Model 1025MUSB | NeoTech™ Series Headset
Durable CaliTu™ Cord
The 1025MUSB features a highly durable CaliTu™ cord made 
of braided, PVC-jacketed material that resists chewing and 
cutting. The CaliTu™ cord design includes a reinforced earcup 
entry point that resists stress separation and a tethered Velcro 
strap that provides cable management for easy storage. 
Hygienic Packaging
The 1025MUSB comes in a heavy gauge plastic zip lock bag 
that promotes classroom hygiene by isolating head lice while 
providing utility for storage when not in use.
Specifications
The NeoTech 1025MUSB is an attractively-priced, mainstream, 
mid-weight headset for general-purpose classroom usage. The 
1025MUSB delivers performance at a cost-eective price for 
1:1 learning, assessment testing and more. Its audio playback 
is calibrated to enhance the tonal range of the human voice 
in language learning and its noise-reducing boom microphone 
captures a student’s verbal response - not their neighbors, making 
it ideal for language learning, library uses and in computer labs.  
Compatible with Chromebooks, laptop and desktop PCs 
& Macs, it provides the versatility you need for BYOD and 
school-issued device requirements in the classroom.

3-Year Institutional Warranty

damage sustained in classroom settings. This added level of protection helps stretch your budget by covering replacement costs if necessary 
in your particular situation.
