Eartec XT-4 overview

  • 1Description

The COMSTAR XT-4 4-User Full Duplex Wireless Intercom System from Eartec is a fully functional wireless intercom that offers full duplex communication in a simple design which does not require the use of beltpacks. The system consists of a Com-Center base station and four wireless headsets. Additional headsets can be added to the system, allowing you to create a wireless network of up to eight users who can all communicate simultaneously with no delay or voice activation; ideal for applications where teams need full use of their hands. You can even split users into two groups of four people, or bring everyone together in conference mode.

Each headset connects wirelessly to the Com-Center at distances of up to 400 yards in any direction, allowing the headsets to be up to 800 yards apart while still enjoying full communication capabilities. The around-ear cushions and padded headbands provide lasting comfort for all-day use. Integrated controls make it easy to adjust the volume of the headsets and program them in the field. The COMSTAR system is self-contained, so no remote antenna is needed.

Each headset has a microphone at the end of a positionable boom, allowing you to place the mic in the best spot for excellent vocal pickup. A foam windscreen reduces the effects of wind noise and breath pops for ultimate clarity. The headsets have rechargeable lithium batteries that provide up to 10 hours of operation, while the Com-Center has a rechargeable NiMH battery that provides up to six hours of operation. The Com-Center also has an AC wall plug and a battery sled for disposable AA batteries to give you additional powering options. A multi-port desktop charger is included that allows you to charge the Com-Center and headset batteries simultaneously.

The system works in the 1900 MHz frequency band, which is reserved by the FCC for "PCS" voice communication, so no license is required. The system is certified for use in the USA, Canada, Europe, and Australia.

Note: Additional headsets available separately for system expansion.

Eartec XT-4 reviews

COMSTAR XT-4 4-User Full Duplex Wireless Intercom System is rated 3.8 out of 5 by 6.
Rated 1 out of 5 by from Nothing good We bought this product because we are producing multi-camera live stream sporting events and used it for communications between our switch operator and the camera ops. Product performed terribly. It was advertised as 400 yard coverage to the comm center, but couldn't reach our end-zone camera at no more than 60 yards. We tried all the headsets from that location. Moved the comm center to field level, top of press box and mid height, all within line of sight. Still didn't work. The headsets themselves became very uncomfortable during use as well, and they have a cheap feel to them. I returned the product after the first use.

Rated 3 out of 5 by from OK HEAD SETS I use this product at my church and use them to communicate with my camera crew and sound person.This system proved to be very use-full and exactly what we needed. We were able to hear each other through the constant loud noise that goes on compared to previous brands. We never had any problems, until a month later.The headsets themselves started to break. One of the two ear headsets ears chipped off somehow. It now hangs by its wire that transmits audio through the ear. It still works but it's just chipped off. Another problem is to another headset. The microphone no longer transmits audio so that the user can communicate. I wish the headsets kept itself together. I would not have to look for another brand of intercom systems that are much more expensive than these.

Rated 5 out of 5 by from better than expected We use the Intercom when moving and docking large boats in close quarters, there is often strong winds and unpredictable effects from strong tides, being in contact with the docking crew has made this a lot easier. The Comstar are always crystal clear and the full duplex means you can have a totally normal conversation without any one missing any information, the hands free at all times is the total icing on the cake your hands are always free to continue what you are doing while you talk.

Rated 5 out of 5 by from great comms system used for first time tracking crane shoot the day was a big 15hr day comms where great for the coast i was very suprised by the quailty they are great im going to purchase another set
Date published: 2012-08-08
Rated 4 out of 5 by from Fantastic We are a local PEG channel and occassionally shoot live sporting events at the local high school. Our old headsets were never very good, so we invested in this set. The quality of the sound and the range are great. We would highly recommend these.
Date published: 2013-01-10
Rated 5 out of 5 by from Easy, Comfy, Great Quality! We use this system for communication in a church setting as we capture our services live on video. No complaints whatsoever! The set has exceeded our expectations and every person involved has commented on their quality, comfort and ease of use. We would gladly recommend this system to other customers.
