Review: Not Worth the Price - I use these headphones in the shop while running woodworking machines. Pros: They used to block out a decent amount of noise. Cons: Noise cancelling is worse than using it just normal. I have never noticed it block out any frequencies. It gets a lot of feedback loops that cause bass shuddering and are very annoying. Audio quality. I have had better audio quality in any set of $15 headphones I have had. Durability. I have never had any accidents with these and the foam pads are starting to come apart with normal use. Bottom line: Not worth it at all for the price. For $20-$30 these would be worth it. Review: noise canceling earmuffs - Too tight on head plus where battery is there is a rattle that is annoying....Replacing battery can be quite the chore as the piece has to be screwed off and getting it back in the correct place is annoying because the sides are rubber and you have a hard time getting it in place. Occasionally I have a loud shrieking sound in my ear which is quite painful....over time that seems to have calmed down a bit, just hope it doesn't return! Prefer my Bose noise canceling headphones but, unfortunately, there is no NRR on them and after I was allowed to wear those for 6 months at work, they changed their policy. Now everything has to have a NRR and again these were the only ones I could find in an affordable price range....Wish I could wear my much more comfortable Bose! I could actually hear with those and with these I still have a hard time hearing voices. ## Features - combined passive and active noise reduction - electronic reduction of low-frequency rumbling noise - audio input for use with portable audio devices - over-the-head model PA4000 ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Pro Tech Technologies, Inc. | | Part Number | PA4000 | | Item Weight | 0.317 ounces | | Product Dimensions | 6.93 x 1.57 x 4.17 inches | | Item model number | PA4000 | | Is Discontinued By Manufacturer | No | | Size | full size | | Color | Black | | Style | Modern | | Item Package Quantity | 1 | | Usage | Stereo | | Batteries Included? | No | | Batteries Required? | Yes | ## Images ![Noise Canceling Safety Earmuff PA4000 Over-the-Head Model - Image 1](https://m.media-amazon.com/images/I/41vWPbXMtfL.jpg) ## Questions & Answers **Q: How good are these for working around jet noise on an airport?** A: I have used these in a machine shop screaming through materials at 140dB. The noise level was very comfortable with these on. I could listen to instrumental jazz and still get things done. Perhaps you can relate that to jets. **Q: Can you determine the direction of the "uncanceled" audio coming in from the microphones? (I'm NOT asking about the aux input.)** A: I can tell the direction of the source from which non-canceled noises are emanating when I am wearing the headset. I wear them on a Ford 8000 which has the muffler exhaust right up in front of you. Very Loud, without the headset on, but very nice with the headset. After about 4 hours of constant use, the headset does tend to feel like it is tight on your head. I am glad I purchased them. I used to just use the foam ear plugs, but that was not enough noise dampening. I hope this answered your question. **Q: Would this muff work with impulsive noise?** A: What is impulsive noise? This is by far the best noise cancelling device around. I use it exclusively with all my power tools especially with my back back blower which is very very liud **Q: built for hardhat** A: No, it will not work with hardhats ## Customer Reviews ### ⭐⭐ Not Worth the Price *by A***R on June 29, 2017* I use these headphones in the shop while running woodworking machines.

Was aiming for a price range around $100 to $150. Decided on this pair. Whoops! So the Pros - it does what it says it does. Definitely reduces noise. Given I work in an industrial area with ridiculously loud machinery that makes constant loud noises all day, non-stop, I can attest to needing this kind of technology. However, a set of decent, basic in-ear plugs with a cheaper, $20 headphone set would probably be more than sufficient in combination. The active part is lame, based on the above statement. And, as mentioned in another review, there can be weird shrieking noises at first, particular when using the headphone jack to listen to music or what-have-you. Given the sheer volume of noise I'm already dealing with, I'm not always using that feature. In fact, if you use ear plugs inside this piece, the "active" noise cancellation seems pointless and does not add an extra reduction. Now here's the ultimate issue: NOT COMFORTABLE. This was what I was going for when doing a lot of research given I wear a set for a full 6 hours on any given day. These are way too tight. And I have a rather average side head on a 5'8, 145 pound body. I've been slowly trying to stretch the top part a bit. I'm guessing it was built this way to ensure the "cups" stay tight on the ears to reduce noise. Also, the product arrived in plastic bubble bags. No box. Was this a returned item resent out? Not sure. But given it was labeled new, this made me a bit perplexed. No scratches or anything otherwise that made me think used, though. In Summary, The reviews and research led me to believe this was the perfect set for a long work day. I was wrong. Don't make the same mistake. In theory, this would have been a good set. Next set I purchase, based on research, will probably be a David Clark set. Feel welcome to leave feedback or comments! UPDATE ONE YEAR LATER: Comfort has improved incredibly after stretching and a combination of both it, and myself, getting accustomed to our shapes. The static or shrieking noise is gone. Not sure why. Cord related, device related, headset related, who knows. But it's gone. I added one star because of these two things improving over time. Though definitely was not the case upon first purchase. The other thing to note is this headset can take a beating. Industrial daily use and it still functions both as a noise canceling device and audio device to play music or take phone calls. It's not the best at phone calls, but it does function. Adding another star to bring it up to four because of durability. All in all, would I buy again? Probably not. I think I would go with a david clark headset if I'm going to spend this kind of money again. Or just go cheap as my comments above mention with a combined audio ear noise isolating device. It's worth it if you're NOT trying to get the features of a david clark with mouth piece audio function AND also don't want to use ear pieces inside the headset itself. Note that it mostly eliminates lower frequency noises. I'd call them "heavy noises" ie: metal hitting metal (from experience). It allows people to talk to each other (you have to talk loudly, but you can talk). This is another reason I brought to four stars. Why four stars but wouldn't buy again? Because it won't suit my purposes in business/industry. It might suit YOUR purposes at the home without need of communicating with your business partners/etc. I'm impressed at the beating this thing can take though (and needed to repeat that). Hope the update helps. UPDATE THREE YEARS LATER: Still works! Definitely has some wear and tear from daily use and being beaten up quite a bit, tossed about, etc. Wear and tear caused the opening that holds the battery to get more finicky about closing properly. But can't complain as it was probably my doing from it getting smacked around quite a bit. Some of the foam that goes around the ear is starting to disintegrate a bit. However, having it's home in an industrial warehouse with it receiving quite a bit of roughness mixed in with the fact it's home is not heated/cooled very well, not sure I can blame the product itself for that. Also, that's more of a heavy-use wear item. I'm much more impressed in the electronics component that has held up, which is what makes this a different product than a standard headset. My recommendation above still stands as far as meeting my expectations and what would be a cheaper solution. However, if other products to compare and price weren't a factor, and I was to just discuss this individual product, three years later, it still works. That's a terrific sign. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/6904532-noise-canceling-safety-earmuff-pa4000-over-the-head-model](https://www.desertcart.vu/products/6904532-noise-canceling-safety-earmuff-pa4000-over-the-head-model) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
