Superlux HD-681 Evo BK

I bought this headphone for my homestudio. I record music as a hobby so I wanted a decent headphone without spending the jackpot all at once. My previous headphone was also a Superlux (can't recall what series though) so this seemed to be the right one for the job.

The first thing I did was open a heavy mix in logic an take a listen. What I noticed is that the sound of the headphone is very crisp and clear. Very well balanced sound overall. I played with the bass, mids and highs in the mix and I feld very happy with my purchase right away!

The headphone is very comfortable to wear, the cushions make sure that you don't hear to much noise from 'outside', and after wearing them for a couple of hours they still remain comfortable.

So: the sound is very good, what about the construction quality?

It's mostly made of hardplastics and thats fine, it doesn't feel fragile but it also doesn't feel like it won't ever die on you. The main reason why I gave the quality only 3 stars is because the rubber around the jack cable is already torn on some places...

verdict: It's absolutely a no-brainer to buy this headphone. If you're like me and don't do music professionally you only care about a good sound and a comfortable headphone, and thats exactly what you get!

I had been using Sennheiser HD595 for several years until the headphone cable got caught between the armrest of my chair, which eventually caused it to fall down to its' death. So looking for a replacement headphone with a similar sound clarity but with a far smaller budget in mind... I wasn't very optimistic to say the least.

The Superlux HD-681 Evo arrived in a box where the product laid well packed. It includes a 3.5 to 6.3 mm headphone converter as well as two different cables (1 metre and 3 metre). The converter is not of best quality, it actually uses a clip-on in order to stay secured. I didn't like that. The cables are straight, quite thin and the connector seems to be adequate. They also included extra velour pads, which I as a matter of fact immediately replaced the pleather pads with (pleather pads are by default installed on the cans).

For a 28? pair of headphones I must say the build-quality is surprisingly robust. However, at the beginning I felt quite a force pressing around my temples and ears. To alleviate this, I let it stretch for several days (I used the triangle-shaped cardboard package which the headphone was wrapping itself around, plus some books for further stretching). After a few days of stretching the clamping sensation was gone and by now I had already burned them in some (I used various music and a burn-in soundfile found from JBL's website). If I recall correctly, someone recommended at least 100 hours of burn-in for this model.

The sound. Oh the sound... Clear. Wide. That was my first impression. For a headphone to sound this good for such a low price is nothing more than a bargain. The clarity and separation of instruments is something I was greatly pleased with, especially when listening to soft rock or similar music. While playing Toto - Africa from beginning. Kick drum, soft snare, cow bell on drum kit in the left ear, extra handheld cow bell in the right ear, congas in middle, succeeded by the famous synth-riff. Wonderful. However (be warned)! The highs were too high to my ears. I have some sensitivity to sibilance and I feel that these headphones amp those frequencies quite adamantly. The bass is very much present, but it is not presented in a controlled manner as it interferes and sometimes overpowers the mids in other songs.

After using these headphones sporadically (letting them burn in when not wearing them) I always felt the highs were unbearable. They were simply too pronounced and sharp for me to enjoy 90% of whatever music I was listening to. Well luckily there are two ways of fixing this.. Well, actually three, but two of them are very similar just differentiating in methods, so let's stick with 2. EQ (Equalization) and physical modification of the headphone.
After playing around with an EQ, I mostly adjusted the 5k and up, by simple lowering them more and more the higher up I advanced in frequencies. Now this may be placebo, but I felt the presentation and sonical experience turned muddy and veiled. So I tried a second alternative, add cotton pads (those round, white soft pads used for facial-cleansing and make-up removal). I simply added one pad inside each cup, fitted them right through the opening without needing to open the cups up, using my finger to slide the pad under the velour pad edges. To explain my initial reaction: it felt right. The sound was just the way I liked it, similiar sound profile that I was used to from my 595's. The sibilance was gone and I still found the headphones sounding enjoyable. Now, as I said, it may be placebo or it may not be, so it should be up to everyone to try an EQ or cotton pads. The bass is still quite the same. To be honest, I don't recall exactly how it sounded without the cotton installed, but hey, these cost 28?. Some sacrifice is inevitable.

Final thoughts.
These headphones are so cheap, that... that they don't sound cheap? That didn't make no sense, but neither does the price tag for these. These cans sound to my ears as a pair of 100? (or even more) phones. But because they are inexpensive, these have become my main "fun-phones", that is, I do not really need to worry too much how I'm handling these, whether it's at home or on the move somewhere else. It's carefree. It's fun. The sound is also quite exciting for watching films as the bass is very present when needed. Rock music goes quite well with these, as well as EDM. The only thing I really can't do with these, is enjoy classical music, but I already knew this prior to my purchase. The HD-681 Evo's bass is simply not very controlled, too much interference is going on around the low mids which takes away much of an orchestra's presentation. But remember, 28?, sacrifice is inevitable. I often use these when playing VST pianos in Cubase, it's a pleasure.

Ok just buy them already, have some fun.

I've had 3 pairs of these headphones, which is a testament to how good these sound and how badly their cable is designed.

For the price offered I don't believe you can get a better headphones experience, the sound quality is great, with a warm bass and ever so slightly recessed mids and highs. I've only sensed this sort of clarity and balance in headphones 80 euros and up, which at almost triple the price of these just goes to show how good of a deal these are. The sound stage is also very good, the open design allows for a really pleasant listening experience. They are also immensely comfortable, the adjustable headband works like a charm, the construction is pleasant and the velour pads are a fantastic addition to a 30 euro pair headphones
(They come with two pairs of pads, the faux leather ones that already come with the headphones aren't very good) I've mixed on these headphones for over 5 hours in a row with only mild discomfort.

So the reason why I don't rate these a perfect 5 is due to the cable design, the male jack on the headphones is just too flimsy and short and always ends up ripping with extensive use making the detachable cable useless. Either make it longer or sturdier, it's the only thing holding these headphones back.

Overall fantastic headphones with one exceptionally bad flaw.

These cans are the reward for anyone does a little research and try new things and the pricing means it was a low risk proposition.

If you read the reviews, you'll see that very few people find fault with the sound : it's revealing, untainted (no apparent bias) and no apparent weakspots. The sound is warmer after several hours use and they are comfortable for long listening sessions.

In the interests of balance, I should point out a couple of tiny points that i like less : they are a bit large (but not heavy) and they look odd anywhere outside the studio. They are also semi-open - so there is noise leak if you're thinking about office use.

For those seeking comparision, or a frame of reference, I've retired my Grado SR 80's because of these. I previously liked Sennheiser PX100s, and Equation Audio RP21 and AKG eth55. These have the better sound, they are the most pleasing overall, and the cheapest by a mile. I havent heard better and for a comparable sound, you'd have to spend around 150 quid for something like Sennheiser HD25s - and I notice other people here rate them even higher !

The fact that Superlux do it for this price makes me very cynical of more establish brands and their pricing. Well done Superlux.

One the one hand, there is a kind flimsiness to them, on the other hand, they are light. I don't know if you can have one without the other, but it seem a slightly sturdier build wouldn't hurt.
The sound is good. Airy with a wide stereo field. Nothing major to remark on, good or bad.
The construction is open, so there is much leakage and little isolation, so they wouldn't be my first choice in a studio situation.
On the flip side, isolating headphones have to squeeze your head, which these ones don't, not much anyway.
The low weight and lack of squeeze, combined with included velour pads makes it possible to wear them for hours on end.

These headphones are absolutely brilliant value for money.

The sound is very revealing. Mid bass is somewhat emphasized as with headphones like the ATH-M50, but it's not muddy enough to overwhelm. Excellent positional/directional accuracy and instrument separation. There wasn't a song I listened to that doesn't sound great through these headphones.

It's worth remembering that these are not closed headphones, they are semi-open. Sound will leak, both out and in. Best to avoid using these in noisy environments or when you don't want to disturb others.

Attractive shiny/matte plastic looks with a chrome accent, but the glossy plastic attracts a lot of fingerprints.

Solid construction with a replaceable cable - helps to prevent damage to the connection to the headphones themselves. (great, since this is what caused my last set to die on me after getting trapped in a swivel chair leg.) The self adjusting headband is easy to use but may need some time to stretch in order to easily fit bigger heads. (Like mine, unfortunately.)

They're lightweight, and can easily "disappear" and feel like you're no longer wearing them. The cable does however causes a lot of noise if dragged on clothing, etc..

Not exactly portable, but since these are studio headphones, and not really intended to be used when out and about, this can be overlooked. The inclusion of alternative velour earpads is a nice touch. It's down to personal preference, but I think they're much more comfortable and provide a better sound than the pleather earpads included.

Overall, these headphones compare very favourably to sets costing much more, and are definitely worth considering if you're on a budget.

I have used superlux bewore, and for their price. They are really worth it. They sound like ten times more worth than they are, but that come, of course, with some caveats.

Design is nice, and velour pats (which you should use) make them quite comfortable to wear. There isn't much of way to adjust then, but their design somewhat makes it up, their headband adjust to shape of head etc.

First one I got had out of package had contact problem and they didn't work propebly. Thankfully, thomann was true of their word of their guarantee, and send immediatly another one to me. These have worked perfectly, so it was just a "monday pair", I'm willing to believe. Defects happen, I guess. And given the sound quality, i'm very willing to forgive it.

Sound is awesome. Very open, pure and clear. You wouldn't believe you can get this sound quality at this price, it is pretty amazing.

All in all, very beautiful sound quality with quite cheap and i guess fragile body. But at this price range, it's pretty much a deal. After all, they're only 30 euros...
