Sennheiser XSW-D Mini Jack Digital Wireless System

The XSW-D Mini Jack components add 2.4 GHz digital wireless to any device with a 3.5mm input or output, from an existing lavalier mic to a camera's headphone jack. The receiver clips onto a camera and outputs a 3.5mm mic-level signal; the transmitter clips to a belt or bag and accepts a 3.5mm source, so the pair extends the range of gear that was never built wireless.

aptX Live encoding keeps latency under 4 ms, tight enough for lip-synced camera audio, and the units pair automatically out of the box. A Li-Ion battery runs up to 5 hours per charge, and both the RX and TX are sold individually to mix and match with other XSW-D pieces already in a kit.
