Good device

Très bien pour la communication entre 2 personne sur un bateau

Honestly amazing. My dad has a 50 foot power trawler and when coming into the marina, we would have to shout to hear each other. If there was wind, we simply couldn't hear each other, especially with the thrusters. These are a game changer. Can talk to each other as if you're in a library. 10/10. 100% recommend

I owned a set of four older Eartec radios.. the kind with a big box that clips on your waste (or stand) and then separate headset. The units still work as well as they ever have (and we love that we can plug them in with A/C power for extended full-day gigs) -- but they had excessive hissing and noise which made them unpleasant to use. So we purchased these Eartec UltraLITE radios and -- LOVE THEM. We've used them a few times now and here's my experience: 1. Virtually zero hissing/noise -- in our event the last two days, there was literally *no* unwanted noise -- so little that I didn't think they were on except when my crew was talking! 2. IMPRESSIVE Range -- With the master and my crew at the back of a full-size theatre (100' from front to back), I exited the theatre and went another 30 feet back into another black box theatre -- through concrete walls.. and we maintained crystal clear conversation -- WOW 3. QUICK Charging Batteries -- I think they must used Alien Tech to build this stuff.. the batteries presumably last about 6 hours (we haven't tested it that long but HAVE tested 4 hours without an issue), and charge fully in about *15 minutes* (or so it seemed) -- Incredible!! 4. Flip-up-to-Mute -- Works as promised. Flip up the mic boom and no-one can hear your conversation.. simple! 5. Comfortable headset --- but it is a little snug (we wear a small hat underneath). That said, I feel it's a good balance, tight enough to stay on as we move around, but not soo tight it is painful. Very much appreciate that the mic boom flips both directions so the unit can be worn on either ear. And lightweight -- LOVE not having that brick on our waste and wires! 6. Published Frequency Specs -- I love that they operate outside any range that might interfere with theatre mics.. a great relief! TWO Improvements I'd like to see -- 1. Ability to disable the blue light (yes.. I know a wad of GAFF tape can cover that) 2. An "OFF" button on all units which actually turns it off; the manual says that if the battery is left in it will continue to drain, so we habitually keep the batteries out before each gig. It would be way more convenient to be able to keep the batteries in. (perhaps I misunderstood and it drains so little that we can, in fact, keep them in the day before the gig??) 3. The noise cancellation does not seem quite as good as our older units -- in a loud theatre with music playing, the booms do pick up the ambient sound somewhat, so we hear it come on and off through the system.. I think there is room for improvement here HIGHLY recommend these units :-) :-)

For the price I paid i was not expecting the headset to be loose after couple of month. Poor quality

Excellent product Does exactly what’s required for easy and clear communication
