## Long description

Wired stereo headphones with built-in microphone provide a frequency response of 30–16000 Hz for the headphones and 100–16000 Hz for the microphone. The headphones have an impedance of 32 ohms and a sensitivity of 91 dB SPL/1 mW. The microphone sensitivity is specified as -56 dB ±3 dB (per 1 V/1 kHz) or -36 dB ±3 dB (V/Pa). Total harmonic distortion for the headphones is 1.0%. The cable length is 8 ft (approximately 2.4 m).
Advantages
These wired stereo headphones with microphone combine standard impedance and sensitivity values suitable for general consumer devices. The separate frequency ranges for audio playback and microphone capture allow clear reproduction of music and reliable voice pick-up. A low distortion level supports faithful sound output, and the 8 ft cable gives extended reach without requiring additional accessories.

Рекомендации
Для наилучшего качества звука и микрофона используйте устройство с подходящим выходным уровнем и убедитесь, что разъемы чистые и надежно подключены. Избегайте натяжения кабеля и резких перегибов. Если требуется меньшее расстояние до источника звука или компактность, используйте устройство с более коротким кабелем или переходник.
