UM 3D Terminator 3DT

I researched this IEM considerably before purchasing. Most reviews I could find in online magazines and forums were mixed, but the reviews on this site were overwhelmingly positive and I bought it for that reason.

I agree with the reviewers on this site. Excellent IEM that brings out the emotion in music and plays every genre well. I use it with FLAC files on a Hiby R6 2020 and bought a cheap balanced cable which was better than stock SE. I enjoy the stock tips.

Bass is tight, voices are present and connect emotionally, instruments have great timbre, great layering and soundstage. I’ve rediscovered my music library and it’s been a joy. All this has been said by others on this site and I agree with them.

It’s so good Ive been contemplating buying a spare! You can’t go wrong with this IEM.

There are surely an incredible value. Never thought you could pay so little for so much music!

with spinfit tips and pure copper cable, it became an excellent iem, having a clear v tonality, the bass has better decay and impact, the mids were advanced, the highs were reduced peaks, excellent scene, body, detail , a natural, clear, transparent sound and great instrumental separation.

Reviewing 3DT after about 24 hours of burn in. I did hear some changes in this time and with others recommend good burn in with these drivers. I listened for this impression via iFi micro iDSD signature streaming Roon. My units came new, I am giving my impression using stock cables but have used large silicone tips that came with Ikko OH10 (not Final Audio E's) that are similar to SpinFit 100+s. Stock tips did not provide a good seal for me (but I have large ears/canals). It is vital to get a good fit to capture bass on the 3Dt, otherwise you will not "get it". I found the FR to be MUCH to my liking. Bass rumble is impactful, as much as I'd want it quantity wise, and well-extended into the sub-bass, mid-bass is fast and punchy with a pleasing transition to lower mids - no bleed that I could detect. Instruments in the mids and in particular vocals (both male and female) are forward but never shouty- very smooth. Treble is similarly relaxed/smooth, never sibilant. Overall the sound is very coherent and organic across the tonality range. Imaging and layering is distinct although the space between voices and instruments is tight. Stage is correspondingly close though it does wrap around you with some sounds even projecting behind the head - like you are sitting right IN THE BAND. Attack is good on the front end but decay is a little less well-controlled, especially in the sub-bass. Instruments have great body, presence and note weight, though micro-detail retrieval is not 'what this IEM is all about' - what it is about is immersive, delicious mids and treble that soar above the impactful low end- very addictive. Once you get a good fit you will never want to take them off. Very thankful to Andrew again for making these available and another smooth purchase experience.

Was interested in the driver config and how it would sound/deal with rock and metal genres. It's a really energetic and punchy IEM that deals with metal genres very well, and also sounds very clean and clear. It's a great complimentary IEM for my modest collection.
Also need to express my thanks to Musicteck for fantastic customer service and responsiveness to my emails, and the unbelievably fast shipping from US to UK (ordered on Mon and was delivered to me on Wed).
