Summary: 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 $50 , and I like good quality sound for a budget, so I decided to get them.
Pros: Lightweight, good bass response, comfortable, great sound for the price
Cons: Mids are not that good, not so neutral sound, highs are a bit too exaggerated
Summary: I got my hands on an HD-668B today...
I still wonder what's up with these AKG clones... Is Superlux paying license fees to AKG so they may use their classic K 240 design for their headphones? One could certainly think so since a reputable dealer such as Thomann in Germany is selling them and they probably don't want to anger the Harman group :-)
Let's have a look at the headphone itself...
Pros: Feels solid, can play very loud, comfort, detachable cable, good value
Cons: exaggerated bass and treble, sibilant, looks a little cheap
Summary: Killer headphones for the money. Very hard to dislike. People who probably paid more money for AKG K240's (which sound inferior) would probably criticize them. I work in the audio retail industry and have experience with Grado - full line, Sennheiser - full line, AKG full line, Goldring, Beyerdynamic.
Pros: Sound- bass, treable, mids, stage accuracy
Cons: Not very portable, pleather cushions make you sweat when is warm..
Summary: No doubt, the 668 is a great value.
The sound is on par with some 200$ cans, and therefor really impressive.
But it is far from reference headphone level, specially the mids and balance are not even close. Built quality is surprisingly good for the costs, but still flimsy and made out of rather non elegant materials. The cable plugs are a nice gimmick.
Is it a winner? Definitely!
Is it close to Beyer 880 or Senn 600 class?
Summary: Got 2 pairs for US$65 ... gave one to a friend who is a bass-head (plays video games and runs it through movies [ DVDrips]) and kept one for myself.
After a year, here is our skinny on these El-cheapos:
Get the ugly part out of the way --> These boys are unforgiving and bright and WILL show up your crappy music systems. If the recording was brightly mastered/crap, if your source is bad, if your cables are bright (esp.
Pros: (in context of price) detail ,resolution, soundstage, fast-taut bass
Cons: (in context of price) bright ... bright ... bright
Summary: Amazing Headphones.
I 1st found out about these cans when I walked in on a new audio shop in our local mall. They had a lot of cans and IEMS available for audition so I listened to one. I was blown away with the detail and just about everything, there are also some Sennheisers there but these really stand out for me I couldn't put them down.
Summary: After a year with this amazing cans i think i can say a couple of things.
How the hell they can make this cans for this price?? China it's the answer...
This cans are amazing for only 20€, they do an unexpected sound quality for the price. It's not a Giant Killer but it's a Mini Giant Killer (MGK), i own a Sennhesier HD555 and -for sound quality- the HD668B are at the same level no doubt, but for 1/4 of the price.
Summary: I recently got these headphones from a german online store after reading the raving review at headphonia.com. While it left me quite sceptical, I thought ca. $35 isn't that much of a risk to take and they'd even be worth the price if they just had a decent sound quality.
But they haven't. They have an incredible sound, just like the reviewer at headphonia and the previous reviewer here have described it.
Summary: The sound is nothing like great bang for the bucks read in the reviews on forums. It's rather cold, thin, dull .. On any genre, from DnB over Guitar Rock to Classical music. These earphones are no fun at all.
If I had to pin it down, I would say this:
The worst thing about these headphones is that they offer zero "stage" and so little "detail" that it doesn't make sense for to listen to any good music with them.
Summary: This, headphone has weak performance on extreame bass respond (especially for editing movie sound tracks), i was return it back to the store after couple hours, and then compared it with the "new three" same model, but the sound are same, so i changed my order with sennhesier dj headphones, but none was better (superlux hd 668B & sennheiser hd 205) was cannot drive extreme bass freq.
