Sony ECM-W2BT Camera-Mount Digital Bluetooth Wireless Microphone System for Sony Cameras

Take the hassle out of vlog and interview audio with the Sony ECM-W2BT Camera-Mount Digital Bluetooth Wireless Microphone System for Sony Cameras. 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. 


Stable Bluetooth audio wireless communication - The ECM-W2BT offer a stable Bluetooth wireless solution to capture crisp clear audio from up to 650 feet (200m)  away and is ideal for use on Sony cameras that employ either a digital or analogue MI (Multi Interface) shoe1 for cable free connectivity.  When connected to a digital MI shoe camera, the receiver converts the audio from analogue to digital and does the digital signal processing, sending the digitized audio to the camera for a low-noise high-quality recording.

Compatible with a wide selection of cameras and recorders - The ECM-W2BT is not only ideal for vloggers and content creators capturing video on a camera or camcorder, but can also be used for external audio recorders, mobile phones and personal computers4. The ECM-W2BT is supplied with a 3.5mm to 3.5mm audio cable that easily connects the receiver to cameras and other devices that have a 3.5mm microphone input jack. 

High-quality omni-directional mic capsule for clear sound pickup - The Transmitter has an advanced omni-directional microphone  capsule to capture clear sound recording from any direction. A fuzzy wind screen is also included and can be attached to the microphone to reduce wind noise if required. It also includes a 3.5mm mic jack so other microphones like the ECM-LV1 Lavalier Stereo Mic can be attached or any other compatible mic with 3.5mm connector. The transmitter also includes a convenient clip that can attach to clothing.

Transmitter attenuator switch adjusts audio pickup level - An attenuator switch on the transmitter is provided to adjust audio level pickup and is useful when sound is excessively loud or too low. Three attenuation levels, 20dB, 10dB and 0dB, can be selected depending on the sound source volume. The 20dB setting allows recording of loud sound with reduced distortion, while quieter sounds can be amplified for recording at the 0dB setting. Using the attenuator function allows appropriate audio levels to be recorded. The best way to set the audio level is while monitoring the audio level meter on the camera the volume on headphones connected to the camera.

Stable communication up to 650 feet - Through improved wireless connectivity the stability of the connection between microphone and receiver has been increased, even in the presence of obstacles or in crowded environments with multiple wireless activity taking place. In locations with good visibility, communication is possible at up to 650feet (200m)1, significantly increasing the flexibility of audio recording.

Wind screen included - The included windscreen can be used with the ECM-W2BT to reduce the wind noise that occurs when strong wind or breath impacts the microphone. The speaker's voice can be recorded clearly and stably, even when shooting outdoors.

High-audio-quality aptX Low Latency Bluetooth codec - Communication speed and range have been significantly improved, for increased convenience. The  Qualcomm® aptX Low Latency codec is used to provide both high-quality audio recording and low latency.

Terminal protection holder keeps units together and acts as mic stand - A supplied terminal protection holder keeps the transmitter and receiver together when not in use and protects the terminal from damage when in your camera bag. The holder can also support the transmitter as a stand when placed on a flat surface like a table to capture sound from multiple directions. This could be useful when needed to record groups or meetings.

Three sound pick up patten options - The ECM-W2BT offers ultimate creative freedom thanks to its sound acquisition functions. Three sound pick up modes - MIC mode, MIX mode and a RCVR mode - allows the user to record sound and ambient sound based on their desired preference. MIC mode will only pickup audio from the microphone transmitter so only the subject audio is captured. RCVR mode only picks up sound from the internal microphone at the receiver, so the user can record audio of themselves. MIX mode picks up both transmitter and receiver audio which is useful when audio from both the subject and the user is desired.

Compact, lightweight body design resistant to dust and moisture - The compact transmitter clips discreatly beneath clothing and is easy to hold, weighing only 0.95 oz. (27g) and measuring 1.2” x 2.66” x 0.75” (30.6 x 67.6 x 19mm). The receiver has a low profile when mounted on top of a camera’s MI or hot shoe weighing in at only 0.98 oz. (28g) and measuring 1.34” x 1.13” x 2.09” (34.0 x 28.7 x 53mm). To match the rugged performance of Sony cameras, both the transmitter and receiver are dust and moisture resistant.

Rechargeable Lithium Ion battery for long shooting duration - Both the transmitter and receiver have a built-in rechargeable Lithium Ion battery that delver long recording times. When even longer operation is needed, the battery assist function via the power supply from a compatible camera’s Multi Interface shoe enables the user to operate the receiver for up to 18 hours.

Recommend use with ECM-LV1 stereo lavalier microphone - The ECM-W2BT mic supports stereo audio output input and an external 3.5mm stereo mini-jack to allow for stereo sound pickup, so it can be used in combination with the stereo-capable lavalier microphone such as the ECM-LV1, as an unobtrusive microphone that can easily attach to the subject’s clothing and record sound with increased realism.

LINK and power lamps - For easy reference, the ECM-W2BT includes a LINK lamp to notify the user of the status of the communication between the microphone and the receiver and a POWER lamp to show the remaining battery charge.
