then i might be going for the vsd3, any recommended ebay sellers for eu ?
I would actually recommend you go with penon audio. While they have an eBay storefront, they have an independent store at penonaudio.com Been buying from them for a long time and they have one of the best customer service, second to none.
I recommend you go for the newest VSD3 iteration with fixed cable, preferable with the upgraded cable as it has a better build quality than the stock cable, in my experience.
As others have mentioned, the Ostry are also another solid choice but I personally have no experience with them, but they are universally lauded. I don't know if isolation is high up on the list of requirements, but the VSD3 seals very well, in comparison to the Ostry Kc06/Kc06a. So be careful while using it out and about as it will cut out most of the surrounding noise, to the point that you won't be able to hear an oncoming car!

Here is a link to the
VSD3S: http://penonaudio.com/VSONIC-VSD3S?search=VSD3
The VSD3S is very much similar to the VSD3 but is more balanced sounding, with a bit more treble due to the bass being reigned in. This might be a better all rounder as you did mention your interest in Jazz. Either way you really can't go wrong, they are both worth their money imo.
Aside from the VSD3/VSD3S the only other ones I can really recommend are the Audio Technica
ATH IM50 and
IM70 but their design can be uncomfortable for some people, including me! and they come with an annoying cable :/
So yeah.... go with the VSD3 or VSD3S
