When I started this crazy Sport 5yrs ago, I got a cheap pair of freebies the dealer threw in to sweeten the pot...so I wore them slap out and found some stuff, then I got another pair of freebies and wore those out too. Then this year I finally got a set of GG NDT's, and the difference is remarkable! Tones, comfort, quality etc...
This subject often comes up and makes for good Wintertime chatter, the old guys will pipe up and tell you to definitely get some good ones right off the bat, I would now agree...Saying all this, as we get older and our hearing degrades, you sure do need a good set you can balance the tones with between your ears...comfortable, etc...
Seems the 'quietest time' to hunt is in the early hours, as the day goes on, theres a whole lot of white noise emitted by the Planet, so a good set of phones will help you immensely if you are hunting during the latter part of the day...
This is an 'Audio' based form of hunting, and you cant find what you cant hear, nice and crisp, so yes, good phones will pay for themselves in the long run.
