Works excellently as stated.

This is a great product. I recommend it.

These are the top earphones for outdoor sports. Perhaps "bonephones" is a better term? They deliver clear audio even in loud places, while still allowing you to hear what's around you. The build quality is excellent, suggesting a premium product. Ideal if you're exercising outside by yourself. They're light, comfortable, practical, safe, and sound great. You'll need to adjust to the minor vibrations, but it's not a problem. Highly recommended.

The microphone's audio input is very quiet, making it impossible to use for communication.
