This might be a silly question, is there a balanced cable for this headphone? Is that even possible when the jack is only on one side?
cwelton17
Yes but it has to have a balanced plug in it like the t60rp. I don't think these have one
Would these be considered basshead headphones? I am looking for some over the ear close/semi closed headsphones with a similar sound signature as my AKG K181DJ. Thx.
you can get these on Amazon for the same price?
ashnig
And faster, but Amazon doesn’t bundle in the Slappa hard case. Some people prioritize shipping speed, to the point where they’ll pay an annual $110 fee for a year of expedited shipping (or whatever Prime costs now), while others aren’t too hurried and like some other bonus (like a lower price, or in this case a ... case). Also, keep in mind the Amazon price reflects a sale from RMAF, which ends today (and then the price will go back up).
Anyone compare these to Argons?

Argons are for mid lovers while Blue is for bass lovers Pop music,gaming,movie watching is prbly more enjoyable on Blue while audiophile music is nice on Argon
TheBlueDuck
I haven’t tried the Argons, but I have a pair of Blues. On Head-Fi, people that have tried both generally say the Blue has more bass and treble extension. It makes sense to me that others would say the Argons are mid-centric, by contrast. My Blue has what I would describe as a smooth, warm tilt, but the treble presence is only a little bit more than the mids and overall a pleasantly fun U-Shaped frequency response.
We apologize for those of you that did not receive cases with your headphones with the latest drop. Our shipping team dropped the ball on this and we apologize. We are shipping today.

Were they sent out?

Apparently, yes. He said they were “shipping today” when he made his post.
2 questions -can my aune x7s power these -What's the difference(sound deference) with the regular and dekoni blue t50rp
Basdas
X7S should be able to drive these well Stock t50rp supposedly sounds hot on the treble and not enough bass. Blue supposedly fixes that
Are zoomers designing headphones now?

As of now, these headphone are available on Dekoni website for the same price (until Oct. 31 https://dekoniaudio.com/) and on Amazon with prime free one-day shipping (who knows how long https://www.amazon.com/dp/B07BWJ976T?tag=amz-mkt-chr-us-20&ascsubtag=1ba00-01000-org00-win70-other-nomod-us000-pcomp-feature-scomp-wm-5&ref=aa_scomp.) Kinda undermines the whole point of Massdrop if the group buy doesn't net an improved price point.

I don't riceive the slappa case....
daniele1976
Still? Dekoni sent a message in the discussion here that there was an issue with the shipper, and they sent out the cases.
How much sound does this leak? Any? I would be using these in a collaborative open office sitting close to people. I'm not familiar with how semi opens leak. Thanks
beagleband
The pads seal really well. I think you will be very happy with the isolation it provides. Just keep in mind you need an amp to drive these (Planar Magnetic needs a lot of power to kick).
beagleband
The pads seal well, but the headphone itself is semi-open. It won’t leak much though, less than an earbud. Very quiet. I’d say certainly it won’t leak enough to disturb in an open office environment where people will be typing, talking, rustling papers and pens, but someone literally right next to you would know something was playing if they listened for it.
Would you prefer the Fostex planars from Massdrop, or the HiFiMan’s planars? Go!

After consistently hearing that these where “dark”, I opted for the Hi-Fimans’ which are built like tanks. Someone else would be better qualified to describe the Dekonis
I don’t know if the Blue has been out for a year yet, but I have one. I have a cat, but I store my headphones in an office she’s not allowed in. I haven’t dropped it, but I have taken my Blue with me in a bag stacked with other headphones to a headphone meet, and I’ve also taken it through an airport stored bare inside my backpack with clothes and a few chargers for my electronic devices, no durability issues so far. Everything seems pretty robust, so I wouldn’t worry about falls from a desk or seated height, but I would disconnect the headphone cable when packing bare in a bag. That said... this drop would have come with a Slappa case, so that helps with longevity. I would say the Blue has “big” bass, but they are not Sony XB500 bass cannons! There is enough treble and mids presence that I would disagree with descriptions calling it “dark,” but it does have some midbass warmth and mids body. The treble has some sparkle and decent extension to higher treble range too, but it’s on the safe side of the “hot” knife edge, whereas MY opinion is that the AKG K712 Pro and HD 800 sit right on that knife edge (where good amp synergy makes all the difference between enjoyment and fatigue), and a Beyerdynamic DT 880 is for treble enthusiasts only (it made my ears ring occasionally, sadly). I haven’t heard the new HiFiman’s which are on Massdrop. The HE-400 I heard at home sounded really weird without proper amplification (despite sensitivity, sometimes lead vocals would have the presence of background vocals) and had a fascinating interaction with any solid objects (like my hands) within 1 foot of the earcups. I’ve borrowed an HE-560 (which I thought was a bit dull), and been to trade shows to hear the Edition X and HE 1000 (I quite liked these! But I could hear a sample variation). For the price, I’d get a Blue, but with more budget I’d get the more than 2x as expensive Edition XX coming soon. I’m happy that I have a Blue.
Got a review of these since there are not too many out there.
TLDR, These are a great 2nd pair of headphones, especially to compliment a neutral/bright dynamic. It is likely too dark to be a primary set unless you are really into that.
The Dekoni Blue are a quite dark, v shaped headphone. The bass is very strong and well extended, especially when compared to a stock T50rp that lacks a lot of extension. The t50RP is known for its wonderful mids and they are still on display here, just at a lower volume than the bass. For many this will be a positive as they might find T50RP mids too sharp in its stock form. This is a well done version of the V, vocal maintain their central presence but sounded quieter than usual.
I came away pretty impressed with its performance with female vocals, they sound really good. Its unusual to get a super bassy headphone that does female vocals well, so this was very impressive. They have a nice bit of sparkle to them without being painful to listen to.
There is a nice amount of energy in the lower treble that makes violins sound quite nice, something most dark headphones dont manage to do. These are not overly sibilant, they reveal sibilant but dont add to it. There can occasionally be an edge to the treble thanks to its still having energy in the 10k region but I personally think this is needed to keep them from sounding much too dark.
The Bass is really interesting on these, its bloated but manages to stay fairly well controlled with a good amplifier. It kind of sounds like its a cacoon that is wrapping itself around the other frequences is the best way I can described it. Its always the loudest most present sound, but it sounds like its farther away from you than the other frequences which keeps it from totally drowning them out. It goes very deep and gives this a very fun sound. It has a pretty quick decay thanks to the planar drivers. Thanks to its extention it has some good slam to it.
However I think the bass being so strong does shift the tonality towards being on the dark side, and I personally dont like this as a main headphone. I prefer more neutral to even slightly bright as a main headphone making them not suitable for a daily driver IMO.
The sound-staging is very interesting, the hybrid pads are shaped like the TR-X00 earpads rather than the stock 5TOrp pads and they sit on your ear rather than completely over it (at least it my case). This gives it a very unusual sound IMo, as it sounds kind of like a Semi-open on ear. It seems like you are a short hallway filled with bass, and then the ot her sounds are slightly closer to you but quieter. The pads are very soft and I found this headphone to be comfortable after the clamp loosened a bit.
Most reviews I have seen like the velour pads better than the hybrid pads but I have to totally disagree with that. The velour pads make the mid bass drop a bit (which is good IMo as its too much!) but it comes at the cost of both bass and treble extension. Subbass drops a lot, the midrange gets very warm, and the treble is dulled. YOu are left with a overly warmed midrange focused headphone that makes female vocals sound quite dulled and makes for a pretty mediocre experience IMO.
Unfortunately build quality is an issue with these as with the regular stock T50. I bought this from Fostex Japan directly (as I live in Japan) and out of the box my unit suffered from a notable channel imbalance, the right ear was much louder than the left. I sent it to Fostex for repair and after that it worked great. Also amusingly my earpads were also on the headphone backwards out the box.
Keep in mind also if you get the blues, you NEED an amp. A good amp able to put out a solid amount of current, This is true of any planars. Your results will likely be less than stellar if you just plug it into a USB powered amp or a phone. I did all of my listening with the Burson Fun amplifier, great match for these.
Vishmaw
Great, thorough, and unbiased review. Thanks for this!
I'd prefer a drop for the T60RP...
I have the same problem with these that i had with the stock version, there is a buzzing in the left ear with lower frequencies. Aside from that really annoying defect these are incredibly fun and comfy headphones
And one more review on Headfi with a few new impressions from others.....

For all who have been asking here is a FRG for the Dekoni Blue. We recently acquired a certain piece of measurement gear, call it a working legend, and this is the first measurement made. Kudos if you can name the rig used and now owned by Dekoni Audio!
search
And, BTW the impedance is 50 Ohms.....

we would consider it if there is enough interest.
Funny to find out who ended up with Tyll's rig after he hung them up this way. It was known he didn't pass it up to Rafe and or the publication who still run Innerfidelity. At the same time, wouldn't Dekoni have had a rig for measuring all this time? Well have a good time with the rig. Hope this makes your already great pads better!
How would these fair in games?
Sir_Stuey
better than your RGB headphones in any form lol
Mad. Just bought it a week ago from Dekoni's website ...could've saved $30
Hey Folks! I don't know if you've seen it but the Dekoni Blue was featured in the HiFI+ Ultimate Headphone Guide this summer and I wanted to post the review here for you to see. If you are on the fence about the Dekoni Blue, this should turn you on to the best T50 mod out there! Just clock this link to the review. Just make sure you come back here to buy it! lol.
https://dekoniaudio.com/dekoni-blue-featured-in-the-hifi-ultimate-headphone-guide-2018/
question: is there a way to tighten the adjustment post sliders? mine seem a tad loose, it feels like i have to readjust them every time i put them on. (other than that i'm really digging them.)
motod
I don't know what type of screw the dekoni's have, but you should be able to tighten it up by turning the large screw in further.
jgp1212
i tried that, not sure how much it helped though. will try again this week, maybe i didn't tighten it enough. thanks for the response. :)
Mine came torn a bit on the inside of the hybrid cup (which is disappointing considering the main reason for getting these instead of the regular t50rp is the Dekoni earpads) Other than that they sound great on my Schiit stack, practically impossible to drive without it though.

Newest review from headphone guru! http://headphone.guru/dekoni-audio-blue/
The bass response looks pretty strange on the MK3, with the 30hz square wave having phasing problems (the dip), left and right phasing differently, and the response dipping below zero (https://www.innerfidelity.com/images/FostexT50RPMk3.pdf) vs the Mad Dogs (a mod of the TRP50 headphones: https://www.innerfidelity.com/images/MrSpeakersMadDogA.pdf which also have the characteristic Fostex dip but looks way better. Whatever mod MrSpeakers adds is superior to this one at least on paper. Any thoughts on what's missing on this headphone? Is it just inferior pads not letting the bass seal as well?
search
dm94aq7
^^^ that is not the Square Wave graph of the Dekoni Blue, that’s just a standard Fostex MK3. The Mr. Speakers and Dekoni headphones are both mods.
Can you guys update the specs on these to tell us impedance and sensitivity? That matters way more than what's actually listed (copy-pasted below), some of which aren't even specs (e.g. the partnership between Dekoni and Fosted).
  • Dekoni Blue is a partnership with Fostex
  • Semi-open design based on T50RP MKIII
  • Only Fostex-sanctioned T50RP MKIII mod available
  • Limited-edition blue ear cups and flat black slider rails
  • Fostex’s proprietary Regular Phase (RP) planar-magnetic driver (used in T50RP MKIII)
  • Dekoni’s asymmetrical Elite Hybrid ear pads with sheepskin, velour, and memory foam 
  • Detachable 6.6 ft (2 m) cable with ¼ in (6.35 mm) plug
  • Padded headband for extended comfort
  • Tuned and adjusted by Dekoni founder and audio engineer Tal Kocen

Yes, although looking back, I guess I didn't word my summary very well.
devolutionary
Well, again at least you showed the specs, and I agree with you it definitely sounds better with some juice (over what a smartphone can give).
I had the T50RP, they require a butt load of power. I had my Schiit Asgard 2 at 1 o'clock to get great sound out of these.
If you guys are looking or considering a different type of planar-magnetic headphones, then look up GTR, it's $199.99

I know nothing about Advanced or their GT-R, save that the crowdfunding campaign hasn’t reached their goal (60% with a month to go), and that it doesn’t deliver until an estimated November 2018. Also, crowdfunding is not buying a product... it’s a risk, an investment in trust that the company will succeed to deliver. Could it be awesome? I don’t know, but I like to see companies succeed and grow.
The Dekoni Blue, that is a known quantity for me. I have one. Warm, exciting, and fun, this “official mod” has extra bass and “solid” sounding mids but is tastefully fun, a contender against the dynamic driver Philips Fidelio X2 but a complimentary contrast to the AKG K7XX and Sennheiser HD 6XX. It’s an easy recommendation for EDM, trance, hip hop, and pop, really effective at conveying the energy and emotion of tracks without sounding as blurred and slow as cheap bassy headphones. It may lack the ultimate refinement of top of the line headphones 4x the price, but it’s most of the way there and clearly better than typical mainstream products.
Hopefully this provides some idea of the character of the Blue, so people can gauge for themselves if it seems like it suits their taste.
I have a preproduction HD 58X, wish I got to hear the final release version! Reads like a fun open headphone. At this point, I have so many headphones, I might as well go for complete collections, haha.
Just as an FYI since people have been asking and commenting on the cable connector when we designed these that was a big part of the discussion. What I was told is that the issue with the connector cutting in and out is not the jack itself but the coating that was on the cable end. If you take a fine grit sandpaper or even a Brillo pad you can remove the coating and won't have the issue any more. The cables provided with the Blue does NOT have this coating on it. It does not, however, solve the jack itself but Fostex would not change it for us on this run. Maybe if we do something else we can do that.

For anyone who doesn’t know, Tal Kocen is the sound engineer and one of the founders of Dekoni.

If what @Evshrug is true, I appreciate you monitoring this forum, sir. I have all the headphones that I need (1 pair open [for THAT resonant sound stage], 1 pair closed [to prevent disturbing my spouse]). Now, what I *want* is to experience planar magnetic’s (hopeful) base. A wall of sound, as it were. BTW, my HD6xx uses prpprietary plug-ins, so as long as the Fostex wiring resists premature shorting-out, I’m cool with it.
I picked up a pair of MK3’s stock. The included cable locked in and would not release. Left right channels would drop out as well. I removed the cable and threw it away as it is shit like everyone describes. These adaptors fit and work perfect with my Mk3’s: https://www.amazon.com/gp/product/B01NBJW3T5/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1 You can use your own cable of choice with this adaptor as well as flip it up and tuck it into the housing when the cable is removed. This should help save the jack in the long run if the adaptor stays in place.

It does have this problem per the link you have given. Its the locking jack that I found the issue not the coating.
" It does not, however, solve the jack itself but Fostex would not change it for us on this run. "
I was very interested until I realized they kept the T50RP's awful proprietary jack with the same badly-designed locking mechanism. I've had two different variants of the T50RP, the MR Speakers Mad Dog (modded MK2) and the standard MK3, and both work perfectly except for that awful locking mechanism that prevents cables from making proper contact with the headphones. My sound keeps cutting in and out on one side and/or both. This has happened with both sets of headphones after a year or two of careful use. Both fostex's cable and a V-Moda one that's often recommended as an alternative make t he same unreliable connection, so that I'm constantly messing with the cable to get the sound to come out from both sides. I still can't believe Fostex hasn't done away with the stupid thing because this series of headphones sounds fantastic and is built like a brick otherwise. As things stand, I'm unwilling to waste join a drop for yet another pair of headphones that will crap out on me for the same reason.
Is there any possibility we could get a special version of the T50RP (or a similar headphone) for the same price, but without that poorly designed locking mechanism?

He’s the “ko” in Dekoni
That’s a lame excuse. It’s worse than telling you are holding the phone wrongly. ‘Rub the cable!’ That’s what Fostex solution to its customers? That company is seriously wrong. Not willing to change the known issue when confronted by massdrop, that speaks something about the company.
Can it be chosen somehow that the earpads are full leather, not leather and suede? I usually cannot stand suede touching my face. With some exceptions. :)

Eh, more like a cross between t-shirt and velvet. Leather usually is cowhide, like a wallet or jacket. Both leather and suede are animal hides and fully sealed skins, while velour can breathe and let some hot air escape.
Velour is like a bedsheet or shirt, premium pleather is what they use on Bose Quiet Comfort and Beats headphones, sheepskin is soft and pliable like pleather but it’s natural and not as hard as cowhide leather.

Just realized I know the answer to the original question. Yes, there are fully leather pads for the Blue, they are sold separately but show up on Massdrop from time to time.
Save $20 off retail and you have to wait a month...

Reading the reviews and the discussions below, it seems they are not that awesome and there are better products from the same company that cost less with similar performance, also you will need a sepertate amp to really get the full sound out of this product... I would pass on this drop.
On the money value... which is why we are all here This is an ok drop.
HappyNem
I somewhat agree on average. I haven't heard these, but T50RP mods tend to need the right amping to sound their best. Wouldn't it be great that were a comparative analysis of the variuos mods with various amps. It took me over a year to put together Mod House Argon Mk3 (balanced mod) with the MLCX . A big step up from the experience with several other mods/amps.
HappyNem
This drop is fine, it’s 20 off but you get an extra set of velour pads and a case. It’s just the headphones are kinda not so different from stock T50s (imo) so it‘s up to you to decide if you Want to spend 80 more for blue housing, 2 pairs of pads (they’re nice pads), and a carrying case.
Just got them. Definitely aren't Argons, or even Mayflowers. I don't have a stock T50 Mk3 on hand to compare (mine are in another country atm) but sounds about the same from memory. The treble is slightly less sharp, the bass is about the same, and the mid range sounds a bit recessed (definitely not 15db as the fr graph suggests). Wasn't really impressed with these; put em on and just felt "meh".
Also the Fostex locking cables are trash, get some V-Modas or something.
Also that quarter inch to 3.5mm adapter is laughable. Looks and feels janky af.
Also mine was a darker shade of blue than what was in the picture (and I think even under the same lighting conditions mine would still be a few shades darker).
In summary. These are basically just a T50RP MK3s with a baffle upgrade, better pads, and then painted blue. Are they worth 100 more than the T50s (street price wise)? Hard to say, they're quite similar to me and since I already have a T50 these didn't really impress me.
