I read multiple reviews of the Eartec UltraLITE Headsets prior to purchasing. My first impression after unboxing was that these feel more like a toy than a production environment tool. The $22 battery replacement cost also is a bit of a red flag. It's a proprietary battery so third party batteries aren't an option. In the past I've had to rely on hand signals or my production team members actually paying attention to move from live interviews to prerecorded scenes during livestreams. Not anymore. These simply work, despite their amateur appearance. Since they operate on the 1.9 GHz spectrum, I've never experienced dropouts or interference when in use. You can't toss them around like regular headphones. They not as well built as headphones. Keep them in the protective case when not in use and remove the batteries as recommended when not in use. I'm sure other companies make a better built headset, but at a much higher cost. If you treat them with care and follow the recommendations, these should provide you with several years of worry-free operation.

Does this system have the ability to communicate with any EarTech Walkies as well? I want to mix headsets and walkie talkies with my crew, is this possible with these headsets?

Can you use different frequencies?

Can you use different frequencies?
Asked by: Edward
All of the headsets are set to the same frequency, but there is a range of frequencies between 1920 – 1930 MHz available. UltraLITE systems utilize a master headset and all of the others are satellites, with the system being full duplex, for two-way communication between all users.
