Isolate outside noise well. Well built.
Best protection against speech, which is so difficult to drown out. I live with a friend who has Alzheimer and his 24/7 moans have me on the edge of insanity. These earmuff have really helped save the day - though they are a bit pinchy tight, I couldnt do without them!!
Great so far
Very Impressed with the quick shipping. Well packaged,ready for use right out of the box. Awesome performance, looking forward to being able to purchase the accessories like new ear pads on the Canadian website sometime.
Great headset, it really does knock out the noise. Then their is the additional 20db circuit, shut the door, goodnight .. Best headset for the money hands down.
Excellent headset for working the outside operations for a major airline. They are comfortable and durable. The noise reduction works well and the speakers work perfect. Itâ€™s exactly what I thought I was paying for.
These are very comfortable, and work well. I was on a project working next to a 7000 cubic inch engine wearing 30db ear muffs that were uncomfortable, and gave me a headache. I ordered these, and had them delivered the next day. These were a huge improvement. I had everyone on the project try them out. Everyone wanted a pair. Money well spent.
Yes, if returned within 30 days of receipt in unused, resalable condition.
No, they do not.
