Pros - Price, Flat Response, Detailed
Cons - I can see the connector giving grief down the road.
Brilliant performers. Very detailed, I can spot imperfections instantly now. Great value for money. Definitely the best headphones under €100. Never even look at my hd 598's anymore.
Pros - Everything.
Cons - Comfort? WHO CARES!?
First that all. Im gonna say to all who wanna buy these that these headphones need Burn In, You will notice too much highs the first time. And yes, that was my first impresion of these, Too much highs and sibilances, but after a week I started to notice a improve in the highs and they started to sound awesome.
So lets start with the Sound:
Bass: Punchy/Fast Midbass, Sub-bass is weak, but overall they give enough bass energy.
Mids: Nothing special here. They´re OK. (Even after this edit I cant still say something bad/good about their mids, they are OK.)
Highs: They are bright, These highs are amazing, they give them more energy, trumpets, Saxos, Cymbals sounds amazing. I dont understand why some people say that these are too harsh or they have too much sibilances, yeah they have sibilances but I dont feel them excessive or annoying.
Also, their timbre isnt the best, somewhat dry,
Gaming: Very detailed and relly good soundstage, I remember my first COD 4 match with these, I even heard enemies across the COD 4 Map Showdown. That was awesome and since that day. I cannot play without them. (Edit: This is no longer the case xD).
Edit: I recently posted my review of the Superlux 681 Evo where I compare them a lot against these headphones: http://www.head-fi.org/products/superlux-hd-681-evo-black-professional-monitor-headphones/reviews/14340
Pros - Price, value, good fit
Cons - Ear-stabbing pain
I had trouble picking a rating for these.
At the price I paid ($36), these sounded good in many ways, with the exception of the highs, which I found to be harsh.
The killer for me, however, was not the highs themselves, but the ear-stabbing pain those highs induced very quickly (within a minute). This wasn't fatigue - this was pain. I'm not set up to measure anything, but I suspect they have a nasty spike somewhere in the treble range.
Fair warning - my taste doesn't lean to aggressive bright highs (lean more to HD600 or X1 signatures).
Leaving that aside (which obviously I couldn't), bass and mids were pretty decent for the price.
I found the fit to be quite comfortable (and I'm picky about fit).
If you have any issues with listening fatigue, I suspect you are going to find these unlistenable.
Pros - Lightweight, good bass response, comfortable, great sound for the price
Cons - Mids are not that good, not so neutral sound, highs are a bit too exaggerated
Fist of all, this is my first ever review,and English is not my native language, so please, have some understanding .
I bought these headphones 9 months ago, they were my first "quality" headphones. Before them I owned some pretty old phillips headphones which my dad boght back in 1994 when he bought our Technics amp,cd player,and tape deck player. The price of these headphones was around $50 , and I like good quality sound for a budget, so I decided to get them. I was by no means an audiphile back then, but these headphones brought me into the world of audiphiles. For the price, these headphones are very good. They deliver clear and crisp sound in most cases, bass response is very good, but the thing I didnt like about these headphones was the fact that these headphones are not really neutral sounding ( for my taste ).. They tend to lean towards higher frequencies, and that bothered me so much because this made the mids sound not as good as you would expect from monitor headphones. All in all, you get what you pay for, a good headphone that delivers great sound for the price. is nicely built , is very comfortable and sturdy and it definitely wont dissapoint you no matter how you use them.
Pros - The sound quality rivals $200-$300 mid-fi reference phones; neutral sound; clear; easy to drive; less than $50?!
Cons - plastic body, cables that come with are less than stellar, puts pressure up top of head with ATH wing design
Let me start by saying I don't normally write reviews on the official level, star system with graphs and all. I do look at them religiously when trying to find info on a HP, DAC, or AMP that's sparked my interest. So here I am reviewing on the Taiwanese made Superlux 668B which is quite obvious a mix of AudioTechnica's wing headband system, AKG K studio series body, with Superlux's driver. Aside from the last bit, obviously all are homages or clone of their respective brands. Not the first time one brand took from another however.
With that out of that way, let me start by saying at less the $50 shipped, not much can go wrong. The headphones look and might feel somewhat cheap on the cups but before you judge, plug the sucker in and have at it.
- Quite obviously the headband's wing system is something you'd find from AudioTechnica's line. Similar to AD900X and the likes. The headphone feels quite secure but the the two wings takes time getting used to. I'm hoping with time they get somewhat softer and less obvious. Aside from the two wings pads, the headphone is very light and does not feel like you're wearing a headphone at all. Clamp force is very good in gripping your head but not overly where it hurts (like a DT880 Pro when new). I've tried pointing my head downwards to try and get the HP to fall off, doesn't even budge. For reference I wear a 7 5/8" fitted hat, I fare on the big noggin side.
- The cups are made of plastic, they feel and look cheap. Aside from the opening of the grill, the cups look exact clones of the AKG K studio series (K240 for example). From the way the cups swivel up and down on the driver housing, the way the headband goes into the housing, as well as cable entry and run from one driver to another.
- The earpads are pleather and aren't too bad, although I can see some Hifiman velours or similar would do great on comfort. As is, it's not too bad. They're soft but not memory foam or anything fancy. The feel isn't too bad either, I've seen worse.
Now the most important part, SOUND.
They've been running for about two hours now and there's already a noticeable difference in treble. At first it sounded rough and spikey but after 60 mins it's calmed down quite a bit. From word around here, 50 hours would produce the final sound after burn-in. First these are what you would call reference type headphones, neutral sounding and fairs to the bright/airy side. No dark stuff here and if you seek a bass-head or a warm phone, look elsewhere. What I can say however is the clarity on these phones are fantastic. Dry sounding, it pairs well with tube amps for a more musical flavor but does well with solid state if speed and attack is of priority. With an emphasis in the treble end, they air on the bright side The treble does get too hot with poorly mastered tracks, definitely a bright and airy phone that does well when the music fed is greatly recorded (loud war tracks need not apply). The bass has a steep roll off after 60hz, sub-bass rumble is non-existent but bass is pronounced from 60hz and up. Nothing sloppy, but unamped the drivers can lose control when the sound swells. Soundstage isn't very wide, I would say comparable to the DT880's semi-open width. Instrument separation are great, you can easily follow different instruments in a piece without it getting lost when you've got 3-4 different going at the same time.
These sound to be about 85% straight from a cell phone, a plus if that's all the source you have or need to use it on the go. When amped, the HP can keep things tight and true. It doesn't take a whole lot to get these going as well, plugged straight to my Lenovo laptop I'm having to use 50% of the volume bar to keep things at a sane level. These are 56ohms with the rating of 98db/1mW according to the box.
I've never heard anything in the full size realm that sound like these at this price range. It definitely holds up to the hype and praises it gets as reference or studio quality. If you prefer a bright tilted phone with a dry and clear sound at less than $100 this is something that should be in your shopping list. At the normal price of around $40, these are a steal of a headphone. It's great as a value minded HP, backup, or something to let the kids chuck around. I'm one for great value and willing to spend the money if it warrants it so when something with great value comes around it definitely sparks my interest. If you're looking for something that won't leave a hole in your wallet that will compare very to mid-fi headphones, this is it. A definite listener's headphone, not very show worthy but when your friends ask what you spent on it, you'll look like you've done some homework with your purchase.
Pros - Neutral, light, flexable, trebble
Cons - Neutral, earpads are not the best, not a lot of bass
I found that the headphones are fairly boring if you are a basshead, but with the an amp, they can really drive, but a bit muddy at high volumes.
Pros - Gives a lot of pleasure
Cons - Needs high quality electronics !
I did test the HD-668B on my modified SMSL SD793II dac & headphone amp
where the sound is great and a bit more focused than the HD-681 (but both headphones are close)
After listening the HD-668B, the HD330 has too much bass with overall heavier sound
There is a lot of details, the voices shine.
The bass are deep & clear.
The trebles are very clear, when they are hard,
they only reflect the poor quality of the amp or dac
If you improve the quality of electronics, you will hear it through the HD-668 B
I am very impressed with the soud you get directly on a Samsung Galaxy S3 (Wolfson WM1811 DAC)
it is a pefect match, better than the 681 (too much spatial)
Pros - Cheap, good details and clarity, detachable cable
Cons - Cheap knock-off like, painful treble, missing bottom end
Just generally good and hard to find fault with. Not really deep low bass, but enough to be pleasant. Mid-bass has good presence and there is excellent clarity and detail in mids and highs. I found soundstage to be a little congested and overall a bit of a "thin" sound. While many people have praised these, I find them a little boring to listen to. The highs do not have an audiophile-grade "zing". Clamp force a bit high at first and ear pads could be more comfortable. A little more closed than semi-open so soundstage is not that wide.
While sound is excellent I'm not a fan of knock offs and these are knock offs of AKGs and ATs. If they had their own style I would buy more Superlux products, but their entire lineup seems to "borrow" design cues from others. It's too bad, because sonically they're excellent though after some time of listening I did not enjoy the highs as much. That tells me it's easier than we think to make good sound, but coming up with a great looking headphone - that's worth paying extra for.
Pros - superb instrument clarity,bright,clear mids,flawless
Cons - clamping force,pads could have been better
I have many audiophile headphones like sony zx700,koss porta pro,soundmagic e10,pl 11,skullcandy uprock,. out of whole least nothing sound better than my superlux HD 668B. this headphone is must for audiophiles who want their instruments to hear every note with ease. guitar sound will blow ur mind. may be not comfortable as zx700 but sound is awesome. bass is adequate. goes deep and low but rumbling is not present as soundmagic E10. u can hear every sound with ease. bass does not disturb the whole frequency response. sound is neutral,no fake sound,lower mids slightly recessed. it has detaching cable of 1m and 3m respectively. u can remove the pads and change with akg 701. though u will not feel pain for 2 or three hours(sufficient for movies). these are open back headphones and sound leaks through it which is not a problem for me. sound is spacious with excellent instrument separation. if you want a sound for $150 in $50 then these are for u. may be they are not built strong but if u look on the heart of headphone which is its sound, these are above par and are better than grados.
if u want a true audiophile headphone then look no further.
Pros - Cheap Good £150+ Sound quality better than ATH-ES700's for sure. Great Detacherble Cable wide sound stage.Extreamly Lightweight for size.
Cons - Needs Eqing can be sharp in the highs... Needs Good Burn in.
Lot's of Audiophiles own these they but can sometimes be like a wild horse that needs taming gotta eq and lightly amp to get best out of them - five times as good as
Audio Technica ATH-ES-700's for example IMHO not as great as the UE 600's. Fiio E17 sounded really good with these. A Valve Amp like the Bravo even better
