Dual-mode volume limiter for young listeners

These over-ear headphones cap output at either 85dB or 94dB with a simple switch, protecting developing ears during schoolwork or travel. The 40-millimeter dynamic drivers deliver stereo sound through a standard 3.5-millimeter plug, and an inline microphone handles voice chat or classroom apps. Passive noise isolation from the cushioned cups reduces the urge to raise the volume further.

Replaces unrestricted headsets that risk hearing

The dual-limiter design removes the guesswork for parents who previously relied on software settings or adult headphones without hardware caps. When a child moves from a quiet classroom to a noisy journey, the higher 94dB mode keeps audio audible without unlocking unsafe levels. The foldable frame and 5.2-ounce weight make the swap practical for daily packing.

Wired simplicity fits any 3.5-millimeter jack device

No batteries, pairing or drivers are required — plug into a tablet, laptop, phone or in-flight entertainment system and listen immediately. The tangle-resistant cable and inline volume dial let the user adjust level without reaching for the source device. Because the headphones draw zero power, they never interrupt a long lesson or movie with a dead battery.

Questions about this item

Will the 3.5 mm plug fit a phone or tablet that has no headphone jack?

The cable ends in a standard 3.5 mm plug, so it only fits devices that still have a 3.5 mm audio socket; phones or tablets without that port would need a separate adapter.

What is the step people miss when they first put the headphones on a child?

Slide the volume-limiter switch to the 85 dB or 94 dB position before handing them over; the headphones default to the higher setting until the switch is moved.

Which parts wear out first and how are they replaced?

The ear cushions and headband padding are the only parts that degrade with daily use; they are not user-replaceable, so the whole unit is swapped when they flatten.
