When I call someone, they can’t hear my voice clearly. Meaning, the outside sound is very noisy.
We’re really sorry to hear that your voice isn’t coming through clearly during calls — we understand how frustrating that can be. 
Please try the following suggestions:
If you’re using only one earbud, make sure to place the other earbud in the charging case and power it off.
Turn the volume up, and try using the right earbud, as it acts as the master mic.
Test your earbuds with a different Bluetooth device and in another environment to see if the issue persists.
If you’re in a noisy environment, speak a bit louder — background sounds can interfere with microphone clarity.
Let us know if these steps help!
