Example Input: I'll start with why I gave it one star; the case doesn't allow the sound to get through adequately. You can hear people on speakerphone or other but your voice is muffled even if you're talking with your mouth right up to the microphone opening. I would not recommend this product unless it was re-designed. It's made well maybe it would be waterproof I don't know. Everything fits together well it's just the sound is awful
Example Output: 1

Example Input: Worked really well. Bought 2 for a 5 and 7 year old and they was able to use them without problems. Wish I would have purchased one for my wife and I.
Example Output: 5

Example Input: The inspire HR fits fine, but the clip takes away the HR function and it also doesn't track correctly. Many times I have tried wearing them while shopping and they tracked me as swimming!
Example Output:
