Mode of Operation
Condenser (Small Diaphragm)

Mode of Operation

Condenser (Small Diaphragm)
Very accurate and fast in response. Suitable for instruments with detail and high frequencies (acoustic guitar, piano, overheads).
Directivity
Unidirectional (Cardioid)

Directivity

Unidirectional (Cardioid)

Cardioid: Captures sound primarily from the front, reducing sounds from the sides and rear. Ideal for vocals, podcasting, and live recordings.
Frequency
70 - 16000 Hz

Frequency

Indicates the frequency range that a microphone can capture and is expressed in Hertz (Hz). The more balanced the range, the more natural and clear the sound.

Usage examples:

  • 100 – 10,000 Hz to 200 – 12,000 Hz: Emphasis on speech intelligibility, with limited low and very high frequencies.
  • 50 – 14,000 Hz to 80 – 16,000 Hz: Balance of volume and clarity. Ideal for live performances and dynamic microphones.
  • 40 – 15,000 Hz to 50 – 18,000 Hz: Rich, natural vocal sound. Suitable for podcasts, radio, and streaming.
  • 20 – 18,000 Hz to 20 – 20,000 Hz: Full spectrum with high detail and "air". Ideal for studio recording.
  • Below 20 Hz & above 20,000 Hz: Extended technical range for specialized studio applications.
Impendance
150 ohm

Impendance

Indicates how "easily" the microphone transmits its signal to the equipment (mixer, sound card, amplifier). It is expressed in Ohms (Ω).

  • Low impedance (≤ 600 Ω): Stable signal, less noise, ideal for professional equipment and long cable runs.
  • Medium impedance (600 – 1,000 Ω): Good balance, common in live and general use.
  • High impedance (> 1,000 Ω): More sensitive to loss and noise, usually found in older or specialized equipment.
Max SPL
136 dB

Max SPL

Max SPL (Maximum Sound Pressure Level) is the maximum sound pressure level (in dB) that a microphone can withstand before it starts to distort the sound.

  • High Max SPL (e.g., 140-160dB): Ideal for recording loud sources such as drums, amplified guitar, or live concerts.
  • Lower Max SPL (e.g., 120dB): Suitable for vocals and softer recordings.

The higher the Max SPL, the louder the sounds it can capture without distortion.
Signal-to-Noise Ratio (SNR)
38 dB

Signal-to-Noise Ratio (SNR)

Indicates the difference between the useful signal and the microphone's noise. The higher the value in dB, the clearer the sound. A microphone with a low SNR may sound “noisy,” especially in quiet environments or when recording low-volume sounds. On the other hand, a high SNR means that noise is minimal compared to the sound you want to capture, offering a more professional, clear, and detailed result—ideal for studio, vocals, or high-quality recording.

  • 35 – 60 dB (Low SNR): Noticeable noise is present. Suitable for casual use or loud sources.
  • 60 – 90 dB (Medium SNR): Good signal-to-noise balance. Suitable for live performances and general use.
  • 90 – 110 dB (High SNR): Very clear signal with minimal noise. Ideal for studio, vocals, and high-quality recording.

    Disappointed, both on Windows (with Asio drivers - since it doesn't have its own) and on Mac, I constantly have clicking sounds and my sound is never clear.

    Crystal clear sound and good build quality, except for the base, which is made of plastic. I mainly use it for calls from my computer. The sound quality, according to the callers, is impressive and at the same time it isolates sounds from the environment (cars, motorcycles, other people in the house, etc.) and they are not transferred to the call.

    Overall, it is a very good choice for a limited budget and fully meets the requirements of everyday use.
