Question: Anyone using these in "cubicle city" where many of us work these days?   Do they effectively block out office chatter?
Document: I work in an open-plan office and conversations at the other end of the room, loud meetings in nearby rooms, etc. really break my concentration. These hearing protectors really help me to block out the distractions.
I was encouraged to purchase this product after reading Mark Carroll's review here on Amazon.com because my circumstances are nearly identical to his. Let me repeat what he said for it deserves repeating: "I work in an open-plan office and conversations at the other end of the room, loud meetings in nearby rooms, etc. really break my concentration. These hearing protectors really help me to block out the distractions." The improvement of these over the Silenceo ear muffs I had purchased through Wal-Mart is overwhelming - and at little cost for such quality.
I've owned mine for probably 5 years. About 1985 I bought a pair of Thunder 29's, then another pair a few years later, so two could work. These are slightly more comfortable than the Thunder 29's. I bought these because the plastic cushion on my first Thunder 29's cracked (after about 20 years use) and I wanted to try a different mfg.I have many uses - I use them when I need to focus and control what I'm hearing. I'll often stick a pair of MP3 earbuds in and listen to my own music while mowing or trying to ignore other sounds.Lately I've been using them with some Milwaukee earplugs (NRR 27 dB)Milwaukee 49-17-3200 NRR 27 DB Corded Reusable Earplugs, Box of 50when I'm milling trees with my Stihl MS 660 w/ DP muffler, which puts out about 120 dB or more.
Bought this item after reading the great reviews. I wanted something to block off the noisy office but didn't want noise canceling head phones as I didn't want to listening music, just wanted to cut down the volume in the office. This worked perfectly.
Needed these to protect hearing when using lawnmower. They work quite nicely. Husband can't hear a thing - which is the goal. No damage to his already damaged hearing. Yay! "You'll like them", he says.
The good is the ear muffs really block the noise and they firmly clamp onto your head.The bad is the adjustment of the head size is not easy and takes a minute or so. I would NOT recommend these headphones if more than one person has to use them back and forth. If only one person is going to be using them, then they are great. They clamp the head more than the 3m ones. The 3M ones look exactly like the Peltor ones. If you get theses ear muffs on, they are not coming off unless you intentionally take them off.
Very good product. I share an office with three other grad students, and basically need total silence for the kind of technical research work I'm doing. These headphones don't completely kill the sound in the office, but they eliminate about 80 percent of it. When you also wear in-ear earplugs, you wouldn't hear a bomb going off with these things on. They're pretty comfortable to wear for long periods, although they can be hot sometimes. Also, they're a great way to signal to others that you're busy and don't want to be interrupted -- a useful social wall between office mates that has really reduced distractions and improved my productivity.
Bilsom Thunder T3 Dielectric EarmuffI used these when crossing on a freight ship from Europe to New York City, as my cabin was located next to the very loud engine room. I slept with them on. They don't block out all the noise, as I could still hear things even when I had both foam Earplugs (HOWARD LEIGHT NRR 32) and the T3 Earmuff (NRR 30) on. Cheap plastic material and rather bulky so they are hard to sleep with unless you are propped up with a pillow. Fit is rather tight so it hurts after a long while.Also noted: I felt doubly nauseous as I became sea sick and dizzy from hearing sensory depravation.
very nice passive noise reduction. Does great job of protecting my hearing while using power tools.
These earmuffs are the best I have ever used. I have only used them for a little while so far but they are not too tight as many other reviews say. The are large but that gives me plenty of room to have ear buds under them and they cut out so much outside noise that the volume does not have to be very high to hear the music over the sound of my mower, which is very loud. Highly recommend.
