• Extremely lightweight for easy student use and quick storage.
• Simple wired setup avoids pairing issues and works well for shared classroom sets.

Compatibility and connection

These earbuds use a standard 3.5 mm stereo plug and work with most Chromebooks, laptops, tablets, and desktops that include a headphone jack. For USB-C-only devices, a USB-C to 3.5 mm audio adapter may be required if permitted by district IT.

Best use cases

• Everyday classroom listening (lessons, videos, apps)
• Read-along and literacy programs
• Student take-home kits needing low-cost, portable audio
• Media labs or libraries where open earbuds are preferred

Classroom notes

• No microphone: This is a listening-only model. If students need to record speech or join calls, choose a headset/earbud with mic.
• Open earbud fit: Does not seal the ear canal, so it lets in more ambient sound than in-ear silicone tip models.
• Included accessories: Supplied with a pair of spare earpads.
