The first thing that will strike you is the size of these monsters. They are huge! And they can only be worn in the over the ear fashion. The earphones have a memory wire that will help you keep them in place. Having said that, they are not the most comfortable earphones ever, it will take some practice and getting used to before you feel at ease with them.
The build quality is outstanding. They are built like a tank. A hard resin casing that feels like it could take a beating.
The cable is strong and detachable, meaning that if it were to break, you can replace it without having to throw the whole unit out.
Sound. Here is where this puppies shine. 
These earphones are designed to give you a relatively flat response. This allows vocals and details to shine through, specially on acoustic tracks. That’s not to say that you can’t listen to electronic music with them, but to appreciate the quality of these earphones you want to listen to something with dynamic range.
The ATH-IM70 will give you undistorted highs which never become sibilant, warm and smooth mids, and punchy, well controlled bass that doesn’t muddle the rest of the music.
The soundstage is pretty open for earphones and the separation is pretty good too, better than other at this price.
If these earphones were more comfortable, they would’ve been perfect. Still, the sound is magnificent, even to the point where I feel like I’ve been listening to music wrong my entire life

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.

Following are measurements of IM70 published by, a credible 3rd party.

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 and soldering

Wire the cable in the order as illustrated below. 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 upper and under covers together.

And done! Eventually you get these nice IEMs like the original one
