Plantronics Supra H61 Headset with M22 Amplifier

• The Supra H61/M22 combo is designed for visually impaired telemarketers and sales people. The right speaker, with its attached microphone, is connected to the M22 amplifier, which in turn is connected to a phone. The left speaker is connected to the audio out jack of a computer. When a visually impaired telemarketer makes a sales pitch, he hears the prospect in his right ear and the telemarketing script in their left. The teleprompting software that displays the marketing script on the telemarketer's monitor uses TTS (Text To Speech) to convert this script to audio that the visually impaired marketer can repeat over the phone. This Plantronics combo is also useful for dictation. A visually handicapped person can hear the dictation in his right ear and listen to keystrokes in his left. If he hits a wrong key, the computer lets him know he can correct it.
  
  

Telecoil GN 2125 Headset with 8050 TCA Amplifier

• For hearing aid wearers, background noise can be a real problem since it gets amplified with the sound they want to hear. The GN 2125 headset counters this problem by suppressing background noise while boosting the headset audio hearing-impaired users are listening to. This Telecoil headset gets its name from its ability to maximize the benefits of telecoil hearing aid technology. A telecoil is a fine wire coil around a metal core that is energized in the presence of magnetic fields. Telecoil-equipped hearing aids are able to detect and amplify the magnetic signal produced by telephones and other magnetic devices. The result is clearer sound without the background noise that hearing aid microphones pick up. The GN 2125's noise-canceling boom microphone also eliminates background noise and when this headset is used with its 8050 amplifier, a telephone/computer switch makes it easy to use computer voice applications while answering phone calls.
  
  

Bone Conduction Boom Headset

• Billed as "the world's best noise cancelling headset" by the manufacturer, the Bone Conduction Boom uses passive noise cancellation to eliminate background noise without affecting the primary signal. This works better than active noise cancellation because speech and noise frequencies often overlap, and active noise cancellation filters out some speech frequencies along with the noise. The end result is reduced clarity in the remaining signal. Bone conduction is the passive noise cancellation technology used by the Bone Conduction Boom headset. Because its audio signal is transmitted by vibrating a hearing impaired user's temple, the signal bypasses the eardrums and cancels out background noise. This headset also has a powerful noise-cancelling microphone that clearly transmits quiet conversations in background noise levels above 100 decibels. Although the Bone Conduction Boom's primary application is communication radios, adapters are available for computer use.
  
  

NoiZfree XTRA Stereo Headset

• Bluetooth wireless technology has made headsets more convenient and NoiZfree's XTRA Stereo headset brings this convenience to users with moderate hearing loss. The XTRA in the name stands for extra volume, and any device that sends and receives Bluetooth signals can be used with this headset, including computers. Because NoiZfree's XTRA comes with earphones and a lapel mic, it's also comfortable to wear for extended use and its in-line, multi-function phone button with volume control puts everything within easy reach.
