Wired Headphone with 30mm Drive Unit and 20 to 20,000Hz Frequency

Product Detailed Description

A reliable wired headset for office workers, call-center desks, and commuters who want clear sound without fiddling with batteries or pairing. The dual 3.5mm plugs connect straight to desktop computers, making it a practical giveaway for corporate training rooms and everyday workstation use.

Inside the earcups, 30mm drive units cover the full 20 to 20,000Hz range, while the built-in omnidirectional microphone handles voice calls and online meetings with a wide 40Hz to 16kHz response. Sensitivity of 105dB means comfortable listening levels from modest source power.

Promotional distributors can adapt this proven frame to their programs with cushion or headband branding and private-label packaging, options the headphone category routinely supports. Presented as a gift or bundled with computer speaker listings, it gives retailers a straightforward wired audio line alongside wireless models.

Stock is supplied in standard export packaging; inquire for current availability and customization details.
