. The SuperTooth is great, and no doubt it has more resources than the other ones. But sometimes you need more privacy and a headset will give you this. The SuperTooth gives the option of connecting a corded headset, and I see this as useful if using the device at home or in the office, so you don't need to hold your mobile phone while having a conversation. But the MultiTooth is very functional and can be used as a headset when away from the car.
