When using a Bluetooth headset in a call center, there are factors that can affect call quality compared to wired headsets. Here are the main factors:
1. Wireless Interference and Latency
The 2.4GHz frequency band is likely to interfere with Wi-Fi, mice, keyboards, etc.
Interference can increase the possibility of voice latency, dropouts, and distortion.
BLE (Bluetooth Low Energy) has greater latency, making it unsuitable for call center use.
2. Battery Status and Power Management
Bluetooth headsets may experience degraded transmission quality when battery levels are low or may disconnect.
Some devices may experience no audio output during initial call connection due to entering power-saving mode.
3. Operating System/Softphone Bluetooth Device Handling
Windows, macOS, and some softphones (SIP Clients) may not recognize Bluetooth devices as the default device or may take time to recognize them after connecting.
Immediately after the call connection, there may be a 1-2 second issue where the microphone or speaker does not work.
4. Risks of Multi-Pairing
If a device is simultaneously connected to multiple devices (e.g., laptop + mobile phone), there may be audio switching issues, dropouts, and malfunctions.
There is a possibility of receiving notification sounds from other devices or switching connections during a call.
Bluetooth headsets can affect call quality for the reasons mentioned above, so we recommend using USB headsets.
