BOYA BY-M1 DM vs BOYA BY-M1 | Which to Buy

I want to buy the Boya BY-M1DM Dual-head clip-on mic, but is it as good as its single-head counterpart,  the BOYA BY-M1?

Let's check the specs...

About Each Mic Routing to Discrete Channel... What this be an issue? Two different coming from the left speaker and the right speaker. I guess if I'm using it as a single person, I will need to clip the two mics on my collar. So the answer is... no problem.

The Good: Specs are the same

Both models have the same specs other than the cable length and one more mic.

The Bad: Requires battery

So both require the LR44 battery 🤔... not very exciting anymore... my current Logitech H111 headset and the included Samsung Galaxy headphones don't need batteries. 😡Not knowing when the batteries will run out and carrying spare batteries are very inconvenient and unnecessary extra steps.

Conclusion

It's good if I am using as a professional videographer connecting the mic to a camera or camcorder for a client project.

However, I am now looking for a mic for my own projects using mainly the smartphone, and sometimes (rarely now) the camera or camcorder.

Put the purchase decision on hold... while I go find a batteryless alternative.
