About Unique Melody

Below is quoted from Lieven’s UM reviews:

According to Unique Melody, they are one of the first and longest-established manufacturers of custom in-ear monitors in China. Since 2007, with over 10 years of research and experience in the industry, they’ve developed a wide range of products from multi-BA, hybrid dynamic and BA, to more recent units containing Bluetooth, planar magnetic, piezoelectric, and bone-conducting technologies that also contain various patents.

About 3DT

The new 3D “Terminator” from Unique Melody is a very assertive IEM. If you wonder why it’s simple. It has 3 dynamic drivers in it. Yes, 3, and no BA drivers whatsoever.

Dual Compound Diaphragms Drivers for Bass (7mm+7mm) plus 10mm CNT Driver for Mids and Treble. We brought the authentic dynamic bass along with stunning transparency and clarity.

So here it is. A 3 dynamic driver IEM which I’ve never tried before, and I’m not sure there’s any configuration like this in the market. Let me know if you have other examples in the comments below.

And that’s not it. The new 3DT comes in with a relatively affordable price of 399 $. This was the release price but now it has come down to 319$. I’ve had good experiences with affordable dynamic driver C/IEMs, such as the LEAR LCM-Skyline. So this is a competitive price range and we’ll see how the performance goes below.

There’s one more thing though. The Unique Melody 3DT comes with a custom design from UM which is a combination of stabilized wood and resin. The design is very exclusive and the inside of the IEM is 3D printed to eliminate any distortion. So those 3 dynamic drivers sit tight in there and they have independent sound tubes and independent tunings. These are very good features for this price range.

The 3DT has a very satisfactory unboxing experience. The box is very simple but when you open the lid you’re greeted with that excellent carrying case. It’s like a zippered bag but it’s authentic and very cool. The design of the carrying case matters and that’s exactly what UM has done with this one. It matters when you see it because it’s like no other.

The case has small compartments for each earpiece so you protect them nicely from scratches and other possible damage. Since the design is very exclusive and flashy, you would want to retain its condition like new. So the case in my opinion is very thoughtful.

You have 4 pairs of tips and one of them is white but it’s not so different. There’s also a cleaning cloth which is a nice addition. More companies started to include this cloth for keeping your IEMs in a good shape so that’s nice of UM as well.

Design & Build

The 3DT looks fantastic. It’s simple as that. UM has nicely differentiated itself from the crowd with this design route, and I say that worked perfectly. The combination of blue and brown make this IEM look excellent and very premium. The shells also look very polished and shiny. I don’t have anything else to say about the design, it’s awesome.

The build quality is excellent as well, and it’s just like how we’re accustomed to UM. The nozzles are metallic, the 2-pin sockets are sturdy, and the cable itself is also very nice in that regard. It’s an SPC cable by the way, and the white color goes well with the light brown color.


I had issues with the fit at first with the supplied tips, so I started looking around my house to find the best tips for myself. This is of course very subjective for every person, but I somehow couldn’t achieve the best fit. Maybe it’s because of the memory wire of the cable which I don’t really like in these IEM cables, or maybe it’s just because of the IEM’s shape.

After I switched to SpinFit tips, the fit became excellent for me and the IEMs are very very comfortable. As usual, this shows the importance of tip rolling. Always try different tips if you’re not happy about the fitting of your IEMs. Once I found out that the SpinFit tips work perfectly, I’ve never looked back. But the shape of the IEM is very ear-friendly and not really different from many IEMs in the market.

The isolation is wonderful for a dynamic-driver setup, and it might be the best I’ve tried in that respect. Normally, dynamic driver IEMs are not isolation monsters because of the ports, but UM 3DT is a very nice experience in terms of isolation. Again, just find the best tips for you and you’re good.

A keen audiophile and hobby photographer, Berkhan is after absolute perfection. Whether it is a full-frame camera or a custom in-ear, his standpoint persists. He tries to keep his photography enthusiasm at the same level as audio. Sometimes photography wins, sometimes his love for music takes over and he puts that camera aside. Simplistic expressions of sound in his reviews are the way to go for him. He enjoys a fine single malt along with his favourite Jazz recordings.
