For modularity, the headset feature the company's EM-X in-earphones, which can be switched with earphones of the user's choice. The flexibility also extends the serviceability and lifetime of the product. The headset has a boom with a moving-coil dynamic element with a cardioid pattern and a frequency response of 200 to 10 kHz. The earphones feature a single-driver ported design and come with three sizes of eartips, a windscreen with an o-ring, and a custom storage case.
