Review on 🎧 SOUND PROFESSIONALS - High-Quality Low Noise In-Ear Binaural Mics for Optimal Audio Capture by Megan Smalls

Very very clean, no noise maybe down to -90dB or even lower with h2n zoom mini recorder. The only problem is I have to tape them to my ears or they will pop/slip. The quality is very very good, better than my $300 tascam with built in x/y mic, the results are much better than the roland cs20em binaural recorders, but it's not comfortable at all if your ears aren't the right size to have.
