Sennheiser MKE400-II I used this a few times for work, but I no longer need it, so I'm selling it. The sound quality is, as expected from Sennheiser, clear, and the directionality allows for beautiful recording of voices. Using the windscreen cuts down on wind noise. It's also great that you can monitor the sound while listening through headphones. This prevents problems like the sound not being recorded or noise being present. Also, the microphone automatically turns off when the camera is turned off, so you don't have to worry about forgetting to turn it off. The low-cut filter and the 3-stage gain sensitivity switch are also features unique to Sennheiser. It can be used with a wide range of devices, including action cameras, smartphones, DSLRs, and mirrorless cameras. Weight (g): 93.5 g Audio Output: 3.5 mm jack, screwable Max.
