SMH210

Performance, Durability, Value, Compatibility.

Performance: Exceptionally high quality transducers provide wide smooth frequency response, reducing the onset of ‘ear fatigue’ for those who must spend many hours wearing headsets.

Deep, comfortable ear cushions have excellent external noise exclusion characteristics, and are washable with ordinary dish washing detergent.

At 7.35 oz. the SMH210 are much lighter than their appearances suggest.

The noise-canceling microphone is mounted on a flexible, steel reinforced boom which can be easily twisted into a comfortable position. The flexible head band is adjustable.

The normal transducer configuration for use with Pro Intercom and compatible headset intercom systems are 400W earspeakers and a 200W dynamic microphone. Electret microphones and lower impedance earspeakers for other applications are also avail able, and combinations of these transducers make up the various models.

For use with Pro Inter com and most head set communications systems the SMH210 are fitted with a 4-pin female XLR-type plug. For other appliations many different plugs are available.

Durability: Because these headsets have only one moving part, and the microphone boom is flexible rather than hinged, a remarkable degree of durability is achieved.

The light-weight cable consists of a copper shield around steel reinforced conductors, and is virtually unbreakable under normal circumstances.

The assembly screws are hidden to prevent tampering. These headsets are easily field repairable.

Value: Low initial cost (compared to other professional communications headsets of equivalent quality), combines with long working life and low cost of repairs to offer outstanding value.
