The use of the SP700 is made all the easier by the fact that it gives vocal feedback. So when a link has been established with a handset the nice lady hiding inside says ‘connected' and when you receive an incoming call she says ‘call from' and then speaks the digits of the caller's number. However, the SP700 doesn't have a text-to-speech engine like the Parrot Minikit Slim so it can't actually speak the name of the caller, which would have been a more elegant solution.
However, the SP700 does trump Parrot's model with its best feature - the built-in FM transmitter. Not only does this enable you to route calls through your car stereo, but if your phone supports A2DP you can also route music from the phone through the SP700 and on to your car stereo. Both of these functions work extremely well, but it's especially good for taking calls as even though the SP700's built-in speaker is impressively loud - and much louder and clearer than the flat NXT speakers used on rivals like the Parrot Minikit - audio from your car's speakers is always going to be louder and crisper sounding.
To activate the FM tuner all you have to do is hit the button on the right of the speakerphone. The speakerphone then announces the frequency that it is transmitting on so you know which frequency to tune to with your car radio. If that frequency is being used by a radio station you can have the SP700 do an automatic scan for a free frequency and then adjust the setting in steps of 0.1MHz to fine-tune it.
The full-duplex sound quality during calls was very good. Callers sound very crisp and clear through both the internal speaker and when the unit is feeding sound to your car's radio via the FM transmitter. Those people who we called said that although it was obvious we were using a hands-free device, as the echo cancellation would clip the quality of sentences every now and again, the voice quality was still very intelligible because there was practically no background engine noise audible on the call.
Obviously, an internal rechargeable battery powers the SP700. Charging is carried out via a microUSB port on the left-hand side of the device and Jabra includes a car charger in the pack. Battery life was good and similar to what you'd expect from a standard Bluetooth headset. In fact, Jabra quotes a talk-time of 14 hours when using the FM transmitter, but we got around 12, which isn't far off.
We really liked the SP700. It has decent sound quality, good battery life and the built-in FM transmitter is a really clever and useful addition. The only thing it's missing is a text-to-speech feature for dictating the actual names of callers. Other than that, this really is a top-class device.
