The next generation in Binaural microphones have 17dB less noise (hiss) 10dB more sensitivity and 10dB higher max SPL than our standard model. They measure an amazing 19dB of equivalent self noise. This means that your recording will have noticeably less background hiss and greater dynamic range than previously possible with in-ear binaural microphones! Compare these to the best omnidirectional microphones anywhere and you will see why these offer the highest level of performance at fraction of the cost of other similar mics.
