Sensgard shows ultra-simple ZEM headphones
Sensgard, which traditionally specializes in producing hearing protection gear, has introduced its ZEM headphones. They use a simple amplifier for purportedly reproducing purer sound and cancel background noise using a proprietary technique from acoustic researcher Dr. Jozef Zwislocki. The noise cancellation is non-electronic, relying on a physics-based sound filter that reduces noise in low- and high-frequency ranges, with a noise reduction of up to 37dB.
