Learning Headphones Benefits
Product description

Introducing the Koss SPARKPLUG VCk Earbuds — a compact, high‑performance audio choice crafted for learning environments, labs, and student desktops. These earbuds combine noise‑isolating foam cushions, an in‑line volume control, and a wired 3.5 mm connection for immediate compatibility and simplified setup.

Why classrooms like the SPARKPLUG VCk

  • Memory‑foam urethane earpads that mould to each ear and help block ambient noise — ideal for busy labs and shared spaces.
  • In‑line volume control lets students adjust audio levels without leaving their seat or fiddling with the device.
  • Standard 3.5 mm plug offers broad compatibility with desktops, laptops, Chromebooks, media carts and learning stations.
  • Compact and lightweight design means easy storage and hand‑out use in classrooms, testing settings, and mobile setups.

Compatibility

The SPARKPLUG VCk uses a standard 3.5 mm stereo plug compatible with desktops, laptops, audio carts, tablets with headphone jacks, and most school audio systems. It is not wireless or USB‑C native unless used with an adapter.

Care & Hygiene

For shared use in classrooms: wipe the foam earpads and cable with school‑approved disinfectant wipes between uses. Allow earbud surfaces to dry completely. Store in a labelled, clean container. These earbuds are individually packaged which helps maintain hygiene in multi‑user environments.
