We’re used to the miniaturisation of technology in laptops and phones. However, audio specialist Harman Kardon has been working on ways to shrink the components in earphones and audio equipment.

At IFA this week, one of Harman’s brands, AKG, was showing off the K3003 earphones custom-made and custom-tuned earphones that will go onsale through Harrods and Selfridges later this month. The earphones are the first of three planned designs to come to market and are the product of several years of development and design. They weigh only 12 grammes and have a frequency range of 10 to 30kHz.

The AKG K3003 earphones contain a speaker and separate drivers. AKG says "the K3003 sets a new benchmark in audio earphone quality with the combination of one dynamic and two balanced armature drivers".

AKG says the K3003s are the world’s smallest triple-driver earphones. They will be anything but mass-market: the drivers inside each earpiece are handmade, owners get a custom tuning kit to minutesimally tweak the audio according to the type of music being enjoyed, and there’s the small matter of the £1000 price tag.

The AKG K3003 earphones are individually numbered and presented in a personalised suede pouch with a form-fitting interior to keep them tangle-free and in pristine condition. A selection of moulded sleeves is included, while the 1.2m cable includes an in-line volume control and microphone, making them ideal for use with smartphone.
