## Description

Product description Eartec UltraLITE HD - Full Duplex Wireless Communication Without A Base Station When your job calls for split second coordination, look to UltraLITE-HD self-contained headsets for hands-free, full duplex wireless voice contact. These revolutionary headsets eclipse all other full duplex systems for performance and convenience as the transceiver is built right inside the ear cup. Instantaneous Communication AutoMute Technology Ready to Use At the heart of the UltraLITE HD system is a specialty MAIN headset that relays the digital signals generated by up to four REMOTE units, allowing up to 5 people to talk simultaneously and hands-free. The flexible gooseneck microphone boom assembly swivels 270 degrees to be worn on either left or right, and an internal switch will automatically mute the headset mic gain when set to the UP position. UltraLITE HD are ready to use right out of the box. To operate, simply turn the headsets “ON” and talk! Featuring 5 volume settings with audible tones to denote the headset volume level. No Wires or Base Stations Required Water Resistant Deluxe Padding Hands-Free Communication Field Replaceable With the transceiver built right inside the ear cup, this self-contained, “All in One” design eliminates wires and belt worn radios. No complicated base stations or beltpacks required! Eartec UltraLITE HD headsets are silicone sealed for use outdoors in inclement conditions. Featuring an adjustable padded headband, UltraLITE HD headsets fit firmly, yet comfortably, for an 8-hour work shift. Designed to streamline communications in many industries, including food service, catering, kitchen / restaurant staff, boating staff / crew, sports coaches / assistants, and more! The Lithium Polymer batteries (included) charge externally and are field replaceable. This allows you to purchase spare batteries to keep on hand during your important events! What's Included UltraLITE HD MAIN Headset Each UltraLITE HD headset system includes a MAIN Headset. The MAIN headset must be turned on to link the corresponding Remote headsets. Its programming button is located above the volume controls and is recessed to protect against accidental activations). Only one MAIN headset can be used per system.

The Remote headset pairs to the MAIN headset in the system, providing hands-free, full duplex performance. Available in Single Ear cup or Dual Ear cup styles. 10-Bay Battery Charger The 4-User UltraLITE HD intercom systems includes a multi-charger with AC adapter that charges up to 10 individual batteries in their own bay. When each battery reaches full charge the corresponding LED turns from red to green indicating that the battery is ready to go. This feature allows users to have extra batteries on hand in the charger whenever necessary. Rechargeable Li-Poly Batteries Included Batteries All UltraLITE HD transceivers come complete with a Lithium Polymer rechargeable battery. The batteries are also available separately as replacements.

Review: Amazing Customer Service - Fabulous Product - This review is long overdue. It will be long, but follow it to the end to see why they got 5 stars... it should be more! I purchased the system for when we are boating. We spend the summer on our boat in remote areas of Canada and my husband uses hearing aids so docking conversations sometimes get loud, if you know what I mean. Our boat is over 50' and in windy conditions it gets challenging to dock. This system was recommended by friends. When we received the system I charged it and we tried it in our home and it seemed to work perfectly. We used it successfully twice then it started not pairing and it got very frustrating. I had never used the system before and so didn't know what I was doing wrong or if it just didn't work good. Keep reading, things get better. We were finally at a little tiny fishing lodge in BC that had wifi for guests so I contacted desertcart. A great kid walked me through all the steps but it still would only pair every second or third try. He told me how to get in touch with EarTec. I emailed and I think in less than 2 hours I had a response! We connected by phone, then. Same day! There is a 3 hour time zone difference so I was thrilled. I talked to an amazing person named Scott. We again went through all the steps and he said I was doing everything right and they would ship me a new set with a return label to ship the set I had back. The only problem was that we were on our trip for another 6 weeks. But we had family flying up to join us in a month. He said he would ship anyway and I could return the others when we got home. Really? He trusted me? Well, due to a family medical emergency I had to fly home for a week and the new set came while I was home. Great timing. Man, what a difference! The replacement set is awesome and works so well. It is much clearer to talk and it pairs correctly every time. Scott emailed me several times and was probably the best customer service person I have talked to and worked with in years. The company stands by its product, is responsive and I recommend the company and this product to everyone!
Review: Absolutely worth the price!! - We purchased these headsets after trying over and over with 2-way and other radios to have a communication solution in our side by side. The price tag kept scaring us away but we finally broke down and bought them after talking with a product rep and finding out they would be OK for use in the dirt. They are FANTASTIC! Not only are they comfortable (which is a big statement coming from me since I have nerve damage near my ear and in my neck so even comfortable sunglasses are hard to find) but they block out much of the external noise and the noise cancelling mic works great! We can easily talk with each other without having to push a button and the transmission is extremely clear. Add to it that there are no cords to deal with and these headsets are total winners! We love them!!
