What can I say? They're a sub-?30 pair of Superlux headphones.
Having tried the old HD-681s which were an amazing pair for the price, I can say that the Evos are that and bucket-loads more!
I was pleasantly surprised upon opening the packaging to find two cables; a short one, perfect for use with a portable device and a longer one, perfect for use with, well, anything that's a little further away. The headphones themselves have a male 3.5mm jack on a short cable extending from the left ear cup. This allows you to replace the cable with any after-market cable should you so desire. As both cables are female on one end, they can be combined to create what is possibly the longest cable I've ever seen on a pair of headphones out of the box!
Also included is a small clip which helps ensure that the attached cable does not come lose, but use without it was not an issue in the slightest.
A 1.4 inch jack is thrown in for good measure along with a second pair of pads made form a soft, breathable fabric which is extremely comfortable and is great for longer wearing sessions.
If you've owned or read/watched/heard reviews of the old 681s, you'll have heard many say that they had quite sharp and fatiguing treble. A common fix was to place a cotton pad in the ear-cup to act as a sort of filter. This has be addressed in the Evos and adds even more to their great sound. I primarily use these for light gaming at times when I'm not at liberty to use my surround setup and as such, the semi-open build lends itself quite well to my needs.
The sound-stage is excellent without sacrificing isolation and without having to fork out a few hundred euros for a much higher end pair of cans. On top of that, the detail throughout the spectrum is great, with clean highs, warm and 'full' sounding mids and deep, mud-free bass.
Overall, these headphones are hands-down the best pair I've yet to use in this price range and are a must have if you're looking for a great value pair to add to your collection, or maybe to start it!
