The earbuds will not stay on! I tried all the sizes and my friend try it too and they fall off immediately. Sounds quality pretty bad as well. Returning.

Arrived on time and I can see a difference in my 10 year old sleep. She falls asleep immediately no more fuss.

The response to my warranty claim was quick, easy and hassle free. I appreciate that. This is my second pair of headphones and they have been great. My only issue is they get tangled up all the time. Not as convenient as the retractable head set I used to use. My doctor saw me wearing them and said get rid of those right now. You are radiating your brain and recommended I buy Defender Shield headphones. It was a good thing to do. I had an experience 2 years ago with a Smartwatch I had worn for several months. I noticed pain in my arm and when I stopped wearing it the pain went away. I don't use Bluetooth anymore. People need to be more aware of the dangers of EMF. Thank you.

The pouch part itself is five stars but the strap and cheap plastic hardware leave me insecure about its strength if I’m out and about. I can’t just throw it on and forget about it. Also, The flimsy strap makes it so that it moves around my body to the back of my body unlike other similar type cross body pouches with more substantial straps that stay to the front of the body.

Thank you for your efforts to recognize EMF/ RF Radiation and offer Education and PROTECTIVE Shielding products that help folks like us attempt to survive our assault into serious Electromagnetic Hypersensitivity. Everything we thought was good and true about living in the US changed once we were forced to get informed. Please don't wait, be proactive with EMF Radiation and Infrasound Vibration as the symptoms can be excruciatingly painful and disabling; stealing your hope for the future. Our best resources; Geovital academy, Austria - *Dr Mariana Pereira's 30 year research video; Infrasound Low Frequency Noise - Dr Barrie Trowers; wifi dangers videos - Dr Sharon Goldberg; EMF Effects & Immunology Videos. Please start conversations and advocacy to have Tested Proven EMF Rad & ILFN/Vib SAFE modest Homes (libraries & churches) for Everyone. ~ Let's find ways to get thermal curtains and high R insulation in every home/apt to lessen the need for toxic man-made energies. ~ And use our own brains, rather than RF microwave weapons, to create safety strategies that help protect all humans sanely & humanely. Thank you Defender Shield; I wouldn't be able to be online limited hours weekly without your e.gloves. Sewing the tips with thread early on seriously helps prevent edges from opening. Sincerely, J
