About The Headphone Database
HypetheSonics’ headphone database is a self-consistent set of measurements of some of today’s higher-quality in-ear monitors and earbuds. All measurements on this database are produced using the GRAS RA0045 coupler. Unless otherwise mentioned, all IEMs are measured with SpinFit silicone Cp100 or Cp800 eartips (depending on nozzle diameter). The database includes information such as sound pressure level versus frequency, distortion (at 80 dB and 94 dB @ 500 Hz), impedance (where relevant) and impulse response. In addition to the measurement data, various tools are available to help in comparing headphones against other headphones, and against given target functions. These tools are explained in detail in the main ‘How To’ section (top right menu).
