The wires do look a little fragile, but no problems so far.

The wire inside the casing breaks right at the end of the micro jack bulkhead

I have tried multiple other waterproof earbuds (audio flood...) but they have all failed with cheap wiring after less than 3-6 months.

They have short wires designed to connect to the waterproof Ipod Shuffle that clips to the back of your goggles so the wires don't get tangled or caught while swimming.

This was a replacement of two others that my kittens had gotten ahold of and easily bitten through a pretty fine and delicate ear wire and though they sounded good the sound is too subject to falling out and water in your ears and then, forget listening easily to music while doing laps.

Poor quality wires, which fray after regular use in 6 months or so.
