when I'm watching anything late night and have to be mindful of the neighbors
Hi I bought these seinhassuar(spelling) noise cancelling headphones because my Infocus projector sounds like a screaming banshee. They killed the external noise, and the sound is as good as your out put device.
I had them plugged into a Pioneer, with amazing surround like sound. Then, I bought a Cambridge Audio receiver, and the sound was even better. I know, they say it only outputs stereo in headphone mode, but I tell ya it sounds like surround to me!
