For the nit-pickers and nerdy ones here, I’m giving the specs and technical sheets. For all the others, you can just go to the next page to see how the T4 performs.
Carbon Coated Driver
If visually the TinHifi T4 looks a lot like the T2/T3, the inner components are vastly different.
Where the T2 uses a dual-driver configuration (1x6mm DD + 1x10mm DD) and the T3 a hybrid configuration (1x Balanced Driver + 1x10mm DD, the T4 only use one dynamic driver. But, this one is made of carbon nanotube for more stiffness and better sound accuracy. Like the Diamond Coated Driver, you have in the iBasso IT01S for example.
This is also easier to tune than the previous dual driver system and the T4 should sound more like the TinHifi P1 than the T2/T3. At least on paper.
The sensitivity is fairly low for a dynamic IEM (102dB/mW) but the low impedance (32Ohms) should not be an issue for any of the actual DAPs, or even smartphones. Without the previous push/pull configuration, the distortion remains around 1% across the whole frequency range.
Like the P1, the TinHifi T4 are good noise-blockers.
Sure there are better options, especially if you lean toward acrylic-made IEMs, but I tried worse models too. Metallic enclosures can be hit or miss, and sometimes the shell can amplify high or low frequencies, which is not what we want.
As usual, the foam tips give the best results, properly stopping unwanted noises. Even if the TinHifi T4 has got small vents, this was not an issue and the IEMs muffled the conversation hum, coming from my daily commute.
Silicon tips also gave good results, but not as good as the foam. My best choice remain the SpinFit tips, even if the provided white one doesn’t fall short.
