Summary: These in-ear headphones sound outstanding from any source! I have never heard an in-ear headphone sound better than most full sized headphones. I would even say that they are better sounding than the HD-800 from Sennheiser.
Pros: Excellent sound!
Cons: I do not like the case it comes in and I am a little worried about the fact that the cable is not detachable.
Summary: The AKG K-3003 is at least close to a landmark Universal IEM, in my view. Pricey, yes, but one of the first Universals to aspire to the heights that the best of the Custon IEM's aspire to. They are well built (though some may not like the idea of non-detachable cables) and attractive enough. But the real issue is, of course, the sound, so let's get right to it.

I think this is a great value for an IEM, to have this kind of sound quality yet very portable to carry around is just amazing. If you...
Summary: Treble: a little bit piercing, especially on IPC. However, if connet this with the Hifiman player like HM-602, HM-603 or HM-801, the treble would be bright but not piercing.
Mid: clean and natural. Some might say it's lack of warmth, but with a warmth sound music player, the mid will be warm and full of emotion.
Bass: when I bought this, I thought this IEM lack of bass. After run for longer than 700 hours.
Pros: natural tune, full of detail, beautiful crafted
Summary: AKG K3003 is an important milestone in the development of IEM. It’s the first universal fit IEM that successfully combines dynamic driver and balance armature technology together. After owning them for 3 years, K3003 never fail to move me.
K3003 is hand crafted in Vienna with the highest standard of precision engineering. Its main component is made out of one single piece of stainless steel, this ensure an outstanding durability of the earphone.
Pros: Beautifully crafted; outstanding isolation and comfort; easy to drive; natural signature.
Summary: AKG K3003
Before jumping into the sound, I want to make a few comments on build and accessories, which I feel are important to discuss, due to how they may affect the sound and/or durability of the product.
Accessories include 3 pair of stock single flange tips that are very comfortable and well made with a good combination of thickness and flexibility.
Summary: LOOKS ===== I know some complain that they don't have a detachable cable but if you can live with that, I'd don't think I've ever seen a more beautiful looking set of headphones. See them in the flesh if you can and marvel at their beauty. SOUND ===== For the price you'd expect amazing. They are. For their soundstage, detail, bass and separation they appear to be 'magical.' COMFORT ======= For a moment I'd forgotten I had them in they were so comfortable.
I can laugh about it now but at the time "it ..., Amazon

Summary: I saw these headphones and realised that I had finally found what I needed for personal fulfilment. As I have no meaningful means of income I had to think on my feet. With a little research on the internet I worked out the basis for a pyramid selling scheme. I promised unbelievable returns and people lapped it up!
Unbelievable sound. Well worth the sacrifices made to get them!

Summary: Having deliberated for a few months, I finally decided to pluck up the courage and buy these outstanding headphones... at a steal! £1,000 may seem outlandish for a pair of headphones, but if you've just divorced your cheating ex and ended up with a hefty settlement, then you'll have no second thoughts.
