Experiencing difficulty hearing audio clearly while outdoors can be frustrating. Here are some steps to help you optimize your listening experience with the earbuds:

1. Ensure that your earbuds are properly worn, as the incorrect placement will affect your listening experience. The closer the speaker is to the ear canal, the better the sound quality.

2. Increase the volume.

Notes: 

1. To achieve the highest volume output on some Android phones, ensure both your phone and earbuds are set to maximum volume.

2. Open-ear earbuds help you stay aware of your surroundings but don't offer noise cancellation, which makes them susceptible to ambient noise. In loud environments, the listening experience may be affected, so using them in quieter places can provide better sound quality.
