Sensgrad, expert in hearing protection, launches the ZEM noise canceling headphones. Unlike most noise-canceling headphones on the market, the ZEM uses a non-electronic way to eliminate background noise. Outside noise is absorbed and eliminated inside the chambers, replaced by your choice of music or communication.
The ZEM comes with an adjustable headband and can be folded for easy carrying. Two models are available, the 26db SGZP001-26-BK ($29.99) and the 31db SGZP001-31-BK ($39.99). They both feature miniature electro-magnetic receivers producing broadband output with zero bias.
