Looking to invest in a new set of cans

At the moment i'm using a pair Astro A40's and in looking in to a headset.

I was looking at the Byderdynamic custom one pros and also the superlux hd668b's, and the Fostex V1 and V2 from mayflower electronics   for ideas.

I'm just looking for some input to see what you guys would think?

Thanks

I got a pair of HE-500's and there great. Not really sure what your price range is. But i would give Hifiman a recommendation 

I'll check them out to see what they have, my price range is around $150-$250 CND.

 

The HE's are a bit out of your price range range. ATH-M50 with a mod mic might interest you. 

You should take a look at these http://www.amazon.ca/Audio-Technica-ATH-AD700X-Audiophile-Open-Air-Headphones/dp/B009S332TQ/ref=sr_1_1?ie=UTF8&qid=1421968762&sr=8-1&keywords=ath-ad700

They are for CDN150 so even with modmic they should fit your budget.

I just picked up a set of these today after reading many good reviews, I will be using them for gaming... and maybe streaming on Twitch if the mic is halfway decent.  Anyways... these are on sale for hella cheap until the 28th of January 2015: http://www.ncixus.com/products/?sku=96825&vpn=KHX%2DH3CL%2FWR&manufacture=Kingston

i was considering those but i kind of want to get away from gaming headsets, if i did get a pair i would wait for the hyperx cloud II which i hope will be good because i think that they teamed up with byerdynamic to make the first version and i hope they did for these too and the look like they damn strong build.

 

For that price i would possibly get those kingstons, even Logan said, that they are somewhat decent. I havent tried them yet, but in thi manner i would trust him.

I just got Sennheiser HD 558's, loving then. Coupled with my DAC, these things rock. I paid about 70 for the DAC and 130 for the cans. 

I really really like my K701s, the sounds is great, clear, great sound stage, and it doesnt need driven by anything powerful. The only thing i hate is the damn headband with the stupid bumpy bits, mine are old now so i ended up cutting them out, so much comfier. There are models without the bumpy bits though.

i wish i could get those but they are just out of my price range as there $384 on amazon.ca, i would love to try something from AKG because i've heard they make a solid product
