I love my MMK. Problem is I have tried 3 set of underwater headphones and the volume is too low. I just updated my Simplex Plus with V2.77 and love the added volume for wired phones. I tried the previous mentioned phones on the Simplex and they are fine. Could we possibly get an update to the MMK with that extra volume levels. I think the MMK is the most underrated machine on the market. I need the extra volume, Its water season and I need to hear the beeps
