand what callers are saying.
In the box Jabra supplies a USB car adaptor and lead for charging the speakerphone via its microUSB port. Unfortunately there's no wall charger included, so if you want to be able to charge it outside of your car you'll have to hook it up to one of the USB ports on your PC or laptop. This is not exactly an unlikely scenario as the device works great as an office based speaker phone for you mobile when you're out of your motor. During charging a small LED on the top turns red and once it's fully charge this switches to green to let you know it's ready for use. Once it's fully charged Jabra says that the battery is good for 10 hours of talk time or around 23 days on standby. In our tests it didn't perform far off of those figures. We got around eight and a half to nine hours of use out of it before it needed to be topped up with juice.
It may look a little bit plasticy, but the SP200 is easy to use thanks to its large volume dial and simple control set up. Add clean and crisp call quality into the equation and you've got an impressive budget speakerphone option. Its older brother, the SP700 is still the more impressive device, but if you can't quite stretch to its higher asking price then the SP200 is still a good second choice.
