Polsen MO-IDL2-MK2 Overview

Designed for mobile journalists, podcasters, vloggers, and live streamers, the Polsen MO-IDL2-MK2 provides a cost-effective solution that simplifies recording two-person interviews or dialogs. It comes with two lavalier microphones that let you capture clear and accurate speech directly to the single mic input of your DSLR/mirrorless camera or audio recorder. It is also compatible with iOS/Android smartphones or tablets that are equipped with a 3.5mm headphone jack.

The microphones feature an omnidirectional polar pattern that picks up sound equally well in every direction, ensuring that the level of your voice remains consistent, even when moving your head while the mic is clipped to your shirt or lapel.

The microphone's compatibility can be changed with the flip of a switch that toggles between Camera and Phone output modes, switching the output of the mic to either TRS or TRRS. The cables between the mic capsules and switch are 3.5' long for a maximum of 7' apart. The cable between the switch and the camera is 20' long, and is terminated with a 3.5mm TRRS connector. A 3.5mm-to-1/4" adapter is also included to plug into cameras like the Blackmagic Design Cinema Camera.

A battery comes installed so you can use the MO-IDL2-MK2 with cameras and devices that do not provide power to the microphone. The included alligator-style clip holds the lavalier mic firmly in place and the foam windscreen helps reduce unwanted wind noise and vocal plosives. A storage pouch is provided to hold everything neatly during storage or transport.

Two Lavalier Mics Tailored for Speech
  • The MO-IDL2-MK2 is optimized for the voice. It produces a rich and natural sound, whether you’re speaking to a live audience or recording audio for video.
  • The microphones feature an electret condenser element with a smooth frequency response and wide dynamic range to effectively and accurately capture speech.
Function Switch for Versatility
  • The function switch configures the MO-IDL2-MK2 for recording to either an iOS/Android smartphone/tablet (with a 3.5mm headphone jack), DSLR/mirrorless, camcorder, or computer—without the need for separate microphones to record to each type of device.
Battery or Smartphone Power
  • When the function switch is set to the Camera position, the included button-cell battery provides the power you need to record to a DSLR, camcorder, computer, or tablet.
  • When it's set to the Phone position, it turns off the battery to preserve battery life, and the microphone operates using the plug-in power from your smartphone.

Polsen MO-IDL2-MK2 Reviews

Sounds good with limitations

By Tom

These omni lav mics sound good and have a great price but have no balance adjustment. The 2 mics are not stereo but combine the signal into one mono feed. I used them as 2 table mics to pick up 3 people and pickup range worked well.

Fair value for money, I suppose

It's hard to truly rate something like a budget lavalier when audio quality and price point are so closely tied. I think this was fair value for money. I was using these in conjuction with the Rode GO II mic packs (since the Rode lav wasn't available at the time of purchase). While it worked, the internal mics of the Rode GO II were far superior. Buuuuut, as stated earlier, price plays into that and this lavalier set up was a fraction of the Rode solution. If you want audio that's more clean than your internal camera mics, I don't think you'll be disappointed for the price.

can I plug this into a Sennheiser transmitter?

can I plug this into a Sennheiser transmitter?
Asked by: David
No, unfortunately not. The Polsen MO-IDL2-MK2 Dual Omnidirectional Lavalier Microphone has a 3.5mm TRRS connector that is not compatible for use with the 3.5mm TRS locking input on a Sennheiser transmitter. As a compatible alternative for a dual lavalier mic, you can use the Saramonic DK3A2 Dual Mini Omni Lav Mic with Locking 3.5mm for Transmitters, Recorders, Cameras, Mixers with Plug-In Power (B&H # SADK3A2).

Will this microphone pair function as a line input on a Zoom H1n to record 2 people?
Asked by: Wayne
The Polsen MO-IDL2-MK2 Dual Omnidirectional Lavalier Microphone is intended for use with smartphones and cameras. Because of the mic's 3.5mm TRRS connector, it may not function properly with the input on the Zoom H1n Portable Handy Recorder and may require the use of an adapter such as the RODE SC3 3.5mm TRRS Female to 3.5mm Right-Angle TRS Male Adapter Cable (B&H # ROSC3) to convert the plug from TRRS to TRS. As a better option for the H1n, you can use the Polsen OLM-20 Dual Omnidirectional Lavalier Microphone (B&H # POOLM20), which is intended for this purchase.
