The key to Walker's latest hearing protection and enhancement muffs is the use of four microphones--one mounted front and rear on each ear cup. They allow easy conversation at the range and enhanced ability to hear approaching game while in the field. Firearm blast noise is instantly reduced to a safe level. There are individual volume control knobs for each ear, and a frequency adjustment knob allows for personal tuning. The unit's noise reduction rating is 24 decibels, and maximum power output is 110 decibels. Suggested retail: $259. Walker Game Ear, 610/565-8952, www.walkersgameear.com
