Review on 📱 Cell Phone Bluetooth Headset, Wireless V5.0 Bluetooth Earpiece for iPhone, Android, Samsung, IPX5 Waterproof, 16 Hours Talking Hands-Free Earphone with Noise Cancelling Mic for Outdoor/Business by Eric Pruett

I've had 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 more than 2 months. As I don't have any other bluetooth I'll keep using this one and see if this problem persists.
