The USA version UltraLITE Single-Ear Master Headset with Rechargeable Lithium Battery from Eartec is a self-contained, replacement full-duplex wireless intercom headset. It can be used to provide simultaneous talk and two-way voice communication for users that need to work with their hands, yet also require one ear free to listen to what is going on around them.

The system eliminates belt-worn radios because all electronics are built into the ear cups. The fully adjustable noise cancelling microphone ensures effective voice communication.

Related Questions and Answers

Q: 1. if i buy two kits of 4 singles, can i sync them to work like 8?

A: One of the headsets in any Ultralite communications system is pre-programmed as the master, so you would not be able to simply take two sets of four and make an eight- person system out of them. Also, a system of more than 5 stations requires an Eartec HUB Mini Duplex Transceiver Base for 1 Plug-In & up to 8 Wireless UltraLITE Headsets (USA), BH #EAHUB. This is an example of an 8-person system: The Eartec HUB8S UltraLITE 8-Person HUB Intercom System (USA), BH #EAHUB8S. Nine is the limit of stations feasible with the Eartec Ultralite wireless systems.

Q: 2. what mean USA version?...its usable only on USA?

A: The Multi-Port Charging Base included with this system ships with a power supply that supports 120VAC only. A voltage converter for use outside of the US would be required.

Q: 3. what are the differences between Black and Gray ones? Gray ones seem to connect 5 head sets. Can black one connect with 5 without hub?

A: All current Ultrlite headphones are the black colored HD version. 5-person systems can still operate without the additon of a hub. A hub wil allow for up to a 9-person system.

Q: 4. Would these work for use on an airboat, considering the noise both in the ears as well as in the microphone (picking up the propeller sound). Thank you

A: The Eartec headsets are designed for use in environments with high levels of noise so they should work very well on an airboat.

Q: 5. if i buy the 5 person duplex does that already come with hub or do i have to buy that separately?

A: This system does not come with a hub, but it does come with one master headset. It will work as is, out of the box without the additional hub.

Q: 6. Does this set work in Europe? And if not can you point me to the proper one? Thanks.

A: The Eartec UL5S 5-Person Full-Duplex Wireless Intercom with 5 UltraLITE Single-Ear Headsets implements the "USA" versions of the Eartec UltreLITE components and is not recommended for use in Europe due to frequency and power compatibility. A similar version specified for use in Europe is the Eartec HUB532EU UltraLITE 5-Person HUB Intercom System (EU) (BH #EAHUB532EU): https://bhpho.to/3BZq71u

Q: 7. I want to buy 6 of this for a Tv series ! But the idea is buy 4 now and 2 more after 1 month ( week before we gonna start to shoot) If I buy 4 single for use in USA I can buy 2 more later and it’s would be work great ? Please help me

A: The master headset included with the Eartec UltraLITE 4-Person Full-Duplex Wireless Intercom can be used with up to 5 remote headsets. In order to accommodate 6 headsets, you will need to purchase the Eartec HUB Mini Duplex Transceiver Base for 1 Plug-In & up to 8 Wireless UltraLITE Headsets (B&H # EAHUB) which would replace the master headset. The HUB can be used with up to 8 wireless remote headsets and 1 wired headset that will connect directly to the HUB to accommodate a total of 9 users. The master headset and HUB both have the same electronics built-in and cannot be used together and the HUB only works with wireless remote headsets and the 1 wired headset. You may want to consider purchasing the Eartec HUB6S UltraLITE 6-Person HUB Intercom System (B&H # EAHUB6S) from the start. The HUB can be powered with a battery and worn like a beltpack. 2 HUBs can be linked to accommodate up to 16 wireless remote headsets and 1 wired headset.

Q: 8. Just to clarify, so I have purchased these already, would I be able add more to this system and if so how do I sync them? I would like to have 6-7 working together. Thanks

A: First, please make sure that your current system has "HD" written on the earset. If this is not the case, then you would need a whole new system. If it does, then in order for you to use 6-7 headsets at one time, you would need to purchase a HUB and an additional 3-4 remote headsets. Please keep in mind that the HUB will be replacing your current Master headset. Here are the sku's B&H # EAHUB, and BH #EAULDR.

Q: 9. can we add more user ? and this only can use for USA ?

A: Thank you for your question. This system will max out at 9 users. We only have this system configuration available for USA usage only at the moment.

Q: 10. Suppose two systems are in use in the same location, i.e. a sports events where both teams have the same system. Are the satellite headsets paired with Master?

A: Each group of headsets are made to work within that system. If you have two separate systems and you want to combine them to use them in the same group, you can contact Eartec Tech Support and they will be able to help you get both systems into the same group.
