Ceotronics CT DECT Base Headset

Ceotronics CT-DECT headphones offer you many possibilities to communicate over short distances. All participants will be able to communicate with total wireless freedom and Full Duplex which means they can speak and listen simultaneously at all times.

Communication systems

The use of wireless communication systems involves even more positive aspects of occupational safety. Shorter waiting or response times generate fewer costs and the fact of giving up the cable implies greater freedom in the work area. In turn, this helps reduce the risk of lightning strikes and the danger of tripping and the consequences associated with the repair costs of damaged cables.


The headsets are part of a DECT communication system, in which the system allows us to communicate a group of 5 people in Full Duplex. To do this, you must have at least one base headset and one standard headset. The base headset provides a link of 4 standard headphones to create communication groups. You will enjoy permanent communication with your team.

The headphones have a hearing protection thanks to the radio transmission of the voice that is collected with a special microphone that compensates for noise.


This advantage for your safety will allow you to perceive ambient noise or warning signs, even though the headset is soundproofed. To avoid hearing damage, these ambient noises are automatically reduced to 85 dB. Therefore, these headsets do not pose a health hazard.

The Ceotronics CT DECT headphones have a high-performance rechargeable battery, provides the necessary voltage to operate the headset.

The communication systems of Ceotronics CT DECT, are versatile and respond individually to the needs of various industrial sectors such as the construction of machinery, the automotive industry, aviation.
