Which one? HD600? HD650?

Contrary to what other say, I don't find 681 sound like 'V shaped equalizer', in fact I found it quite balanced even for someone like me who don't like too much bass. The bass is plentiful and comes in a large quantity but it doesn't overpower the entire spectrum so it doesn't annoy me who like more neutral sound, the high is quite nice, its way better than Sennheiser which have some sort of 'veil' on treble but its not piercing or shrill to hear. There is some sort of air too, feels like you hear through speaker. Headphone itself is light and very comfortable even when wearing glasses.

For the price, I don't think any other headphone could come close. Highly recommended for someone who new this audiophilia world
