COMPLETE GARBAGE!! Hole for my 12 inch sub was just about 11 inches. While trying to modify it the box fell apart. What a terrible waste of money. The manufacturer was no help at all, Save your money!!!

I have been using this non-stop since receiving it. It works perfectly for my needs. It came with multiple little rubber inserts so that you can find the right fit for your ear as well as 2 sets of ear clips for more security. I actually love the little carrier pouch, it's cute and functional, not too big, not too small. Pairing was a snap. I charge it up once a day and it gives me about 5-6 hours of listening pleasure. I don't actually use it when talking on the phone; I already have a Bluetooth speaker in my car, so I cannot say how well it works for that purpose. My music comes thru loud and clear so I imagine talking on the phone would be the similar. I don't use the secondary earpiece as I prefer to keep one ear free. I love it and have recommended it to family and friends.
