Review on 🎧 Optimized DefenderShield EMF-Free Earbud Headphones - Universal Air Tube Wired Crystal Clear Stereo Headset with Microphone & Volume Control - Compatible with iPhone, Galaxy, iPad & Other Audio Devices by Kipp Amundson

I've been wearing these headphones for a little over two weeks and have noticed that (1) voice output has stopped working in one ear as tested on multiple devices (cellphone, laptop and hub connectors) and contrasts with fully functional headphones from other brands. (2) Voice input into the microphone is sometimes perceived as muffled by the caller. (3) They fall out easily when you stand up, and (4) Designed to keep the headphones in place when you're on the go, these clip-on earbuds are very easy to remove. (5) Radiation shielding provided by air hoses is unlikely to be required. My wired headphones WITHOUT other brands of air tubes generate very similar electromagnetic radiation near the ear tubes (unlike my wireless Bluetooth headphones. I measured this with an EMI meter. I know this meter works. I'm going to Example able to measure increased EMI radiation emitted near speakers/head (6) Air tube from cables between shoulder and ear level is slightly heavier than cables and more difficult to handle during storage than fully wired connections .expected but given my point 5 in my opinion you I can do without, I will have to return them.
