Summary: I got those from thomann.de for 28€, shipping included ;-)
I own and am used to Sennheiser px-100, cx880, Etymotic hf2.
I wanted to get detailed headphones like Etymotic hf2, but warm, and comfortable for longer period of time.
After investigating many models, reading review & comparisons, and actually testing headphones on my own, I got settled with Superlux 681EVO White.
With Superlux 681EVO i used: -3db for 30-150Hz, +4db 1-6 kHz..
Pros: deep and defined bass, warm, light, sturdy and easy to modify
Cons: big cans, isolation is weak, lack of airyness unless modified
Summary: AWESOME SOUND can't beat these for price and they re tough too .My teens love em and steal them on me all the time to watch movies with or listen to music ,me too LOL .Long cord can get tangled around things not it self so much tho and comfy to wear too.The bad too big to wear out or carry around ,these are made for home use .PLEASE NOTE since these are an open design you ll still hear the TV and people around you in the back ground so if you want total quiet try one of...
Summary: These cans need cc. 50-100 hours burn-in time to give you the best performance. Their sound is very good for the price. In some cases I even prefer them to my girlfriend's Sennheiser HD-650 (you can buy ~10 EVOs for its price), because the EVO has a very natural, realistic sound, while the highs of the HD-650 are rolled back and it sounds a bit artificial to me sometimes.
Summary: I'm still a newbie in the headphone category, just starting to try out all the hyped ones like SRH840, HD650/600 etc from the beginning of this year.
Now I'm left with this, HD600, and DT880. I'm thinking which one of HD600 and DT880 to sell at the moment, so HD681 is certainly doing something right here.
In terms of absolute detail there's no contest here, HD681 looses, but for overall performance at such a laughable price, it's certainly a keeper.
Pros: Construction, Comfort, Sound stage, Bass
Cons: Not the most revealing or detailed headphone
Summary: This will be a short synopsis of my findings after a few weeks with these.
What they come with: First of all, they are shipped with a good deal of extras, including a longer studio-aimed cord, and a shorter portable one, a carrying bag, an adapter to 1/4 inch, and, most surpisingly to me, velour earpads.
How they sound: First out of the box they sounded a bit tinny, with recessed mids and an unpleasant sound signature.
Pros: Durable, Fantastic sound, Large diaphragm, Interchangeable cords, Insanely comfortable
Cons: Bulky? To be expected with the diaphragm size though
Summary: My old headphones that I used at work were starting to show their age. I started doing some researching online to see what were some recommended low-cost headphones. I kept seeing the name Superlux come up but I had never heard of this brand before. After doing some reading about the Superlux lineup, I decided I would try out the 681 Evo's since they address some of the issues the older versions had.
Pros: Soundstage, bass, clear, and detailed, amazingly inexpensive
Cons: out of the box clamping force was high before i modified them
Summary: I'm member on a forum for bassguitar players and since a few years the Superlux HD681 are the most spoken of headphones on there. Because of the price vs basic sound quality. After I bought the DT770 pro it seemed funny ordering this one on top, for comparisment and good for recording too.
Because I really dislike the one with the red rings I bought the one with silver rings, not realizing that it has a different sound.
Pros: Cheap, good basic sound, cheap, decent build quality, cheap, includes carrying bag, cheap, self-adjusting headband and did I mention it's cheap ?
Cons: Harsh highs (solved by the filter mod), a bit tight clamping, all plastic (but makes it light) and not solid feeling.
Summary: The bass goes nice and low with adequate impact. Not too much to say about the mids. These things have too much in the high-end. They can be pretty shrill at times though a bit though an EQ helped a lot.
Comfort is definitely the worst thing about these. They clamp a lot and the earpads are made of a cheap, sticky, hard, pleather that peel off of your skin. BTW, Any earpads that fit the AKG 240 will fit these and I highly recommend replacing them; it's worth it.
Summary: People are dissing these for their looks?!? If you are buying any full-sized cans because of their sexy factor, you need to reexamine your priorities. If you haven't heard these, I'd bet you take them home when you do. For the tiny bit of $$ you'll pay, these are absolutely the best sounding cans you can purchase. College students, people on fixed-incomes and the thrifty audiophile will especially love these. Replace the pads with velour ones, if you want.
Pros: Soundstage, clarity, balanced sig with good bass, price
Cons: They aren't perfect... The ear pads are not the best. Not for the huge-headed, but what cans are?
