The brand new KX-NT680 and KX-NT630 telephones are now available for the KX-NS700, KX-NS700G, KX-NS1000 and KX-NSX2000 systems. Please note that you have to upgrade your system to the latest revision level (7.0 for KX-NS and 4.0 for KX-NSX) in order for them to be compatible.

Both models feature High Definition Audio, and the KX-NT680 is also Electronic Hook Switch compatible and has built-in Bluetooth. If you are not using PoE, an AC adapter is needed.
