Unique Melody 3D Terminator 3DT


Inner Structure

Unique Melody 3D Terminator 3DT

3D Explosive View:Tri-Dynamic Design, Concise Structure, Maximum Space Utilization.

We utilized 3D printed technology for 3DT’s inner structure. In that way, we optimized the sound transition and further reduced the unwilling distortion. Each dynamic driver equipped with an independent tunnel, each driver is tuned separately and precisely with our newest tuning technique. Ultimately the sound is much more coherent, image and synergy are also significantly improved.



MaterialSelected Stabilized Wood

Special CraftPigments and resins are mixed in a specific proportion and filled into the log.

AppearanceHas more coloration layers than traditional resin shells.

ExclusivenessExclusive design.

We applied CNC technology to design the curvy silhouette for the shells. The curve design is ergonomic, and the delicate design is close to the contour of the ear canal.



3DT utilized three dynamic drivers: 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. With this driver combination, we provide the classic dynamic flavor with enhanced technical performance to the audience. The sound signature leans towards relaxing and refined with uplifting treble and ultra-highs.

Affordable but not Cheap

I don’t want to use the word “cheap” on 3DT, but it is truly affordable—the most affordable IEMs from UM, period. At $399 you will get much more than what the price indicated. Every 3DT is fully handcrafted by our experienced crafters.

Besides the fantastic sound quality and build quality, we also provided a very useful accessory package.

Just like our other products, we equipped a great Italian PU leather case made by Dignis for 3DT. We added a premium SPC cable in this package too.

Great at what they are

These IEMs are great at what they are at the price, which is a dynamic sound, good tonal balance and thick dynamic mid-range which is great for metal guitar crunch, yet they remain versatile for other genres. I'd rather listen to these than anything I have below or at this price-point. It gets beat by some of the newer popular mid-tier tri-brids for detail retrieval and end-to-end frequency extension, but these are quite a bit more fun and dynamic for an engaging listen versus a sometimes flat sound in mid-tier tri-brids. These are a great compliment to those to have some variety in your listening options.

Edit: Using these with an 50-75 ohm impedance adapter transforms these adding punchy low end, maintains the great mids and softens a bit of the top end. They're good without too, but really fun with an adapter. These are in my daily rotation for some straight dynamic fun.

Fantastic B2 Competitors

Not sure why there isn't more love for these little gems. They sound terrific with accurate timbre from the all-DD construction. The biggest difference between these and other IEMs I've tried is that these sound as though you are truly experiencing the music, rather than just listening to it. Despite the bass-leaning FR curve, I found that I've had to tweak up the sub-100Hz frequencies a dB or two to match my sound preferences. Aside from that, the 3DTs are sonically excellent, clarity is well above average, and the soundstage is broad. I'd consider these to be the benchmark in this price range. Couldn't be happier.

Detail, separation, and clarity

Provides unusual degree of presence, like sitting close to a live performance. Great instrument detail and separation, with clarity and lovely timbre in highs, mids, and lows. Male and female vocals sound great, with mild sibilance in some female vocals. Beautiful IEMs.

Goldilocks IEM

Great all-rounder! Outstanding timbre and tonality, great technicalities, if it only had a bit more air and sparkle at the very top it would be TOTL no doubt.

Incredible value for money!

This is my second purchase from MusicTeck - the first being the recently released UM MEST Mkii. Both orders arrived in the UK within 72hours of dispatch (which Andrew typically manages same day)! Absolutely wonderful service that can't be faulted.

Having recently brought the MEST MKii which has its own unique (excuse the pun) sound signature that is great for various genres of music that emphasise the 'grand', I was looking for a more forward mids section and a more intimate soundstage, preferably with great timbral accuracy for acoustic / vocal, the more 'intimate' performances. I also didn't want to spend as much as I had done on the MEST Mkii (which is definitely worth the cost by the way) and wanted an IEM I could take out and about with me.

I happened upon the 3DT purely by chance in the 'sales' section of MusicTeck for a very tempting price! After a quick bit of research I found the driver type and config, frequency response and general feedback fit with exactly what I was after!

I have zero regrets with this purchase. Fit is comfortable and secure. I have swopped out the stock cable for a thicker copper cable and paired with my M8 DAP it produces some real magic. There is some strength in the upper mids / lower treble that might be grating to some, but tip changes can help with this to some degree as can appropriate source pairing. Thankfully I don't find it an issue at all with my setup.

This IEM has unbeatable timbre - it is so very life like and is simply a joy to listen to. I haven't heard quality in this price range before and I've sampled quite a few at this level.

MEST Mkii + 3DT is a wonderful complement to each other and exactly what I was looking!

Thankyou MusicTeck!
