Very quiet including ...

Once in the US I had horror of the return flight - again 8h aircraft noise during the return flight were not beautiful prospects. And even though I had earplugs while. So let's see what can be done there. Noise-canceling headphones are quite expensive and seem very selectively to reduce outside noise.

Then I became aware of the Howard Leight SYNC. For $ 20.- can not do so much wrong one; buy and ... terrific!

I did not expect to buy a high-end headphones, the one does not feel. Once connected to the entertainment system on the plane my last doubts were gone. One understands every word, without having to fully turn up the volume.

+ Very good soundproofing (significantly better than earplugs, could not understand the on-board service)
+ Very cheap
+ Cable to the headset can be removed (3.5mm)
+ Sound quality is OK (for $ 20.- there is no high-end)
+ Processing for the price surprisingly good

+ - He is not super comfortable, but there is no torment to wear it (also depends on the head shape from)
+ - For hearing protection looks OK
+ - For ear protection pack size is OK (not foldable, but also not a big chunk)

- Ear pad made of rubber, but it may be necessary in hearing protection as its (quite warm under)

My expectations were exceeded and I now have a full hearing protection. I would have liked to have these headphones rather to travel with.
