Also, the wired connection for sound is a great feature for when the built-in battery runs down unexpectedly

Another nice feature which isn't unique is that there is an included audio cable so that you can keep listening as "passive" headphones after your battery dies.

It is a really cool feature

The best feature was the noise canceling.

They sound terrific, the noise cancelling works very well, the easy interruption feature is brilliant, and the battery life is great

Which is why the feature that can briefly let sound through is great

These are good headphones with one really great feature

The Panasonics have a great feature that I really like.

They're comfortable, sound great, have excellent features, and perform well

The coolest feature on these headphones is the “Ambient Noise Enhancer”

The really innovative feature is that they can also enhance the sound around you

This feature is fantastic

Add three levels of noise cancelling, cool features like touch sensitive for quiet/listening

Other reviewers have said it, and it bears repeating: the noise canceling feature on these headphones is exceptional, and I believe the best there is currently.

I love the Ambient Sound Enhancer Sensor Panel feature because say I'm listening to

These Panasonic Premium Hi-Res headphones have a unique feature that I adore and that other frequent travelers should appreciate.

They feel light in my hand as well as on my head.

n’t work very well
