Bulk 10-pack wired earbuds

This pack supplies ten in-ear headphones with a 3.5 mm stereo plug for classrooms, libraries and group-testing environments. Each unit is individually wrapped in OPP packaging and the assortment covers ten distinct colours for easy identification. The 1.2 metre tangle-free cable and L-shaped connector fit tablets, Chromebooks and PCs without adapters. They are built for high-volume, shared use where cost per unit matters.

Individually wrapped colour assortment

Individual OPP bags keep each pair hygienic and simplify distribution to students or test-takers. The ten-colour mix lets teachers assign a colour to a group or grade without extra labels. A 3.5 mm L-shaped jack reduces strain on device ports during frequent plugging and unplugging. Inline media controls and a microphone with approximately 3 kΩ impedance support basic voice applications.

32 ohm 85 dB limited output

The 32 ohm dynamic drivers deliver stereo playback from 20 Hz to 20 kHz at a maximum sensitivity of 85 dB, capped by internal circuitry to protect young listeners. Maximum input power is 5 mW, so output stays consistent across phones, tablets and computers. The lightweight 0.109 kg design suits extended wear but the fixed cable and single 3.5 mm connection rule out wireless use or devices lacking a headphone jack.

Questions about this item

Will the 3.5 mm L-shaped plug or the 4-foot cable need replacing first?

The 3.5 mm L-shaped plug is a standard stereo jack; the 4-foot tangle-free cable is fixed and not user-replaceable, so the plug will outlast the cable unless it is physically damaged.

What limits listening time when the earbuds are used continuously in a classroom?

The 85 dB sensitivity cap set by the internal sound-control circuitry prevents the volume from exceeding safe levels, so the limit is the fixed maximum loudness rather than battery or driver fatigue.

How much heat or noise do the earbuds produce when worn all day?

Passive wired in-ear drivers generate no audible self-noise and negligible heat; the only sound is the programme material at up to 85 dB and the earbuds stay at skin temperature.
