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: Purchased for Datacenter and works well in that environment - After searching for a while, we bought a set of these for use in a datacenter environment. They provide a moderate amount of noise suppression with the over the ear model. The microphones pickup some of the ambient fan noise but you can push the mic upwards and it automatically mutes. This feature allows for quiet when not collaborating with someone in the datacenter. Battery life is good and overall happy for the price and performance of these headsets. ## Features - REAL-TIME WIRELESS INTERCOM FOR 4 — Have a true crew-wide conversation without pressing a button. The Eartec UL4D full-duplex wireless intercom system lets 4 users talk and listen at the same time, hands-free, the way you'd talk in person. - DECT 6.0 INTERFERENCE-FREE WIRELESS — Operates on the 1.9 GHz DECT band for clean, secure audio that won't compete with Wi-Fi, Bluetooth, or two-way radios. Up to 1,000 ft line-of-sight range, no FCC license required, and no base station needed. - DUAL-EAR DESIGN FOR FOCUSED AUDIO — Both earcups deliver clean audio and passive isolation from surrounding noise — engine rooms, UTVs, mixing booths, control rooms, and anywhere ambient sound competes with what you need to hear. The noise-cancelling microphone pivots into position and auto-mutes when pivoted upward. - PLUG-AND-PLAY OUT OF THE BOX — Pairs in seconds. No programming, no base station, no software. Each headset has its own electronics and rechargeable lithium battery — up to 6 hours of talk time per charge. Field-programmable, expandable up to 5 users. - BUILT FOR LOUD AND AUDIO-CRITICAL WORK — In daily use by audio engineers, FOH mixers, broadcast directors, control room operators, video editors, marine crews, UTV and off-road teams, equipment operators, and crews working around generators, machinery, and high-noise environments. - PROFESSIONAL AUDIO, AMBIENT PROTECTION — The noise-cancelling microphone delivers clear voice while the dual earcups passively block surrounding sound. Padded construction supports long shifts behind the console, on the boat, or in the cab without fatigue. - U.S. COMPANY, U.S. SUPPORT — Eartec is a U.S.-based professional communication brand with direct manufacturer warranty and U.S.-based customer service. When you need help, you reach people in your time zone — not an overseas reseller. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01LOKUSOC | | Additional Features | Full Duplex, Noise Cancellation, Rechargeable Battery, Wireless | | Age Range Description | Adult | | Antenna Location | Video production, Stage production, Boat operation, Drone operation, Construction sites | | Audio Driver Type | Dynamic Driver | | Battery Average Life | 6 hours | | Best Sellers Rank | #447 in Telephone Headsets | | Brand | EARTEC | | Brand Name | EARTEC | | Built-In Media | Headsets, Batteries, Charging Station, Protective Case | | Cable Features | Without Cable | | Color | Gray | | Compatible Devices | Wireless Communication Devices Operating on 1.9 GHz Frequency | | Connectivity Technology | Wireless | | Control Method | Touch | | Control Type | Button Control | | Controller Type | Button | | Customer Reviews | 4.3 out of 5 stars 102 Reviews | | Ear Placement | Over Ear | | Earpiece Shape | around_ear | | Enclosure Material | Plastic | | Form Factor | Over Ear | | Frequency Range | 1.9 GHz | | Headphone Folding Features | Over Ear | | Headphone Jack | No Jack | | Headphones Ear Placement | Over Ear | | Headphones Jack | No Jack | | Item Weight | 4.5 pounds | | Manufacturer | Eartec | | Model Name | UL4D UltraLITE-HD | | Model Number | UL4D | | Noise Control | Sound Isolation | | Number of Items | 1 | | Specific Uses For Product | Video production, Stage production, Boat operation, Drone operation, Construction sites | | Style Name | Professional / Practical / Industrial | | Theme | Wireless Communication | | UPC | 642892764587 | | Unit Count | 4 Count | | Water Resistance Level | Water Resistant | | Wireless Technology | RF | ## Product Details - **Brand:** EARTEC - **Color:** Gray - **Ear Placement:** Over Ear - **Form Factor:** Over Ear - **Noise Control:** Sound Isolation ## Images ![EARTEC UL4D Ultralite HD Wireless Intercom Headset System, 4-Person Full Duplex Communication, Dual Ear, Up to 1000ft Range — Professional-Grade, U.S. Company - Image 1](https://m.media-amazon.com/images/I/614cgKYFaHL.jpg) ![EARTEC UL4D Ultralite HD Wireless Intercom Headset System, 4-Person Full Duplex Communication, Dual Ear, Up to 1000ft Range — Professional-Grade, U.S. Company - Image 2](https://m.media-amazon.com/images/I/71FcK0ms8sL.jpg) ![EARTEC UL4D Ultralite HD Wireless Intercom Headset System, 4-Person Full Duplex Communication, Dual Ear, Up to 1000ft Range — Professional-Grade, U.S. Company - Image 3](https://m.media-amazon.com/images/I/81h8vorzndL.jpg) ![EARTEC UL4D Ultralite HD Wireless Intercom Headset System, 4-Person Full Duplex Communication, Dual Ear, Up to 1000ft Range — Professional-Grade, U.S. Company - Image 4](https://m.media-amazon.com/images/I/71MegCUBI6L.jpg) ![EARTEC UL4D Ultralite HD Wireless Intercom Headset System, 4-Person Full Duplex Communication, Dual Ear, Up to 1000ft Range — Professional-Grade, U.S. Company - Image 5](https://m.media-amazon.com/images/I/811Y1HkaeFL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing Customer Service - Fabulous Product *by M***Y on October 28, 2019* This review is long overdue.

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!! ## Frequently Bought Together - Eartec UL4D Ultralite-HD 4-Person Full Duplex Wireless Intercom Headset Communication System, Dual Ear Headsets, Up to 1000ft Range, U.S. Company - Eartec 3.7V Rechargeable Lithium Ion Battery for Ultralite headsets and HUB Stations (LX600LI) - Eartec ULSR Ultralite HD Single Ear Add-On or Replacement Remote Headset, HD Version Only, Full Duplex Wireless Communication, Includes Rechargeable Battery and SolidSignal Cleaning Wipes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/34253320-eartec-ul4d-ultralite-hd-wireless-intercom-headset-system-4-person](https://www.desertcart.at/products/34253320-eartec-ul4d-ultralite-hd-wireless-intercom-headset-system-4-person) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-16*
