    • Good buy, will purchase again.
Color: Black Size: Single
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. ... show more

    • Works very well!
Color: Black Size: Single
Great quality, easy use, and very helpful to have rather than a walkie at work. I can hear so much better now and respond more efficiently

    • Good headset
Color: HKLN4599B Size: 9"L x 7"W x 4"H
Great headset. Stays on my ear all day with no issues. I had to bend the earpiece a little bc it was too tight as first but after a few wears it's perfect. Works with the c1110 radios we have at work. Just make sure you push the plug in ALL the way to the radio. I can be heard clearly with no issues sending or receiving. ... show more

    • Sounds Great, But A Bit Uncomfortable Around The Ear
Color: HKLN4599B Size: 9"L x 7"W x 4"H
The sound quality for this is incredible and it's also nice that I don't have to stick it in my ear. I wish the cable had an extra 6-12 inches in length however. I do feel it pulling at times. Throughout the day, I do find myself adjusting it because it isn't the most comfortable device around my ear. Despite that, it works pretty well and maybe I just have big ears. ... show more

    • I can hear you now
Color: Black Size: Single
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.

    • Great headphone for work
Color: Black Size: Single
I bought this to wear at work (Aldi) because we move a ton and I was having trouble hearing my walkie. This stays attached to my shirt great and even though it doesn’t have the part that goes into your ear canal, it still stays over the ear without issue. Has great sound quality and is very comfortable, no ear in from it sitting on your ear. ... show more
