LimitSound
Your Mac has no Headphone Safety. LimitSound fixes that.iPhones warn you when you listen too loud. Macs don't — there's no volume limit, no dB ceiling, nothing between your ears and 100% volume. LimitSound brings that missing protection to macOS.How it worksPick your maximum level (75–100 dB, the same scale iOS Headphone Safety uses). When your AirPods — or any Bluetooth headphones — connect, LimitSound caps the volume to match. Try to push past the limit and it snaps right back, instantly.✓ Works with AirPods, AirPods Pro, AirPods Max — and optionally every Bluetooth headphone (Sony, Bose, JBL…)✓ Instant, event-driven limiting — zero background CPU, zero battery impact✓ No microphone access, no data collection, no account✓ Lives quietly in your menu bar✓ Launch at login — protection survives every reboot✓ Free updates forever, delivered in-appWhat you're buyingA license key, delivered instantly with your purchase.
