As usual, files were played from either Qobuz / Spotify or my own music library. Some tracks will be highlighted, just so you can try it at home too !
I ran across some positive feedback regarding the TinHifi T4 when I checked the Indiegogo page. And… I have to concur: these are some impressive IEMs for the price.
First, the sound stage is much wider than the previous models. On Reykjavik from Joachim Pastor, the various effects can be spotted with ease, and even the modest FiiO M5 was able to drive some serious bass out of the T4.
That’s the second big improvement you’ll hear: at least some bass ! That was my main complaint regarding the T2/T3, the lows were too shy compared to their competitors. That’s not the case with the TinHifi T4, and once you’ll get the right tips, you’ll be pleasantly rewarded with some neat, deep, lows.
The sole 10mm driver does a wonderful job. The layering is excellent and honestly, if no one tell you, you may never believe that that tiny IEM only costs a mere 100 bucks. Deep lows ? Check. Crips mids ? Check. Clean highs ? Check. With electro tracks, it’s simply night and days compared to the TinHifi T3.
There is no sibilance, even if the high-mids are a bit forward. It’s a fast IEM, with sparkling details at every level of volume, without the annoying harshness that you may find on some models. It’s very much like the T3, signature-wise, but better in every other aspect. Voices feel real, drums are deafening and everything seems to take place naturally.
Once combined with the Chord Mojo, the TinHifi T4 trades some musicality for more accuracy. It’s almost synthetic and if the P1 felt just right, the T4 began to sound like the Beyerdynamic T5 : too bright for me. The transients were too fast, too blunt, leaving me breathless after each listening session.
And that’s another quirk of the T4, they are very sensitive to the source. With the right source, they may sound like a sub 300$ IEM, with rich details, good balance, and superb musicality. But, with the “wrong” source, they will sound chemical, as one of those IEM that try too hard, and never feel right with those hard-hitting highs and falsetto mids.
Yet, once paired with the right source, they’ll truly sound amazing.
Highs : clean hit. The TinHifi are not prone to sibilance, which is great. Everything sounds really natural and the great ADSR is definitely at work here. With the FiiO Q5S and the Cowon Plenue D2, Diana Krall was astonishingly pleasant to listen.

Mediums: spaciousness and effortless. The sound stage is amazing and transients are crazy sharp, which translates to dashing mids. Jazz and vocal tracks feel just right, and once you’re seated, you’ll have a hard time leaving.

Bass: deep, fast, powerful. If I liked the TinHifi T2/T3 lows, they were nowhere near to what the T4 delivers. The bass is pinpoint, clean, deep and never overtakes the rest of the spectrum. Even when you push the volume, the T4 follows the straight line and gives you one of the best basses, in this price range.

Sensitivity / Hiss
Impedance is low, sensitivity correct. This makes the TinHifi T4 easy to drive. They are sensitive to hiss so choose your source carefully.
