Description

Introduction 

Earphones DIY Labs team proudly offer Taichi, a Sound Isolation Sport Earphone in audiophile-grade quality. As the fundamental of Taichi is to balance between “Yin” and “Yang”, we offer 2 opposite options to satisfy even the most picky Hi-Fi enthusiasts.

“YIN” is characterized as warm, high fidelity to the original. It performs best with traditional audiophile musics, symphony, most pops and country musics. It is build with Ivory white shell, Shure silver plated 6N OCC cable and 3.5mm gold plated jack. The inside is a pair of 10mm dynamic drivers from Sennheiser IE80S.

“YANG” is with super bass, crispy highs, and works best with rocks, action movies or sound tracks. It is build with Meteorite black shell, Monster iBeats 5N OFC cable and 3.5mm gold plated jack. The inside is a pair of 10mm dynamic drivers upgraded and re-tuned based on Sennheiser IE80S.

Although they look different, the shell of both YIN and Yang is built with same ultra durable material as Apple Air Pods. The human engineering design of the shell makes it perfectly and comfortably sitting in the ear, and block up to 37 dB of ambient noise. So it is

We also offer all separated components (DIY Kit) of both YIN and Yang, so you can assemble and tune them by your self. It only requires basic soldering and gluing skill and a few hours. Don’t want to take the risk of messing something up? No problem, choose the Assembling Option and let our professionals make it for you. No assembly needed.

How does the YIN sound?

The IE80S Dynamic Drivers make the build very much like the original IEM – we measured and observed 95%+ similarity in the Frequency Response with the original earbuds delivered by the manufacturers.  

As reviews of the sound quality could be very subjective, we collected some 3rd party impressions on IE80S which we think also apply to our kits, together with our own impressions. This is only for your reference and we have no grantee that you will have exactly same impression. 

Sound signature

Reasonably balanced throughout the highs and mids, with a gradual emphasis towards low bass. 

Bass

Very powerful bass.It’s authoritative and the best choice for basshead audiophiles. Some reviews said the sub-bass of IE80S is not as deep as IE800, while we think they must not have measure it carefully. Benefit from 10mm drivers (3 times larger than IE800), the kit offers much better fidelity (<1%) and the bass sounds natural and real (unlike IE800 which has the bass a bit over bloated). As the bass is not adjustable as IE80S, we set it to default (mid) level which works best for most users.

Mids

The mid-range is clearer and more resolving in comparison to the IE80. But still, the mid-range is fairly recessed compared to the bass and the treble peak. As a result, the vocals do not have the immediacy, size and density. So this is not an IEM for vocals, especially the female vocals as they may sound delicate. But given the enhanced bass, there is a certain thickness to the mid-range that helps the presence adequately, especially the male vocals. The mid-range overall is a bit relaxed. 

Note, we noticed this well known character inherited from IE80S and working on a solution. 

Highs

The treble was anything but bright. It did have a small peak in the lower treble at around 6kHz. Whether this brightness is a positive or a negative aspect, depends on one’s preference and tolerance for the treble. While there is definite brightness from this peak, it doesn’t put the IEM in the ‘Bright IEM’ category. It’s still a warm IEM, with some brightness showing its head once in a while. Except for this peak, the treble is linear and smooth..

Dynamics / Soundstage / Separation / Imaging

One of the biggest highlights of this kit is its huge soundstage. If you have been used to IE800, the 1st second impression would be the space getting 5 times bigger. And the feeling is like being unlocked from a chamber, and every instrument seems being restored from a point of sound to a real one with 3D shape. Many IEMs in $300 have come close to match or surpass the width. But what makes this kit’s stage special is its depth. Although, there is not an abundance of air in the stage, the depth makes the stage appear more 3D. While the imaging is not pin-point precise, it has a certain realism due to the instruments in a 3D space. The abundant space allows for good instrument separation and layering. But the IEM can tend to congestion as it is warm and its speed is not the best.

Measurements

Email to service@earphonediylabs.com if you want the original measurement of your KIT – we test the Frequency Response, Cumulative Spectral Decay, Burst and Energy Decay, Impulse Response using standard IEC 711 coupler, customized sound card and ARTA software – and we can offer both snapshot or raw data file. And following are measurements we did on a test set:

How does the YANG sound?

The YANG boosts the bass and the high 5~7dB, so to make the sound character to a typical U-curve frequency response. Such a curve is very popular on commercial headphones like Beats, SONY and the typical use scenarios is for modern pop, rock and action movies. 

See the following FR curve comparison for the detailed difference between YIN and YANG. The gray curve is YIN and the red curve is YANG. You can see they actually with similar wave crests, the different is the magnitudes. 

What’re in this DIY KIT? 

The KIT includes everything you need to build the Taichi earphones.

  1. The YIN kit includes
    • 1 pair of earphone shells in ivory white
    • 2 X 10mm dynamic driver units, used by Sennheiser IE80S
    • 1 X Shure 6N OCC, silver plated cable, with 3.5mm golden plated jack, 1.2m length
    • 3 pairs of ear-tips – 2 pairs of 2-flange and 1 pair of memory foam
  2. The YANG kit includes
    • 1 pair of earphone shells in Meteorite black
    • 2 X 10mm dynamic driver units, used by Sennheiser IE80S
    • 1 X Monster iBeast 6N OFC cable, with 3.5mm golden plated jack, 1.2m length
    • 3 pairs of ear-tips – 2 pairs of 2-flange and 1 pair of memory foam

To reduce difficulty for beginners, we have already assembled the trickiest parts.

  • The driver is pre-installed in the housing
  • The anti-dust net is pre-installed
  • Sound is fine tuned, incl. adjusting driver position, apply damping materials in the front canal if necessary  

The Taichi earphone shell

The shell is built with highly durable engineering resin (same as Apple Air Pod) by high precision molds.

OK, can I assemble it now?

The entire process takes 2 hours including 1hour waiting for the glue to dry. AMA on Reddit u/earphonediylabs or contact our service account for any issue. Note in this kit, you can skip the most difficult 3 steps.

Tools you will need

You will need an ordinary soldering iron and tin, a diagonal pliers, and a slow dry glue (e.g., E8000). If you have IEC711 coupler then you are able to further understand the build, but it is not mandatory – use your ear!

Step 1 Install the driver to the housing

This is the housing and the driver. 

Taichi, Sound Isolation Sport Earphone with IE80 Dynamic Drivers

Stick the buffer ring to the driver which helps to isolate the vibration and purify the sound (You may see similar design on speakers) We use 3M product to ensure the best quality.

Apply glue around the driver and stick the drivers to the housing. Slow dry glue like E8000 is flexible after dry and can absorb harmful vibrations.

Glue the cable conduit to the shell. Here we use Ergo 5920 instant dry glue to ensure durability.

Step 2 Wiring

Wire the cable in the order as illustrated below.

Step 3 Soldering

Now solder the cable to the driver, being careful to connect the wire to the correct polarities.

Step 4 Measurement

After soldering, measure the frequency response to make sure the installation is correct. We use IEC711 coupler and ARTA software.

If everything done correctly, the left and right channel shall be well matched like this – the dynamic drivers we offering are well paired, and the variance shall be <1.5dB.
Left channel is yellow, right is blue

 

Step 4 Assembling the shell

Stick the anti-dust net to the shell and put on the cover. Thanks to the high precision, no glue needed in this step, and you just need to push a little bit hard!
