Sorry for my poor English... you mean the shape and size or accessory? Anyway, I think some of you are interested to know these two aspects. I tried Erlkonig before but I do not own one. I think the size of Phonix is a little bit smaller (thinner) than Erlkonig and fits my ears well, very comfortable. Regarding the weight, I am sure Phonix is much lighter than Erlkonig. Since the casing of Erlkonig is silver, I think it is better to warm the Erlkonig briefly before putting them onto the ears in winter. On the other hand, the casing of Phonix is carbon fibre, no such issue and have better resistance to weather I think. According to the VE distributer / advertisement in Hong Kong, the stock cable of Phonix is 4-wire 23 AWG silver & gold alloy and OCC copper cable with 2.5mm connector. For EXT, the stock cable is 8-wire 28AWG gold plated copper cable with 2.5mm connector. For both EXT and Phonix, a new VE 2.5 to 4.4mm adapter will be included, which uses gold plated copper connector and audiophile grade POW insulation materials (I think this is used in the casing of the adapter). For carrying case, Phonix will come with a genuine leather case and EXT will come with an aluminum case (the advertisement is a bit confusing, it seems there is one more leather pocket as well for EXT... ) Acutally, there was a display showing the accessories of Phonix in the Show, but I didn't take a photo of the display...
