Classroom 30-Pack Overview
This set provides thirty wired on-ear headphones with integrated microphones for school or home use. Each unit uses a 3.5 mm jack for broad device compatibility. The bulk quantity suits classroom testing, language labs and group listening activities.
Build Integration
The 3.5 mm connector plugs directly into most phones, laptops, tablets, CD players and fitness equipment without adapters. Wired operation removes the need for charging or pairing, freeing up USB ports and Bluetooth bandwidth for other peripherals.
