Review: Works great for our church team! - We use the Eartec UL5S for our church services and livestream production. It’s super easy to set up, and the sound is clear with no delays. The team loves being able to talk hands-free during service without any wires. Battery life is great too. Definitely worth it!
Review: Awesome set! - Bought this for our middle school auditorium, as our ancient wired headsets finally punked out. These are awesome! The signal and volume were excellent, the battery charging was easy and quick, the batteries lasted long, and having the freedom to move about the space was so great for the kids. We are planning to purchase a HUB and add more units for more of the crew to be connected.

## Questions & Answers

**Q: Once batteries are charged do i need to unplug charger or can i leave batteries in the charger (i don’t want to damage the batteries)**
A: I myself, remove the batteries and charge them after each performance.  After they  have completed charged, I remove them from the Charger and store them separately from the headsets.  The batteries are lithium ion and should never be overcharged as they could explode.

**Q: This comes with a master and 3 remotes.  can spare remote be used as master if master is damaged?**
A: The battery went dead on the master unit during a show and none of the headsets would work without it.  Fortunately, I had extra batteries for all the units and replaced them.

**Q: Does this system come with the case that's pictured?**
A: Yes a small bag is included with the package

**Q: If I buy the 4 singles, they will be able to speak and hear all together at the same time? do I need a base?**
A: You need the base master unit.  You should buy a set of 4 so they talk to each other.  I bought a single and could not get it to talk to the other units.

### ⭐⭐⭐⭐⭐ Awesome set!
*by P***L on April 19, 2019*

### ⭐⭐⭐⭐⭐ Perfect for small/medium church application.
*by J***M on December 30, 2019*

Got this for the media team at my church of 300~400. Only ever need the five that I can tell. Work like professional headsets, very clear wireless audio through multiple walls and in a multistory building (through thick concrete and steel floors). Only ever use them in relative close proximity though, and just for a couple of hours so I'm not pushing them to the limit in any aspect. Only trade-off for the lower price range is a cheapish plasticy feel, and the battery door is a little tough to open and close.
