The package includes one main single-ear headset, two remote single-ear headsets, three rechargeable lithium batteries, a 10-bay multi-port charger and a softside carry case, which together make setup and daily transport straightforward. The single biggest reason to buy is the combination of full duplex operation and strong noise-cancelling voice clarity, which keeps conversations natural and intelligible even in noisy environments.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eComplete 3-person kit:\u003c\/strong\u003e Comes with 1 ULSM main headset and 2 ULSR remotes plus batteries and a dedicated 10-bay charger for ready-to-go use by a small team.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eHands-free full duplex:\u003c\/strong\u003e Operates on 1.9 GHz for simultaneous two-way conversation among users without push-to-talk delays.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eExpandable system:\u003c\/strong\u003e Factory system supports three users out of the box but can be expanded to up to five users when needed for larger crews.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eGood wireless range:\u003c\/strong\u003e Up to 1,000 ft line-of-sight range keeps crew members connected across stages, sets, or job sites within that span.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eNoise-cancelling mic:\u003c\/strong\u003e The microphone filters ambient noise and mutes when pivoted up, maintaining clear communication in loud environments.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003ePortable charging and case:\u003c\/strong\u003e The included multi-port charger and softside carrying case simplify battery management and transport between locations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe UL3S is well suited to video and stage production crews, small event teams, drone operators, boat operators and light construction or UTV teams who need dependable, real-time voice coordination across short to medium distances.
