Superlux HD 681 and HD 668B Headphone Review

Full Story Here: www.innerfideli...

[@fabiolopes5700]

I'm a huge sound and music fun, I've owned a couple of expensive brand phones and reluctantly, for being cheap, I decided to give them a go, based on hundreds of positive reviews especially from enthusiasts, and man.... The best bet ever, I started with the hd 681 standard version, then I got the 668b and now I own my brand favorite until now the 681F variant. The F version is amazingly perfect. My gear for music is Creative Titanium cardboard , a valve tube preamp, and a mixer. They do require equalizing, If you intend to hook them on portables, or poor sound source they'll sound thin.. Forget about the expensive brands. Superlux can deliver and outperform most of them at a 1/4 or less of their price tag. If you're still wondering whether give these babes a try, go for it...

[@CT37BN]

Got me the HD668B because it looked the more sturdy and it has I think the best detachable cable design. Replaced the fake leathers with velour pads and added the extra foam inserts that came with the aftermarket velour pads that I bought and it definitely fixed the piercing high frequency.

[@PhonoDirect]

The information in this video is no longer valid as in the mean time Superlux did certain modifications to the transducers of both headphones. The current versions sound different - the "red" 681" have a typical "V-shaped" sound signature, bassy, but not overhelming and no piercing heigths either, with slight "sennheiserrish" veil in the upper mids. HD 668B is nicely balanced, not that bassy as 681, but not flat either, they have also better mids and wonderfull soundstage many much pricier headphones may only dream about. I woold say they sound better then Superlux HD-330, often celebrated as the reference of the brand. HD 681 has 32 Ohms impendance, 668B 56 Ohms impendance, so both can be properly driven with any better smartphone. But do not evaluate them out of the box - they do sound harsh, which is quite normal. All they need is a proper break-in of some 50 hours of loud load - so let them play something dynamic and complex in a loop for two-three days, covered by some quilt - and then listen and enjoy... definitely the best value for the money in the whole known headphone Universe :) And maybe then you sell your boring "Holy Grail" Sennheiser HD 600/650 and invest the change to some good headamp...;)

[@VVinstonSmit]

How can I know if a particular 668B headphone I own have the old or new transducers?

[@Wisdawms]

@@VVinstonSmit Maybe buy them from the exclusive agent for Samson in your region?

[@VVinstonSmit]

@@Wisdawms I alredy have them. Is there anything I can check? I have the box and everything.

[@AnonimoslawAnonimowy]

I have bought Superlux HD-681 in 2014 and in 2020 and they sound nearly identical. They still have the issue of too much highs and "sss"

[@marinoint]

I just bought a HD681B, which Superlux claimed to have good bass. Nothing is further from the truth; the bass is lacking and the highs are just like InnerFidelity described - very pronounced and piercing! I'm very disappointed at Superlux, and impressed by InnerFidelity's honesty.

[@thesagedear6286]

Everyone's ears are different. And worse, our audio characteristics change as we age. With that, I love my 668Bs. I use then equalized to my ears, where my son might find my listening characteristics intolerable. What I love most about them is the staging, which not enough of us talk about. I was hoping to find more discussion on the difference in staging between the 668Bs and the 681s. I may have to just buy them and hear for myself, and then give a different review on characteristics other then just EQ. What I can say about the HD668Bs (And the way that I have them equalized), is that the sonic reality is excellent. It is so good that many times I can hear production aberrations. There have been so many times when I have listened to a poorly produced digital track and felt the ground shaking beneath me (no subsonic filtering during production). The more pleasing times are when I can hear each instrument with so much clarity that I can actually hear what the audio engineers were thinking when they were placing microphones and mixing. I would like to think that other more expensive headphones are even better at this, but do I really need to know? I am so happy with my headphones that I should just stop looking and just enjoy my listening experience. I want to also state that I bought velour ear pad replacements at the same time I bought my headphones. I highly recommend them. I also use the EQ in FOOBAR 2000 and amp my HD668Bs (Aune X1s DAC Amp), which allow me to keep all my computer controls set to the middle for additional headroom before the digital stream hits the DAC/Amp. I have instruments and vocals bouncing around in my head for hours of critical listening enjoyment...

[@elfoxy1997]

I've had the 668Bs for several years and dropped them countless times, still work great!

[@ANSWERTHECALLOFJESUSCHRIST]

I love mine for any recordings that sound too muffled on my Koss Porta Pros, like old gospel reggae. It makes the music come to life. But for modern music with normal highs, yeah...ear razor blades like Tyll says, haha! I call them Baby DT 990s.

[@dado_ii8540]

Im using my 681 for over 5 years now, nearly every day. I got them along with a pair of AKGs, which I use to produce music. For listening outside, the 681 are better, because theyre louder and because they are that cheap, you dont have to worry about breaking or losing them. I used to roughly put them into my bagpack, and so after all this time the head ribbon broke some weeks ago - just fixed that with some tape. They survived 2 Smartphones already... I also dont think the highs are too loud, they are very close to a linear sound. I listen without EQ, good music and these Headphones dont need that. A big difference is made by the device youre playing youre music on. My Sony Xperia sounded so amazing, but after two years, the headphone socket broke - guess what I was thinking first, when there was noise coming out my Superlux...

[@profilename1337]

Am I the only person who thinks these headphones are not treble heavy? I switched from being a bass head to audio quality enthusiast because of these headphones, I think they sound great in all levels of noise.

[@IQuEsTI]

+Techno Niko i'm planning to do the same now i wanna hear more details in music, so far i only cared about the bass regarding the music i was listening to but now i'm enhancing my music library with other genres of music and need as linear frequency response as possible... brighter sound is even more acceptable :D

[@profilename1337]

***** Depending on your budget try the Philips Fidelio X2s, I think they're great. They are on sale on massdrop right now for $200 instead of the normal $300. I tried them and they are bassy, but it's a good quality bass, and the rest of the signature is really good. If you have the extra cash I recommend them.

[@eac-ox2ly]

I got myself some Superlux HD 681 and it's an amazing investment.

[@IQuEsTI]

replacing pads with better ones you'll get improvement both comfort and sound wise

[@thoru4367]

Voshchronos Mads kawaii

[@kacperuminski1547]

Quest ZMF Eikon pads decrease the highs by about5db and increase the bass by about 4db and make them pretty flat with an emphasis on bass. The pads are however twice as expensive as the headphones.

[@CrankCase08]

Eh? I bought the HD681 three weeks ago and found they had way too much bass which also caused distortion in the lower-mids. Perhaps you're thinking of the HD681F.

[@faizroo10]

CrankCase08 I'm bass lovers.Should I buy 681 Evo instead of 668?

[@XAEA-13]

I've had these for months, and have lots of hours in them. While my poor memory ruins my recollection of how they were when I first got them, I can say that now there is absolutely NO brightness in the treble, except on naturally sibilant tracks (usually lossy/compressed ones). I will also say that these things can handle a ton of power, no surprise given the 50mm drivers. Turn the bass up and crank it, it will handle the power. They sound great at any volume.

[@computerex]

I got both of these. Swapped out pads with zmf angled round, sheepskin. Instead of eq'ing I use a round piece of foam to attenuate the highs. Very nice headphones for the price.

[@behemothokun]

The trebles are kinda high on the 668B but they burn in over time, I recommend switching the pads to velour too (AKG ones fit), and yeah rolling the treble down helps aswell.

[@martinschnauder2184]

Best review for Superlux 681. Thank you.

[@jari121]

I have both 681's and 681 Evo's. 681's are much better nearly everything. They fit better for me and have better soundstage. Evo's have little more bass but less quality, soundstage is smaller and mids are worse. 681's sounds overall clearer and better. Evo's have extra veloure earpads and short and long wire with.

[@jari121]

@@Soulless1666 Yes. I took of the attached foam circles and they are much better after that. I also changed bigger leather pads and they are so comfortable now. I attached the bluetooth transmitter to its cable holder and now my younger son likes to use them 🙂

[@padraighmcneill]

I have the 668b and they really need an amp to shine. Most of the complaints disappear with a dedicated amp

[@chyans9as1]

I bought the HD661 cans the other day. After some burn-in time, I gotta say, it's the best investment I've done for 55 dollars. The build quality is top notch, and so as the accessories.

[@Trig242]

My opinion, looking at studio monitor headphones you want a flatter response. I would guess the 681s would be your best bet, if you were deciding between the two, and your budget is tighter. You just have to contend with the harsher highs. You can get a pair of AKG K240s new for just under $100 which are the studio standards and the headphones the HD681's design is cloned from. Hope this helps!

[@JohnGlen502]

HD681EVO are the best of the Superlux imo. They are not too bright and also have the detachable cord.

[@d0nj03]

Too bassy. HD662 Evo are the best from Superlux, especially after you tape up a few of the holes around the baffle, under the pads.

[@sephirotic87]

i've had my hd681 for over an year now and found the brights more subtle now than from the first day i bought then (they burned in nicely), yet i would like to know if the regular equalizer from onboard realtek audio in a Z68 is enough to put then on place? This phones had an amazing price, blew up lots of others overpriced "marketing BS" "top brands" headphones lots of hipsters friends of my keep buying.

[@ketarap]

I own both. I like the HD681 better. It has more clarity and in my opinion better soundstage than the HD668B. But both hp are very good for the price. You may want to change the ear pad tho coz they are not very comfortable

[@DanTraa]

Do you think the 3.5mm male thingy on the HD688B would last long? I've been eyeing on these 2 for a while now, I feel like the HD688B is a better deal since it has detachable cable. But, from a lot of reviews and pictures I've seen, it doesn't seem like it's gonna last that long compared to the non detachable HD681. What's your opinion? 🤔

[@ketarap]

@@DanTraa i only had my HD668B for about a year or less than that. I can't say much on the durability. But had my HD681 for 6 years for listening to music and playing electronic drums before the cable fail on me and i had it replaced with hd668B. But i liked the hd681 so much that i bought another one. They are cheap too. But the earpad is not very comfortable. You will be better off replacing them with the aftermarket earpads. For the price, you cannot go wrong with either one.

[@xamanto]

Thank you for the tip from where to equalize. The treble was killing me, now it's really awesome.

[@janmortensen9314]

I bought my first pair of HD668B 4 years ago. They came recommend from some of the local headphone geeks as the "best cheap headphones" around. I now own 3 pairs. I use them for gaming and music (better than Siberia). For office use be aware that they are semi-open, so another good reason keep the volume down at a reasonable level. FYI you can use the AKG K-240/270/271 velour pads

[@TheSaival]

Literally the best budget headphones, period. I am using my second pair in around 7 years and they absolutely beat heapdhones 2, 3 times as expensive.

[@diegotristan581]

so you're malaysian. go to lowyat forum to ask this question. may i know where i can find these headphones with the prices you have mentioned.

[@AUdioHipster]

Very interesting, altho most of the 50mm drivers tend to have the upper treble boost, they all are very different from one another, from thiner, thicker to duel cone, etc. to say one is better then another, is really personal choice, i could write a book on the pro's cons and difference's. 681 is very far from flat (after break-in,) eve tho bright with a smile to the mid's the low subsonic soundstage can only be found in very few cans, and most is very costly, Super-Slutz musical pleasure.

[@81giorikas]

Dude, just got these headphones just to experiment. Don't ever EVER trust no one but your ears-these are damn fine on the treble response. No two people hear the "same" but unless they changed the specs what this guy writes is as far from the truth than it can get. And where did he see the good build quality? These are a bit paper thin. Bottom line they feel cheap but sound x times better. You can't go "wrong" with these.

[@davidnguyen5936]

I may be wrong but I think everyone hears pretty similarly but since have different opinions. He's used to REALLY nice sounding headphones so of course this sounds worse. If your coming from low quality earbuds and what not they will sound very good.

[@81giorikas]

David Nguyen David, I am not (coming from worse). This headphones can be spikey but firstly I don't think he got them to burn in and secondly, if you actually write and produce your own music (as I do, I am a guitarist) you can actually know how do they treat a recording. "Musically" with some roll off? Or tell it how it is? They tell it how it is. Not exactly (they are colored) but they transalte good AND bad. Depending on source and material, they can sound bad but any good headphone should do just that. I don't agree with headfonia. He may be used to listening to a lot of good heaphones and I don't think he can be objective.

[@zorlagius]

@derbigpr500 sorry to say but your comment really comes off as a troll. Either that or you haven`t listened these headphones. HD595 are good phones but they really don`t blow 668-b off water or anything. barun432 is almost spot on his post. I`d listen to the reviewer who has very nice set of headphone testing hardware up and has good access on top of the line headphones. 668-b is well worth the price and puts many phones 2-3 times more expensive to shame. Price is not the same thing as quality.

[@vinniepearl]

They use the same driver unit. after burn in I've read people prefer them over the 668b. Some people claim the sound stage is better.

[@DonGateley]

My 681 arrived today and I listened quite a bit to my standard evaluation material before looking at reviews so as not to bring a bias. Results: I have exactly the same criticism and praise as Tyll. Their balance below the high boost range is similar to my AKG K702 which are the best sounding 'phones I've heard among a broad range of high quality devices. As Tyll says it is relatively easy to tame that high end after which they sound remarkably similar to the AKG K702 across the band. Amazing bargain if you are willing to apply a rather simple equalization up top. I also found the leatherette pads to be sweat inducing and would like more specific info on a set of velours that fit if anyone knows details.

[@MrStanley85]

Search for "Superlux HD-681 Velour Ear Pad" and youll find em - Also AKG 240 pads are fitting well as i've read but they are almost triple in cost

[@Microwave414]

MrStanley85 I own the k240 and their pads. When you get them they feel a fairly soft but after using them for over a week they do become rock hard and not very comfortable. I am sure the velour would be a better choice for most.

[@beeeatsme]

Great video. I watched this after getting the phones and after rolling the treble off a bit as suggested I had a much better experience with my portable audio player and these phones.

[@Chajew0]

I have bought them blind like 4 months ago and at first they did sound dissapointing. I tried them with my integrated (but on a high end motherboard) sound card and not only it was a little quiet even on max volume, but the trebles were unbearable. Happily though i have a set of bose companion usb speakers with their own sound system and it did fix the volume problem. Unbearable trebles still were an issue though. I left them to play random music over night and used them casually in the daytime and after a week or so the trebles stepped down and the mids n lows sharpened a little. After 4 months i am more than happy with them, they sound awesome. For a price of 40 euros i am more than happy, because i think they would easily beat the 100-150 ones with a good input (Yes i checked them on my mobo again, they still sound shit compared to what they deliver when connected to bose companion speaker system).

I have both Superlux HD668B and HD330. Without a doubt HD330 are much more natural, refine and correct. Soundstage is better. Warmer sound and pleasant. Bass is not so punchy, but is more deep/go down/ and rich. Mids are so much better. Sweet, refine and much more pleasant. Highs are not so rough and intense, they are much more correct and very refine. I hear so much more details in music. Sound signature is more natural-musical. HD330 are more comfortable than 668B. HD330 are better overall.

So ideal EQ for these is club/bass-y?

[@adilsokolovic12]

Which of these two have stronger bass ?

Does the 668B suitable for rehearsal session?

[@prahnitsua]

where can you buy the superlux 668b please post link or something

[@baronvonlichtenstein]

Just got the 681s. Hard to beat the sound quality for that price. Very neutral. In fact they sound closer to my DT770 than my Sony MDR 7506, ATH M50X and Sennheiser 280 Pro. But yeah, a tad bright and chinsy build quality.

pioneer hdj 500's for 90 if u shop around great isolation great bass and mids trebles the slightest bit harsh but only on like 2 songs soz might wanna look em up

[@TheOverhaul]

Would the 688b's work with an ipod touch with no headphone amp?

You technical talk at the start was a bit off putting (for me), but I liked the way you brightened up and gave a really honest opinion at the end. Thanks, great review.
