Question: comfortable?
Document: They work great and are comfortable. Just a bit of static in the microphones,  but cancel a gun shot perfectly.
Loud, comfortable, and easy to adjust the volume. These headphones are great, are in stereo, and clamp down on gunfire immediately!
very nice. Lightweight comfortable easy to use.haven't got to use them in the field yet, but I feel that they will work admirably.
Works as advertised. Fit is okay, comfortable. Volume control is a little unhandy to use, but hearing is greatly enhanced.
The plastic feels cheap, and the headband is poorly designed for storage--they just don't fold up well.On the plus side, they ARE comfortable...even when broken.
Does everything the description claims. Ear muffs are comfortable and easy to use.I certainly recommend them if you need good hearing protection.
For the price, very comfortable and works well.won't drain your wallet. Would recommend to all my shooting buddies.Not sure on how it drains the batteries. A pleasure to have on your head.
These are the only hearing protection I have purchased, I have worn some other ones but they aren't as comfortable. These fit really well on my head, and the microphone / headphone feature is pretty neat.
Obviously their are going to be better quality sounding headphones available, but for under $25 you can't ask for a lot more. They would be worth the price even if they weren't electronic. Comfortable too!
I believe that is how all electronic ear muffs work but someone correct me if I'm wrong.These ear muffs are comfortable to wear and cannot be beat at this price.
Answer: no
