I do not like to hunt with headphones,----the speker derects the sound away from the ear. -- so i made a simple sound reflector that rederects the sound right at my ear and its amazing how much better the sound comes thru tried it out tonite and i had no problem hearing the very soft threshold humm . I hate headphone cord i get all tangled up and have to be set free by passers by like a bird from a snair now with this new inovatev space age MODe i am free, It is made from a wheatys box but i am looking into better sound transmitters like aluminum or egg cartons , i was going to get a tube to go from the speker up and over and facing me O well works good Gunnar in Minnesota
