Summary: I apologize if I duplicate the findings of others. I read the other reviews, and I'm trying to address the things I thought haven't been talked about yet.
The current (it changes, it has too I guess) price (HD7 version) is 29.00 USD w/free shipping.
Pros: Excellent detail, good overall balance, extended HF response.
Cons: I didn't dislike the price I paid for the 668B, but they're now being imported into the US as Presonus HD7's. My box (from Taiwan) arrived crushed.
Summary: This review is based in my experience of almost 6 months with them, running 24/96 Flacs > Foobar2K > Wasapi > Asus Realtek ALC1150 + 4580 Op-amp > HD668B I decided to reboot my interest in audio gear and I was looking for affordable cans that could show me what I've been missing all this time,...
Pros: Detail, clarity, lightness (weight) Overall design: black, minimal understated, migh be a copy of AKG but if it works why fix it?
Cons: Materials feels cheap and build quality is average, feels flimsy but they can actually withstand some abuse. Sound signature might not be for everyone
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.
Summary: 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.
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
Summary: These headphones don't seem to add anything to the recording. It feels like they have absolutely no color of their own. Good recordings sound incredible good! Mids are delicious but not overly emphasized like in some phones.
Pros: Very natural, transparent, accurate, fast sound, fairly comfortable, nice looks
Cons: Headband can press on head a little and tight space for ears in earcups
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...
Pros: (in context of price) detail ,resolution, soundstage, fast-taut bass
Cons: (in context of price) bright ... bright ... bright
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,...
Pros: Sound- bass, treable, mids, stage accuracy
Cons: Not very portable, pleather cushions make you sweat when is warm..
