Product information

Description

The Deltaco HL-21 Wired Binaural Headset with Boom Microphone is a reliable communication tool designed specifically for office environments and call centers. Featuring a comfortable on-ear supra-aural design and a secure head-band style, this black stereo headset provides clear audio transmission for daily professional tasks.

Advantages

This headset delivers balanced stereo sound across a frequency range from 20 to 20000 Hz, ensuring that voices and audio cues are heard clearly during calls. The integrated boom microphone captures speech accurately, while the flexible microphone arm can be easily adjusted or moved out of the way when not in use. Weighing only 70 grams and featuring a lightweight construction, it minimizes user fatigue during extended listening and speaking sessions. The 2-meter wired cable offers sufficient length for comfortable movement at a desk without restricting posture.

Suitable for

  • Office communication and telephone calls
  • Call center daily operations
  • Customer service tasks
  • Professional remote work and online meetings

This headset may not be suitable for users who require active noise cancellation technologies, wireless mobility, or deep bass reproduction for high-fidelity music listening and gaming entertainment.

Key specifications

  • Binaural stereo headset design
  • Supraaural on-ear fit with head-band style
  • Wired connectivity with a 2-meter cable
  • Boom microphone type
  • Headphone frequency range of 20 to 20000 Hz
  • Impedance of 32 ohms
  • Microphone impedance of 2200 ohms
  • Product colour: Black
  • Weight: 70 g

To use the Deltaco HL-21 headset, simply connect the wired cable to a compatible audio port on your computer, desk phone, or other communication device. Adjust the head-band for a secure and comfortable fit over your ears. Position the boom microphone close to your mouth for optimal voice pickup, and adjust the flexible arm as needed. No additional software installation is required for basic plug-and-play operation.

What to consider before purchase

  • Verify compatibility with your computer, telephone, or audio equipment connection ports
  • Consider whether an on-ear supra-aural fit suits your personal comfort preferences for long-term wear
  • Determine if a wired connection meets your mobility requirements in the workspace

For optimal longevity and performance, store the headset in a clean and dry place when not in use, avoid wrapping the 2-meter cable too tightly around the headband, and clean the ear cushions regularly with a soft, dry cloth.
