Hey guys,I have a gpx 4500 and I've used it for several years. I use the killer b wasp headphones and they work great but in the woods the cord gets tangled quite a bit. So,I'm looking for wireless headphones and figured someone on here may be able to point me in the right direction. Are the Grey Ghost wireless headphones good? I only hunt for civil war relics if that matters. Any help will be greatly appreciated!
