“I never want to be without my Myna custom IEMs, so I’ve ordered a second pair as a spare.”
-Jonathan Andrews, Production Mixer

MYNA™ M7506 IEMs

MYNA™ M7506 custom-molded in-ear monitors (IEMs), designed for production sound professionals, are engineered to mimic the sound characteristics of the popular Sony® MDR-7506 headphones. Additional MYNA™ models are in development to mimic other popular industry-standard headphones.

An industry first, MYNA™ IEMs mimic specific headphone models so that, when changing back and forth from MYNA™ IEMs to the headphone model they mimic, the sound quality is virtually the same. MYNA™ IEMs provide the acoustic isolation and versatility of hand-crafted in-ear monitors while allowing the user to keep their point of reference.


Myna custom molded CM770  in-ear monitors mimic the sound of the Beyer DT770 Pro headphones. This allows users of DT770 headphones to also listen with Myna in-ear monitors while keeping the sound reference of the DT770. Users of Beyer DT770 headphones often choose them because of their warm, full-sounding, extended low frequency response and clear, high frequency transients. Audiophiles also often prefer the DT770s for these reasons.

Like other Myna models, the CM770 has five drivers in each ear, are very high-quality handcrafted earpieces, designed for professionals who work with headphones, and made in the USA.


MYNA™ IEMs are available in four styles, all of which sound identical and have polished black resin bodies.

Keep Your Reference

Before MYNA™, IEMs were primarily designed to meet the needs of stage musicians for live performances. Some models are made to emphasize specific instruments; bass players might prefer more low-end, guitar players usually prefer more midrange, and vocalists might want more “sizzle”, etc. But until now, no IEMs have been made to duplicate a specific headphone monitor.


Versatile Cables & Connectors

The MYNA™ IEM development team realizes that production sound professionals have unique cable and connector needs. For example, most IEMs terminate only to an 1/8-inch plug. However, location sound pros need to be able to go back and forth between devices with 1/4-inch and 1/8-inch stereo connectors. Therefore MYNA™ cables terminate to an 1/8-inch connector that includes a 1/4-inch screw-on adapter for added versatility. In addition, knowing that production sound mixers often need cables longer than the standard 4-foot length to reach their carts, a 2-foot breakaway extension is available.

Most IEM brands use molded-on connectors that need to be replaced if damaged. Knowing the hard life that production sound equipment experiences, MYNA™ has partnered with PlusSound to pair each IEM model with industry-leading rugged Exo and X Series cables with field-serviceable connectors available on the Medium and Robust weight cable options.

Hearing Protection & Acoustic Isolation

A very important reason for using custom molded IEMs for location sound is the extreme acoustic isolation. This means IEMs can not only give you better monitoring but can help protect your hearing. MYNA™ IEMs are custom molded to fit your ears, creating a perfect seal from outside noise. Because IEMs block outside noise, they allow you to monitor at lower levels than you might with regular headphones.


“In a noisy downtown production, my custom molded Mynas are the right tool for the job. They allow me to know exactly what the mics are recording in a compromised environment.”
-Steve Grider, Production Mixer

When using standard headphones in a very loud environment, it can be difficult to tell the difference between audio from the microphones and sound leaking through the headphones.

This makes it difficult to know what is actually being recorded. With MYNA™ custom molded IEMs, if you hear it, you are hearing it from the microphone. And it works the other way too. If you don’t hear the airplane overhead that everyone else is concerned about, you can let the director know with confidence that it’s not a problem.

IEMs are also very useful when working in windy conditions or on a moving vehicle. The wind blowing onto standard headphones can sound exactly like the dreaded sound of wind on the microphone. Custom molded IEMs don’t have wind noise, so if you hear wind, you know it’s being recorded.

Designed for Long-Term Wear

While it is common for stage musicians to wear their IEMs for two or three hours a day, film and video production sound crews typically wear their headphones or IEMs for 10 or more hours each day.

To accommodate location sound professionals, MYNA™ IEMs are crafted from the same type of hypoallergenic medical-grade resin as hearing aids to prevent skin irritation from long hours of constant use. Each set of MYNA™ IEMs is also hand polished for a smooth and precise fit to prevent “hot spots” from long periods of use.


“I’m very happy with my custom Myna’s custom fit and robust quality, and I’m very happy with the sound.”
-Kevin Santy, Boom Operator



Another reason production sound professionals are adding IEMs to their kits is that they often find themselves in settings that are problematic for regular headphones. Recording on location often means being in nature’s elements, requiring sun or rain hats that interfere with headphones. Construction hardhats are required for certain locations, and military operations might require helmets, which also make headphone use impractical. MYNA™ IEMs allow sound professionals to wear any protective headgear with ease.
