Cardioid Dynamic, Headworn with Dual Earphones
The SM2 is a comfortable, self-adjusting headset with dual-enclosed ear receivers and an attached broadcast-quality boom-mounted microphone. Designed for news and sports broadcasting, special events remote announcing, interviewing, and intercom systems the SM2 allows convenient hands-free operation.
The SM2 microphone is a close-talking unidirectional dynamic with a response from 50 to 15,000 Hz. Because of its noise reducing character, it discriminates in favor of close sounds and against distant sounds. As a result, it can be used even under extremely noisy conditions without loss or masking of the voice signal. The microphone boom pivots through 155 degrees so that the microphone can be correctly positioned at the corner of the mouth either from the left or right side. A locking thumbscrew prevents the microphone from slipping or twisting out of place.

Headphone type refers to the construction of the headphones.
Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.
Around the Neck means that the headphones wrap around the neck. This is also seen in active and sports headphones.
Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.
Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.
This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.
In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.
Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.
On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.
Corded means that the headphones use a cord to transfer the audio signal.
Wireless means that the audio signal is transmitted wirelessly to the headphones.
1/4" Stereo jack is a larger audio jack that select electronics have.
