I'd like a pair of very good quality, over the ear headphones available locally in Bangkok, Like to keep the price to not more than B5000.

I tend to listen to a lot of classical.  Most of the popular headphones here seem to be oriented to "Pop/Rock/Hip-Hop" and are bass heavy which does not work very well with orchestral music.  Sound quality and comfort (the lighter the better) are equally important to me.  Wireless would be nice but not necessary.

Recommendations and suggestions appreciated. 

B5000 seems like a lot. 

id go for this brand

But dont buy online 
find a store the prices vary to much on Lazada so no doubt fake is rife

and thats the thing about buying in SE Asia bloody fakes

I find Sennheiser are not usually to bass orientated 
When testing in a store one day with my Ipod
Most were <deleted> only Sony came through my sound test 

Finding Sennheiser can be hard but Sony usually easy
