I like to start my reviews with a little story. Since I’m first and foremost a creative writer, finding the story helps me get started.

Well, there’s no story here. I found Periodic Audio by looking through the forums for my next article. I contacted them, and they sent out their top model, the Be (Beryllium).

 

Why Be? It looks like Periodic Audio uses the Periodic Table as a naming scheme. Be is the official designation for the element known as Beryllium, which makes up the diaphragm of the dynamic driver. They manufacture all this in-house, and sweet god are the results impressive.

Taken from their website:

Frequency Response
12 Hz to 45 kHz
Impedance
32 Ohms nominal
Sensitivity
100 dB SPL at 1mW in ear
Power Handling
200 mW continuous
Peak SPL
123 dB
THD
Less that 1% THD at 1mW

The shell is a light and sturdy polycarbonate. The cable is thin and flexible, with very little memory. Cable-down is a bit awkward, but if I wear it looped over the ear, I’ve had good experience. Just add a few twists, and it serves as a chin cinch to keep the wire from flopping over your ear. In this fashion, the Be wears fairly transparent and transmits practically no microphonics.

Periodic is a weird company. They don’t care whether you reverse the Left and Right signals. You know this to be true, as there is no L and R markings anywhere. Not on the IEM, nor the cable. However, the nozzle seems to be at a subtle angle. Very subtle. I think. It’s terribly hard to tell. And you can try… try… and figure out which goes in which ear based on that. But of course, this goes out the window if you wear the IEM upside-down, which is how I do it for the over-the-ear style.

Other than that, and my eternal wish for replaceable cables, I have no complaint about the build. This is a solid product.

Pinky is an artsy twat. Illustration, graphic design, writing. Yet music escapes him, and always has. He builds his own cables, and likes to explore the craftsmanship of others. He's a stabby one, also. At the first hint of annoyance, out comes the blade. I say he's compensating for something... in a big bad way. If we all try really hard as a collective, maybe we can have him put down.

    Pinky, I’ve enjoyed your writing over a number of reviews lately. Keep up the good work and your wonderful handling of the English language (which I must say is somewhat lacking on certain other audio-oriented sites). But I must take exception with you about the IT01 — it is nowhere near as good as the Be. The BE’s low bass (sub-bass) is stronger and better defined (through both my Fiio X7mkii and Opus #2). The IT01 has no low bass to speak of; even using EQ it won’t come out and remains simply a dull thudding presence at the bottom. It’s midrange is also too prominent and requires EQ-ing, whereas the Be is simply better balanced overall. I have to admit to being pretty puzzled by the positive response to the IT01. But not to the Be.
