Black Box Explains...Speaker sound quality.

A human with keen hearing can hear sounds within a range of about 20 Hz to 20 KHz. But most human speech is centered in the 1000 Hz range, so... more/see it nowmost old-fashioned analog telephone networks provided audio bandwidth only in this range. This range transmits most voice information but can fail to register voice subtleties and inflections.

Because these older analog phone systems had such a narrow bandwidth, headset manufacturers built their products to operate only in those particular frequencies.

When digital networks and fiber optic connections came into use, however, they provided a much wider bandwidth for voice transmission. This led to a corresponding increase in headset sound quality.

Today, quality headsets take advantage of increased network bandwidth and typically can reproduce sounds in the 300 Hz to 3500 Hz range. This makes voices far easier to understand and enables you to pick up all the nuances and inflections of your caller’s voice. collapse


Black Box Explains...Choosing the right headset.

Black Box offers several headsets for office use. Choosing the right one for your application depends on your needs.

First, do you need a monaural, binaural, or stereo headset? Monaural headsets... more/see it nowhave only one earpiece, making it easy to have over-the-phone conversations as well as face-to-face interactions, such as in a busy call center setting (see models HS402 or 64338-31, for example). Binaural headsets have two earpieces, which are on the same audio channel (HS113A or 2009-820-105). They are great when a user needs to have long, over-the-phone conversations. Stereo headpieces also have two earpieces, but operate on distinct audio channels. These last types of earpieces are best for listening to music.

Secondly, comfort is a big factor, especially if you have to wear a headset all day. Do you want an over-the-head model? Or would you prefer to wear your headset behind the ear? Headsets with two earpieces are almost always over-the-head models (see H16N). For long-wear applications and optimum sound quality, these are a good choice. Over-the-ear models are better for in-office interactions, or for when you are on and off the phone all day (26089-11 or M140). The sound quality is still excellent, but they enable you to also be aware of your environment.

Thirdly, choose an amplifier that matches your telephone and the way you work. The Two-Prong Carbon Amplifier (HS101A) is designed for phones that have a two-prong headset port. Several headsets have amplifiers built-in, such as the Elite Call Center Headset (HS111A).

Most Black Box headsets are noise-canceling models that reduce background sounds. They are ideal for busy office environments.

We have wireless headset models, plus cords, plugs, and adapters that enable extra mobility during calls. In addition, we carry extra parts such as earhooks, ear pads, headbands, and microphone covers. collapse


Black Box Explains... Ear Capsule Positioning

Many headset ear capsules fit awkwardly in the ear and make telephone professionals uncomfortable. If you wear a headset all day, that can really affect productivity. When choosing a headset,... more/see it nowmake sure the ear capsule has a hinge on it. This design enables you to adjust the headset for all-day comfort and better productivity. collapse


Black Box Explains...Microphone positioning.

Proper microphone positioning is especially important to take advantage of noise canceling microphones, which reject background noise.

For optimum performance, position the microphone one finger width away from your lower lip.


Black Box Explains...Quick disconnnects.

A quick disconnect enables you to disconnect your headset without disconnecting your call or taking off your headset. This option is expecially convenient when you need to leave your desk... more/see it nowand keep your caller on the line. When you return to your desk, all you need to do is reconnect the plug and you’re talking again. The quick disconnect works well for call centers and busy offices where files aren’t at your desk or when you need to speak to a supervisor. collapse


Black Box Explains...Flexible microphones.

A headset featuring a flexible, swing-away microphone boom is easy to adjust—all you need to do is bend the boom until the microphone is in the correct position. Plus, you... more/see it nowcan easily swing the microphone out of your way if you wish to take a sip of coffee or soda while you’re on the phone. collapse
