my take on my mxsport.i got the one [ used] with the waterproof headphones .I have been swinging a dfx for eighteen years I like the sport other than its heavy .but I can handle that .the waterproof headphones, pardon my expression, well their not very good . I believe the new price on them or around 130.00.well I have a pair of their cheapest land phones that I won in a hunt ,they cost about 30.00.and to me they sound the same. now my question. has any mxsport owners that have used, waterproof headphones had the following problem? I cant raise the volume of the detector over 20.if I do the audio breaks up over a target.i thought at first it was the detector ,but then I removed the phones and I raised the volume wide open and every thing was fine.I hope whites, to whom ive always liked as a company ,will correct this problem and come out with a much better headphone.and I hope they will replace my phones.
