Have not managed to test the mic out yet, its in my hometown. Will probably be able to test it next week.

The Superlux HD 681 (non-EVO) is one of the best buys for me.

Pros:

It's light. Meaning it does not weigh you down if you play long hours.
It does not clamp on your head, so you don't get headaches.
It's very clear. As in it has no muddling effects from the lower end of the bass. This is not a bass heavy headphone, the bass is tight and fast.
It's cheap for the quality of sound it provides, much better than the Razer Carcharias which I also own.
Sound stage is great and separation of sound is also very good.

Cons:

It is not a full seal headphone, meaning you can still hear the outside noises if you are in a noisy environment. Though I prefer it this way.
It is quite a bright headphone, as it focuses on the higher spectrum of sound. Some may dislike this if they are into more bassy headphones.
The pads although comfortable, tends to make your ears sweat if you are playing in a warm room. The less clampiness of the headphone helps a lot though.
In Malaysia, there is no local warranty other than the 1st week personal warranty from the seller in LYN if he gives it.
The color combination of red/black and the design is dated.
No mic and unable to disconnect cables unlike other Superlux models.

All in all, I absolutely love it. It just sounds fantastic for less than RM100. I woulds recommend it for anyone if they are looking for a great pair on a budget. In Europe, they come with a very nice warranty so it's one of the best sellers there.

Because it is considered a budget headphone, a lot of people like to mod it to make it sound even more better. Google this if you are interested in those stuff.
