Question: I need a minimum Osha rated protection of 85 db/mW, and was wondering what these are rated at?
Document: Both of the "noises" got reduced, but only in a barely discernible amount. you have to keep switching Pyle on and off to tell the difference. Headphone fitting has been checked/adjusted many times but resulted in no significant improvement.I then tried my old audio-technica ath-anc3, which is rated only 85% in noise reduction. (it's in-ear instead of over-the-ear as Pyle). The difference before and after you turn on the switch is significant.
I am very impressed with the headphones. They work very well. Unless you are a real audiophile, there is no need to spend the extra money on anything else.
Excellent product, does everything I need.Will recommend it to others. Does everything advertised.I enjoy exercising and listening to music.
I have no personal contact, nor do I have connections with Pyle. Not bad Headphones, and a great, no outstanding price with high quality headphones, what else do you need to know. God Bless.
I was completely disappointed in this product. I was looking for a reasonable pair of noise reduction headphones for traveling; with these you will need a seperate suitcase to pack them in. They are HUGE and very bulky. They are probably just fine for in home use but definitely not what I was looking for travel.
I just purchased this PHPNC45 Headset from Amazon. They seem to work real well so far.The manual should have been more detailed and should have a diagram to show how the battery cover comes off.Another complaint is the $20 fee to return from warranty service. If I do need to send back for warranty service it will cost 3/4 of the price that I paid for the headphones with the cost of shipping them out. Just not fair.
These don't do that. As a matter of fact...I couldn't tell a noticeable change. Now if I turn on music and crank these puppies up...then the aforementioned sounds vanished. But so did the bird, cause the tunes coming from the earpiece scared him off. My wife told me that I couldn't take these on the plane cause the other passengers would need Noise Cancelling headphones to drown out my Pyle Home PHPNC45 High-Fidelity Noise-Canceling Headphones.
I work in a very nosiy work area and need the noise cancelling. When I read the insert when I got it, I discover it was really designed for subway or plane use. It did not preform as I expected. It could not even block 50% of the noise. The earphones are huge and were hard to fit my head. One pro it allows you to adjust the volume for your MP3 player. Not one of my better choices.
This is certainly a manufacturing error to require the cord to need connecting as oppose to be permanently part of headset itself prohibiting movement of the connector internally.
These headphones were highly rated in other reviews. They are nicely made and the case is a quality item, however, the noise canceling is not that good, and I doubt very much if it is 95%. I was really surprised at the amount of noise that was still evident when using them. I tried other batteries, but it didn't help. I waited weeks for this shipment, expecting a high quality product, and I was very disappointed.
Answer: 85 db compares to busy street noise, or a vacuum cleaner.  These headphones in NO WAY come close to being able to block that level of noise with it's so called noise cancellation effect.  It can only mask outside noise of that intensity by making it's own noise, that is, by serving in a headphone capacity and playing music or other such input.  Noise "cancellation" is a grossly misleading appelation when applied to these headphones.  They DON'T block noise to any appreciable extent--not like ear plugs or shooter's headphones do/would... which is what I suggest you need if you're looking to protect your ears, not blow more noise into them.
