Sound top comfort deficient

Bought for my mother this headset. Connecting to the TV is relatively simple, the sound is
just great, even at a distance of 30 meters or 2 rooms next to the bathrooms immaculate
Reception. Unfortunately, my mother lamented the next day on strong earache because the device after
Two hours had pressed terribly, I tried over any settings of the voltage
To reduce ironing, unfortunately there were no possibilities to, have your headphones with these settings yourself
taken half an hour and had then still for hours feeling in the ear would push what.
For this reason, we could not keep the device.
If you are not satisfied with something like in this case, is the return of Amazon is a great thing,
pack and ship the same money back.
