Model 35IR-B

1.  Fully adjustable comfort strap wrapped with leatherette 

cushioning to fit all sizes

2.  Recessed wiring resists prying fingers for classroom safety

3.  Replaceable foam-filled ear cushions

4. Volume control

5. On/off switch

6.  Noise-reducing earcups lower ambient noise so volume does

not need to be as high, as recommended by  audiologists

7.  Built-in wireless receivers (semi-circle considered ideal for

group reception)

8.  Rugged ABS plastic headband and earcups for durability

• Warranty for school use - unlike headphones purchased at a

consumer electronics store whose warranty is voided if used

in schools

This stereo headphone is ideal for assistive

listening with shared computers in labs,

libraries, classrooms and language learning

situations. It can also be used as a teaching

resource in ed tech applications. This wire-

less headphone allows added students to

join existing groups who are already using

a Califone 35IR-USB or 35IR-PLC system

and does not include the USB transmitter

which is needed for independent use.

Please contact us immediately if you experience any issues or

questions with your headphone. Our “Project Intercept" 

customer service program will quickly repair or replace items

under warranty. Simply contact us via phone or email
