To use headphones without sound leaking out, you can try using over-ear headphones instead of on-ear or in-ear headphones, as they provide better sound isolation. Additionally, you can invest in noise-cancelling headphones, which can help reduce sound leakage. Adjusting the volume to a moderate level can also minimize sound leakage. Finally, consider using headphone amplifier or equalizer to fine-tune the sound and reduce the chances of sound leaking out. **
