I use the Sony WH1000XM3 headphones in conjunction with Phonak computerized hearing aids, before this I have been using various 'on the ear' type headphones. With 'on the ear' of headphone the hearing aids are of little use because the microphones are outside of the ear cups. No matter, I have been using the graphic equalizers on the tablet computer or PC to help compensate for not being able to make use of the aids. Unfortunately with other noise cancelling headphones that I have tried, the 'on board' graphic equalizers on the PC and computer tablet for some reason do not function. However, the WH-1000XM3 headphones have their own graphic equalizer and much more built into their app, which I can make use of with or without the hearing aids. Certain other noise cancelling headphones that I have tried do not have this capability and to my ears they sound pretty dull, in comparison with the Sony. Also the 'over the ear' function of the WH-1000XM3 ear cups encapsulate the ear and the hearing aids. It is a shame that certain other noise cancelling headphone manufacturers do not recognize that just as people have different visual problems. That is, a variance between each eye, long or short sighted, astigmatism etc. the same goes for our hearing. There is no doubt that the Sony WH-1000XM3 headphones are well ahead of the competition in this matter, they also have an excellent build quality. Well done Sony.
