Review on V5.0 Bluetooth Headset for Cell Phones - 16 Hrs Talking, Noise Cancelling Mic, IPX5 Waterproof - iPhone, Android, Samsung Compatible by Bobby Montoya

I've had this bluetooth for a little over a month. I use this every day. I gave it a 3 because initially it worked great, the sound was good, everyone could hear me, I could hear them, I could listen to music easily and without noise. Started freaking out last week. The button goes on and off for a long time, the reception disappears, the callers sound muffled and I can hardly understand them. It's not expensive Bluetooth, but I was hoping it would last longer than 2 months. As I don't have any other bluetooth I'll keep using this one and see if this problem persists.
