The Power Up Tube for the right ear is designed to carry sound directly to the tip and the ear. Itâ€™s virtually invisible and has enough flexibility to allow for precise positioning. The 2.5 length Power Up tube can increase amplification by 40%.
The occluded Sonic ZTip stays put without the need to readjust and unlike itchy silicone domes which can slip out of the ear canal the Sonic ZTip will always stay in place. The ZTip fits much like an ear mold but does not rely on silicone "tacky properties" for a snug fit so they stay in place all day for up to 4 months providing the most comfortable tip available. This design features natural airflow and directs sound precisely into the ear canal."
