Bwexxt BZ091 3.5mm condenser microphone

The Bwexxt BZ091 is a compact condenser microphone with a 3.5mm 4-pole jack that also accepts 3-pole connections. It is designed for users who need a simple, portable audio capture tool for smartphones, laptops and computers. The microphone ships in new condition and features a black finish.

Plug-and-play 4-pole 3.5mm aux connection

The 4-pole mini jack plugs directly into a combined headset port on a phone, laptop or recorder without requiring drivers or external power. Its lightweight build keeps the setup minimal for mobile recording, karaoke apps or video calls. The cable frees up USB ports and avoids the need for an audio interface.

-38 dB sensitivity condenser capsule under

The built-in condenser capsule operates at a sensitivity of -38 decibels, delivering clear, detailed sound during extended voice-memo sessions or long karaoke recordings. Because it draws power from the host device's microphone bias, performance remains consistent without battery management. Users who require professional studio noise floors or directional pickup patterns will find this microphone does not meet those needs.

Questions about this item

How much handling noise does the -38 dB condenser capsule pick up during long karaoke sessions?

The -38 dB sensitivity captures voice clearly but also picks up nearby room sounds, so keep the mic steady and away from rustling clothes during extended use.

Does the 3.5 mm plug get warm or draw noticeable power after hours of recording?

It is a passive condenser that draws only mic bias from the host port, so the plug stays cool and power draw is negligible even after all-day sessions.

Which devices must already have a combined 3.5 mm TRRS jack for this BZ091 to work?

Smartphones, laptops, tablets or recorders with a single 4-pole 3.5 mm headset socket — separate mic and headphone jacks need an adapter not included.
