They are still going strong 3 years later and they really help keep our Audio Visual team on the same page. We have had ZERO problems and we highly recommend them. We've even used them for small projects, such as when someone need to go into the attic or into another room to run wire and make adjustments to equipment and needs to stay in contact with the team. It's great to have hands-free communication! ### ⭐⭐⭐⭐⭐ Good value for money *by A***N on October 1, 2020* We purchased these to see if they will help us minimize the number of people we have in a small space when working. We have only tested them so far, but for the price, especially, the sound quality and range are impressive and better than anticipated. They do appear to be cheaply made, which is expected because they are considerably less expensive than other industrial versions. This was a great way for us, as a nonprofit, to see if they will be practical for our needs and if they break, we will know whether it will be worth it to invest in the higher quality versions. Based on initial testing, I would recommend these as good value for money as long as you aren't expecting to get high quality craftsmanship! ## Frequently Bought Together - Eartec UL422 Ultralite-HD 4-Person Full Duplex Wireless Intercom Headset Communication System, Single and 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 Multi-Port Charging Base with Adapter for 8x LX600LI Rechargeable Li-ion Batteries --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/41116389-eartec-ul422-ultralite-hd-4-person-full-duplex-wireless-intercom](https://www.desertcart.pl/products/41116389-eartec-ul422-ultralite-hd-4-person-full-duplex-wireless-intercom) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-06*
