3/$30 Mercury pro sound true wireless headphones mi-E027t

These were used once have been sanitized. My daughter lost her AirPods so I bought some less expensive earbuds for her. She used once and said she didn’t like the sound. I tried them and thought they were fine, but I’m not an audiophile. These are not $300 AirPods so of course the sound isn’t going to be as good! I just went online to learn how to connect.
