Wired in-ear earbud headset CONCEPTRONIC BRENDAN04B — USB-C, 20–20000 Hz, 1.2 m cable, 14 g, black

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

Recommendations

For reliable operation, use the headset with devices that explicitly support USB-C audio output. Adjust device volume before extended listening to avoid sudden loud playback. Clean the earbud surfaces regularly according to the device manufacturer's guidance and store the cable without tight knots to preserve the connector and wiring.
