I didn't expect much, other than a decent Bluetooth headphone implementation from a brand (JBL) that usually doesn't suck. But I have to admit to really liking these headphones far more than I expected to. If I were designing a pair of consumer Bluetooth over-the-ear headphones with a few gimmicks like bass boost and noise cancelling with ambient sound pass-through, and a handy optional wired connection, I would have been quite proud to have come up with this product.

The only issue with the comfort is the heat that is naturally trapped by the well-done passive noise seal around the soft (protein?) but sufficiently foam-filled ear pads. I can wear these for hours, with the only downside being hot ears.

The sound is fun. These are no audiophile headphones; these are just fun toys for some mix of music and zoom calls (and blocking out the world).

I wouldn't normally write a review for a product like this, but since no one else has written a review here for these, I thought that it couldn't hurt, just in case you're considering this model. I've been using them for months, and they've been all over the country with me, and I have zero regrets purchasing these. They aren't going to replace anything in my collection, but they are handy for sitting on the porch (like I am now) blocking out my wife's YouTube watching; for doing a zoom call on the road; or for watching a video without anyone else around me being bothered by the sound. And for pop / R&B / rap music, they're pretty much the sound signature that the music is designed for (which is either a compliment or an insult, depending on your point of view).

I do like these headphones. I use closed back headphones at work (my coworkers don't like the noise), and at home in bed (my wife likes to sleep). However, these do not have the high degree of sound seal that I expect from a closed back headphone, so if that's why you're considering them, then keep looking.

I also tend to listen to music at very low volumes. Sure, I'll boost the volume on a track for the fun of it, but generally, I like my volume really, really low. But I still want to hear all of the detail, and all of the color. I would say that these headphones provide the detail at low volumes, but totally lose the color.

Crank them up a bit, though, and they're amazing. (And of course, they'll leak noise.)

Frankly, these are overpriced for what you are actually getting. At $150, they'd be a no-brainer. At $250, it's debatable. At whatever-they-are-actually-going-for, the value for money just isn't there. (Of course, that can be said for a great many headphones.)

They're nice, though. They're just not great. (At least not for the things that I value.)

JH Audio has an entire line of custom IEMs, and a cult following. I've had a friend pushing me to get a pair of custom Layla IEMs since they came out; he was one of the early customers, and he still raves about them (even years after they were stolen from him). I had not intended to purchase them, but the Black Friday special was too tempting to skip, so after a quick visit to the ear proctologist for a set of molds, I sat back to wait. Normally, these take less than two weeks, order to delivery, but I was in no rush -- and I didn't want them to be in a rush, either. The holiday season was busy enough that they ran out of balanced cables, but those followed the IEM delivery by just a week or so.

You can configure these in a myriad of different ways and colors and materials and images and so on. I picked one of the "Signature Designs", to save myself the trouble of second-guessing all of my design choices.



This one is called "The President":



(Thankfully, this "The President" is neither bright orange, nor tone-deaf.) There was still some minor amount of customization possible, but the real customization that I was after was in the shape of the inserts:



It came in a different package than the A&K Laylas, but I find packaging to be boring; I'm interested in what is inside. One positive: The same (and quite popular) carbon fiber case is included, and it's customized with your name, or whatever you choose. It's actually a metal case that is itself encased with a carbon fiber finish, which is beautiful, but mostly overkill, due to its size and hardness -- and the inside is only padded top and bottom, so you'll still want to place the Laylas into their protective felt pouch (included). I ended up using a few smaller hard-shell padded cases instead, depending on what I was carrying.



I had a week to enjoy these with the included single-ended 3.5mm cable. The "memory wire" feature is nice, but not as aggressively powerful/rigid as I like; no complaints, though. The cable is attractively silver and braided, and has a 2-dial bass adjuster. To get started, you just have to connect the 4-pin screw-on plugs from the cable onto the IEMs (although this was probably already done when I received them). The screw-on feature is nice, in that it provides some additional surety to the IEMs "staying on" the cable, but it's not a guarantee -- sometimes the screw caps can loosen, so it's worth checking them regularly.



My first impressions listening, on an old Pioneer XDP-30r: Yeah, these suck. Unbearably muddy. Quite disappointing, until I realized that they had shipped the bass pots wide open (i.e. at the 5 o'clock position). I dialed them all the way down to 7 o'clock, and *poof!* the headphones were singing.



I have a nice, quiet, separate listening space (wired for 13.4.6 speakers) with a Woo Audio WA5-LE headphone amp as well, so I had some time to test some tracks (still on the single-ended output). While listening to Lenny Breau, "The Hallmark Sessions", I heard footsteps behind me, and whipped around to see who was there. No one -- I was alone in the building. This happened a few more times. Finally, I backed up the track a bit, and sure enough, the footsteps were on the track.

Now, to be clear, I have listened to this recording at least a hundred times. On nice Grados, MrSpeakers (or MrsPeakers?), etc. Same DAC. Same amp. No one ever snuck up behind me before like that, though. I never heard those footsteps before. I was pretty impressed, but not having bought every piece of audio gear from every tradeshow, I'm still fairly easy to impress.

This is a good time to add that, despite being small enough to be IEMs, and having only a 20 ohm impedance, these IEMs really seem to enjoy having a massive truckload of amp behind them. They sound fine with a portable DAC, but they really come to life with a big amp -- even at low volume.



That said, the iPhone 8 drives it beautifully on the single-ended cable using the Alpha & Delta Lightning Adapter (from: https://www.alphandelta.com/product-page/alpha-delta-lightning-adapter).

So, finally, let's talk about the important stuff, like sound. These things have a bajillion (12) drivers each, arranged as 4 low, 4 medium, 4 high, coming out of three tubes. The drivers are "custom for JH Audio", which means that they are some OEM part with a slight tweak so that you don't realize that they're the same part that you can get from an electronics distributor for $1.49 each (which is a completely made up number, but far, far more expensive than most IEM drivers). The custom shells fit fairly well in the ears, providing the necessary pressure seal. It helps that the Laylas are so large to begin with, that they don't have to stretch much to fill the necessary space to provide that proper seal.

And the sound is: Full. Detailed. Luscious.

I'm used to custom IEMs, but these are certainly a cut above. (And a cut above, they should be, because I had to sell a kidney to get them.)

Luscious is probably the best word for them. If you've spent time recording vocals, you'll know the sound that you get when you have the singer re-record the same part over and over, and then layer and mix those tracks together. I'm fairly certain that my ears are telling me the same thing here: That the redundancy of drivers, with perhaps the slightest offsets in timing, is providing a much more luscious sound.

Yes, it's a trick. But it's a well-done trick. The timing has be very good, because any sloppiness, and you end up with mush sound.

And the bass? That's the reason for the four pins on the IEMs: Two of the pins are apparently dedicated to the bass, and the variable resistors in the cable allow you to dramatically reduce the current to the array of bass outputs. Note that despite marketing concepts, there is not (and can not be) any "bass boost"; electrical signals don't work that way. Instead, these IEMs are built / tuned to have massive (way, way too much!) bass, and then they thoughtfully include a cable that allows you to dial the bass back down to more tolerable levels.

And much of those other intangible terms (depth, width, breadth, height, and so on) are similarly tricks. Yes, well-done tricks, but tricks nonetheless. All of them are timing related, because humans only have two audio inputs (ears), and the brain uses extremely subtle timing differences to imagine and to picture the location of the sources of sounds (because our ancestors who couldn't do so quickly enough all got eaten by wild animals before they could reproduce and pass on their non-audiophile genes). So our brains render one-dimensional audio data into a three-dimensional image, and that is what we believe that we hear.

And the Laylas do it beautifully. More beautifully than any other IEM that I have ever listened to.

And as beautifully as a good pair of full sized, closed-back headphones.

I'm not willing to say that they're as good as a high-end, over-the-ear, open-backed headphone, but it's hard for me to imagine being able to put better audio rendering into my pocket, and listening to it without other people around me hearing it. (I'm used to customs already, so the incredible benefits of custom-fitted IEMs is wonderful, but it's not earth-shattering for me. If you have never tried customs, then you can start by making your own for about $10 to see if you like them, but read up on the process before you try it.)

I haven't used these yet for performing music, but I'm sure that they'd do well for that. However, I'd seriously consider getting the JHA Ambient FR custom IEMs instead, unless I were using these in a studio.

These are going to be my go-to travel IEMs (coming up soon), and probably my go-to-everything-but-my-desk headphones for a while. And probably often-at-my-desk as well.

A number of posts on the various Layla threads here (going back five years) were talking about quality issues. So far, I have none to complain about. I treat my gear well, but so do a number of the people who have had issues with the older Laylas, particularly early on in the production cycle. I am hoping that all of those issues are long behind JH Audio, and the quality is going to be much more dependable moving forward. I'll update this review accordingly.

These aren't "flat as a ruler" monitors, either. You may be able to use them for technical work, but you'll likely need to spend some time EQing them first. These are made for listening to, not for performing mixing surgery.

In conclusion, are they worth it? No, absolutely not. But to be fair, none of the high-end audio gear is "worth it". This is a hobby in which the incremental return on investment is so near zero as to be laughable. But we're talking about subjective enjoyment, and I am enjoying these Laylas. My advice before considering a pair of anything so expensive is to try them out (e.g. demo the universal version) in person, with your DAP/DAC/amp of choice, and see how they work for you.

I've had this player for a long time. It has a ridiculous number of features, including Bluetooth and WiFi and Tidal and remote apps and MQA and so on ... but I don't use any of those. What I do use is a massive amount of storage on a micro-SD card, and the balanced output. So my review won't be a very good reflection of the capabilities of this player, but just the tiny slice of stuff that I actually use.

The funny thing is that I have almost no complaints about the player. Sure, it's not a tube amp, but on the other hand it fits in my pocket and the battery lasts and lasts.

(Writing this while listening to Aretha Franklin on the Pioneer XDP-30r over Laylas on the balanced out, bass turned way down.)

I don't get to listen to open-back headphones very often. In the office, my office-mate hates them. In bed, my wife hates them. But with the office-mate out of the office this week, the PS1000 is on the desk, and I stumbled onto this review thread (while simultaneously hearing the first flaw in these cans) and though: "Why not?"

These are Grado style. They're not my only Grados, and I love Grados. Who would buy Grados? I wouldn't ... but a very knowledgeable friend suggested a lower end pair a decade or so back, I bought them, and I really loved them (on a Ray Samuels amp, for example). But Grados are different ... no ads with half-naked women, no professional athletes paid to wear them in public, no clique of obese business travelers paying too much for them, and no hyper-inflated muddled bass focus with famous artists wearing them before selling out to Apple.

Nope, Grados are their own thing. They march to the beat of a completely different drummer. And that drummer, apparently, has incredibly good hearing.

My description of the PS1000 sound is simple: Pure. They're as pure a sound as any headphone has ever delivered to my ears. Up until today, I've never noticed a note that they couldn't carry, or a sound that they wouldn't separate for my ears to distinguish. Sure, you call them simplistic, because they are. That's what Grados do best. Straight through sound.

I also love that they have such low impedance. These are meant to be useful in the studio, without an amp to distort sound and/or smooth things out and/or warm things up.

I don't like that they're not balanced, but Moon Audio fixed that for me -- and currently has the PS1000 on sale: https://www.moon-audio.com/grado-ps1000e-headphones.html ... I have the PS1000 on a Black Dragon cable terminated with a balanced 4-pole mini-XLR. (You'll need to specifically request the balanced mod.)

I also have a custom leather padded head band for them, because the stock one is just too thin.

I use the standard pads from Grado, but there are options out there; I'd love lambskin on these, but I'm afraid to change them out, because the sound is just so good with the standard pads. (I recently replaced the original pads ... with a new set of the same.)

And the worst problem was that the rod blocks kept on slipping, but Shipibo Audio in Poland makes custom aluminum blocks for Grados, which I have had for a year now, and I am now super happy with the result. (Seriously, Grado, you couldn't come with these standard?) Here's the seller, but they don't currently have the blocks listed, so email them to ask if they still sell them: https://www.ebay.com/usr/shipibo-audio (I will add that they have very good service.)

Now, as I was reading the other reviews, the first fault I've ever noticed with these (now old) headphones came to light ... quite the coincidence. I was playing Ray Charles "Sinner's Prayer" with B.B. King on the "Genius Loves Company" album (CD FLAC from Audirvana on Mac Pro via Topping D50 to Woo Audio WA5 balanced out) and two vocal notes at 04:06 and 04:07 (-00:20 and -00:19) caused distortion that I've never heard before. What?!?! I checked several times, and it's 100% reproducible! So I A/B'd against some other great cans, and ... crap, it's in the recording. I know the sound, too, because I use condenser mics for recording, and know how easy it is to blow the peaks. How is it that I never noticed this flaw in the recording on any other headphones?

Ask Mr. Grado. His cans are perfect.
