For Journalists, Vloggers, YouTubers    2 x Transmitters with Built-In Mic & Lav    Ultracompact 2-Channel Plug-In Receiver    5-Hour Rechargeable Battery + USB

• The two-channel receiver allows you to use just one receiver to simultaneously receive signals from the two mic/transmitters, saving space on your phone shooting rig.

• Each transmitter is equipped with a built-in microphone and a 3.5mm mic input that accepts the included lavalier microphone.
• For a truly wireless experience, the transmitter can be clipped on clothing without having to wire yourself or your talent. You can also hold the transmitter in your hand and use it as a handheld microphone.
• The On/Off switch doubles as a mute button.

• For a more discreet setup, use the small lavalier microphone, which can be easily concealed away from the camera's eye.

• This plug-and-play system is easy to use. It comes pre-paired at the factory; connect it to your camera, turn it On, and you're ready to start recording.
• Dedicated gain buttons on the receiver allow quick and effortless adjustment of the signal level for each microphone independently.
• The transmitters have a display that shows signal strength, audio level, and battery life.
• The transmitters are powered via a built-in lithium-ion rechargeable battery. They can also be powered via USB, even while in use, giving you near unlimited operating time.
• The receiver is powered via the phone.

• Whereas typical analog wireless systems are susceptible to interference from TV and radio waves, the BoomX-D digital system avoids that by operating in the 2.4 GHz frequency band, which occupies frequencies beyond those of television, radio transmissions, and UHF wireless microphone systems.
• The system automatically changes transmission frequency to mitigate noise and dropouts at a line-of-sight distance of up to 164 feet. For optimal performance, environments with limited Wi-Fi/2.4 GHz traffic and minimal physical obstructions are recommended.

Related Questions and Answers

Q: 1. Can I purchase multiple bluetooth mics to use for this if they're on the same channel?

A: No. You can only use one (included) microphone transmitter with the included receiver. To receive from two microphones you would need two seperate receivers. The frequency used by this Comic WS50H is not Bluetooth, it is between 520 and 526 mhz.

Q: 2. Can you connect an external mic such as the Rode Video Mic? I saw a review that stated this might be an issue.

A: While it is possible to connect the VideoMic to the Boom transmitter, we can not guarantee proper functionality since certain mic transmitters have specific voltage and impedance requirements from the mics which could create noise issues if not matched.

Q: 3. The lightning jack looks almost flush with the bottom of the receiver. Will the Comica receiver fit on an iPhone 11 that has a case on it? Does the case need to be removed in order for the lightning connector to connect properly? The case spec says it adds 3.5 mm to the phone.

A: You will most likely need to remove the case to use the Comica Boom X

Q: 4. Can you use this on a DSRL?

A: The Comica Audio CVM-WS50H Wireless Handheld Microphone Bundle for Smartphones will not be able to connect to a DSLR with the included 3.5mm TRRS cable. A TRS to TRRS adapter, such as the Kopul MC-TRRSA 3.5mm TRRS Female to Right-Angle 3.5mm TRS Male Adapter Cable (B&H # KOMCTRRSA), would be required.

Q: 5. Is this receiver interchangeable with the transmitters from the USB-C receiver kit?

A: Yes, as long as the model is the same.

Q: 6. Does it work with iPhone 12 since it has no jack port?

A: Yes it does work with a iPhone 12 all you need is the apple adapter from 3.5mm (jack) to Lightning connection. https://www.bhphotovideo.com/c/product/1280795-REG/apple_mmx62am_a_lightning_to_3_5mm_headphone.html

Q: 7. Should this work with the DJI OM4: in particular, can the OM4 balance with the receiver attached to an iPhone XR? Should it, as external audio, work with the DJI Mimo App?

A: We have not tested the DJI OM4 with the Comica Boom-X wireless mic system on an iPhone XR to be able to say whether or not there will be any issues with balance on the OM4. The external mic will work to deliver audio, but the Mimo app does not provide control of the parameters such as turning the volume level up or down.

Q: 8. Hi, Ive small question is the audio recorded mix or split?

A: Based on the manual, when using two transmitters the audio should be split left and right.

Q: 9. Will receiver compatible with iPhone 6S Plus?

A: Yes, the receiver included with the Comica Audio BoomX-D MI2 is compatible fro use with iPhone 6S Plus.

Q: 10. How can we use this for zoom meeting plugged into a phone? There is no audio so cannot hear others, but they can hear me.

A: Try starting the app on your iPhone using the built-in mic (without connecting the wireless system). Once the app is already running, then connect the wireless receiver to the iPhone. That may work. You will probably need to use headphones to hear the others in the Zoom meeting. Apple iOS devices may not work with an external mic when using video conferencing apps that have two-way audio, but do work for standard type video and audio recording. Comica has not provided any details about compatibility for this wireless system with Zoom meetings and Apple is constantly making changes to the software. We cannot confirm compatibility as results can vary depending on the version of the phone and operating system. However, we can confirm that the Comica BoomX-D DMI2 does work for recording audio and video with audio on the iPhone.
