I received my Motorola H710 today.  I was able to pair it, charge it and use it without using the instructions, it is that easy to use.  From what I can see, the sound is superb.  It connects immediately when you open the boom.  I had a Motorola H500 previously and had nothing but problems.  I highly recommend this model.  From the reviews I have read it offers superior wind noise reduction also.  Can't wait for summer to open my sunroof and give it a try!!
