About JH Audio
As we have learned from the interview with Jerry Harvey a little while ago, JH Audio was founded 2008. Jerry also founded and owned Ultimate Ears and has designed some of their most reputable products, including the Triple.Fi. If you haven’t read the interview yet, you can do it here. JH Audio is a CIEM company seated in Orlando and mostly works with professional musicians, such as Slash, Will Smith and many more very famous groups and artists. His artist roster reads like the who is who of the music industry. They of course also offer their line-up for the regular folk around. His past creations have been very well received by many audiophiles around the globe. A few months ago we’ve reviewed JH’s Lola custom in ear monitor. You can read up on this article here.
JH Audio is one of the brands that also pushes a lot of own technologies and patents them, like FreqPhase or D.O.M.E., to further enhance their performance and give the best possible sound-reproduction to their customers.
Here’s a video of Jerry explaining his technologies and what they bring for the consumer:
Layla has been introduced by JH Audio quite a while ago back in 2015, so this is not a new IEM we’re reviewing here today. Layla still resides as Jerry Harvey’s flagship, and I tip my hat for this. We see a lot of other manufacturers launching new flagships in short time, not always to the liking of their customers. JH Audio sticks to their TOTL and I’m very happy they do.
Twelve proprietary balanced armature drivers are packed into each earpiece. Four drivers reproduce bass, four take care of mids and another quartet is here for high notes. All of the drivers are powered by Jerry’s own SounddrIVe technology.
Like most of JH Audio’s monitors, Layla’s bass can also be altered with the bass attenuator near the cable’s end. The bass pot gives low frequencies (at 60Hz) a boost of 13 decibels when fully turned up. When it’s completely turned down its bass is said to be totally flat. The internal crossover design is of fourth order and very sophisticated. She features three sound bores with Freqphase stainless steel tube waveguides.
Layla also uses the screw-able four pin connector like Roxanne or Lola. Personally I think this connector is really good. I would love to see more manufacturers include it with their monitors, as it simply is a lot more robust than MMCX or two-pin. The cable fits very securely when screwed on and it certainly looks like it could withstand being treated a bit rougher. I assume touring artists can vouch for that. Layla is one of the few monitors of JH Audio that is not offered in a universal form factor as part of their Performance Series.
Layla’s impedance is measured at 20 ohms, sensitivity is 117 decibels per Milliwatt and her frequency response goes from 10 Hertz all the way up to 23 Kilohertz.
