The sound is clear, the battery life is lengthy, they are definitely durable and are made to take drops and withstand gravity checks

Clear sound.

We're using these as a version of an intercom (mainly to communicate with our 13 year in and around the house) and they work beautifully- crystal clear sound, great range, and there's no weird "glitches" where they shut themselves off randomly or any issues with any interference

I was able to test it in a Las Vegas hotel and the sound was perfectly clear at 19 floors

Great quality and sound at a long distance.

Sound is loud and clear and the controls are water resistant and easy to use.

Great clear sound and works out pretty great distance for me
