Question: Has anyone used these with behind the ear hearing aids, and how does this set differ from the $79  Audio-Technica ones?
Document: I did a lot of research on buying a set of noise-cancelling headphones and finally settled on the Audio-Technica ones. My dad just bought a set of Bose QC15 headphones and we had a chance to test them last night blind with a few other guests. The results were surprising. No one liked the Bose. (Even though when I tried the Bose I thought that they were quite nice and very effective at noise cancellation despite the uncomfortable amount of ear pressure they cause.
Normal conversation, Peanut m&m;'s, these are noises that I hoped would fall into the category that would be blotted out. But these don't work that way. The hearing protection I used for shooting was more of the affect that I was looking for. But somehow I can't bring myself to wear Remington ear muffs at work. At least a set of headphones could be reasonably explained away. But suffice to say, these noise cancelling headphones do NOT work like hearing protection.
I have &#34;In the canal&#34; hearing aids and have ben traveling a lot. I needed headphones and there were no recommendations for use with hearing aids. Over the ear and noise canceling work. The only complaint is on some airplanes I can't get the volume low enough, a new problem for some one who can't hear so well. All in all a ver satisfactory product.
Based on Amazon reviews of multiple noise-cancelling headphones, I chose Audio-Technica based on 90% noise cancel experience and less than half the price of Bose, and better construction than Bose. I just used them for multiple flights and am very happy with them...especially on my flight back which had very noisy passengers in the rows behind me.
I received my new headsets today. This is the most I've spent on headsets for gaming. I have a specific hearing problem (stone deaf in left ear, good hearing in the right) that can't be corrected by hearing aids and includes fairly constant tinnitus - mostly hissing (seashell sound) that I've discovered can be made almost completely ignored with noise cancelling headsets. I discovered this advantage while using a friends BOSE QuietComfort 15s - but didn't have $300 to spend.
If you are reading this you are probably looking for a good alternative to the Bose headphones. I bought these because of the great price point and the pretty good views. I have used bose over the ear headphones and these technica headphones do just as good of a job. They are about as comfortable as the bose and sound good. Don't have the extreame bass the bose ones have. They also come with a carry case and the hookup for the airplane.
I had a 14 hours flight that I wasn't looking forward to. I hate wearing those in the ear earbuds that hurt after a couple of hours. I also don't like blasting them to the max so I can hear on the airplane, i KNOW that's not good for my hearing. I can't afford to buy the Bose headphones so I checked Amazon to see what my other options were. I read the reviews and found the Audio-Technica headphones. I love them! The noise cancelling was great!
I highly recommend purchasing a pair of Audio Technica ATH-ANC7B Noise Cancelling Headphones!!!!!! !Before purchasing these Audio Technica ATH-ANC7B Noise Cancelling Headphones I compared numerous brands & models. Cheaper ones were less quality, poor audio/noise cancelling and uncomfortable. Higher quality ones were over priced and compared to the ATH-ANC7B's the additional cost was unjustifiable.I just used these on flights from Newark to Roatan and loved everything about them.
Who decided to make the head-strap to NOT be very long? Who decided not to use the softer padding over the ears? And why aren't the ear-cups a little bigger to surround my ears better.I'm ready to try on-ear model and see how that does. Consumer Reports rated even the Audio-Technica on-ear model better than these. What a disappointment, don't waste your money.I'll be putting mine up for sale on e-bay if anyone wants them.
Noise Cancelling:  Worked really good to cancel the air plan noise. I used on international fly (12 hours fly) Watched movies, listened to music and audio book from both my ipad and on-board entertainment system with the adopt come with this head phone.Sound: pretty good (you cannot compare to 300USD ones, but really good already).Comfort: Yes, it does hurt my ear after wearing it for long time, the headset press too hard. But I can still tolerate it.
Answer: Wish I had more experience so I could help you better. They are a pretty snug fit for me. If your heading aids stick out beyond the back of your ear I wouldn't think they would be a good option for you. On the other hand if they don't extend beyond your ears I would imagine they would work just fine. As for your 2nd question I'm guessing the $79 dollar set doesn't have the noise canceling feature which works great!!!
