Based on the closed-back, dynamic HD 280 headphones, the HMD 280 - 13 headset has been especially designed for communications in high-noise environments. Its dynamic, super-cardioid microphone has been optimised for close talking distances.

• HMD 280-13 is the same as the HMD 280 pro, but with 300 Ω headphone impedance
• Noise-compensated microphone with extremely low handling noise
• Microphone can be worn on either left or right-hand side
• Easily replaceable, single-sided coiled cable
• Very good attenuation of background noise
• Space-saving design with rotating earpieces
• Replaceable parts for long life
• Lightweight design
• 300 Ω (ohm) headphone impedance
• Delivery includes: 1 HMD 280 -13, 1 foam windshield
