The Pro Hear II really steps up the game with a 12 band gain adjustment, three layered noise reduction and advanced adaptive feedback cancellation to add up to 22 dB of added stable gain. All of that means that you get the ability to hear the faint sounds you could not hear before with incredible clarity and focus while still protecting your hearing from loud or impulse sounds. The two channels are programmed to be responsive to a wide range of noise intensities, something you cannot get with other two channel BTEs. The Pro Hear II is truly the hunters best friend.
