    Periodic Audio Ti Review: Titanium Never Sounded So Good
    Periodic Audio is a company heavily grounded in science. They take an objective, bare-bones, approach to audio that revolves around R&D, not marketing. Such an approach is not one that is easily found these days and as is quite welcome. The Ti is Periodic Audio’s mid-tier IEM, coming in at a price of $200. Does Periodic Audio’s approach to creating IEMs result in competitive products? Or is the Ti just another middle-of-the-pack design?

    You can find the Ti for sale here for $200.

    About My Preferences: Heads up, I’m a person! As such, these words are my opinion, and they are tinged by my personal preferences. While I try to mitigate this as much as possible during my review process, I’d be lying if I said my biases are completely erased. So for you, my readers, keep this in mind:

    • My ideal sound signature would be an extended sub-bass with a leveled, but textured, mid-bass.
    • I have a mild treble sensitivity.
    Source: The Ti was powered like so:

    HTC U11 -> USB-C adapter -> earphones

    Sound Signature
    Sonic Overview:

    The Ti is Periodic Audio’s take on a proper V-shaped IEM. Emphasized bass and treble combined with excellent timbral characteristics make it a great all-arounder suited to tackling most genres. Its sub-bass extends well and has both rumble and body. Its midrange is expressive, though recessed, and is mostly neutral with a hint of warmth. The Ti’s treble is highly resolving, airy, and well suited to complementing its bass.

    Treble: Songs used: In One Ear, Midnight City, Outlands, Satisfy, Little One, Show Me How To Live (Live at the Quart Festival)

    The biggest complaint I hear about dynamic driver IEMs is one regarding their lackluster treble performance. Well, I can safely say that the Ti easily puts that argument to sleep. While it isn’t perfect, the Ti displays a natural and “effortless” treble that captures so much nuance. The last time I heard a dynamic driver IEM “sparkle” so well while maintaining a sound signature that was free from harshness was over a year ago while reviewing the Chord & Major lineup. But tonality aside, the Ti’s treble exhibits some impressive technical performance. It picks up many details that would otherwise go unheard and provides the “airiness” that makes the Ti so easy the listen to.

    Midrange: Songs used: Flagpole Sitta, Jacked Up, I Am The Highway, Dreams, Too Close, Little Black Submarines

    A core feature of V-shaped IEMs is their recessed midranges, and the Ti is no exception. Its lower-midrange is mostly neutral, having only a small amount of warmth to give instrumentation some weight and character. The upper-midrange has a spike in the 1KHz-2KHz range designed to give vocals and lead-instrumentation some separation and clarity. Overall, the tact with which Periodic Audio tuned the Ti is incredibly impressive, as evidenced by just how good the midrange sounds even when recessed.

    The Ti does not seem to have a significant bias towards male or female vocals, having merely a mild preference towards male singers. This is an artifact of V-shaped sound signatures and is something you can find in most popular V-shaped products.

    Bass: Songs used: Moth, Gold Dust, In For The Kill (Skream Remix), War Pigs (Celldweller Remix)

    The Ti’s bass is befitting of a V-shaped IEM. It has expertly-balanced mid and sub-bass presentation. There’s little to no bleed into the midrange at all, even at higher volumes and during songs with intense bass lines. The mid-bass is punchy, relatively quick, and naturally-toned. Be it the busy drop of Gold Dust, the bass guitars of Moth, or the sonorous bass line of In For The Kill, the Ti staged and manifested its bass flawlessly, at least to my ears. The Ti reaches very far down into the lower register and doesn’t roll off till well into the sub-bass’s deepest components.

    Packaging / Unboxing
    I do not have any packaging on me for the Ti. See this review for information about how Periodic Audio packages their IEMs. All of the IEMs that Periodic Audio sell use the same packaging (save for some changes to the text on the boxes from model to model).

    Construction Quality
    The Ti has the same exact build as the other IEMs in the lineup, at least externally (save for a difference in cap color). The housings are made of a polycarbonate: a light plastic that supposedly has zero internal resonance. The stress reliefs are made from a somewhat stiff plastic. It doesn’t feel like it does much to relieve cable stress in more extreme situations though. A softer and more pliable material may be more suited to get the job done here.

    The Ti’s nozzles have also been revised. Instead of featuring the colored wired mesh that the V1 used, all the Periodic Audio V2 IEMs use a finely-perforated plate that sits flush with the lip of the nozzle. The right side is colored red to give you a visual indicator of which channel is which.

    The cable has also been revised to not use metal parts on the cable. While there’s no difference in functionality, I do miss the small amounts of flair that they gave the V1 units.

    And speaking of cables, I think we should talk about the cables that Periodic Audio uses. They aren’t bad per say, they just don’t feel sturdy in a way that you’d expect from a $100-$300 IEM. Increasing the thickness, using a (reasonable) braided cable, or even adding a structural layer of sleeving would each be very much appreciated and add a lot to the fit and finish of the Periodic Audio lineup.


    The Ti is very comfortable, especially when using the foam eartips that were in the box. The housings are so light that they are barely noticeable when in use. I had no problems when wearing them for over three hours during a project at work. They even worked ok while jogging, though they do stick out a bit too far for comfort for my comfort during rigorous exercise.

    The Ti comes very well stocked, especially for a $100 IEM. Inside the box you’ll find:

    • 3x pairs of silicone eartips
    • 3x pairs of foam eartips
    • 3x pairs of dual-flange eartips
    • 1x airline adapter
    • 1x 1/4in adapter
    • 1x hard carrying case
    The carrying case is compact but still has plenty of room to easily store the Ti. The lid screws on and doesn’t seem to have any looseness issues that a more poorly-machined case might.

    1: Periodic Audio Mg ($100)

    The Ti is more V-shaped than the Mg is. It has a more emphasized treble and more prominent bass, extending well to the 50Hz range. The Ti trades in a very small of midrange presence for a treble sparkle and bass impact/rumble. Other than that the Ti and Mg share many, if not most, of their core characteristic tone-wise.

    2: Brainwavz B400 ($200)

    The B400 is more linear and provides a warmer midrange than the Ti. These two IEMs have very different sound signatures that really puts them in very different positions in terms of what they are aiming to do. The B400 is looking towards finding a flatter, but still fun, sound signature while the Ti throws caution to the wind and goes all-in on being V-shaped. The B400 articulates its midrange a better, but it doesn't blow the Ti out of the water like one might automatically assume in a BA vs DD match-up. The Ti’s bass is much more natural-sounding and impactful. While the B400 does an admirable job maintaining rumble, the Ti simply outperforms it with its full-sized dynamic driver.

    3: Magaosi K3 HD ($120)

    The K3 HD is one of my, and many others’, favorite V-shaped IEMs. Instead of tackling the task of creating an IEM using a single driver, or a single type of driver, the Magaosi employed a hybrid-driver configuration for the K3 HD: one balanced-armature driver to handle the upper frequencies and one dynamic driver to handle the lower ones. This contrasts the Periodic Audio approach in both principal and practice. While the K3 HD does have a somewhat better grasp on the upper-treble than the Ti does, it ultimately fails to create the perfectly cohesive sound signature that uniquely benefits the Ti. However, these shortcomings can also be explained by the price difference between the two products (the Ti is $80 more than the K3 HD).

    The Ti has an incredible sound signature. It was tuned with care and has no obvious or out-standing shortcomings. While it could certainly use a reworked body and cable to add a little more durability, it isn’t in immediate danger of spontaneous failure, making it suitable for daily use. The Ti’s notable performance, easy to listen to sound signature, and competitive pricing has earned it a place in my personal IEM rotation. I highly recommend it to listeners who are ready to jump into Hi-Fi Audio, or are just fans of V-shaped sound signatures and want to get one of the best IEMs for it around. Keep up the good work Periodic Audio!

    As always, happy listening!

    Pros - Weighty and fast bass experience, detailed treble without being splashy or peaky
    Cons - Mids might be a tad thin; V shaped signature might have mids that are too recessed for some
    Before I begin the review, I would like to take the opportunity to thank Dan and team at Periodic Audio for allowing me to review their debut IEM lineup. As a budding reviewer, I really do appreciate the opportunity given. The IEMs will be sent back to Periodic Audio after the review. Because I can only post one review for each item at a time, the same opening paragraphs will be repeated for all three IEMs, with only the review on sound differing.

    A short preamble before the review proper: Periodic Audio takes an interesting approach to their design philosophy. I will not bore you with details here – you can find all you need to know about their company and approach on their very neatly designed website,

    Two things that I found most novel in terms of design and engineering choices, which is reflected in their company name, is firstly, their choice of driver material is based off certain elements on the periodic table. Their opening lineup includes Mg (Magnesium driver), Ti (Titanium driver) and Be (Beryllium driver), which is their current top-of-the-line offering. Beryllium seems to be a popular choice of material for hifi, which I recall the popular Focal Utopia headphones also utilizes.

    Secondly, Dan and team have chosen to use a polycarbonate shell for the IEM housing, which purportedly reduces resonance drastically. I was skeptical at first, but after my initial impressions which I will go into later, I realized that it sounds like they are on to something.

    Packaging and Accessories:

    The packaging comes in a utilitarian white cardboard box, and in it contains the IEMs, as well as a selection of tips including silicone and complys in small Ziploc packs, stuffed inside the yellow gold metal container with the Periodic Audio logo emblazoned on the top shell. They have also generously included an in-flight adapter as well as a 3.5mm to 6.35mm (1/4”) adaptor. Some may raise an issue with the quality of the packaging, but personally I can see that Periodic Audio has chosen to focus on the quality of the product and accessories, which they clearly delivered on.


    All 3 Periodic IEMs sport the same outer shell and housing, with the differentiating factor being the piece that covers the back of the IEM indicating the type of metal used. The Mg has a shinier silver back plate; the Ti has a slightly darker hue, a gunmetal type tint back plate; and the Be being the easiest to spot among the pack, having a darkish golden back plate that is quite aesthetically pleasing. The polycarbonate shell feels tougher and harder than it sounds, and is a deep black. What is also interesting is that there are no L/R indicators on the shells or the strain reliefs, but the guys at Periodic have opted to colour-code the earpiece filters. The left earpiece has a blue filter, and the right has a red filter. The only downside about this is when trying to identify them in an environment that may have little light – it might be difficult to tell the difference then. I had no issues during the day though.

    The housing itself is also a vented design, and the vent can be found at the top of the earpiece.

    My only niggle with the IEM design probably has to be the cable. The cable seems run-of-the-mill, and does not feel sturdy enough to endure daily abuse. It also has some cable memory, tends to get tangled easily and is also not very compliant during coiling and storing.

    Comfort and Seal:

    I found all 3 IEMs to fit well and fit quickly, with very decent levels of isolation when I’m out and about during the day. This is with the default silicone tips. Once they are in, they also do not move about easily, and I find that they sit snugly in my ears. The IEMs can be worn both over ear and on ear, but when worn with the cable dangling downwards I tend to get microphonics. This is largely a non-issue when the cable is worn over ear though.


    Sources used – Onkyo DP-X1A, Sony A15

    Looking at the frequency graph as well as the short description accompanying it on the Ti product page, one would expect the Ti to be aggressive and harshly v-shaped. I am someone who is quite averse to v-shaped signatures. This was exactly what I was expecting and I was very surprised to find that it was not even half as bad as I thought. It was a very clean signature with significant heft in the bass regions, as well as a well extended treble without peaks or sibilance, which is something that I am impressed with, being someone who is acutely sensitive to the treble domains. I would not disagree that it is a v-shaped signature with a clear focus on the two extremes but as a mids lover I found this surprisingly easy to listen to.


    You get a very similar tuning with the Mg but the bass of the Ti is definitely further north of neutral, and gives noticeably more kick than the Mg. It extends well down below, and with songs that have some real sub bass action going on you're really going to feel it. Of course it's not so linear, with a greater emphasis on the mid bass but clearly this is not one of your average and ubiquitous Beats-styled earphones with just bass and little else. The midbass is tuned in such a way that it is heavy, yes, but only insofar as giving you all the texturing and rumble that is conveyed through a slightly more romantic decay, yet without the sense of bloom and muddiness that most other IEMs end up sounding. The turn of pace is just speedy enough to hit the next note before you feel like the bass is dragging you down. What results is a very immersive bass experience with a lot of fine detailing, and what really hit me was how tactile it felt.


    There is great clarity in the mids, and without any bleeding from the Low frequencies what you get is a very clean tonality and good resolution. Vocal lovers might be somewhat disappointed here though, if you are looking for warmth. I noted earlier that the bass is a tad boosted in the mid bass, which does lend itself to some body in the midrange, but its core signature still remains a v-shape. The mids are in no way recessed, mind you, just that it lacks the thickness of note and warmth that characterises more mid centric IEMs. What you get is a very clean tone with great detail, but what some might consider on the dry or analytical side. I would also say that compared with the Mg, the Ti has more detail and resolves midrange notes a little more capably. Instrumental timbre is also reproduced fairly accurately, and has good bite and crunch, especially with electric guitars and synthesised tones.


    The treble is fast, clear and extended. I felt less fatigue than I expected going by the frequency graph of the Ti. The treble is quick footed with lightning fast decays, resulting in a very detailed rendering of cymbal heavy tracks. I could pick out the individual crashes and shimmers that I usually would not pay attention to, and even then I could not detect sibilance or any semblance of harsh peaks that could irritate listeners during longer listening sessions. This speaks highly of the expert tuning of the treble. I particularly enjoyed Snarky Puppy and instrumental jazz on the Ti.


    With the Mg as a baseline reference, the Ti provides a slightly wider stage with increased resolving ability. Imagine facing the semi-circle of the Mg's stage, but having a little more width that extends further left and right, with its ends going slightly behind the ears. It lacks ultimate z-axis detail and depth to sound truly holographic, but is a euphonic tuning nonetheless. Separation is still top notch and reminiscent of the Mg, where individual instruments are clearly delineated in the stereo field. Imaging is again good in its price tier but may not be the best because of how depth is not as well portrayed as width and height.


    Again, the Ti, like the Mg, would pair well with darker/warmer sources. While a cleaner and brighter source might appeal to trebleheads, the majority of listeners may have early onset of fatigue with less synergistic pairings. I picked the Sony A15 over the DP-X1A pairing for a better resultant tonal match. I'm not too sure if the bass levels are heavy enough for bassheads, not being a basshead myself, but I would definitely recommend using the Ti for bass heavy and/or more treble indulgent genres like electronica, metal, and instrumental jazz type music.


    Periodic Audio has served up a potent combination of IEMs suited to different budgets and tastes in its entrance to the audiophile market. One can hardly go wrong with either the Mg, Ti or the Be. For my personal preferences I’d pick the Be any day, because I’m biased toward a musical tuning that has focus on engaging mids and quality bass. But if one is on a budget, the Mg comes with a high recommendation. I find the Ti more of a specialist – if you love rock or metal, or genres that tend more toward a v-shaped tonal profile then the Ti would be perfect. Well done, Dan and team at Periodic Audio!
