Technical Overview

Speaking technically, let's start by looking at some specifications.

Headphone :-

Frequency response: 18 - 28.000 Hz

Impedance: 40 Ohm

SPL@1kHz, 1V RMS: 99 - 104 dB

Cable length: 1,0 m + 1,8 m = 2,8 m / 9,2 ft.

Jack: 3.5 mm (6.3 mm converter included)

Microphone :-

Frequency response: 80 - 15.000 Hz

Impedance: 2K Ohm

Pick-up pattern: Uni-directional

Sensitivity (1V/P@1 kHz) -38 dB

On closer examination we can see that the Siberia Red has been provided with a frequency response figure of 18Hz-28,000Hz which is very good indeed, meaning in short that these headphones should pack some acoustic punch.

Sound pressure levels generated are given at a healthy 99-104db at 1 KHz which will be ample for generating more than enough gain to satisfy most users I would say.

Now, with the microphone side of things frequency response is given at 80Hz-15,000Hz which is plenty for a microphone intended for the uses that this one is.

The microphone pick-up pattern which is the way in which the diaphragm picks up sound is given as uni-directional, which means that it picks up sound from one direction only, as opposed for example to an omni-directional microphone which picks up sound from 360 degrees all around.

From a technical standpoint there is not a great deal more to discuss here and from the looks of the figures given and the overall design and feel of the product, things look good so far.
