## Long description

CONCEPTRONIC BRENDAN04B is a wired in-ear earbud headset with a USB-C connector designed for voice calls, conferencing and audio playback on devices with USB-C ports. The intraaural design positions the earbuds inside the ear canal for stable fit and direct sound delivery. With a frequency response of 20–20,000 Hz and a 1.2 m cable, the headset is lightweight (14 g) and suitable for daily mobile use where a wired USB-C connection is required.
Advantages
The headset combines a USB-C digital connection with an intraaural ear coupling to provide clear audio across the audible frequency range. Its 1.2 m cable provides sufficient reach for most handheld and desktop scenarios while remaining tangle-manageable. At 14 g, the design is light for extended wear. The built-in in-line microphone and remote enable hands-free calling and basic media control without interacting directly with the connected device.
Suitable for
 Voice calls and teleconferencing on USB-C phones and tablets
 Listening to music and podcasts on USB-C devices
 Portable use with laptops and devices that support USB-C audio
 Everyday commuting and on-the-go audio where a wired connection is preferred

How to use
