I bought these headphones to wear during outdoor activities. First, it's incredibly difficult to understand what mode they're in and if they're supposed to record. If you lose your printed instructions, you're out of luck! You won't find any instructions online for this particular model. Trust me I tried for two days. Also, I want to confirm what others have mentioned in their reviews, the video randomly cuts off after 30 seconds and all you're left with is useless audio. You don't get such functional glasses that cheap.
