Hi
I have the K518 LE. Personally i really love it. It's the first headphone i buy and i'm absolutely not disappointed. The sound is great, i really enjoy listening music with it. Moreover the quality is very good. I bought it 8 months ago and it still perfect compare to other headphone i saw with my friends like Wesc.
Of course you will probably find other headphone better than this one but for the price and return, i think the k518 Le is a good investment.
After of course you should try it in shops or talk about it with your friends if they have some, the best opinion is often ours
That's all
Sorry if my english is not perfect
