Sennheiser XSW-D Portable Lav Microphone Kit is a compact wireless lavalier solution designed for on-the-go creators and professionals, ideal for immediate use after its release.

This Sennheiser XSW-D Portable Lav Microphone Kit features a condenser lavalier microphone with a supercardioid pickup pattern, delivering focused voice capture and a sensitivity of 20 mV/Pa for clear speech reproduction across a frequency response of 50–18,000 Hz.

The kit includes a camera-mount receiver and a plug-in transmitter operating in the 2400–2483.5 MHz band with GFSK modulation, providing an RF power of 10 mW and a robust signal-to-noise ratio of 106 dB while keeping total harmonic distortion to just 0.1%.

Designed for practical connectivity, the system offers a 3.5 mm (1/8") input, supplied audio and USB Type-A to USB-C cables, and a built-in Li‑Ion battery that runs up to approximately 5 hours at 3.7 V. Both transmitter and receiver share compact dimensions (86 x 24 x 28 mm) and weigh 73 g each for balanced handling on camera rigs.

With a maximum sound pressure level of 130 dB and an operating temperature range from 0 to 55 °C, the kit handles loud sources and a variety of field conditions. The package also includes a microphone clip and a mounting kit to simplify setup on cameras or clothing.

Typical use cases include interviews, vlogging, broadcast work, corporate presentations, and event recording where discreet wireless audio and quick setup are essential. The portable design and camera-mount receiver make it especially suitable for solo creators and ENG-style shoots.

The key selling points are its reliable wireless link in the 2.4 GHz band, lightweight transmitter/receiver pair, clear condenser lavalier sound with supercardioid directionality, and convenient built-in battery and accessories that support fast deployment.
