Recently bought this because my much more expensive waterproof Mojawa ($159.99 according to their site) were just not good when wet due to the overly sensitive touch screen like "buttons". During a 2 mile ocean swim, modes were constantly changing when I turned my head to breath so I got caught on repeat and had to listen to "Gonna Fly Now" (Rocky Theme) 4 times in a row; which is not great when you are trying to keep your heart rate down. Even Rocky has a limit on number of hurting bombs he could throw. Additionally, there are multiple touch areas that do different things that is really hard to remember when you are knocking out yards.
Swim Nerd had solved this problem with a much more simple solution: BUTTONS!!!! Yes this MP3 has real buttons that don't get pushed when the wind blows a certain direction.... and you can feel them and they click. Real simple reliable operation and plenty of volume and NO REPEAT MODE :) ; just shuffle and sequential play. Very intuitive operation the front button controls volume up and skip forward; middle modes (bluetooth, SD, shuffle, sequential, on/off); back button volume down and skip back. It even has a microphone to have a phone conversation as well. As for volume: I used them whilst cutting grass with a loud 22 horsepower riding mower and blutetooth streaming a quiet audiobook (under hearing protection earmuffs) and sweating my face off (112 F heat index that day). No unexpected skips or volume changes. Get these for your long workouts or just for walking the dog and being able to hear cars.
