I owned the ed.8's for some time and sold them because I couldn't get over the pronounced warmth and the hyperbolic emphasis on bass, these are not even close to a natural sound signature, which is my preference. In all the other areas, except soundstage (which is kind of small) the ed.8's do well, but they are shiny (even the palladium) and draw a lot of attention if you wear them outside. Their looks make a good analogy to their sound, bling and baroque.
The t5p's on the other hand are more neutral, natural, definitely not for bassheads - a category the ed.8's serve quite well -, I find their soundstage and imaging superior, as well as their clarity/definition, overall a more balanced and better headphone. In regards to their looks, I love them, their built quality is on par to the ed.8's but they are understated, stealthy, classic and don't look like bling at all, I wear them all the time in the subway/street and with so many beats around, not a single head turns.
Neither of the two are perfect, but my recommendation easily goes to the Beyers. As for a portable closed that does this well, none at this level. I was extremely impressed with the shure srh940's, these would be my next choice, again, not for bassheads. Here is my closed "portable" can chart:
1. Beyerdynamic T5p
2. Shure SRH-940
3. Beyerdynamic T70p
4. Ultrasone Edition 8
5. Beyerdynamic DT-1350
6. Sony Z1000
7. Audio Technica ESW-10
