The HSC 4VXS is a completely integrated headset. A compact microphone CCM 4VXS (cardioid designed for extremely close pickup of speech) is permanently connected with the Ultrasone HFI 680 headphone via a gooseneck element.
A single cable connects to the headset. It is then split to a microphone output (XLR-3M) and the headphone input (1/4" stereo phone plug).
The headset comes with the popp screen B 5. For even greater protection against wind and popping noise, the popscreen B 5 D can be used instead.
- fully integrated: microphone, gooseneck and headphones form a unit
- highest intelligibility
- special cardioid microphone with steep bass rolloff (CCM 4VXSLg)
- effective suppression of noise from surroundings
- excellent protection from vocal “popping” sounds
- The earpiece on the opposite side can be folded out of the way of the ear.
The microphone CCM 4VXS offers a steep bass rolloff and a mild high-frequency boost. It is designed for lateral sound pickup at the shortest possible distance, i.e. directly in front of the speaker’s mouth. Proximity effect compensates for its low-frequency rolloff such that the microphone has an even frequency response for the person speaking, while background noise encounters the full response rolloff and is greatly reduced.
The HSC was developed in cooperation with professionals who expect the highest sound quality and intelligibility.
In place of the cardioid microphone, an omnidirectional microphone such as the CCM 2S can be used; the result would have a very natural sound color and no proximity effect. However, the sensitivity to off-axis noise would then be higher.
