## Description

Comfortable flexible earpiece is designed for all-day wear. Its in-line push-to-talk feature makes communication easy when your radio is not readily accessible.

Review: Good buy, will purchase again. - I work in TV on set and use it every day. My ear lobes are very sensitive to most ear plugs; even the soft rubber fitted headsets give me headaches and sore ears for days. This style of D-ring headset works well for me, is very comfortable, and allows me to hear people talking in front of me as well as the chatter on the radio clearly. I've had this particular headset for almost 6 months and it's had some rough treatment (and it's been used in some, but not a lot, of rain/snow conditions) but it still works perfectly, so I'm really happy with the durability/price. I prefer the single cord style of headset as well, as opposed to the two cord / piece construction of other standard headsets, which makes feel more similar to an iPhone headset, and less like a big, annoying work headset. It's simple, sleek, and works. I'm 6'3 and the cord is just barely long enough for me to feed it down my back, so I might not recommend it for someone taller, though it does stretch.

Made well. No issues

### ⭐⭐⭐⭐⭐ I can hear you now
*by M***S on April 1, 2024*

At first had issues but it was my radios connection. Switched radio and it works fine. No issues with others hearing me. Clip holds good on a pinched shirt. Took a while to get used to and adjusted to fit my ear but now I forget I’m wearing it.
