RTS presents next generation of lightweight headsets dedicated to critical communication applications

September 15, 2017
  • Successor of PH 44/88 series headsets with single sided (LH-300) and dual-sided (LH-302) models
  • Meets all intercom needs requiring highly reliable connectivity
  • Unsurpassed wearing comfort with high quality audio and increased durability
Amsterdam, September 2017 - RTS intercoms is expanding its portfolio: The new LH-Series headsets by RTS are the ideal choice for all day-to-day critical communications applications that require field-proven technology and long term wearing comfort. They are the next generation of the successful PH-Series headsets, from RTS extremely lightweight and offer users a highly reliable and flexible communication tool.

Optimized for RTS intercoms

The LH-Series headset models are optimized for seamless operation with all existing RTS intercoms such as the latest ROAMEO wireless intercom system as well as all KP-Series and other RTS keypanels. Different connector type options (XLR, 4-/5-pin, male/female and 3.5 mm audio plug) ensure the greatest flexibility allowing the headsets to be utilized in virtually any kind of application. The new headsets excel in providing superior audio quality and intelligibility.

Improved comfort features and increased durability

The new headsets offer a range of improvements for enhanced usability and durability. A new microphone boom design provides stronger rotation stops and the headband-to-glider joint has been made more robust. The rotator pins of the headsets have also been upgraded with heavy-duty stainless steel improving the feel of the ear cup’s rotation. Furthermore, a pre-coiled overhead cord has been added to reduce the strain on the cord and prevent it from catching on other objects or touching the skin. An added yoke provides enhanced comfort by allowing ear cup movement in all directions. This reduces pressure points by distributing and balancing pressure over the entire ear. A soft headband pad further improves wearing comfort. Both new models come with replaceable leatherette ear cushions including speaker protection cloth for added hygiene and durability. An acoustic limiter protects users against sudden increases in sound levels.
The new LH-Series headsets are available worldwide now.
