Our take on the AKG K3003i

by David Brown

rollover text

Reference-class sound quality you can truly take anywhere

When most audiophiles think of reference-quality headphones, they picture large over-the-ear cans plugged into a living room stereo. AKG blows those preconceptions away with its remarkable K3003i earphones. Don't judge these tiny earbuds by their size — these are top performers, delivering stunning detail and dynamics with powerful bass response thanks to AKG's hybrid driver technology. The K3003i's brushed stainless steel earpieces house three drivers: two balanced armature drivers for incredible clarity, and one dynamic driver to generate deep bass. The result is a superb listening experience you can enjoy anywhere, not just at home.

Color-coded sound-tuning filters give you more bass, great treble detail or smooth transparency.

Choose your own sound signature

The 3003i features a unique system for fine-tuning these headphones to your own personal specifications. Choose from three color-coded sound-tuning filters: bass boost, for extra power in the low end; reference sound, for transparent performance; or high boost, to bring out even more details in the high frequencies. Just screw the appropriate filter onto the earpiece, replace the ear tip and and listen as your music comes to life.

Yes, it has iPhone® controls too

Though the K3003i will sound great with your home stereo, you may want to take these highly portable earbuds beyond the confines of your living room. That's just what AKG was thinking when they added the in-line remote for use with the iPod® and iPhone. Play and pause your music, skip tracks and adjust the volume, while a built-in mic lets you take calls, assuming you're willing to interrupt a highly-involving listening experience.

3-Way Hybrid Technology: The AKG K3003i in-ear earphones set a new benchmark in audio quality. By pioneering the hybrid of one dynamic and two balanced-armature drivers in each earphone, AKG engineers have created perfectly balanced 3-way earphones with ultralow distortion, accurate mids, and crystal-clear highs. The combination of dynamic bass and dual balanced-armature drivers gives the K3003is excellent audio performance as well as matchless mechanical design. Due to the positioning of the speakers (the dynamic driver is behind the dual balanced-armature driver), the K3003i doesn't need any additional frequency switches. The result is less potential interference.

Balanced-Armature Drivers: Balanced armature (BA) drivers present high audio performance and acoustic efficiency for more sound from less power. BA drivers, exquisitely crafted for the K3003is, are distinguished by the outstanding performance on midrange and high-frequency sounds. Due to the diaphragm's high excursion level, the K3003i's dynamic drivers represent good bass quality and support the balanced-armature drivers for reference-quality audio.

Stainless Steel Housing: The housing of the K3003i is chiseled out of one piece of brushed stainless steel. This robust housing not only protects the earphone body from scratches, but also safeguards the K3003i's inner workings from physical damage. The K3003i's stainless-steel housing is robustly durable, timeless in appearance and easy to maintain, and it quickly adapts to your body temperature
for comfortable use indoors or outside.

Personalized Sound: The K3003i earphones provide you with one-of-a-kind personal sound-tuning capabilities. By changing the sound-tuning filters, you can adjust for three precise sound-output preferences directly into your ear. These adjustable, precision-machined mechanical filters allow for bass, mid, or high frequencies to be modulated. To change the filters for your preference simply screw on the filter of your choice (Bass Boost, Reference Sound, or High-Boost)

In-Line Remote + Mic: The AKG K3003i earphones feature and in-line remote + mic that is designed for use with your Apple iPod, iPhone, or iPad. The K3003i's remote control can receive or terminate phone calls, skip and pause music, and control the volume of your sound. And its stainless-steel skin gives the remote long life, endurance, and scratch resistance. Apple device compatibility as of 8/16/2012:

Crutchfield Customer Review (What's this?)
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.
Excellent sound!
I do not like the case it comes in and I am a little worried about the fact that the cable is not detachable.
