The Science

Isolation is basically the key thing in sound, especially in lower frequencies. So, if you don't have isolation, you lose that. You don't get to enjoy all the lower-end of the spectrum.

So, what we did was, we took an average of people's ear impressions. This was possible thanks to our sister company, My Ears, who've been taking impressions for a very long time. We used those statistics and data to find one standard deviation – which is roughly 67% of the population – and have our product's size and shape adhere to that.

We especially focused on the outer pinna; the part where the IEM actually goes into the ear and sits on the lobe. We wanted it sealed as much as possible. The data (demographic) that we had were mostly Western with a little bit of Asia as well. So, we designed the shell according to that. The whole idea behind it is if we were able to seal the pinna as much as possible, we would be able to achieve incremental isolation of 10dB, and that's a lot.

Stealth Damping allows us to give you crispier bass. How does that happen? On the faceplate of the universal, you'll see something that looks like a turbine with a brass tip. Now, really, it's only the weight of that thing that's important; the turbine is just for design.

What it does is this: Think of a bass signal on an oscilloscope; let's say the drummer hits the bass drum. What you'll see is a spike, then you'll have a trail; a decay trail. Now, assume that decay doesn't decay as quickly as you want. What happens is that trail will build, and it'll accumulate into what we call boominess. Because of that, you begin to lose all the other frequencies; the boominess masks them and takes over.

So, by adding a weight - that we've specifically measured (with a bit of tolerance) - to the IEM, the weight is allowed to absorb only the low-frequency sounds. It's mechanical in nature. This allows the bass response to decay very quickly. When that happens, you hear a more crisp, clear bass, which also allows you to push it even further without diluting the other frequencies at the same time.
