TEControl has now introduced a new headset that's designed to be flexible to let you bend it to a comfortable shape, yet still springy enough to stay in place on your head. It includes a Yamaha BC3a type mouthpiece, with adjustable bleed.
The mouthpiece can be rotated away from your mouth when you are not using it. The silicone tube delivered with the USB MIDI Breath Controller connects directly to the headset.
Many synthesists find breath controllers especially useful when working with brass and wind virtual instruments.
