HiFiMan Sundara Closed Back Review part 2 + Give away. Frequency plots and sound comparison

[@Burnt_Water]

I'd love those cans! *insert story here about how my life is terrible due to losing my job/pets/house/relatives (pick your favourite) and everything would be fixed if I got some fancy gold headphones for free* But seriously, those Sundaras look awesome. I haven't tried any planars before and I want to hear whatever it is that apparently makes planars so good. Been running with my AKG K371s for a couple years and I love them but I'd also love to be able to switch it up a bit without creating a sinkhole in my wallet :p

[@CustomCans]

My hobbies are Cars, Headphones and computers.. My wallet is more sinkhole than wallet now... I feel your pain. Good luck

Never tried a hifi closed back nor planar headphones but I would love to ! The cable also makes the set look quite exciting. Loving the stuff you guys doing !

Thanks ;)

Greetings from Canada! I just recently discovered your channel as I’ve been researching my next acquisition and I’m quite interested in trying some planers. I really enjoy your deconstruction process you have great insight and curiosity about the whichness of why on how these phones all sound. Thanks! I’d really enjoy these and most importantly, I just realized my wife has caught up with me in number of headphones, which will never do! Lol. All joking aside thanks for putting your videos out. I really enjoy them. Cheers

I'm new to audio world so this is super interesting. Looks like a good reason to learn about EQ and experiment with the tuning. Also super interested and appreciate when the headphone has that personal touch from another person's craftsmanship

[@Scroggler]

A new pair of headphones is ALWAYS needed! I'm interested to see what the experience is like as someone who's only used Beyer cans. Also, a video going over cable braiding would be sick - I'm looking at modding my 770s to take a mini xlr connection and making some custom braided cables, but I've no idea how different braids affect cable length...

[@isothymos]

I dove head first into the audiophile/headphone world and I've been really enjoying your modding projects. You are The Shoe Surgeon of headphones. The Headphone Surgeon! Thanks for the early review, I have been considering purchasing the open-back Sundara for quite some time (for studio/piano/general listening purposes). The closed-back version could be more suited for the loud city environment I am living in, but I am going to ponder on the graphs and your comments a little more. Cheers!

[@CustomCans]

Yes, it is a difficult choice

I would definitely love to get my hands on them. I haven't tried to modify planers yet so love to try that, also to see if i could flatten out that uneven graph a bit. So far i have mostly been messing about with various Grado headphones and the Creative labs Cal SE's which are a brilliant headphone for the price. I really is a different experience listening to something you have had a hand in making, there is a certain pride in it. Also thanks for the tips on modifying headphones I've gotten from you for the past year or so.

I've been teetering on getting a pair of enthusiast headphones for years now. Would definitely listen to more music, even more often. My life has been on the up and up, and the past 6 months of my life has been a breath of fresh air. Finally have a job where I have some comfort and sustainability. Recently found your vids after doing more research on headphones. Definitely here to stay.

An interesting review. Thankyou.. I have a pair of DT1990, but I found that they are not the best when used in a hospital bed. Too many requests... I was contemplating a pair of DT1770 or DT177x to resolve the issue, but now I have the Closed-Back Sundara's to consider as well. Well done with the custom artwork. The results would look good in pride of place in my loungeroom... I look forward to seeing future projects....

[@CustomCans]

I am pretty certain the 1990 and 1770 have the same driver - if you are feeling brave, you could open up the 1990 and plug up all the holes on the inside with plasticine or something and pretty much end up with some 1770s

would be very cool to get them of course. Really have been loving your videos especially the modding stuff since I really love tinkering with stuff and modding my headphones if i can to try to improve them since it's really a pleasure. That clip in waveguide mod on the he400se that you haven't released made me make my own for my pair of OG he400 s i had found, works wonders. Your really the only person making modding videos on headphones on youtube and either im looking at the wrong places but I'm surprised that this part of the hobbby is a smaller than i expected. But maybe thats just cause coming from the switch and keyboard modding scene n that I've got the wrong expectations. Regardless, keep up the awesome content. Thanks jason

[@rh-hereforthemusic511]

Hi Jason, thanks for your work in sharing your knowledge of how all these cans work... ok, let the hustle begin!... My cousin's friend kindly gave me an Ableton Live controller after I he had asked me for help with something. He needed to re-record some dialogue from a TV show for a track he was making, as it was obviously unrealistic to get sample clearance(!) He asked me, and I did it earlier this year. It was a cool process, just to be a small part of. Now I have not only ticked off a bucket list item, but also started down the path of music production. I don't currently have any headphones to work at this kind of high fidelity standard. If i'd be lucky enough to get a pair, I think I would get a lot of fun using them to get into a momentum of creating music, as well as just listening for enjoyment of course. I mean i'm not superstitious, but they say good things come in threes. Thinking about it, the controller, along with - not a monophone but rather - a pair of headphones.... 1+2=3. You will be bringing order to the universe, yes! Finally, not to "kitchen sink it" but..... my best friend is called Jason (seriously), and not shy to provide literal documentary evidence of this... that is of course, assuming you are interested to dabble with... nepotism I guess? Cheers!

[@jaimefernandes6811]

I rather recently got into the audio space and even more recently found your channel with a video on the HD660S as I wanted to see how it compared to the HD600 internally and you seem to be one of the few channels who focus on this type of content. The first thing I knew after getting into things is that I needed to upgrade from my Razer Krakens but being new I had little knowledge at the time so I went on a mad youtube and forum research spree for months until I had learnt enough to find myself making the decision to sell all my unused valuables and buy myself an open back Sundara. The day after they were ordered the closed backs were announced but I didn't mind as I learned that open backs provide alot of benefits which I valued over isolation at the time. I ended up not being able to afford the jds labs atom stack to pair these with due to money issues, so for now I'm running them off of motherboard audio which is a noticeable inconvenience but for now I don't mind too much as these still are the best sounding transducer I have ever heard. The higher efficiency of the closed back would have been convenient for me, along with the isolation given I live in an 11 person household, so if these were the same price and had existed at the time I may have gotten the closed pair instead but I got a bit unlucky. I'm contempt not doing anything for now as I have no way of getting the funding to do so, so I just mentally gave up on the idea and am settling for this until I can get the funding, which I plan to do whenever the opportunity arises. But, if I did get these, I wouldn't keep it as having both Sundaras is rather wasteful. I would just enjoy it for a few weeks or so then give it to my friend who owns nothing apart from the infamous m50x and recently I shipped down a Moondrop Chu iem for him which is still a technical performance improvement over the m50x for $20 according to him. He would benefit from these way more than me with his situation being him wanting a wide stage closed back that does not need amplification, and is fine with using EQ so the tonality issues on this would be solved. It is very inconvenient having no amplification being in a noisy household but that inconvenience is not comparable to having only a m50x and being aware that audio gets so much better even without raising the price. Your channel is really helpful in learning more about this hobby and I will continue to watch it either for passing entertainment or for learning about headphones I am interested in myself. Hope you find larger growth in your immediate future as this channel to me is better than a lot of the larger ones. Regardless of who win, you are a great person for helping any random single person have a new brilliant headphone for free especially considering that at the size that you are, this isn't paying for itself in promotion like with the larger channels' giveaways who do them purely as a business decision and typically have a sponsorship with another company so they they aren't paying for it themselves.

I certainly would love to win these Sundara closed back. I have the open backs, the more recent revision, and just bought an amplifier that really scales them. First thing that caught my eye with your headphones is that you put a Mexica (Aztec) Sun Stone decal on them. As a Mexican, I say to you: nice touch! The other day I tried using the Sundaras as monitors whilst playing with my band. I kept telling the guitar player: louder mate, louder! I couldn’t hear the click or midi tracks. Eventually, the vocalist takes them off my head, puts them on, has the guitarist play back the midi and he literally fell on his bum. He looks at me and says: these sound great, but put on your iems and get to playing, not time to listen to music. Thanks for your videos and reviews. Have a good one, cheers!

[@CustomCans]

Yes, the closed back would be much better for monitoring ;)

I want em mostly because the Sundara was my long time love and I finally got my hands on them, but unfortunately couldn't hold on to them for long because I didn't have a good enough amp.

Here is a funny story for you, I got into this audio hobby a while ago, I'm 23 now but I want to say I started at about 13 years old with very cheap headphones, and IEM, anyways, I decided to finally get a nice pair of headphones, so I decided to go for the HD25-ii-1, and after months of saving I finally got them, I was of course blown away but my parents where extremely doubtful and non approving of me spending months of savings on a pair of headphones, and after I tried to convince them my dad said he wanted to listen what it was all about, but that same day my right speaker stoped working after just a few days of use, of course I felt like crying lol, so I went into KZbin and found one of your videos about fixing the lose connection, which saved me from being totally schooled by my parents, he loved the sound at the end, keep up the amazing work!

[@CustomCans]

The HD25 do give good bang for the buck. Good luck

I love that the only requirement for the giveaway is a positive comment, preferably something that makes you laugh. Well, I've got a story to tell. Back in the day, one of my friends purchased a Audio Technica AD900, this was back around 2007 when PC enthusiasts were using soundcards because external dacs/amps had issues with PC's and motherboard audio was horrendous back then even for low impedance headphones. This friend of mine back then would buy one soundcard after another. He tried the Audigy, then X-Fi, then the Auzen X-fi Prelude (which was one of the best options back then), and another company that was popular back then (I forgot what it was called) and every time he kept saying he doesn't hear a difference! And the AD900's suck! Well by today's standards there are better options, but back then they were a massive upgrade over your usual gaming headphones. Anyway. I ended up visiting his place just to see that the entire time he was plugging the headphones into the front IO of his PC case, even though he was buying and changing soundcards 🤣😂🤣

[@CustomCans]

Lol... I used to be a PC technician in the olden days so came accross that kind of thing a lot. My favourite one was when a customer rang up and complained that the cup holder kept going back in by it's self and spilling drinks... 10 mins later we established that it was a CD ROM drive and not a cup holder

[@HeadphoneHangover]

@@CustomCans oh my God 😂😂 I done a bit of technician work towards the end of high school in the mid-2000's too but never came across that one. Cup holder lol

[@surreptitiousscreamer]

@@CustomCans haha, I have had the same job and seen the same thing! I also had a Doctor who paid £380 on a callout because they couldn't find the off button, which was right on the front with on/off written above it. I also had a man who covered his monitor in tin foil to stop the demons getting out. When you deal with the public, stories are often made.

[@killerra]

Great review, you are better at describing sound than you give yourself credit. I've been using the OPPO PM-3 for 6 years now as my portable closed back, the leather looks like it's gotten in a fight with a wolverine, she's beyond ready for retirement haha. I'd give it away but the receiver would have to be as good as you at refurbishing/modding headphones. It does hold a special place in my heart though, being the first closed-back planar ever, and it's now discontinued. I'll put it in my museum if nothing else.

[@CustomCans]

If you can hold on until around march, we could probably book them in for a refurb

[@killerra]

@@CustomCans I'll keep that in mind for sure.

[@AndrewLamas19]

I’ve been thinking about getting the Sundaras and this looks like a great chance to try and get some high quality headphones for FREE‼️

[@CustomCans]

Good luck in the comp

[@AstrumPuella]

Hearing you say that you're going to be ripping out the tuning, to see what does what, makes you sound like a mad scientist. "I wonder what this bit does?" and then you rip it out, potentially permanently damaging them, just to see how it changes the sound. Love the content, and yeah I want em.

[@CustomCans]

The best way to learn is always to break something and then figure out how to fix it...

[@BL4STTH3F411]

Mods seems fun, been interested to start my own modding since i bought a modded dt880 from the used market. but the fear of ruining the headphone is holding me back. I hope to complete a headphone mod of my own one day. Cheers anyway your videos are great.

[@CustomCans]

Yes - it is a bit scary the first time. Even though my team and I have a lot of experience, we still break things some times

[@jopar3292]

Thanks for the video. Of course I would love the Headphone! looks beautiful. I was lucky recently to find a very cheap original HE400 - they sounded good BUT I had an old 1990's Sharwood amp from years ago that Ive never used as I tend to use IEMs, and plugged my DAP into it. Honestly I could not believe how much of a difference it made. Like a mid tier to top tier sound difference. Point being planars enjoy a good amount of power which Im sure we all know here :) but more importantly, (If I may be so bold as to plead with ya'al) where ever possible always seek different synergys with your signal flows - It only takes one [less-than-perfect component in your audio chain to knacker the end sound! ;) Its amazed me over the years how sometimes there is a gem hidden inside headphones that sometimes need a bit of time to get to - different source, pads, cables etc etc (Ive heard of this company called 'Bustin Mams'? Something like that? who do superb cables...maybe you heard of them? - should be easy enough to find )

[@CustomCans]

Yes .. they do need a good chunk of power to get the best out of them

[@jopar3292]

@@CustomCans It never ceases to impress me the amount of incredible quality that came out of the 1990's - Sennhesier HD 540 / HD 250. Beyerdynamic DT 880 600ohm - even the 1980's Beyer DT770 is WAY better than the modern versions - much more natural and linear AKG Sextett etc etc

[@itsmebrandini]

Would love to win a pair and try them out myself, but just glad to see what you have to say and appreciate you sharing your thoughts :)

[@CustomCans]

Thanks

[@BigKev.]

Didn't expect all the gold design but it's definitely groovy.

[@CustomCans]

thanks ;)

[@peterbellamy4272]

GOLD! - Always believe in your soul. You've got the power to know. You're indestructible! Always believe in, 'cos you are GOLD! I would like these very much.

[@CustomCans]

Now that is going to be stuck in my head all evening ;)

[@kazumasatou6124]

Really interested to get one of these! I'm currently appaled by hifiman qc on my edition xs when the unit I got had rattle on the right side. Even before the rattle, I felt like the advertised "bass" was not really there; even the sundara open back new revision had more bass impact. I hope these sundara closed edition will scratch the itch of the basshead junkie I am!

[@CustomCans]

I am sure they would .... Good luck

[@DanAndreiVladut]

Hi man, I've followed some of your he400 se mod videos, but didn't subscribe until now. I'd love to win these headphones. I loved the Sundara when I had a pair, but I sold them looking for something closed back. Haven't pulled the trigger on anything, but having a closed back Sundara to keep the dementors away while listening would be phenomenal. Also, they look trés chique, certain to impress my coworkers. 😉

[@CustomCans]

Welcome aboard and good luck in the comp

[@gdemirjian]

Your artwork on the Sundara Closed is very classy, and the cables are The Chefs Kiss! I would love to show them off around the city (Philadelphia)! Love your designs! One LOVE! Cheers!!

[@CustomCans]

Philidelphia... I suspect that ... On the playground was where you spent most of your days. Chillin' out, maxin', relaxin', all cool And all shootin' some b-ball outside of the school

[@gdemirjian]

@@CustomCans yup, but no smacking the comedian at the awards banquet... lol.

[@meowsers2119]

I just want the headphones mate, I've been looking for a decent pair of closed backs and since these have decent isolation I wouldn't mind a pair. Doubt I'd take em to school or anything but I'd use em out and about, plus the cable is really nice so 🤷‍♂️ Cheers!

[@CustomCans]

Thanks ... Good luck

[@khiempham7520]

I just love watching people messing w electronic lol because i wouldnt dare diy it myself(for now XD). The thought of being able to change termination in headphone wouldn't even cross my mind until i watch your video man. great job keep it up, in the future can we expect some more model being modded? would love to see something like the Hifiman edition XS or ATH R70x

[@CustomCans]

Glad you are enjoying it ;)

[@andresmp9988]

Trying to increase my listening quality, I bought the open back Sundara a month ago and I'm blown away by the detail. I'd love the closed backs to complement the bass, have another great reference, and record vocals on my little-more-or-less-homestudio! Haha. Good luck everyone!!

[@CustomCans]

Good luck

[@mfonseca]

Those cans would look great beside my DT1770 which was also modded by Custom Cans! 😊

[@CustomCans]

Ahhh... a collector ;) ... Good luck

[@neurotikk777]

Hi Jason! To be honest I just want to take part on the giveaway to get your new cable (from your last video) for my focal clear :D

[@CustomCans]

Well.... Luckily the hifiman and focals both take the same kind of connection .... Good luck ;)

[@louislfl51]

I'm currently working in a radio station... it would be fun to go to work and here in the back "Wait!! Where did you find these??" - "Custom Cans of course" I wish I could win them!!

[@CustomCans]

I did a brief stint on the radio - it is harder then I had thought .... Good luck ;)

[@Raiinmaker77]

Huge fan of Custom Cans, loved my modded DT990 from you! Interested to try the closed back Sundara as I never fully got the hype behind the open backs and wonder how these compare!

[@CustomCans]

They would be a good pairing as they are very different, I suspect you would hear totally different things swapping between 990s and these... good luck

[@ACAB-qz9zg]

I Would very much like the headphones because !! Seriously though, I have ears, so these are literally designed for me!

[@CustomCans]

LOLz :) They are designed speciffically for people with ears

[@exactom6320]

I'm a noob to the hobby and google decided I might like your channel. I'll be honest I don't understand most of what you're going on about but I'm interested to learn and a pair of shiny custom cans could be just the thing to send me all the way down what's looking to be a very deep rabbit hole...

[@CustomCans]

Lol.. It is a deep rabbit hole ... Good luck

[@edbyrne1740]

I would love a pair of these what’s not to like it’s HIFI bling! My portable amp & play combo will drive these extremely well so therefore they would be excellent on the go not walking through the streets or in the car though with them on obviously I will wait until I get to my chosen location first haha!

[@CustomCans]

Nothing wrong with a bit of hi-fi bling ;)

[@MrVontuuba]

Thank you for your all around excellent content. While doing my daily walks I always feel under dressed for the occasion with my my plain old stock headphones and cables. Could really use those blazing Sundaras and that balling cable to level up my outdoors appearance. Pretty sure those would also have the benefit of motivating me to do even longer walks leading to a healthier life style longer life expectancy. That would benefit you as well. Having me around for decades could possibly result in over a hundred video views on KZbin.

[@CustomCans]

Lol - yes - the longer I can get my subscribers to live, the better ;)

[@matfax]

I have used Audeze's Penrose for over a year. They're also closed planars but with an integrated DAC. Even the input jack is reprocessed by it. As a newbie to planar headphones, they've impressed me with their detailed upper mids. I consider replacing them though because of their internal DAC and the uncomfortable headband, despite their low weight. I'm curious what thoughts went into the two different headband approaches of HiFiMan. So if the giveaway is still open, I certainly would appreciate the chance. Great job with these golden ones btw.

[@CustomCans]

I think you are just in time - we should be choosing comments today ;)

[@cversion7]

No sob story. I'd be super excited to jam out with them!

[@CustomCans]

Good luck

[@Stravideo]

Ouuuu Shiny !!! now I can say I have golden ears, Fancy ! Bright as the sun, those would be called closed back Goldara. Please keep doing what you do, that's very entertaining

[@CustomCans]

Thanks ;)

[@Panda34575]

If there was ever a "first time" closed back pair of headphones i could get, this would be an awesome addition to my collection. Would love to compare these to my open backs that I think have good bass (HarmonicDyne Zeus and LCD-X 2021) good luck everyone else.

[@CustomCans]

Good luck!
