Take the hassle out of vlog and interview audio with the Sony ECM-W2BT Digital Bluetooth Wireless Microphone. Because it's wireless, it allows stress-free shooting and delivers clear audio in diverse environments, without worrying about the direction of the mic or the distance from the mic. Clear Audio Pickup from Any DirectionThe ECM-W2BT can be positioned close to the speaker's mouth with a clip. The omnidirectional mic capsule also helps to pick up your voice clearly wherever it's coming from, so there's no need to worry about which way the unit is facing.Effective Noise Suppression During Audio TransmissionUnlike conventional analog audio transmission, you'll never need to worry about cable signal interference. Just pair the ECM-W2BT with any Sony camera that supports a Digital Audio Interface via a Multi-Interface (MI) Shoe for clear, low-noise, all-digital audio.Simple Audio Optimization for Any SourceAn attenuator function lets you easily adjust recording levels appropriately to match the source. Simply flip a switch to reduce the level of very loud sounds or amplify quiet ones, for optimized audio levels. Clear Sound Even Outdoors in the WindThe unit comes with a windscreen, allowing comfortable recording when shooting outside. Just attach the windscreen to the mic, and it effectively reduces wind noise as well as breath noise, for clear and stable sound even when shooting outdoors on a windy day.Bundle Includes:Sony ECM-W2BT Digital Bluetooth Wireless MicrophoneSony ECM-LV1 Compact Stereo Lavalier Microphone30W PD Two-Port Power Adapter
