What should I do if the sound quality is poor when using Sleep A30 in Bluetooth mode?
1. Try different sizes of ear tips and adjust the earbuds to ensure a snug fit in your ear canal.
2. If one side feels less secure, you can mix sizes (e.g. medium on the left and large on the right) to achieve a better fit for better audio quality.
3. Try playing different types of music and ensure the audio file is free of distortion or noise.
4. Clean the ear tips and metal mesh filter and try again.
