• Tunable diaphragm: Hear high or low frequency sounds by slightly adjusting pressure on the chest piece.
• Dual-lumen tubing: Two sound paths in one tube eliminates the rubbing noise of traditional double tubes.

• Headset is easily adjusted for individual fit and comfort. Angled ear tubes align with ear canals.
• Seven-year warranty provides greater peace of mind.
