Lighting Director Matt Jones on Ed Sheeran ÷ Tour wears CM-i3 with his custom in-ear monitors

World’s First Switchable In-Ear Headsets

for Intercom and Camera

CM-i3 Intercom Headset detached earphone

U.S. Pat: 9,271,065

Our patented in-ear audio headsets weigh between 1 - 2 ounces—making them too cool to pass up if you’re getting weighed down by heavy, bulky head clamps. The modular in-earphones allow you to customize the earphones to your liking, and do a better job of blocking out noise while boosting the audio.

CM-i5

Intercom Headset

CM-i5 In-Ear Headset, Audio Headset, Product Infobox

with Condenser Microphone
(requires bias* voltage)


CM-i3

Intercom Headset

CM-i3 In-Ear Headset

with Dynamic Microphone
(does not require bias* voltage)


What's the difference between the CM-i3 and CM-i5?

The key difference between the two headsets is the type of microphone element.

The CM-i5 has a CONDENSER microphone which is smaller and more lightweight but it requires bias* voltage.

The CM-i3 has a DYNAMIC microphone which does not require bias* voltage. Therefore it can be used with nearly any type of camera or comms systems.

Many newer comms systems today are workable with both dynamic and condenser microphones; verify that your belt pack supplies bias* voltage, if not, then the CM-i3 is your most versatile option.

*Direct current ( DC ), or DC voltage needed to charge the Electret Condenser microphone element. Many professional communication belt packs and devices provide sufficient voltage to charge the Electret Condenser microphone element.

The Best Headset Choice

Four Key Benefits of In-Ear Headsets

Protect Your Hearing

Protect Your Head

Practically tailor-made to wear under helmets, hard hats and hazmat suits!

Protect Your Health

Protect Your Well-Being

Are These Right for You?

The CM-i headsets are designed using our pro performance EM-X in-earphones. The one-of-a kind design brilliantly captures what traditional headsets have been lacking. For anyone who must work in loud environments, wear a helmet or hard hat, have health concerns about sharing headsets or bulky headsets that weigh too much, this solution will give them relief from all these problems. The headset’s low profile binaural in-earphone feature is a simple yet inventive method to block out noise and boost audio clarity—solving many age-old dilemmas experienced by headset wearers.

We let the audio precision of our miniature microphones and headsets speak for itself. But if you’re not sure which audio headset is right for you, contact us and we’ll be sure to give you the straight talk.
