Looks great! The outside has a shiny black/ matte finish. Some parts look a little bit cheap, but hey - for less than $40 this is ridiculously good.
I do not know if this is standard for everyone, but my headphones came with an extra pair of velour pads. Those are really comfortable, but I found them to be somewhat scratchy after wearing them for several hours.
The top headband is an interesting design. It is one piece of adjustable material, with soft air filled pads placed in the middle. It is surprisingly comfortable and I can barely feel them.
The cables are nice and thick. Not very portable, but they feel a lot more sturdy than most other cables I've seen.
After burning in these headphones for over 40 hours, I feel like I can make an accurate judgment.
Although the HD681 Evo's are described as open headphones, they are closer to being closed than open. They leak very little sound, but have enough "openness" to have a great sound stage. You could use them in a public setting based on this, but I feel like they are too big to actually be portable.
The bass is definitely there. Nice and tight, but a little bit overpowering (nothing that can't be fixed with an equalizer).
The mids are somewhat lacking. If you look at the frequency response graphs, there is a bad dip around 4k.
The highs are what really took one star off this review.Read more ›
Definitely way more bass in the HD681 EVOs than the Audio Technica's. Bass was more boomy at first but after some mods and break in (velour, felt removal, covering up some vents, no filter), bass sounded a bit more controlled and punchy. If you want even more controlled bass then install a filter.
Mids and highs
Definitely there is a lot to talk about here. From what I discovered, there are two versions of the HD681 EVO's. The newer version comes with additional velour pads and a lot of little factory improvements (better rubber band, different vent covering material, etc.), the old version doesn't. The mids and highs vary between these two as well, mostly around the 5k range where there was a significant -db drop in the older version that has been since improved. The stock HD681 EVOs initially sounded a bit muddled, but after some break in, plus the mods, the sound became way more comparable to the ATs. The ATs still have the edge in sound quality and clarity, but for the price difference, I was absolutely impressed on what the EVO's were presenting to my ears. Besides, many EVO users have reported that these cans get even better after 100-150 hours of break in, so kudos to that.
The original A700s, although i have never tried them, are widely known to have some of the best and widest sound-stage for the money.Read more ›
I tweaked the Evo's just a bit: replaced the original pads with the velour ones they came with, adjusted (bent) the headband a bit to fit me better, and stretched out the elastic bands holding the inner headband in place to loosen it. Now they are super comfortable and feel right for me. I felt the highs were just a bit too veiled, so I removed the discs of thick felt covering the center part of the drivers (behind the visible fabric covering), and replaced them with a layer of thinner, standard "craft" felt which was more acoustically transparent. I suggest you don't make even minor mods like these unless you are confident you can do so without breaking the 'phones. There are always plenty of sites to suggest modifications and guide you through them if you choose to try.
There are better ones, but these are cheap, fun headphones, packing plenty of punch, great detail and clarity yet have a warm sound. They don't have the harsh highs of some other Superlux models, (such as the previous 681's), but do retain their great open, spacious soundstage and separation. I can't stop listening to them!
