Right Tim. There's no app. It's like spinning your finger to turn up the old 
IPod Nanno. On the subject of touch though things like the touch strip on the 
Toshiba lap top could get confusing. I had 1 and yes I kinda learned some of 
the things where on this touch strip where they were. But there was always the 
chance you could hit something else.

since sighted people can't see their ears, how do you think they use the touch 

They use touch.

They are totally usable by sighted and blind people.

Why would a blind person be less able to move their finger up or down or left 
or right than a sighted person?

They also sound exceptional in my view.

As I mentioned in an earlier post, though, the tuning app is not accessible, 
but I have found no need for its use.

I've just read a review on these and they would be an unmitigated disaster for 
anyone who is blind to use.

Firstly the review clearly states that the touch panels - these cans have two - 
need to be controlled with precise movement and mistakes are easily made so - 
if someone with sight is having trouble - just imagine what it would be like 
for someone who is totally blind?

The command activated by the gesture is voiced and the reviewer made mention of 
how frustrating he found it when he say gestured for the volume to be made 
louder only to discover that he'd skipped to the next track in his music 
collection, not too pleasant I would think.

The user also has to make gestures when answering incoming phone calls from the 
mobile, need i say any more.

Far superior? Well both these headphones and the MM550X have AptX for 
Bluetooth, I've had the MM550X and - whilst they have a few design faults and 
the noise cancelling isn't as good as it perhaps could be - I've not been 

Noice scance3lling is something I've never bothered about anyway myself.
