Key Features
The Saramonic WiTalk-WT4S is a full-duplex wireless intercom system engineered to provide clear audio and all-day wearing comfort in a true-wireless design with no hub or bodypack required. This configuration includes 1 single-ear master headset, 3 single-ear remote headsets, 4 rechargeable batteries, 4 USB-C to USB-A charging cables, and a small water-tight carrying case. The system provides reliable transmission to all the wireless headsets at a line-of-sight range of up to 1312'—making it well suited for a variety of applications, including public and sporting events, film and video production, project coordination, and much more.
True Full-Duplex Operation with Simultaneous Communication for 4 People
Unlike some intercom systems that say they are full duplex, the WiTalk-WT4S is a real full-duplex intercom system, allowing your team of up to 4 people to simultaneously communicate at any time. There are no limitations on how many people can speak at the same time, allowing your team to communicate efficiently without having to wait for another user to stop talking. The WiTalk intercom is much more powerful and effective then walkie-talkies, other two-way systems, and other full-duplex intercoms that limit your communication to 1 to 2 users at a time.
Single-Ear Headsets with Adjustable Boom Mic & Rotatable Earcup
The WiTalk-WT4S adjustable single-ear headsets are designed to be incredibly comfortable and extremely lightweight. They feature soft breathable leatherette earpads, enabling users to comfortably wear the headsets during a long production. They also feature a 270° microphone boom arm swivel, adjustable headband, and rotatable earcup, allowing users to configure the headsets with the mic on the left or right side.
Hands-Free Operation with Easy-to-Access Controls when Needed
The WiTalk-WT4S is truly hands-free, allowing users to work and communicate with ease and without reaching for a push-to-talk every time they need to speak. Whether you are a film crew with a director calling the shots, a stage team making sure the production runs smoothly, or a coaching team on the sidelines, the WiTalk lets you communicate clearly without having to worry about unneeded controls. When you need to mute your microphone, it's just as easy as flipping the gooseneck mic up or pressing mute on the remote's earcup controller. Volume adjustments are just as simple, with easy to find up-and-down buttons on the earcup controller and hub.
Intelligent Design for Focused High-Quality Sound
High-quality sound is just as important as range and comfort with intercom systems, especially when working in a noisy environment like a concert or sporting event. The WiTalk-WT4S is designed with sound quality as its highest priority, delivering high-resolution sound with a 65 dB signal-to-noise ratio and a frequency response tailored for the human voice. The microphone is designed to filter out extraneous audio, so you're not transmitting anything but your team's communication. And the over-the-ear earpads make it even easier to focus on your crew.
Extended Range and Power You Can Rely On, Indoors and Out
Operating in the less congested 1.9 GHz spectrum, the WiTalk delivers a high-quality signal and extended range, without interference. It features a working range of up to 1312' line-of-sight, giving your team the freedom to work in large venues or locations, while still in communication. A full system charge gives you an incredible runtime of up to 18 hours on the remote headsets, and 5 hours on the master headset with up to 4 remotes in use. USB-A to USB-C charging cables are included, allowing you to quickly charge the batteries in the headsets for your system, and inexpensive WiTalk-BP batteries are available (sold separately) to have more power on-hand when you need it. Each headset also features a USB-C port to power and charge the system while in use with USB battery packs or power supplies.
An Expandable System for up to 17 People
The WiTalk-WT4S system doesn't just limit you to 4 people, it is an expandable system that lets you create an intercom system for up to 17 users. The system supports up to 5 users without a hub. Replace the master headset with a WiTalk-Hub base station and an WiTalk-LBH headset (both available separately), and you can add up to 5 more remote headsets for a 9-person system. Add a second WiTalk-Hub with a WiTalk-Link cable to accommodate up to 8 more remote headsets for a 17-person system. The WiTalk is ready to equip your entire team, even as your needs grow. You can even mix and match single- and dual-ear headsets to suit your crew's needs.
