Headphoneus Supremus
There is a link at the base of my posts. If you refer to source, I use mainly iPhone 5S with or without audioquest dragonfly.
As to the Portapros and comparable gear. My friend borrowed my stuff, tested it, and wrote it up here:

Those AKGs mentioned are interesting: lots of oomph, zero soundstage, excellent fit. A crowded orchestra but a great "London Calling" by the Clash.
Very interesting, will read that for sure....was eying the YAMAHA RH5MA.....got quite a persistant fan base. But, the Takstar PRO82 I just receive will perhaps calm my need about portable headphone. First impression is very very promising. Treble extension is great, detail and bass too. So comfy too. But can't talk more, just listen to electro (M.E.S.H & Beatrice Dillon) right now.
Hum, for your source....well, I guess I will not begin talking about how I hate Iphone. Your a courageous man Otto hehe especially if you plan getting new Iphone without line out (audioquest look quite okay tough).
