i'm trying to find some ~100e headphones that would be considered as an upgrade to my denon hp500 (which i like). They should be portable and have a good bass like the hp500 but keeping them as much neutral as possible , if there even is something like this for ~100e. i was looking at the AT WS55 ,are they any good and could they be considered as an upgrade?
Feel free to mention other options you know of.
Also keep in mind that i don't have the access to order the stuff all around the world i'm going to buy my phones from a local music shop :)
Thanks in advance
