I haven't even expected Motorola product is going to be this much worse. I really had a bad experience with this product.1. Voice is just okie.. I felt like a hearing a stereo 10 years back recorded voice.2. I can able to hear only in left ear when I am attending phone call, I don't know this is simply silly. I am having another Jabra BT620, this item is superb but only problem is it is little bulkier..3. The product is not at all comfortable for wearing.4. I attended phone call with 10 minutes duration I got pain at my ears. With Jabra 620 I use to attend offshore conference calls in the night around 30 to 60 minutes I never had such kind of bad experience.Finally I returned item, haven't left with any other choice.
