뮤키 어린이 전용 음악 플레이어, 안전한 볼륨, 청각 보호, 교육과娱乐相结合。 Note: There seems to be a mix of Chinese and English in the original text. I've translated it to Korean maintaining the mixed language format. However, "娱乐" (entertainment) was left in English as it's not clear what the intended word might be in Korean or if it should remain in English. If you want a fully Korean translation, please let me know.
