For the price, this product is a pretty good deal. Connecting to bluetooth is super simple. I was most surprised at the battery life. I use mine for the gym. If you charge it completely (I think 1.5-2 hrs.) it should last 7+ days (if you're using them 2hrs/day) before you need to recharge.
Best headphones I have ever had. Love the blue color. Battery is rechargeable. I used all day and night first day they arrived. Still going strong. Haven't recharged yet. They also have bluetooth.
Very well made and so comfortable.
Work great. Have had for a while now and just as good as day one.
My husband and I bought these for our boys for Christmas and they are working great still (the longest any headphone has held up). Great purchase!
