SensGard Launches ZEM Headphones With Background Noise Cancellation

The SensGard has launched a revolutionary new ZEM headphones that use just a simple amplifier to produce pure sound in the earpieces, unchanged by electronics. They simultaneously cancel background noise using patented technology invented at Syracuse University by renowned acoustic researcher, Dr. Jozef Zwislocki.


The result is pure, unaltered sound that feels as if you’re in the recording studio. The absence of complex electronics also lowers cost and produces a headset weight of just two ounces. The compact unit can be folded to fit easily in a shirt pocket or ZEM case. No batteries are needed.

The combination of ZEM noise canceling feature and non-electric headphone is unique. The flat attenuation of the ZEM is so effective users can turn down the volume and still hear clearly.  In this way, the ZEM Headphones reduces stress other headphones cannot provide.

The noise cancellation feature of the ZEM Headphones is non-electric and so effective that users can turn down the volume and still hear clearly and ZEM headsets eliminate distorting electronic effects, leaving only the true sound created by musicians or speakers.

Normally noise cancellation in headphones is achieved with varying degrees of success using batteries and electronics but the ZEM Headphones uses the same patented noise canceling technology found in Sensgard’s hearing protection devices.

Outside noise is absorbed and eliminated inside the chambers, replaced by your choice of music or communication.  Because background sound is gone, you can listen at a low, safe, comfortable volume.

In addition, eliminating electronics results in reducing the bulk, weight and the need to replace batteries more often.

ZEM headphones are ideal for airplane passengers and anyone who wants to hear studio-quality stereo sound without the distraction of background noises.

The noise cancellation feature of the phones is non-electronic and so effective that users can turn down the volume and still hear clearly.

The physics-based sound filter invented by Dr. Zwislocki reduces noise at both low- and high-frequency ranges, lowering noise levels by up to 37 decibels.

The only electronics in the ZEM headphones are two miniature electro-magnetic receivers that convert electrical signals into sound. They are, in effect, tiny electro-mechanical amplifiers.

The ZEM headphones also features 3.5 mm plug on the electrical cord that is compatible with MP3 players, CD players, cell phones, iPods, laptops, satellite radio and home computers allowing users the added freedom of choice.

The ZEM Headset fits comfortably into the outer ear and stays in place even while exercising or moving about and features headband that connects the two earpieces adjusts easily for fit.

ZEM headphones are available at $90.00 with warranty.
