When the law in California forced me to get a blue tooth headset I looked for one that was small and sounded good. This one fit the bill perfectly. It sounds almost as good as my headphone connection on my iPhone. It's clear, and people I call don't complain about the sound going in and out. The only thing some people might not like is how it fits in one's ear. Having dealt with headphones with my phone I didn't have any trouble, and it eliminates having wires, which nearly caused me to get into an accident a few months ago.
