Why do some people fall asleep the moment they lie down, while you just can’t? Actually, many people aren’t lacking sleep — the environment is just too quiet, and the brain won’t slow down. That’s why more and more people are using a sleep speaker. Just place it under your pillow and connect it via Bluetooth. You can listen to podcasts, music, or stories with clear and private sound. It helps your brain relax and drift into sleep more easily. I basically use it every night now.
