Review on 🎧 Invisible Wireless Covert Earphone Kit with 3.5mm Plug Inductive Loop - Enhance Music Listening Experience (No Microphone) by Mario Schultz

The device works, but even with the volume on my mobile phone or radio almost to the end, the signal volume in the handset is very low. If I move the neck loop just below my ear, the volume is acceptable, but wearing the neck loop this way isn't practical. The idea is to hide the loop under the coat's shirt, which means it's at least 4 or 5 inches from the ear, which is too far for this device to be very effective. Either a slightly larger telecoil in the handset or better amplification circuitry is required. The earpiece is so tiny that you have to be very careful not to put it too deep in your ear canal. This headphone could have been better if it was a bit bigger with a bigger telecoil inside. Professional devices are much larger and cover the ear canal, so the sound comes through much better. You get what you pay for. It was cheap so I decided to give it a try but I don't think I can use it in a professional setting. If I were in a crowd with lots of talking going on around me, I could never hear this thing over the usual crowd noise.
