Greetings from Grand Lake Oklahoma! I along with the " lion's share" of L.C.O's have used various types of ear protection. From foam pluggs to bulky plastic cased head band types. They all serve their purpose and do their job. However, I purchased a 60 gig I-pod last year and also went a step further and upgraded the "stock" ear phones to some after market SHURE EC2 headphones. The I- pod can hold more music than I probably will ever have! The shure sound cancelling head phones are Amazing! I realize that there is a safety issue with any kind of sense deadening equipment, As attentiveness to ones surroundings is fudamentally key. There just seems to be a profound positive effect on productivity,and attitude associated with the use of this equipment! I wear these things even when I'm digging or pick axe-ing whilerepairing irrigation systems! Hard Work, simply just doesn't seem as hard when I'm wearing them! As with anything, moderation is the key, just be carefull and focused on the job and surroundings while listening to your favorite tunes! They simply add a spring to my step and a smile to my face! ............Just remember , embarassment quickly ensues as your valued client catches you in a spirited "Air Guitar Solo",while managing their estate! Good Times!!!!!!
