Review on Enhanced Security with ARC Surveillance Listen Only Earpiece - 3.5mm Plug for Efficient Monitoring by Travis Smith

Great earphones. I chose these earbuds based on the good reviews and needed them to be reliable as I work in law enforcement and use them every day with my duty radio. It has a wide volume range and voices are very clear. The supplied acoustic tube did not last long and had to be replaced after a few months, however manufacturers recommend replacing the acoustic tube approximately every 6 months. Overall I'm very happy with it. I would buy it again and recommend it.
