I recently purchased this product from Amazon. Amazon was great, the product, however, was not. Even at the discounted price of Amazon the S9 is still quite expensive. The S9 has great features I really liked. The sound was good on my end but people on the other end said I sounded like I was under water and in a tunnel. My biggest problem though is that after only 3 weeks the phone and volume control portion of the headset stopped working. Volume control would randomly adjust and the phone button would randomly make phone calls. I would be talking to someone and the voice dial would go off. This would have been a minor issue if it only happened once but for 2 days I couldnt use the headset. I returned the S9 for another. Once again Amazon was great but sure enough afrer only 3 weeks it did the same thing. Sorry Motorola but this is a bust for me.
