Why schools choose Smart-Trek
- Bend-to-position microphone. The steel-reinforced gooseneck holds its place near the mouth for clearer recordings.
- Tough school cord. The 5-ft braided Dura-Cord is made to hold up to daily classroom handling.
- Inline volume control so students adjust their own level without device menus.
- Over-ear leatherette cushions that wipe clean between users.
- Labeled storage bag included. The write-on bag keeps each student's headset with their name and off the floor.
Device compatibility
Check your device: Plugs into the combined headset jack on Chromebooks, laptops and tablets, carrying both audio and microphone through one 3.5mm TRRS plug. Desktops with separate pink and green jacks need a headset splitter. For USB-C-only devices, choose the Smart-Trek USB-C version instead.
Classroom uses
- Online assessments with spoken or recorded responses
- World language, ESL/ELL and speech programs
- Reading fluency and speech-to-text activities
- Video calls and virtual lessons
