Best sounding headphones you have owned?

What headphone own natural timbre and own a deep bass clean and with no leak in the mids and more importantly an "out of the head" speaker like impression with great hall recordings or church one for example ?

I enjoy that only with my Akg K340 , none of the others headphones i had listend too ...

I dislike almost all headphones...

I apologize to repeat myself  wanting to be clear...

If someone know which headphone did the same please give me his name ...

Meze Elite, why :-) Sit right now on my head.

I am very much into headphones and yet I don't post here. For headphones there are better websites. Tip-there is no best. Lots of great ones. Ever try to move around a range of loudspeakers from your source and amplification? Not fun. Ever switch from a variety of cans? Easy, fun, and rewarding. Headphones are to high- end audio as polygamy is to, well...

The absolute best sounding headphones I have tried or owned, including quite a few of the better models, is theJM Audio XTC 2. The price is insanely low for what they represent in both build quality & sound quality. Alongside this JM Audio offers splendid customer service. Take a look at some on line reviews.

I fully agree with the above post by bjorn154.

I recently got a pair of the JM Editions XTC-2 open backs. They are superb hheadphones. The ordering process is unique in my experience. You can actually hJM  tune the headphone to your sound preference.                                                 Build quality is also superb.           

I have had many headphones including a few TOTL.

The JM XTC2 is the finest set of headphones I have heard. I attribute that to the great communication with John regarding preffered sound.
