Summary: EXECUTIVE SUMMARY
1. Not coherent throughout the audio band:
a. Overall neutral, but but but
b. What’s up with the peaks in the upper mids/lower treble?*
c. Little bit bloated in the bass
d. Bass not keeping up with the mids/treble
2. Little bullet design = comfort/fit that blows monkey chucks
3. Mid-fi resolution
4. Aren't IEMs supposed to isolate?
Significant sonic issues indicated in red.
* Pop and rock do not sound good.
Summary: Short Review: All observations made with the high pass filters. Naturally I listened with each of the three filters, but the high pass was my preference.
I really liked the tuning of these. With the K3003, you get an approximation of a neutral sound in terms of a good balance between treble, midrange and bass and the filter system gives you a means of adjusting this balance (at a cost of slightly loss of detail with the non-reference filters).
Pros: Great Tuning--These Are Fun To Listen To, Good Detail In the Midrange And Treble
Cons: Incoherency Between The Drivers Is Noticeable, Harsh treble with best detailed filter, detail loss with others, High price, Reliability is a concern
Summary: These shiny, luxurious little in-ear monitors that come in a very exclusive box sure feel very expensive in terms of look and feel. They shells attach behind your earlobes and rest comfortably there. This is the most comfortable in-ear headphone I've worn.
They can be driven from an iPhone as well as an amp, sound will not be any different.
The sound of these didn't impress. They have that clean, clinical sound yet lack the clarity to sit at this price range.
Pros: Beautifully crafted, very comfortable, clean sound, different filters to choose from
Cons: Piercing treble, lack of warmth, very overpriced

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: 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.
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. My only issue with them is that I require a bit deeper insertion due to the shape of the housings and tip...
