Sound ID 510 Bluetooth Headset - BlackProduct Review (submitted on January 5, 2013):
Got one for myself and liked it so much I bought another for my boyfriend for Christmas. I love the comfort of this because I have always had trouble with the kind that require a hook over your ear. I am able to wear this for hours with no discomfort and does not get in the way of wearing sunglasses. Still trying to figure out exactly how the app works but great feature. Also love being able to hear media through it!
