What are the Different Frequencies of the Wireless/Cordless Devices?

Updated by Hayden Everly on Jul 16, 2024

When it comes to wireless communications, there are a few different frequencies you can be set to. Typically a headset will have one frequency it uses, not allowing you to switch to others. This is completely normal! Below is a breakdown of what headsets use which frequencies and what benefits or drawbacks each one could have.

Headsets at every frequency

900MHz - Used in many wireless systems, including cordless phones which can reduce headset range. (CS50 (DISCONTINUED!))

2.4GHz - Used in Bluetooth products, wireless network systems, and cordless phones. (CT12 (DISCONTINUED!), GN9120 (DISCONTINUED!))

1.9GHzB - Newly approved frequency band for North America dedicated to telecommunications. (CS55, CS55 Micro, CS70 (DISCONTINUED!), CS351/361 (DISCONTINUED!), OfficeRunner, DWPro1 and DWPro2, CS500 Series, AT&T Marathon, CT14 (DISCONTINUED!))
