Review of JH Audio’s New Layla AION IEM

Jude posted a video review of JH Audio’s latest iteration of their 12 BA driver 4 crossover Layla IEM.   In this iteration, they are using 3D printing to create the audio channels rather than discrete tubing as in the original versions.  This reduces the size of the IEM down to a manageable size as many folks didn’t like the size of the prior models.  Personally, I don’t have an issue with the size of my Gen 1 Laylas but I also do use them as my mobile IEM.  Additionally, one has to assume the new manufacturing process significantly reduces the labor necessary to build them.  It will be interesting to see graphs on the audio performance of the 3D printed channels versus the individual tubing.  Enjoy the video review below.

JH Audio Custom Layla IEM Review

Eric Neff has posted a nice review of his custom Layla IEM on


Pros: Adjustable bass means a wide range of uses and personal styles are possible with one pair of CIEM’s
4th order crossover concisely controls the twelve drivers per side.
Perfect frequency phase delivered by three independent steel tubed bores.
Impeccable fit and finish. Custom fit was perfect as received!

Cons: Price. $2195 in my version is the low end. They scale up with materials options to nearly $3k
Cable is thicker to accommodate the bass adjust. Some people may prefer a thinner option.
No iPhone controls or microphone available at this time.

Layla review

JH Audio & Astell&Kern Siren Series Full Metal Jacket Line Announced!

Jude over at Head-Fi just posted a video of the updated JH Audio Siren Series IEMs.  Included in this video is the updated Layla, Angie and Roxanne.  Unfortunately, Jude doesn’t provide side by side reviews with their prior versions since he just received the units. The new Rosie 6 driver IEM was also announced along with a small review from Jude.  The Roxanne obtained an additional crossover standardizing the 10-12 driver models to a 4-way crossover.  I assume the new Rosie is a 3-way since it only had three groups of drivers. The Layla now has a titanium housing will all of the other Sirens are made from aluminum. All of the models now have new cables made by Moon Audio. No discussion on any improvement to the SQ but the connectors have upgraded.

I state that this is an update and not an upgrade.  The only changes on the Layla and Angie were the housing which I don’t feel is an upgrade.  Since the audio travel through the same stainless steel waveguides the change in housing material should have little to no impact on the SQ.   I suppose the additional crossover in the Roxanne might be an upgrade but we won’t know for sure until we receive some side by side comparisons.
