The Motorola HT820 Bluetooth Stereo Headset works exactly as it is promoted. It has ease of use and is very durable. I use it mostly while working out for 90 minutes 4-6 days a week and after 3 months of hard use has held up very well.Pros: Ease of operation. A single charge can last up to 12 hours. Music clarity is very good. Using the headset with a cell phone along with music is excellent. Microphone picks up your voice and silences the backround noises very well.Cons: The volume is not as loud as I would normally like it when using it with an MP3 player.That is why I did notgive it a 5/5 rating.I would recommend this headset to anyone.
