well, I'm currently speechless and so thought that I'd type out exactly how I feel, as I've just been completely and utterly blown away!
My Ultrasone PRO 2500's arrived today, and wow. wow. wow. wow. wow.
Now let me make this clear I'm no audiophile, and (you're going to laugh) I upgraded, I got these as my first headphones, and so the highest end earphones I've ever owned are a pair of £40 Sennheiser CX 400 II's. Although making such a big step up does have it's advantages, and that is that when you put on some decent headphones, you get literally blown away.
These apparently need 200 hours or more of burn in... And I'm using these un-amped straight into my computer, and I cannot believe the clarity and soundstage. It's ridiculously good.
What happens if I try some £1000 headphones that have been burnt in? Well' i'd love to see how they can be an improvement to what I'm currently hearing, I have no idea how they'd justify costing 5 times these... They surely can't sound 5 times as good.
So yeah, I have no idea if anyone cares but I'm a very happy customer and would like to take this opportunity to thank everyone on here who has helped me, this has got to be the most informative forum I've ever signed up to. Saying that, anyone who can get me to spend £250+ based on their opinion alone must be doing something right, so thank you all!
P.S. I said how I was skeptical about Simply Electronics (the website I ordered from) as they were so cheap and had bad reviews, but honestly, and I admit I may have got lucky, but based on my experience alone I'd recommend them to everyone and the service was terrific, extremely polite and helpful email replies, very fast replies too, and my order shipped in just over a week, they kept me updated at every step of the way.
Amazing. Now to get my Fiio E7 and E9 and see how much of an improvement that will be! I have no idea how it will improve what I'm experiencing right now.
