The Golden Crystal IEMs are our flagship product and have one of the smallest dynamic drivers in the world – measuring in at only 5mm! The chamber of the Golden Crystals is processed by a CNC machine, making them perfectly flush. The cable uses 6N OFC and is hand braided and woven to improve strain relief and feel.

The Golden Crystals combine the ultimate tiny design with astounding sound quality and superior comfort. We consider them to be at the top of the high end universals market.

The Golden Crystal’s have a vast soundstage, a thick and dense sound and perfect instrument recreation. The sound is clear and transparent with a strong bass that brings the music to life.

The Golden Crystal has an extraordinary ability to recreate music as it was recorded and we feel that it’s the ultimate IEM from our line up. 20 Years of experience and practice have been put in to the design and creation of this IEM, and what you get is HiSound Audio’s idea of “perfect sound”.

The most important feature of the Golden Crystal is the tiny driver, which is only 5mm diameter. It is the smallest dynamic earphones in the world.

The tiny driver can make the earphone has many advantages: 1) The most comfortable wearing feeling. Normally the driver of the in ear phone size is 9-13mm, which is 2 times larger than Golden Crystal. That means the earphone is bigger and weighter which will cause the ear cannel very uncomfortable and fatigue, this flaw distract the mood from enjoying the music. The tiny earphone is very light and almost has no the upset feeling of foreign body inside the ear cannels except the music.

2) the tiny driver has the natural advantage on the mids and highs. All of the instruments have the same character that the smaller chamber the better on mids and highs. The Crystal has very transparent mids and very extending highs. It is benefited from the tiny chamber. The mids of Crystal is extremely liquid. The music is like the milk smoothly flowing through the earphones with the sweet and warm feeling.

3) As the name implying the Golden Crystal has the sound character of crisp, clear, and with the shining of gold. Especially when playing the strings, the highs seems has no end extending, the highs combined with numerous reverberation and other details.

4) The cleaning sound signature places the music under the clearing background, which can contrast every detail of the music, for example the vocal, you can clearly hear the breaths and the throat vibration of the singer

5) The enclosure chamber of the Crystal is made up of fine aluminum alloy, which is solid to ensure you long time usage.

6) The Golden Crystal has delicious musicality. This character is the symbol for the flagship IEMs. The unique musicality highlights Hisound’s music philosophy that is the ancient Chinese philosophy of gold mean. The Golden Crystal has the neutral sound signature, the frequencies spectrum is very balanced, this character make the earphone can match most of the music genres, thus greatly offer the value for the consumers.

7) The extremely dynamic sound: the Golden Crystal has very good speed on reproduction of the music, this make the music feel very dynamic. This feature make Golden Crystal is good for both of symphony and Rock.

The zero DB difference of the drivers:

We have specially designed the driver tor the Golden Crystal, it is the hi end Hi Fi grade earphone driver, normally the pairing of the left and right earphone can allow 1-3 DB sound pressure difference. The drivers used at the Golden Crystal have been handpicked by the senior engineers. We apply the 0 DB difference pairing standard for each pair of the earphones. (tested before assembled, there are some difference of the finished products). By this way, the sound of the left channel and right channel will have the stable and coherence sound. It can en sure the balanced sound and the accurate phases positioning.

The top grade silver plated twisted audio cable—Blast

Cable is the vital components of the earphone. Blast is the top grade cable which specially designed for the high grade earphones of Hisoundaudio. The following are the unique features:

About the sleeve of the Blast

1) The sleeve of the cable is made up with BASF. BASF Laser cable sleeve is very famous in the cable field, usually called PUR, It is composite material. It will be bright forever, which will not be discolored. The cable sleeve can tolerate with the temperature range of –40-+93 degree Celsius. The cable sleeve can resists the static interference. The safety grade of it is compliant with FDA food standard.

About the physical ageing experiment:

1)The Blaster cable has been simulated tested and get the following results: it has 70 months life under the natural indoor environment. It has 19 months life under the outdoor environment, and has 85 days life under the sunlight.

2) The bended and swinged experimenting: (with 90 degree swinging, moved to right and left with 45 degree of each direction, bended 60 times per Minute,), the Blast cable can pass 10000 times tested. The cable body can have the duration of 6-8 years under the condition of normal usage.(not included the jack and splitter. The jack and the splitter can have more than 30 months life under the condition of daily normal usage.

The core of the Blast:

1) The core cable is made up of the top audio grade silver plated OCC: The OCC core cable has excellent signal conducting feature. Many high end audio cable brands apply this kind of core cable. The manufacturing method of the OCC is very complex which the whole cable is made up with the single crystal copper. It is the historical breakthrough in the audio cable industry. The OCC has the following unique features:

1. The fineness of the single crystal copper is exceeded 99.999%:
2. It has 8%-13% lesser impedance than the general copper cable.
3. The superior flexibility, with the testing, the normal copper cable can only be twisted for 16 circles. The OCC cable can be twisted around for 116 circles.
4. It has superior conducting feature which is only next to silver.
5. Because there is no crystal interface and low inductance with the OCC, it is super on anti-interference. If there is the crystal interface, it will cause the signals reflection, refraction during the transmission of the audio signals. These flaws will make the signals deformation, distortion and attenuation.
   With above extremely excellent characters, the OCC is applied with the high end audio and Video cables. Many expensive hi end cable applied the OCC core cable.

Straight golden plated jack.

The Blast cable has adopted the durable and safety form of straight jack which many international earphone brands have applied including UE,and Creative.

The plastic part is made with two layers of injection plastic. The internal layer of the plastic is made up of LG5300 high density and harden PP material. The external plastic is made up of 86A TPE from Asahi Kasei. The metal part of the jack is applied the 3U/ 24K plated material from Korea. The good golden plated makes the jack benefits to diminished the connection impedance. It is fine and elegant.

Summary

The Blast is a fine hifi grade OCC cable, It is wove with the twisted method to avoid the interference. No matter the sleeve or the core cable, it is designed with painstaking. It has comfortable touch feeling, The appealing looking make the earphone very attractive, plus the wonderful sound quality of the earphone, It will tempt bother the audiophiles and music lovers.
