Review: N-ear killer??? - For reference I work on patrol for a major law enforcement agency in a metropolitan area. For the last two years ish. I have been using N-Ear ear pieces. In the two years I went through 6 of them. 4 of them were warrantied and I bought two. So about $300 in two years for ear pieces. Last week my n-ear died on me in the middle of shift. I needed a quick replacement (luckily it broke on my Friday). I have had my eye on a sheepdog ear piece for a while but never pulled the trigger on it because while N-ears were breaking on me left and right, they were incredibly comfortable, and the sound was amazing. But this time I didn’t feel like messing around with n-ears awful customer service, I bought the sheepdog. And I am very glad I did. The overall quality seems good. I’m still unsure about longevity but so far it works amazing. The audio is slightly worse than the n-ear but has less of the annoying white noise when someone keys up. So overall it’s evens out. As for comfort it is on par with the n-ear. It fits amazing. Now for the reason I bought it, cost. At half the price I can say it’s definitely worth the money. Hopefully it doesn’t die on me like the n-ears have.

Well made, works with all my work radios, very comfortable and clear audio.

### ⭐⭐⭐⭐ Works good!!
*by K***L on April 20, 2026*

Audio quality is very good. Wire is very this and almost invisible when wearing. Even though it’s thin it feels good quality. My only complaint is it tickles my ear canal. Kinda hard to get adjusted in your ear right. Over all once it gets adjusted it’s good.
