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.
Summary: Gears used: HiSoundAudio Studio V, iRiver AK100
Tracks used: SoundProLab Absolute Sampler Album
Mary Stallings, Sunny
All in Lossless CD Quality 44khz/16bit
I think this is a great value for an IEM, to have this kind of sound quality yet very portable to carry around is...
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.
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.
Pros: Beautifully crafted; outstanding isolation and comfort; easy to drive; natural signature.
Summary: (edited note - for some reason I am giving these 10/10 for Audio Quality, but they are appearing as one notch less. Not sure why!)
To begin, would like to explain a little about my self and what makes me "tick" as regards audio equipment.
First off, I am no head-fier.
Pros: Real reference transducers. Very rewarding and involving. Completely addictive and immersive. Clarity, separation, dynamics and response all excellent
Summary: This is the best IEM among all my gears! The sound is balanced and natural. A big CON is about its undetachable cable... I think switching to balanced output will make it sound even better, but simply cannot try it unless cutting the cable, which will be a hard choice :(
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.
