Comparison of the Boya BYM1 Omni-directional microphone vs Sennheiser ME4 cardioid microphone. As Boya BYM1 falls into the budget category of lavalier microphone and Sennheiser can be considered as a premium or expensive lapel microphone, this will give a good idea about purchase decision.

Sennheiser ME 4

Small cardioid clip-on microphone especially for speech applications in noisy environment. Feedback-rejecting.High speech intelligibility. Easy attachment on clothing.

The ME 4 is a sub-miniature clip-on lavalier microphone which is suitable for speech applications in noisy environment. It is equipped with a cardioid capsule and has therefore a high feedback rejection.
- High speech intelligibility
- High feedback rejection
- Easy attachment on clothing
- Mini jack for bodypack transmitters from evolution wireless series

You will get to listen to test audio coming from both these lavalier mics & compare the audio quality of these microphones and see which one performs better than the other.

The frequency response for Sennheiser ME4 is 50hz - 18KHz, while for BYM1 is 65Hz-18KHz. So Sennheiser has a bit more advantage here.

For audio test we used the 3rd set form Harvard sentences, which includes 72 different lists of 10 lines each. Of all the sentences in the lists, each contains only a small amount of words – never above 12. The researchers tested cellphones, VoIP, and several other technologies by speaking sentences from these lists. While a variety of speech testing words exist, the Harvard sentences are a timeless and popular set.

And the Equivalent noise level for BY-M1 is 75 Decibel and Sennheiser in this case will be more like 31 decibel.

Boya M1 indeed isn't able to produce the quality of audio which was recorded using Senneheiser ME4, but using a sound correction software like Audacity you can bring the quality of that audio as close as possible to ME4.

Many new content creators will benefit from learning applications like Audacity & understand how to clean the audio post recording irrespective of the microphone used.
