Shows that the frequency deviating up to 10 dB varies from 6-51000 Hz and the frequency deviating up to 3 dB varies from 14-441000 Hz. This is within the human hearing range which ranges from 20 Hz up to 20000 Hz. Meanwhile, the sound characteristic of Beats can be described as tight and has a strong low frequency. Hip-hop and dance music, the one with sampled kick drum sound, goes very well with the characteristic sound of the Beats. And those types of music are the type of music that Dr. Dre created and produced. So Dr. Dre actually designed the Beats' signature sound to complement the music he made. You can see the Beats' frequency response below. The first image shows the original signal played without Beats and the second image shows the signal after going through Beats. “Figure 2: Frequency response from the original signal” “Figure 3: Frequency response after the signal passes through the beats” We can see the bump from 60 to 100 Hz that characterizes the strong low frequency. There is also a boost in high frequencies to help make the sound "better". Design-wise, the Beats also deviate from traditional premium headphones
