Ouvir música de fones o dia todo: é pecado no judaísmo?

Judaism has an ambivalent, rich relationship with music — the Psalms are a synagogue's engine, and 'serve the LORD with gladness... with singing' (Psalm 100:2) makes song worship — but the tradition also legislates presence. Hillel's colleague R. Hillel? — the Mishnah's rule — 'do not separate yourself from the community' (Avot 2:4) — was taught about shared burdens and joys, and contemporary rabbis apply it to the headphone-wearing family member who is physically at Shabbat dinner and functionally elsewhere. The havdalah instinct runs the same direction: Judaism trains distinctions — sacred and ordinary, together and alone — and a permanent private soundtrack flattens them. On the device itself there is no ruling; on music, authorities range (Maimonides' strictness about levity vs. the Hasidic embrace of niggunim), but most contemporary poskim treat listening as permitted with content care. The practical Jewish counsel is schedule-shaped: music for walking and working, silence for learning and family, and song — out loud, together — for Shabbat, when the headphones come off precisely because the point is to hear each other.
