The TW407 is similar to the TW406, but has an in-line on/off switch fitted to the cable for applications where the user needs to have conversations locally without being heard by the wireless-connected users.

The TW407 headset is terminated with a Fischer 102 Series 7-pin plug.

Suitable in applications where a discreet headset is required, and ambient noise is low to moderate, for example in a small venue or studio.

The TW407 is not suitable for use with wired Tecpro beltpacks
