Review on 🎧 Enhance Safety with Saf-T-Ears Bluetooth Dual Mode Earphones: 25dB Noise Reduction, Stream Music and Calls by Sanai Rosario

I received these headphones and charged them according to the instructions, then tested them for bluetooth functionality and noise canceling functionality and they both worked fine. I used them a few days after about 6 hours, after that the battery died. I've tried charging them again and they don't hold a charge. Notified Revain and they sent me an RMA form to send them back and sent me a new pair. I tried charging them and the red light wouldn't go out. They are supposed to charge in about 2 hours and the light will either turn blue or green (I don't have the instructions in front of me) but I left them on for 24 hours but the red light is still on. I tried them and they really worked. I found that I hear a low pitched tone when Bluetooth is on. I really liked being able to turn on the ambient mic to hear the lawn mower a bit, I could even hear the TV with Bluetooth music on. Unfortunately I'm sending this pair back for a refund. I'll try to find another pair.
