The first final products equipped with a controller.

• Sound quality design based on the latest acoustic engineering
  and psychological research results
• Clear sound quality that makes music resound pleasantly
• Sound creation based on acoustic engineering and psychology
• Unique swing-fitting earpiece mechanism

6.4mm? dynamic driver unit. The precision involved in assembling the parts for the driver unit is of the utmost importance.
The small-aperture 6.4mm diameter dynamic driver unit boasts an extraordinarily high level of
precision for this price range.

Highly rigid machined aluminum housing + Stainless steel mesh back. Compared to a plastic housing, this housing machined from aluminum with a alumite finish firmly supports the driver unit and suppresses unnecessary vibrations.  Fitting of a device for the mature listener, this is a design that has a simple shape and a high-quality texture matched with what could be termed classic sound quality. There is an aperture on the back of the housing which acts to extend the reproduction band of low frequencies. To prevent sound leakage from the apertures there is a filter inside, and stainless steel mesh has been added to the outside.

Single-button controller with microphone

The first final products equipped with a controller. With a single button, you can play, stop, rewind, fast forward and take incoming calls. The accompanying microphone makes hands free communication possible. * Certain music reproduction functions may not available depending on the model used.

To easily distinguish between left and right, the axis of the earpieces are different colors

Two types of silicon differing in rigidity are employed for the sound conduit and for the earbud that comes into contact with the user's ear. The silicon used for the sound conduit is more rigid than that used for the earbud, and by having groove processing applied to it, combines both strength and flexibility. Soft silicon has been employed for the earbud, making for a comfortable fit and a high level of sound insulation. To make it easier to distinguish between the left and right earpieces, one axis is grey while the other is red. By tilting the earpieces slightly and checking their color, it is easy to distinguish left from right even in a dim place. Comes in 5 sizes – SS/S/M/L/LL

Ear hooks that alleviate cable touch noise

With similar existing products, it was assumed that they would be fitted to ears of differing sizes; not only were they large in size, their appearance was rather too distinct, and it took a lot to get accustomed to fitting them. Having considered what the key to fitting the ear hooks was, we discovered a form that was smaller than existing ear hooks, that didn't utilize metal or resin wires and fit the ears of more people. We've achieved something that is slim and does not have a foreign feel to it, making for the kind of comfort that has you forgetting you're wearing them. Cable noise – the unpleasant noise that occurs when the cable touches the user's body when they are walking – is dramatically reduced.

Original cable that suppresses touch noise

Taking touch noise into consideration, soft, flexible coated material has been employed.When using ear hooks also, it moves flexibly, making for a good fit.

Aging

Aging refers to the phenomenon whereby sound changes with sustained use over a set period of time. With the driver unit, the extremely thin film that is heated and shaped vibrates to create sound. The reason for this is not clear, but the stress from the adhesive and the stress applied when shaping the film settles down as it is used, and it is thought that perhaps micro-signals move more freely. With this product, because of the small apertures, an extended length of time is necessary for changes according to aging become hard to identify. Generally, 150 ~ 200 hours of regular use increases delicacy and sound quality follows the intent of the original design.  * Since the reason for sound quality improvement through aging has not been clearly established, nothing could be clearly stated about aging until now. We have been checking this phenomenon, and have decided to express our opinions so as to collect as many questions regarding aging from customers as possible.

How to wear the earphones

Please refer to the earpiece swing fit mechanism while fitting the product; align the product at an angle where it fits smoothly into the ear. Please check the L (left) and R (right) indicators at the back of the left and right housings. Holding the product, fit into the ears using a slight twisting motion. Since sound quality differs greatly according to the positioning of the earpiece, move each earphone around while playing music until you find the position with the balance that suits you best. Once you have experienced this position, it will be easier to find subsequently.  The L (left) bush has a left and right identification protuberance so that it is possible to distinguish between left and right in the dark by feel. * It is usual that a person's ears differ in shape from left to right. As such, the optimum positioning of the product differs from left to right.
