The real reason swimmers were stuck in silence—and the breakthrough that ends it
Stream Spotify and get real-time coaching underwater—no dropouts, no earbuds falling out, no MP3 hassle.

"Bluetooth has never worked for me on the pool when my phone is at the edge. It's a limitation of Bluetooth." — Real swimmer, Reddit
The Physics That Killed Bluetooth Dreams
Bluetooth runs at 2.4 GHz—a frequency water absorbs fast. Signals die within inches underwater; waves reflect off the surface like light on a mirror.
- Flip turns cut audio
- Even expensive models drop underwater
- BT only works above the surface
The $200 Million Limitation
Read the fine print: "Bluetooth connectivity not available underwater. Use MP3 mode for swimming." Swimmers have been told to load MP3s like it's 2005.
