Dekoni Blue

General Information


Dekoni Audio is proud to announce the partnership with Fostex Japan in releasing the Dekoni Blue Headphone to the US market. Coming in Dekoni’s Signature Blue color with the Dekoni Livery, the Blue is similar to the T50RP MK III in shape but very different in the way it sounds. Utilizing the Fostex Planar Magnetic Drivers and Body, the addition of the Dekoni Hybrid Ear Pads and other proprietary changes makes this headphone a better version of the original by being less fatiguing and smoother all around with an extended bass response.

Dekoni Audio is known for the unsurpassed ear pads it has developed for an array of HiFI Audiophile headphones, and the development of the Dekoni Blue did not go without the addition of a new ear pad to the line-up. The Dekoni Blue comes with a specially designed Hybrid Ear Pad that has the isolation of Sheepskin on the outside, Velour on the face of the ear pad for comfort, and Dekoni’s Fenestrated Sheepskin on the inside of the ear pad for a smooth transition of sound from speaker to ear. Part of the design of the pad is meant to deal with the issue of the original T50RP driver causing fatigue to the listener after a short period of listening, by reducing the high frequency peak common to this headphone in its stock configuration. Other changes have been made internally to extend the bass response while maintaining a solid low end and tight core sound. Already receiving rave reviews, the Dekoni Blue is launching with an extra set of Dekoni Audio Elite Velour Earpads that utilize the Premium Slow rebound, high density memory foam Dekoni is known for.

Pros: bass, comfort
Cons: look goofy, cable
So, after hearing these and buying them at RMAF this year, I sold my DT 1770's, which I loved and had modded to improve the sound. Why did I do that? One main reason: the bass. I enjoy the 1770's and they were my first real audiophile headphone. They are built like tanks, and sound great, but the Dekoni's have the most articulate bass I have ever heard. Do they look as good? No, they are kinda goofy design, but they are lighter, and the pads are super comfortable. Cranking the bass up, it is just so well defined without being muddy or boomy, not that the 1770 is boomy. This just does what the 1770 does sonically a little bit better--not a ton better, but enough that I reach for these over my 1770, so 1770 didn't stick around. I still love Beyer, but these are just legit headphones. I would like a better cable for them, but at $199, I'll buy an aftermarket cable.

Buy them!
Pros: Affordable.
When driven, can provide a good sound.
Decent enough sound, when properly driven.
Cons: Plastic.
another modded T50RP
Bass can be bloaty.
Needs proper driving force behind it.
The Dekoni Blue. It won’t keep you in a blue mood…

From the first rip in Jumpsuit, you are hooked. The depth of bass on Turbo mode through the iFi iDSD micro Black Label will draw you in and throw you down. You feel the thrust of that bass rumble (not shattering like some but controlled) and know the Dekoni Blue means business. This headphone was meant to rock. Straight up business.

The Dekoni Blue and the official mod are the offshoot of the infamous Fostex T50RP, the venerable go-to mod headphone for those on a budget. The T50RP is legendary for its ability to be modified and hold its own against much more expensive headphones. To me, this would be the equivalent of the 70’s muscle car, which is modded to take on the world. I owned a pair of Fostex T40RP Mk2 for a bit of time. I liked its bass presence and performance. I will explain more as to why it has left my stable.

I thank Dekoni for running the Blue tour, and for the inclusion of the Fostex HPA4 BL headphone amp. The two are meant for each other.

The Dekoni Blue has the typical Fostex build quality. That means it is plastic but can take abuse as many Fostex headphones make their way into the DJ realm. With a sturdy, but not much padding band, it can bend a good bit so one need not worry about that aspect. Pads are held on by small pleather lips, which slide into narrow slits on the headphone itself. From my past experience with the T40RP mk2, I found that to be a pain. So after one listen with the all-velour, I switched back to the hybrid pad and left them there.

With a detachable cable that is fairly sturdy, you need not worry about it being Focal Elear constrictor-weight. With a good weight and feel, it is about right. A nice locking mechanism keeps it on, and you cannot mess that up.

The blue plastic housings are BLUE. Sky blue almost and not bad to look at. They are different than the Fostex phones, as they should be. Nothing too obtuse, or divisive. Overall a decent looking headphone, that will draw a bit of attention to itself, maybe even a query from those in the know, much the way another modifier of the Fostex brand would. Not a bad thing, really.

With no microphonics whatsoever on the cable, you need not worry about being interrupted by that annoying rub. The only qualm I have regarding the overall finish are the exposed cables coming out of the pads that go into the band. They stick out a bit too much for my comfort.

As for fit, the Blues are comfortable overall, but I did find after about an hour with glasses and an ear ring they became uncomfortable. To the point where I either had to change headphones or take a break. This was one of the main reasons I sold my T40’s, because they became uncomfortable, even with the lighter pressure than some of my other headphones. Take that as you may, since many have espoused the virtues of the Dekoni fit. I would love to try some of the Dekoni pads on my Elear for a cross comparison.

ON-2: better bass control. Deeper reach and more of it. Clearer sound-better detail retrieval. A brighter sound signature as well. Better isolation. Less fatiguing. Fit while good tend to slip. Grip pressure is about right. I had less of a problem with the ON-2, than the Blue.

Grado GH-2 limited ed: more mid forward. Less bass (open back…so). Details on par with ON-2, but less bright. A more “mature” sound, but not as warm as you would think. Vocals are sumptuous. Fit is near ideal as the GH-2 is about as light as a feather. Once music starts, forget about it, except for isolation, which is all but non-existent. I can clearly hear me pecking on the keys. Bass is solid, but no rumble. Simply put, it is there and clear. Heavy cable, which detracts from an otherwise stellar product. Plus, the cable is not detachable. Not a deal breaker to me.

Further detail:

Sometimes I peruse all that is written about a product before it arrives. Other times, I don’t. This would be a case of the latter, since I had experience with the T40, and had previously read extensively about the T50 mods. I will admit it was quite fascinating what some had achieved, and I liken the T50 mods to modifying a 70’s American muscle car, whether it be Mustang, Camaro, or Challenger. All have their benefits and some darn fine (and fast!!!) cars have been the result.

So, in that light I did anticipate what Dekoni had done as I heard very good things about the pads they produce as after-market for a variety of headphones. If they could do that to a headphone, then it would be a winner and compete comfortably with the other modded Fostex iterations. So, not having experience other than an ill-fated T20rp mk2 purchase I made as well as the new T40RP mk2 I purchased new, this would be a strict comparison to what I had on hand already.

Upon receiving, I checked to ensure all was there, and I understood how the critter worked with the included Fostex HPA4BL amp. I also had to dig deep for some interconnects, but that is OK in my book. Once hooked to the QP2R/xCAN combo I lit her up so to speak. Sort of. Not able to draw enough volume, I dragged the Fostex amp out and hooked it into my MBP. That was better. Providing decent power and a good sound, the combo wrought decent enough bass, and clarity, but seemed lacking. I could certainly get the volume high enough, but the sound did not impress me the way I thought.

Switching to my iFi micro iDSD Black Label afforded me more options with which to hook. Immediately (OK, after tuning to the “Turbo” mode) the sound was more vibrant, richer and fuller. Packing up the Fostex, it would remain in the box for the rest of the test. THEN, I hooked back into my QP2R for a quick listen and all was good. I checked the Shanling M3s as well, and my trusty M5 as well as the Opus #2. All was good. That said, the majority of my time was spent on the BL/MBP combo using either Tidal from my playlist or random bits of work, or Pine Player and the new twenty one pilots album, Trench. This album should immediately be brought into everyone’s queue for testing purposes. A more mature brand of TOP, there is still enough reverence for their history to know and understand this is the next logical iteration of their sound. Fabulous it is, and wrought with such variation of sound, that it alone would be worthy of use for a full-on review of any gear at hand. Good stuff.

Once the sorting was done, I noticed how the Dekoni needed a good bit of power to successfully play. This is the first set of cans, which has needed the Turbo setting on my Black Label. While I could use normal, the volume needed was such that distortion came into play if I tried to really drive the Blue. Once on Turbo though, no problem. So, find an amp with enough juice to drive them properly lest you do yourself and the Blue a disservice.

With the BL at slightly less than half volume on Turbo, the sound is deep, rich and near-vibrant. Changing between XBass+ being on or off as well as the 3D+, you could fine tune much the way one would to personalize your critter in hand. With both on, Smithereens sounded light delicate and pronounced. With Tyler’s thumping bass to fill in the sound, you could gain an appreciation for not only the new TOP sound, but for how well the Blue can scale and “adapt” outside of sheer driving rock/metal/edm mode.

Follow that with the melodious Neon Gravestones, and you begin to understand the tuning Tal & company brought forth in the Blue. The T50RP is good, very good for its price. The Blue is excellent. I thoroughly approve of all tuning aspects and find this a good bargain at the $299 price range. On sale for Black Friday at $199, ramps that up to an excellent value. Smoothing out the typical T50RP “harshness” the Blue provides a very good mellow sound, with an authoritative rumble of bass. Especially when you have a bass switch on an amp.

I did find the bass a bit overpowering and boomy, with a lack of control on some songs. When I switched the XBass+ off though, the sound came back under better control. Other times I left the switch on, even with that boomy sound just for giggles. Kind of fun, it was.


Dekoni Blue ($299) vs thinksound ON2 ($130):

The ON2 was a gem I took a flyer on, purchasing a used set. Having not heard it before, I was a bit apprehensive at the purchase. Upon arrival and a listen, that thought quickly left the state of Missouri and is currently floating above the Pacific I believe. As an on-ear, the fit is very different. Made from sustainably-harvested wood, and recycled plastic, I loved the environmental aspect of the ON2. It made sense to me, and I still do not understand why it has not gotten more attention. It is quite good.

Immediately different between the two was how the mids are presented. Mellow tuning would be the verbiage used for the Blue (another departure from the T50RP). Forward would be one way to put the ON2. Bass quantity is definitely present, and a bit better controlled than the Blue. Rumble is present, but not in the quantity of the Blue. I also think due to the mellow nature of the Blue, that detail representation is a bit better in the ON2. This really isn’t a slight against the Blue, just the way it is. That mellow-er sound draws you in, enveloping you and it is good. The almost-bright characteristic of the ON2 is fabulous, and due to its more portable nature as well as isolation would make a wonderful pair to use on the train. I really like the ON2, and for the price an absolute bargain. Two approaches, two different results, neither bad.

Dekoni Blue ($299) vs Focal Listen ($249, blowout for $129):

I will openly admit that my pair of Listen get shoved to the back of the queue too often. Purchased as a comparative tool, I do not bring them out often enough. So as luck would have it, they fit right into this review. If you have been around the planet for the last several years and within the audio world, you know of Focal. First a loudspeaker maker, then branching off into headphones, their Utopia is widely (not without criticism) thought to be one of a handful of the greatest headphones ever produced. Outrageously priced, the sound is of legend. Many purchased a pair simply because…Me? I opted for the more “affordable” option and the Elear. That purchase spurred the purchase of the Listen. In and of itself, the Listen is rather uninspiring. Not really a bass model, nor neutral; it was thought to be Focal’s attempt at drawing the Beat crowd, what with its more affordable price. Relegated now to the wireless version (mine are not), it quickly became the forgotten model. But at that blowout price…another story.

As an overear, the Listen isn’t that comfortable, or versatile. It can fold quite small for portable/commuting use, which is a benefit. Without the XBass+ or 3D+ on, the Listen becomes quite average. With both on, there is good bass, and a clear treble sound. With mids well behind the ON2, it takes a second in that realm. The Blue bests the Listen in the bass department, and other than the transparency of the Listen, pretty much beats it in all categories. Don’t get me wrong, the Listen is still worth a look at the price now, but there are better options.

Dekoni Blue ($299) vs Grado GH-2 Limited Edition ($650):

As part of a TTVJ demo tour, I was lucky enough to audition the GH-2. I liked it so much and appreciated the history behind the brand that I purchased one of Todd’s last pair. I do not regret it at all. Unfortunately, due to my “family” circumstances, using an open-back headphone is not very copacetic with the wife-unit (whom I love very, VERY much). So, other than the odd day alone or review comparison the Grado does not get much love.

The open back belies the bass, which is present. Rich, full and on par with many semi-open and closed-back headphones make the GH-2 a stellar representative of the Grado brand. My review sung of the virtues of the tune. Details galore, as well as a transparency, which allowed the history of Grado to shine through, there is a reason some follow the brand fanatically. A method that works should not be messed with. I will state that there is a bit of an odd sound regarding the mids which some may not find appealing. I like it simply because it ties the treble to it with aplomb. A bit of sparkle leads to a sound, which contradicts the open nature of the headphone. With decent enough bass, and a fit, which makes the GH-2 feel as if they are all but non-existent on your head make for a winning combo in my mind. Even with that silly Anaconda of a cable. This is a good unit but looked at for completely different reasons. I posit the comparison still holds, as some within the Fostex modded department aspire to bring the price into that range. Thankfully, Dekoni did not.

Dekoni Blue ($299) vs Focal Elear ($699ish):

Fashioned as the result of another TTVJ tour, the Elear was my second purchase into the realm of upper-end headphones, after the Grado listed above. I love my Elear and everything about it (except that silly Anaconda cable, which was consequently replaced). I quickly replaced all cables with three sets of LQi cables of the 3.5mm SE, 2.5mm bal and balanced 4-pin XLR variety. It still holds its place in my signature as favorite along with that incredible Apex Pinnacle 2 and the QP2R. Wow, just wow. That said, I believe the comparison is again valid as Dekoni strives to achieve above the level of the T50RP, and based upon all of the comparisons above, it has. Better bass quantity than the Elear it moves ahead. It cannot compete with the detail or clarity of presentation though. It really isn’t meant to, since the price is at least 2x between the two. Where there is better detail retrieval with the Elear, there is better bass in the Blue. Where there is better clarity in the Elear, there is that mesmerizing planar sound. So, you see, the Blue is quite worthy.

What leave us, thee?

So, after all of that non-sensical comparison gibberish above, what are we left with? We are left with a pretty doggone decent headphone. One in which a company took an established model and is trying their hand at raising that to the level of other modifiers. With full blessings I might add. And in that regard, the Blue is worthy of consideration should you be looking. I am one of the few who mentioned the fit issues, so it must just be my silly big head. Take that as you will, but know that if you wear glasses, it may be a compromise you make. And it would be OK in the long run, since the Blue is a pretty darn good iteration of the Fostex T50 RP mk3.

The Dekoni Blue is a wonderful sounding headphone when properly driven. It ticks all the boxes for someone who wants good bass, decent transparency, and a decently-wide soundstage. Under the tutelage of my Black Label, I could make it sing properly and that is a good thing. Well done, Tal & crew.

I thank Tal & Dekoni for sending their product out on such a lengthy tour, we greatly appreciate the opportunity to peruse the product. And as mentioned I have ended up with a couple of very fine products as a result of tours. Not a bad way to spread the wealth.

Disclaimer: I am not endorsed by Dekoni Audio for this review. I did not pay for this product being the nature of a product tour. All I wrote are my honest thoughts on the product.

First off, a big thank you to Dekoni Audio for the opportunity of being a part of the tour. In this tour, I get to demo a pair of the Dekoni Audio Blue for a week along with a Fostex HP-A4BL DAC/amp. This is my first time being a part of a tour for any headphone, so I’m very excited and thankful!

I haven’t actually heard many T50RP mods even with the abundant companies that mod them and guides to mod them. I did work on a mod on a T50RP MKIII but had no idea what I was doing and sold them long before I really got into modding. Other than that, the other T50RP mods I’ve listened to are the MrSpeakers Alpha Dog and ZMF Ori.



So I guess as an "about my preferences", I like a warmer sound signature though I don’t like too much mid-bass emphasis. I do like some emphasis in the sub-bass however. I generally like the 2-5 kHz range to be a bit laid-back - helps vocals and overall timbre to sound more warm and natural (or at least to me). I find emphasis in this area to make vocals sound shouty and unnatural. I really dislike being drilled by any sorts of sharp peaks in the treble. So basically, a bit warm and smooth.


  • Driver: Planar magnetic, same driver used on the T50RP MK3
  • Impedance: 50 ohms
  • Weight: 320 grams
  • Sensitivity: 92 db/mW (more on that below)
  • Frequency Response: 15Hz - 35kHz
  • Maximum Input: 3000 mW
  • Cable: 2m or about 6.5ft, terminated into a 6.3mm/1/4” jack, comes with an adapter for 3.5mm compatible devices
Alright so the sensitivity listed here is 92db/mW at 1kHz with 1mW, that means these have the same identical sensitivity listed on the T50RP MK3. However, the sensitivity should be much lower because of the added distance from the earpads. I would think the sensitivity would be from 87-90db/mW. I would recommend a beefy amp to power these things.

It feels like a T50RP. Actually, there seems to be a bit of heft here in comparison to a stock T50RP. Probably just from the earpads. It has a nice weight to them, and may or may not survive a few drops.

3 - AkkqeE2.jpg



These are semi-open as with the original T50RP MK3 in that only the bottom vents are opened. I believe the T20RP MK3 has both top and bottom vents opened and the T40RP MK3 has no vents. The Blue muffle sounds a bit but you’ll still hear your surroundings. These do leak quite a bit because of the semi-open design.


Fit & Finish:

These are, of course, infinitely more comfortable than a stock T50RP with its thick earpads. The surface that actually touches the side of your head is a type of velour (with the provided angled hybrid and “flat” earpads). The headband seems to have a bit of cushion which I don’t remember being on the stock T50RP - it has been a while since I last owned a T50RP, so I don’t remember if it’s the same headband. It does develop a bit of a hotspot on the top of my head. They don’t feel too heavy on my head and the earpads are very comfortable. Clamping force is light but adequate for a good seal which is probably helped immensely by the thick earpads.

The headband yoke is now coated black which I find to be a handsome and welcomed change. The earcups are now blue as the name of the model would imply - it’s like a “70s diner” kind of blue; I like it.

For the majority of this review, I used the provided Fostex HP-A4BL for no EQ and my Gustard H10 for EQ (as it can push more power when I lower the pre-amp). I primarily used the “flat” velour Dekoni pads provided with no EQ.

Unfortunately, I’m going to sound very critical from here on out.

First Impressions (same with both pads):
  • Midrange is very recessed and overall sound is uneven
  • Bass doesn’t extend well into the sub-bass, rumbles are non-existent
  • Bass is very boomy but doesn’t have much “weight” to them
  • Treble is fairly bright and gets fatiguing after a short while
  • Not very detailed nor clear throughout. Muffled sounding
  • Overall, unnatural sounding.
Now, my thoughts are more or less the same.

7 - mDfMbiA.jpg


The bass here is very odd. These do not extend low very well. I do not hear/feel any rumbling or feel the “weight” or impact of each note - as some sort of reference, I find adequate “weight” or “body” with a linear or slightly raised response going from 100-20 Hz. On the contrary, these have a BIG mid-bass emphasis that creeps up into the midrange. What’s odd to me is that it sounds very bloated andthin at the same time. It’s weird, I know. The overall response of the bass is uneven which I find makes acoustic drums sound unnatural. It kinda works for EDM with the mid-bass bump but again, don’t expect any rumbling or a good ‘hearty’ bass.

Overall, I don’t like the bass response. It sounds bloated and is not well-rounded. I am led to believe that these were not damped incredibly well or at all.


The midrange sounds very recessed. This is partly due to the big mid-bass hump and also, I believe, from added distance given by the thick earpads. Guitars and vocals sound very distant and congested. The response here is not very detailed nor resolving - most likely masked by the heightened bass and treble response.

Overall, I don’t like the midrange response relative to the bass and treble response. Vocals are muffled and details that fall within this range are either masked or blurred.


The response here is elevated and fairly harsh. The headphones are fairly bright, and it does get fatiguing over a short period of time. It is very unforgiving, so poorly recorded/mastered tracks will sound unpleasant here. The sense of immediate detail here seems good with its heightened treble response. However, it’s not a very pleasing response as it sounds way too bright and fatiguing.

Overall, I can’t say I like the treble response here. It does not compliment the midrange well, is sibilant and harsh, and isn’t very pleasing.


These don’t sound particularly wide. Instrument separation is ok for the most part - I say for the most part because the mid-bass bloat seems to congest and blur the localization of instruments a bit. On that note, imaging is just ok.

I illustrated what the soundstage would “look like” below:

Dekoni Audio Blue soundstage comparison - Imgur.jpg

Pad differences:

Simply put, the angled hybrid pads give a brighter tone. Vocals are a bit more forward on the angled hybrid pads. Otherwise, there were no sonic differences that I noticed.

I actually have stock T50RP MK3 pads on hand, and uhh.. I like the sound with these more.. It’s a lot more balanced. Measurements in the link below.

These don’t take EQ particularly well. I’m getting audible distortion bumping up the lower registers (<30 Hz) even while lowering the pre-amp - I think this may be the driver reaching its limits. The midrange and treble are just screwy.

It still doesn’t sound very good but here’s my EQ as of writing this:

Pre-amp: -8db
  • 30 Hz: +4 db, Q: 1, peak filter
  • 50 Hz: +4 db, low-shelf filter
  • 70 Hz: +2 db, low-shelf filter
  • 115 Hz: -5 db, Q: 1.5, peak filter
  • 300 Hz: -8 db, low-shelf filter
  • 375 Hz: -4 db, Q: 1.5, peak filter
  • 700 Hz: +4 db, low-shelf filter
  • 2000 Hz: +2 db, Q: 1, peak filter
  • 2750 Hz: -4 db, Q: 2.5, peak filter
  • 3000 Hz: -6 db, high shelf filter
  • 4000 Hz: -4 db, high shelf filter
  • 4400 Hz: -3 db, Q: 4.32, peak filter
Alright some of the settings seem counter-intuitive or redundant but that’s just what I got. Measurements in the link above, at the bottom of the album.

I keep the pre-amp fairly low since I have a couple songs that still manage to peak the clipping meter.



To sum up, I did not like the Dekoni Audio Blue. The odd bass response, recessed midrange, and the harsh treble all add up to an unpleasant listening experience. It is not very resolving nor detailed overall - everything just sounds blurred and congested. At the price of 199 USD new, I am disappointed to say that I cannot recommend these. There are competitors that are better below or at that price point. It seems these headphones are marketed to those who wanna dip their toes in planar magnetic headphones, but I’d recommend an HE-400i or HE-4XX for that. Hell, those cost less than the Blue right now! I daresay that I like a stock T50RP MK3 more than the Dekoni Audio Blue, comfort aside.

As for a suggestion, I would like the mid-bass to be dampened and have better extension, the midrange ironed out (for a less jagged response), and the treble to be smoothed out. I think the frequency response will be better with thinner earpads. These definitely need a re-tuning. The modder in me really wants to take a crack at it but this is just a demo unit so I can’t :wink:

Please let me know if I made any grammatical errors!

A fair assessment and well laid out review, thank you!
We appreciate your review, & your participation in the tour. Even if we didn’t get to thrill you & earn an instant recommendation, it does give the community a data point to consider and hopefully someone seeking a flat neutral response won’t try these and be disappointed, while someone desiring a warm and full bodied sound may still enjoy what they find in this.
Great honest review, straight to the point with science to back up your impressions.
Wish more reviews were like this (RIP innerfidelity)


Big congrats and kudos to Dekoni for a superb job on these. After listening to the Blue at CanJam NYC 2018, I made a mental note to buy once they became available. Bottom line for me: These are, without a doubt, the best T50RP modding effort ever. And I've owned or tried many over the years. I don't know what you guys did (and perhaps it was very simple and basic) but you succeeded.
