These new noise-canceling headphones from Sensgard don’t need any power to operate, which is amazing, since most noise-canceling headphones and earphones do need some kind of electricity to make their filters work.

The Sensgard ZEM headphones come with a simple amplifier. The noise-canceling technology comes courtesy of Dr. Josef Zwislocki and cancels background noise without requiring any electricity. It’s based on a physics-based sound filter, which reduces noise in the low and high frequency ranges by 37 dB.

While they don’t look all that stylish, I have to say that I’m intrigued by this technology, but I’m not yet ready to get rid of my Shure earphones. Nevertheless, they will be available soon and cost $90 (USD) for a pair.
