I need some help, if there is any available, with the wireless headphones. I'm using five tones with my 800 and the wireless headphones that came with my 800 are really terrible sounding. The highs are ok, but the the lows are very muddled and or soft, muted. I've tried setting the volume up which only makes the lows sound like I'm in an echo chamber. Setting the volume down is no help either. I've tried changing the tone levels on each of the five tones areas, again to no avail. I just cannot get rid of the low 'bass' echo sound. Any help will be appreciated. If this is the best the Minelab headphones can get, I'll have to go another route. I'm using my Pro Golds with the WM08 and the sound is very good, highs and lows with no echo, but I would rather be completely wireless.
