Caliber Stereo Transcription Headset with Inline Volume Control and Stereo/Mono Switch Works Great With Cassette or PC Transcription - Whether you transcribe with a cassette machine or use PC transcription, the Caliber transcription headset with its stereo/mono switch makes transcribing a breeze. When using the PC, simply select "Stereo" on the in-line switch. When it is time to transcribe for that one client you have left using tapes, simply move the switch over to "Mono" and enjoy the same enhanced sound quality you've come to expect - all without buying a separate headset. Weighs in at Less Than 1 Ounce - While it's hard to believe, the new Caliber headset is 10% lighter than the previous generation. It is made with a unique nylon cord and high quality plastics and still offers in-line volume control and a stereo/mono switch. Transcription Headset or Home Theatre - While the Caliber may not reproduce sound quite like a home theatre system, it does offer substantially improved sound quality with all new speakers, improved wiring design and repositioned ear buds. With specialty-tuned speakers to help reduce bass, those deep voice dictators just got a little easier to hear. Built For Long Lasting Durability - Caliber is a professionals' headset designed to be worn all day long and offer a long lasting life. The ultra-durable nylon cord stands up to chairs rolling over it and drawers closing on it. The improved plastics and adhesives stand up to professional use day after day after day. Caliber includes a 90-day warranty. Stays Put and Reduces Static Electricity - The included cord clip helps you position Caliber and the cord right where you want it. The nylon cord doesn't bunch up like rubber cords do and it doesn't grab onto your clothes, creating static electricity.
