Tabletop conference mirophone with TRRS 3.5mm plug. Replaces MIC

The Williams AV MIC 449 is a compact tabletop conference microphone built around an electret element. Its black, low-profile enclosure measures 60 mm in diameter and 16 mm in height, while a 39-inch (99 cm) cord terminates in a 3.5 mm TRRS plug. An omnidirectional polar pattern, 1500 Ω output impedance, and specified 1.0–10 VDC bias power requirement define the electrical and pickup characteristics buyers should confirm before integration.

Ideal Use Cases

The MIC 449 is intended for tabletop conference applications. Its omnidirectional polar pattern is suitable for arrangements in which voices may come from multiple directions around the microphone rather than from a single fixed position. The 60 mm diameter gives it a compact tabletop footprint, and its 16 mm height keeps the enclosure close to the work surface. It is appropriate for systems that accept a 3.5 mm TRRS connection and provide the specified bias power.

Why Choose This Model

This model combines a compact conference-oriented form factor with clearly defined connection and electrical requirements. The attached 39-inch (99 cm) cord provides a known cable length for planning placement relative to the connected device. Its black finish offers a neutral appearance for conference tables and meeting spaces. Buyers can also evaluate compatibility using the published 1500 Ω output impedance, 1.0–10 VDC bias requirement, and 40 dB ± 3 dB sensitivity specification.

Installation and Integration

Position the microphone on the tabletop where its omnidirectional pickup pattern can serve the intended seating arrangement. Route the attached cord toward the receiving device without exceeding the available 39-inch length, then connect the 3.5 mm TRRS plug to a compatible input. Before installation, confirm that the receiving equipment uses the required TRRS connection and supplies bias power within the specified 1.0–10 VDC range. Connector shape alone does not establish electrical compatibility, so the input requirements of the connected equipment should be checked. The compact 60 mm by 16 mm enclosure should also be considered when planning surface placement and cable routing.

Performance Highlights

The MIC 449 uses an electret microphone type and requires external bias power within its stated operating range. Its omnidirectional polar pattern is the central pickup characteristic, allowing the microphone to receive sound arriving from around its position. Published electrical specifications include an output impedance of 1500 Ω and sensitivity of 40 dB ± 3 dB. These figures provide concrete reference points when matching the microphone to conference equipment. Frequency response, maximum sound pressure level, and signal-to-noise specifications are not provided in the available product data and should not be assumed.

What Makes It Different

The defining combination is its low-profile circular tabletop body, omnidirectional electret design, and integrated TRRS connection. At only 16 mm high, the microphone has a notably shallow enclosure, while the 60 mm diameter establishes a stable, compact footprint. The fixed 39-inch cord eliminates uncertainty about the supplied cable length. Product resources also include a microphone image, a jack diagram, and a manufacturer specification-sheet PDF, giving buyers additional references for reviewing the physical product and connection before purchase.

Final Assessment

The Williams AV MIC 449 is a purpose-specific tabletop conference microphone with a concise, well-documented set of core specifications. It is best selected when the intended system supports a 3.5 mm TRRS plug, can provide 1.0–10 VDC bias power, and is compatible with a 1500 Ω microphone output. Its omnidirectional pickup, compact black enclosure, and 39-inch cord make its placement requirements easy to assess. The product is covered by a 90-day warranty.
