I recently tried out the Motorola HS820 Bluetooth headset and luckily I kept the receipt. Upon placing a few test calls I found the audio quality to be quite poor. I was able to hear the conversation well however my voice came in very low on the other end. It did however, fit easily over my ear and was not very heavy. *UPDATE* Since I purchased this headset on eBay I am now suspicious that this headset is counterfeit, mainly because there is no UPC on the box. Therefore this review may not accurately describe this product.
