Crystal Clear Wireless Audio. The Sennheiser EW-D SKM-S Digital Wireless Handheld Transmitter can be used from up to 328 feet away, but that doesn’t stop it from delivering high-quality audio perfect for stage musicians, singers, and speakers. Its 134 dB dynamic range eliminates the need to adjust input volume and prevents distortion, and when paired with the EW-D receiver, it delivers 24-bit, 20Hz to 20kHz audio with practically no latency. This microphone can be used with up to 89 others when connected to the EW-D, and you won’t have to worry about distortion, lag, or interference, thanks to the receiver’s equidistant tuning grid.

Batteries Not Included. This transmitter does not come with batteries, but you can pick up AA batteries or the EW-D Charging Set. Single BA 70 rechargeable batteries are also available here. AA batteries power the transmitters for 8 hours while the optional battery pack powers them for up to 12 hours.
