Adagio III

Optimizes airflow in the housing and delivers three-dimensional spatial representation and rich bass tones.
The Adagio series was developed over two years of intensive research. The result is a custom, dynamic 8mm driver unit. This compact driver unit unleashes a powerfully vibrant sound, delivering deep spatial expression and a vibrant "live sound" atmosphere.

An 8mm dynamic driver unit with a small aperture that delivers
powerful sound.
The development of a small aperture driver unit was an extremely complex undertaking. Being small in size necessitated extreme precision across every aspect. Small aperture driver units are prone to producing dull sound, and tuning is likewise difficult. Two years on from the first prototype we created, we completed
a driver unit with the kind of wonderful balance hard to believe with a small aperture and sound quality with
a sense of speed to it. The Adagio V driver unit is an exclusive model that has been tuned in conjunction with a stainless steel housing.
A BAM mechanism that delivers bass tones and deep, three-dimensional spatial reproduction
A BAM (Balancing Air Movement) mechanism developed for balanced armature drivers has been employed with a dynamic driver. By optimizing airflow in the housing, we have achieved the kind of natural bass tone reproduction and deep, three-dimensional spatial reproduction you wouldn't believe of a small aperture.

※ What is a BAM mechanism?
At final, we decided to focus on developing technology for the reproduction of bass tones and three-dimensional space with the full-range reproduction of a theoretically unproblematic single driver unit, rather than taking things in a multiway direction.We went back to the beginning and reviewed the performance of the balanced armature driver, focusing our attention on something we had previously overlooked ? airflow inside the housing. We developed BAM (Balancing Air Movement), a mechanism that optimizes airflow inside the housing through the creation of an aperture in the driver unit, which is usually sealed. While achieving bass tones and deep, three-dimensional spatial representation, which proved difficult with single driver full-range reproduction, we achieved a BA type that at the same time made for natural listening the user doesn't tire of.
A housing form that optimizes airflow at the front and the back
of the diaphragm
Optimizing the airflow in the housing is essential for three-dimensional spatial representation and bass tone reproduction. Aligning the shape of the internal aspect of the housing with the airflow resulted
in a functionally beautiful design that looks like a jet engine.
Original ear pieces that have high sound insulation properties
Two types of ear pieces are included with this product. The new E type employs two types of silicon differing in hardness for the sound conduit section and the section that comes into contact with the user's ear.
Compared to the section that comes into contact with the user's ear, the sound conduit section utilizes a harder silicon with grooves in it, so as to combine strength with flexibility. Can be fitted into the user's ear while maintaining its round shape. For the section that comes into contact with the user's ear, soft silicon has been employed, making for a comfortable fit and a high level of sound insulation.
Joining the E type and the five sizes it comes in – SS/S/M/L/LL – is the A type, which differs in terms of how airtight it is and in terms of bass reproduction (comes in three sizes). Please choose the size and type that is right for you.
An original flexible cable that suppresses touch noise
The ear pieces for the Adagio series are a new design. They have an even higher degree of sound insulation. However, heightening sound insulation properties means that touch noise from the cable becomes more noticeable. The material used for the wires, along with that used for the cable covering, have also been newly designed for the Adagio series. We've created a flexible cable that does not easily transmit touch noise.
BAM aperture that combines prevention of sound leakage and airflow control
BAM (Balancing Air Movement) aperture that adjusts airflow. An internal structure that hinders
sound leakage.
Color variation
Two color variations – BLACK and RED & WHITE. Use of these colors makes it easy to differentiate between left and right with just a glance.

How to wear the earphones
Identify the left and right housings using the L and R indicators inside the housings. Holding the product, insert them straight into the ear, searching for a stable position. Once you find such a position, play music so as to check the feel of the bass tones. Should there be insufficient bass, the fit of the audio canal with the ear pieces is not correct. In that case, either check again for a stable position or try another sized ear piece. Should the size of the ear pad be correct but the fit not quite right, washing the ear pad in water is effective.

* 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.
* Adagio utilizes highly airtight ear pieces. When putting the earphones into the audio canal and when removing them, please do so gently. Failure to do so may result in strain on the wearer,
such as to the eardrum.
* It is usual that a person's ears differ from left to right in terms of shape. As such, the optimum positioning of the product differs from left to right.
Sound quality reviews
The balance between well-rounded, powerful low frequencies and sharp, crisp high frequencies is very characteristic of these earphones. This is a model that delivers a good balance of sense of speed and depth of sound; we encourage you to try these earphones out using different music sources such as intense music and electronic music. You'll be blown away by the volume of low frequencies.
User reviews
It may be deemed a bit weird (?) but I bought Adagio II and III as a set.
These have the same strong bass tones, but high tones are also there and I think it's the ultimate "Don-Shari" ("don" refers to low-pitched sound and "shari" refers to high-pitched sound).
Thanks to the BAM mechanism, there's a vast sound field, and while it's "don-shari", there's little in the way of pressure when listening.
In addition to dance music such as EDM and Euro beat, you can also enjoy music with punch to it such as rock and pop music.
With III, you can enjoy "don-shari" on the default setting, without using an equalizer or bass boost function. If you listen to a variety of genre, then I recommend III over II.
However, if you're over middle-age, then Heaven II, with its high resolution and moderate bass tones, would be right for you.

Also, with both II and III, the earpieces deteriorate quickly, and after about a year, they easily come out.
Maybe it's because I use larger earpieces, but when I take the earphones out, the earpieces sometimes are left behind in my ears. At such times, I use the new E type earpieces, and they don't come off at all. Sound quality also improves, so I think it's a good idea to change over to the E type when you by the product.

Compared to Heaven V Aging, sound feels small, and it was necessary to turn up the volume.
(male, 40-49 years)
You get hit with low frequencies the likes of which you've never heard before.
I recommend this product to those who enjoy a great deal of volume and low frequencies that emerge right down to the lower bands.
I think there's a lot to be gained from experiencing this product.
However, I felt that the slightly crushed feel over a broad area and the reproduction of nasal sounds were a little weak.
