Classroom 10-pack wired earbuds

Ten individually wrapped earbuds with 3.5 mm L-shaped plugs arrive in mixed colours for group distribution. The 32 ohm drivers and 85 dB sensitivity are capped by sound-control circuitry at 85 dB maximum output. A four-foot tangle-free cable connects each unit to tablets, Chromebooks or PCs. No microphone or inline remote is included.

Bulk packaging and volume limiting

Each earbud ships in its own OPP bag, simplifying hand-out and storage for schools, libraries and test centres. The built-in volume limit protects young listeners from excessive levels without external software. Mixed colours allow quick visual identification between users. No carrying case, adapter or cleaning tool is supplied.

3.5 mm analogue limits

The stereo 3.5 mm jack restricts use to devices with a matching socket; newer phones lacking the port need a separate adapter. Passive wiring means no active noise cancellation and no digital signal processing. Maximum input power is 5 mW, so amplifier output must stay low. Cable length is fixed at four feet and cannot be extended.

Questions about this item

Do the earbud tips need replacing after classroom use?

Each pair is individually OPP packaged and sold as a bulk 10 pack, so worn tips can be swapped for a fresh set from the pack.

Will the 32 ohm impedance limit volume on school tablets?

The 32 ohm rating and 85 dB sensitivity are matched to standard 3.5 mm ports on tablets and Chromebooks, delivering full output without extra amplification.

Does the four foot cable add noticeable weight during all day wear?

At 0.109 kilograms total the earbuds stay light enough for extended sessions, and the tangle free cable prevents snagging.
