Tune your Layla to your DAP the way it was meant to be heard...

Jerry Harvey recently developed a specifically tuned EQ setting for the Layla AION IEM to be used in conjunction with the Astell&Kern SP1000 DAP music player.

Jerry Layla EQ Preset

The equalizer file is simple to use and has basic and advanced control parameters depending on how specific you want to get in tuning your device. The basic parameters have a graphic equalizer, whereas the advanced settings give you a lot more control.

The advanced settings contain a parametric EQ, which allows you to adjust the width, the frequencies, prefix frequencies, etc. There's enough of them that you can hit some sweet spots or resident peaks in both headphones and earphones.

The reason Jerry created an equalization file for the Layla is that every passive headphone and earpiece on the planet can use some sweetening. With a passive crossover we can get really close to having the product dialed in, but there's always going to be a 20 - 25% factor to make the earpiece sound sweeter if you had more precise equalization.

Jerry Harvey essentially took the frequencies that he could not control with the passive crossover - around 8k where the “S’s” and “T’s” (sibilance) are. He also added more bottom end so you can set the bass attenuator at 1-o'clock and add some punch to the music, due to the fact that the Layla is not a heavy bottom-end earpiece. Lastly, he took some of the masking frequencies out at 180, brought the vocal forward a little between 500 and 700, and brought up some of the air above 14k.

These are just some of the things you can do with the SP1000 EQ file to sweeten up an already good sounding headphone or earphone. You can adjust it however you want to, regardless of the presets by JH Audio and tailor the sound to your preference or taste.

This EQ file will work and translate across all of the Layla generations because they've been very true to the frequency response and the tonality of the original Laylas. 

If you hear something in the frequency response of a headphone or earphone that you don't like, it is possible to find that frequency and cut it out manually. For instance, if the problem frequency is around 4k, you can create a narrow curve around that EQ spot and lower the level. While listening to music, you can manually boost that frequency to hear if you’ve pinpointed it or not. If not, then you can zero the EQ curve and try the next frequency range on the file until you find the frequency that’s bothering you and cut it out (by negating the dB level).
