In a nutshell
Lighter than Sennheiser HMD 25-1, Sennheiser HMD 410-6 is an open headset with 600 ohms impedance for each phone. It can provide sound pressure level of 100 dB, with total harmonic distortion lower than 1%. Yet, its response curve is larger with high frequencies and goes from 20 Hz to 18 kHz.
The supercardioid dynamic microphone is perfectly suitable for an intercom system, with 1 mV/Pa sensitivity and reduced response curve from 50 Hz to 12 kHz, with low proximity effect.
So the proper use of this headset is more in an intercom system than for genuine sound recording.
