Ideal for listening to music or making phone calls. However, if you're using a video or taking a photo, there's no way to know if it's on, taking a picture, or turning on a video. You literally have to wear glasses to see the LED light. So it defeats the purpose of taking a video or picture while you watch it. If I haven't missed anything, there's nothing in the manual that could tell me about it. I have other glasses that at least vibrate when I take a video or photo. I was hoping this would do the same thing as I like the bluetooth feature and built in storage. Therefore I can only give 3 stars.
