This is the waterproof Finis Neptune; Finis SWIMP3 and the original USB charge cable.  I charged the Neptune up with the USB charge cable and one side played fine. One of the ear/jaw pieces on the other side is frayed and also at the Neptune end and I only got static ( see pics ).  The other side plays well. The other pictured set is for the underwater radio I guess, I am not familiar with Finis. This set looks in good condition but I have no way to test it. I do know that the charger works fine, I used it to charge the Neptune. I am selling the set “as is” or for repair. The Neptune has many songs ( 178 ) on it, Italian Opera, Bach, John Lennon; Andrea Bocelli; Ray Charles and many more. Please look at images and ask questions prior to bidding. I can combine shipping when requested. Buyer pays shipping; standard USPS rates for shipping insurance is added as part of the handling fee.
