Transmit buttons PTT Push-to-Talk

With our external transmit buttons, you can key the talk channel of your radio without having to touch it. This means that the radio does not have to be directly accessible and can be carried more easily on your person, e.g. in a jacket. Our buttons can either be permanently wired to the headset or supplied separately via a Nexus socket as a base unit with the desired radio plug.  Various headset tops with Nexus plugs are available for this purpose.

Talk buttons for intercom interface

PTT transmit button adapter cable for radio integration into Axiwi intercom system

This special cable allows a radio device, in this case the Motorola MTP3550, to be integrated into intercom communication systems such as Axiwi AT320 or AT350. The cable is connected to an Axiwi device via a jack plug. This allows all radio messages coming through the radio to be heard by all intercom group members on the other Axiwis. By pressing the PTT button, all conversations in the intercom group can also be sent to all other radios. The complete solution has already been delivered to several mountain rescue services.

PTT push-to-talk button for smartphones

Talk button for smartphones – PTT button for mobile phones

This robust talk button is equipped with a coiled cable with a 4-pin 3.5 mm jack plug with CTIA assignment for tablets and smartphones. It has a 3.5 mm jack socket on the top, which allows any wired mobile phone headset to be connected.

To speak, the user must press the talk button, similar to a radio. This has the great advantage, especially when used in chat rooms or for group calls on apps such as WhatsApp or Signal, that not all participants’ microphones are always open, but only when the talk button is pressed.

This ensures that unwanted voice transmissions, such as coughing, laughing, side comments or even noise, are not transmitted to all other participants in the talk group. Our TN-117-01 hearing protection headset is particularly recommended for noisy environments.

Info for tech enthusiasts: the built-in special circuit lets the smartphone know that a headset is actually connected, even though the microphone line is interrupted (when the send button is not pressed) and the mobile phone would therefore “think” that only headphones were connected without this adjustment.

Please note: the send button cannot be used as a PTT button for PTT over Cellular (PTToC or PoC) apps (such as Zello, Taasta, Wave PTX, Airbus Agnetwork, BTTALK, Buddycom, Grouptalk, Tait, Zebra, etc.). If you work with PoC apps, we can offer other solutions, e.g. one with Bluetooth. Please send us your enquiry!

This means that our adapter can also be combined with our ear microphone system or induction system, for example.
This provides a modular system that can be used for personal protection as well as for concealed wear during surveillance.


The adapter has buttons for volume control and call acceptance when making phone calls. In addition, our wireless external PTT buttons can also be used.

The talk time is up to 10 hours, the standby time up to 50 hours.

Item no.: HS-201-XX – Special version with reprogramming for PTT operation on smartphones

Bluetooth PTT handheld monophone for smartphones

Wireless Bluetooth handheld microphone speaker

This wireless handheld microphone can be used with your smartphone or tablet via Bluetooth.

It can be used as a hands-free device for normal phone calls or WhatsApp calls. The microphone is then always open and the PTT normally has no function.

However, we also have a reprogrammed special version in our range which, when the PTT is pressed, switches the microphone on as with a radio and switches it off again when released. This prevents unwanted background noise from being transmitted continuously. This is an important feature, especially for telephone or WhatsApp conferences.

The handset has a large, powerful speaker and the microphone is located on the front. On the right-hand side there is a talk button and an emergency call button, and on the left-hand side there is a volume control with push buttons. 


On the back is a large, robust and rotatable clip so that the monophone can be positioned optimally on clothing. It is also equipped with a 3.5 mm jack socket for connecting standard headphones, earphones or sound tubes.
Item no.: HS-110-22 (radio, telephone PTT)
