Smaller is bigger – flagship IEMs punching way above their weight

Picture the perfect transducer, something you could listen to anytime, anywhere and any how. In 2022, that's been starting to look more and more like an earphone.

At least, that's been the case that in-ear monitors (IEM) have been making since the turn of this decade. A case of smaller is bigger. More use cases, more convenience. Now, quantity of application is turning into quality of application.

Zeppelin & Co. took the opportunity at CanJam Singapore 2022 to deliver a seminar expounding on the leaps and bounds IEMs have come along in the last three years, following CanJam 2019.

It was posited: convenience is no longer the only selling-point of IEMs. Their level of fidelity and realism in 2022 means that they surface as candidates in use cases – where they weren't always the natural first choice.

Like at the desktop. Perhaps over a competing transducer that's bigger and arguably more associated with fidelity for critical listening. But progress begins with us trying to have this conversation.

Oliver Marino told Headfonia "the market has exploded". Following the interview the Vision Ears lead designer gave in 2018, the tide has been swinging in the direction of IEMs. Increasing levels of hyper-resolution. Soundstages that defy the physics of their small shells. Accurate phase response so micro and macro dynamics snap and portray music realistically.

While retaining the original pitch that made IEMs compelling in the first place: it's fidelity you can listen to anywhere, even on the go. But let's carry on, and add to the IEM case.

Infinite scaling. 

IEM development cannot just be viewed in a vacuum. Since the turn of the decade, amplifier and music player companies have been designing gear to elevate these miniature transducers to larger-than-life quality and scale.

Efforts that began with trying to drive AKG's K3003i to maximum levels in turn were diverted to Sony's IER-Z1R and now the 3ohm flagships of Empire Ears.

People have wondered to us whether Cayin Audio's C9 will really make a difference if they don't use headphones. We argue, something like C9 will improve more dramatically yet a flagship IEM with its complexities today. Overkill? Never.

IEMs have emerged in quantity and quality, and the amplifier and source market has risen in turn to match it. That's what turns a concept, into industry. With research and development hours, and dollars, pouring into it. And more yet to follow. The results, patently audible.

Because on paper, implemented correctly, 14 drivers should outperform one. Correct. As many heads put together should also build something much greater than one – manufacturing, research, business, community, consumers.

IEMs aren't small. They don't occupy our world. We occupy theirs. Next time you put one in, think about everything, everywhere all at once, that led up to the moment. Then exhale, breathe, and imagine where IEM development at this pace will lead us in the next 10 years.
