Product Q&A


In the description it says you can pair more headsets with the base, what headsets are compatible? Can you supply another set of the CL75000 headphones without the base? Thank you

Sarabec's Reply:

Only the CL7500 headsets are compatible, however, they are not available separately, you would need to purchase a complete second system.
