Query: Poor connection, good sound

I bought this headset as my first Bluetooth headset to work with my Nokia 6820. It was easy to pair, and easy to operate. However, I have experienced continual problems with it staying connected to the phone unless they were within 12 inches of each other and had line of sight.Then, it works fine, the sound is good and the functionality good too. However, the battery life is quite short, lasting only 16 hours on average with very little talk time. Then, it takes 5 hours to recharge it.I've decided to purchase my second Bluetooth headset, in this case, a Cardo Scala 500. Hopefully my luck will be better.
