I have been using Motorola products for years and this is another gadget that just does not deliver. I had the HS801 headset previous to this one and it worked well as long as it was not in a car (which is what I purchased it for). This disintegrated in about a year. I decided to try a the newest Motorola headset and this one worked worse than the cheaper Motorola unit that fell apart in a year. Connectivity was a big issue. It would drop in and out of connection with the phone. Useless when trying to have a conversation. This is with a Motorola phone! The sound was poor both listening and with others listening to me. They could barely hear me because of any background noise would drown out my voice. This was when the microphone was carefully positioned for optimal sound. The ergonomics are questionable for functional use because one of the sound problems related the the position of the microphone on the "boom" of the headset. While wearing it, the small opening for the microphone would press into my face. Therefore, covering the microphone rendering it useless to having a normal conversation.
