Hello I have been using the Razer Tiamat 7.1 headset for about 6 months now, however it has recently became faulty and i have been offered a full refund and i dont think im going to go back to Razer again this time. 
Im looking into getting a new headset/headphones which will mainly be used for Gaming, a microphone is not required as i have a standalone AT2020USB+ which i use instead.
I have been looking into closed headphones due to audio leak, and im a bit worried about my mic picking up the leak when streaming/in calls in with friends etc.
I have also have a Creative Soundblaster Z card which i feel could be useful for deciding upon headphones.
By budget is £150 just wondering if there is any recommendations out there?
I have had the ATH-M50 recommended to me, any others and reasons would be great!
