Description

Introduction 

This is Mini Piano, an Earphones DIY Kit characterized by the grand sound stage. The kit includes 2 dynamic drivers from Sennheiser IE80S, pure copper golden plated shell and silver plated 5N OFC cable. By having basic soldering and gluing skills and the state of art components offered by us, you can easily make your own audiophile-grade earphone in 1~2 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, giving you a complete pair of Mini Piano Earphones for a bargain price. No assembly needed.

The name “mini piano” is inspired by the Final Audio Pianoforte earphone. 

How does the Mini Piano kit sound?

The IE80S Dynamic Drivers make the build very much like the original IE80S – we measured and observed 95%+ similarity in the Frequency Response with the original earbuds delivered by the manufacturers.  And due to the acoustic character of the copper shell, the kit offers even bigger sound stage than the original IE80S. 

Dynamic Drivers from Sennheiser IE80S

Want to know more about dynamic drivers of Sennheiser IE80S? See the official video from Sennheiser. 

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. 

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.

Known limitations

It’s a common issue for all IEMs using micro drivers being picky to ear-tips. And the result is you have to find one perfectly fitting your ear canal, otherwise the low bass would be seriously impaired.

The good news is we solve it for you and for free! We include following 2 pairs of ear-tips in the kit after measuring tens of different models:

  • 2-flange Silicon ear-tips (black, mid size) which doubles the sealing than normal ear-tips – made in Germany and adopted by Sennheiser IEMs

  • Memory foam ear-tips (black, mid size) made in Germany – super noise cancellation and airtight, gives you the best performance 

How can I assure I get what is advertised in this kit?

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.

Frequency Response

What’re in this DIY KIT? 

The KIT includes everything you need to build the Mini Piano earphone.

  1. 1 pair of gold plated copper earphone shell 
  2. 2 X 10mm dynamic driver units, used by Sennheiser IE80S
  3. 1 X 5N OFC silver plated cable with mic controller, with 3.5mm golden plated jack, 1.2m length, brown color 
  4. 2 pairs of ear-tips – one 2-flange and one middle size 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 Mini Piano earphone shell

The shell is built with pure copper and coated with 24K gold. As the original Final Audio Pianoforte, the shell is half-open design with 3 tiny apertures to increase bass performance and sound transparency.

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

We recommend and use E8000/B7000 or other slow dry glues. These are easy to find in any hardware store.

Apply some glue around the driver and stick the drivers to the housing

 

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.

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

Step 4 Assembling the shell

Stick the anti-dust net to the shell and glue the front and back covers. Note, do not apply too much glue, the precision of the shell is high and the covers could be easily sealed. 

 

And done! Eventually you get these nice IEMs.

How if I have special requirements?

Please leave your requirements in the ordering note and we’ll handle them accordingly, or contact our service account for any issue.
