BBS U-798D Wireless Handheld Microphone System

Tested
Grade A
Availability: In stock

A complete multi-transmitter wireless system with 1U rack receivers, already built around KTV and conference use; ask for a full channel scan and a battery test on every handheld.

Best for: KTV rooms running several handhelds in rotation, where one receiver rack has to serve multiple singers through the night without a cable swap.

Watch out for: Used wireless systems are often split up: confirm the transmitters and receivers are on the same frequency band and that no channel drifts or drops out during a ten-minute walk test.

Pattern: Cardioid
Type: Wireless handheld transmitter & receiver
Frequency range: 50 Hz – 18 kHz

beyerdynamic Opus 29 S Dynamic Microphone

Tested
Grade A
Availability: In stock

A cardioid dynamic handheld that keeps its tone when singers cup the grille, and this unit still has its original clip, case and cable.

Best for: Wired vocal positions and small KTV rooms where a cable is acceptable and no frequency coordination is needed.

Watch out for: Check the XLR connector for play and the grille for dents from dropped stands — a loose connector is the usual fault on handhelds that have lived in a club.

Pattern: Cardioid
Connector: XLR
Frequency range: 40 Hz – 18 kHz

Crown CM-310A Dynamic Microphone

Tested
Grade A
Availability: In stock

Differoid dynamic capsule with strong rejection of stage wash, which helps in small rooms with loud monitors and close walls.

Best for: Speech, MC and backing-vocal positions in tight rooms where bleed from the monitor wedge is the main problem.

Watch out for: The Differoid body is heavier than a standard handheld and the windscreen is model-specific — confirm the windscreen and clip come with the mic.

Pattern: Cardioid
Connector: XLR
Frequency range: 50 Hz – 15 kHz

How we rank

Each unit in this list is photographed as it stands and bench-tested before it goes on the page. The order is set by our inventory team on parts availability, service history and how the model holds up in rental use — never by sponsorship or paid placement. We do not publish sales totals we cannot verify.

What to check before you buy

Ask for photos and a video of the exact serial number you will receive, not a stock picture.
Confirm amplifier, DSP presets and rigging hardware are included — they are the most expensive parts to source later.
Check driver surrounds for foam rot and ask whether any driver has been re-coned.
Match voltage and mains plug to your country before shipping; 110 V and 230 V versions are not interchangeable.
Budget for freight, duty and a service check on arrival — used gear is priced FOB, not delivered.

The scenario this shortlist is built for

KTV room sound system for private karaoke suites Vocal-first setups: ceiling speakers, one amp per room, wireless mics.

Buyer questions

Are the units in this ranking actually tested?

Yes. Each unit is powered up, run through its inputs and outputs and checked for noise, fan condition and channel balance in our warehouse. The test result is recorded against the serial number; ask us for it before you pay.

What condition grade do these units carry?

Grades are shown per unit: A means 90% or better cosmetic condition with no functional faults, B means visible wear but full function. The grade in the table is the grade of the actual cabinet you will receive.

Can you supply several units of the same model?

Often yes. Quantities change weekly because stock comes from trade-ins and rental fleet rotation. Tell us the model and quantity and we will confirm what is on the floor today.

How is used gear shipped and what if something arrives faulty?

We ship FOB port of loading by sea or air, crated or palletised for export. Every lot carries a 90-day test warranty: if a fault covered by the test report appears, we ship the replacement part or arrange a repair credit.
