I prioritise sound quality, i will be listening to music and playing games often on my pc, so i want really clear sound and for microphone its ok if its durable and sound is understandable. So, my budget is like MAX 110 euro. I was thinking about Sennheiser HD439.
Headphones+mic is a good choice. I'd say a cheap mic and good headphones are the best choice or you can go with something more balanced with pretty good headphones and a better mic. So here are links to Amazon Uk
The Sennheiser HD518 and the Zalman is a good choice, but if you feel that your too close to being over your budget go with the HD439 instead of the HD518's and the Zalman (the HD439's should be lower priced than the HD518's)
As I said before I would go with a cheap mic and good headphones, but if you want better mic quality go with the more balanced combo, but you're going to be losing some audio quality. Not to mention that the HD518 is open meaning your going to get a bigger soundstage which is better for gaming.
