Product information

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

Frequency response: 20–20,000 Hz
Cable length: 1.2 m

How to use

Connect the USB-C plug to a compatible device that supports USB-C audio. Insert the intraaural earbuds gently into the ear canal until comfortable and stable. Use the in-line remote to answer or end calls and to control basic playback and volume functions. For calls, keep the in-line microphone positioned near the mouth to improve speech pick-up. Disconnect the headset by pulling the connector straight out from the device when finished.

Usage 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.
