DECT vs. Bluetooth: Security
Security of your wireless conversations is a natural concern DECT uses a 64-bit encryption, and Bluetooth has a 128-bit encryption. So once the headsets are appropriately paired with their base stations, the chance of someone effectively listening in on a call is virtually nil

DECT vs. Bluetooth: The Distance Difference

One of the biggest differences between DECT and Bluetooth is that DECT has a far greater range: around 100 meters (330 feet). Bluetooth range depends on which class is used:

• VT9605 has a range of about 30 meters (98 feet).

DECT vs. Bluetooth: Connectivity Considerations

Another difference is that a DECT headset can only connect to one other device –namely the base station that provides a connection to the phone network. Pair Up to 4 Headsets for Conference Call .

A single Bluetooth device can connect to up to2 other devices simultaneously. So the same Bluetooth headset could be used to connect to a user’s mobile phone,computer, tablet, and desk phone.

ENC (Environmental Noise Cancelling)：The microphone only picks up the user’s speech, eliminating the surrounding background noise, so that the other person can hear the call more clearly.

ANC (Active Noise Cancelling) is a technology that uses additional microphones (either inside or outside of the ear cup) to pick up background noise and invert it by 180 degrees. The inverted noise cancels out the unwanted background noise leaving just the original audio the user wants to hear.
