Disclaimer:
Good morning, readers! With the taste of the excellent Tiandirenhe Se846 still in my ears, I decided that it was time to also try the latest releases, namely the Tiandirenhe TD08 Pro, which has a decidedly more premium and solid appearance.
The first model I tried was very similar to the EPZ Q5, though not identical. From there, the brand gained interest in my eyes.
This time we have a much better technical sheet and some extra information and graphics on the product page on Aliexpress.
Tech Specs:
- Model: TD08 Pro “Odin”
- Interface: 0.78 QDC
- Driver: 10mm(biofilm)
- Impedance: 16Ω
- Material: Resin combined with copper shell
- Panel: Odin panel
- Sensitivity: 108dB
- Frequency Response Range: 20~20KHz
- Cable length: 1.2 meters (graphene core)
- T H D:<1% @ 1KHz
Packaging:
Having already a sufficient amount of cables at home, I opted for the cable-free version. The packaging does not exist, they arrive directly in the mail envelope. Its box is the hard case included in the price. Included, we have:
- Hard case branded Tiandirehne
- Tips, even of 3 different types: A complete set of 3 pairs, 1 pair in foam and one with double flange
- 3 interchangeable nozzle filters
- Cable (optional)
Honestly, for the price paid, the equipment embarrasses much more expensive and professionally packaged products.
Design/Build quality:
Aesthetically and qualitatively, the step forward compared to the other model is notable. The resin shell has faceplates that vaguely resemble PULA IEM models. Its finish is excellent and conveys a feeling of solidity compared to the SE846, which is a simple ABS shell. The metal nozzle vaguely reminds me of the one seen on the Hidizs MS5, and the same thing with the filters that I will test later in the review. Instead, the transparent resin shell reveals the internal driver, a type of DD I have never personally seen before. A 10mm dynamic driver with a biofilm membrane is completely encased in a metal enclosure. Kind of like a bullet IEM cast inside a resin shell. Furthermore, there also seems to be some sort of tubing that connects it to the nozzle.
A technical solution and a very particular DD, the typology suggests an attempt to increase the low frequency response, and honestly, if there wasn’t a ventilation hole near the nozzle, I think they would be Bassheed IEMS.
Initial sound impression:
The Tiandirehne TD08 Pro has been with me for a while now, but I haven’t found the time to complete a review yet. At first listen, I wasn’t particularly surprised, as with the SE846, but after about an hour, my opinion changed. These are V-shaped headphones with a marked low frequency response, accentuated sub-bass, recessed mids that still manage not to be overshadowed, while the highs are quite lively, and on some tracks they become a little sharp but can still be considered safe. Guaranteed fun, the acid finish of the fronts goes perfectly with EDM traces, which these IEMs are fond of.
Comfort & Fit:
Very ergonomic design, these Tiandirenhe TD08 Pro use a decidedly tested and comfortable shape. In my case, I paired them with Tangzu Sancai wide bore tips, and the comfort is excellent. There was no discomfort, even after several hours.
Equipment used for testing the above:
Device:
- OSX
- Redmi Note 7 Poco M4 Pro
Software:
- Amazon music UHD 24bit 96kHz
- Spotify
DAC:
- Moondrop Dawn Pro
- Fosi SK02 (most used)
- Fiio KA11
- Fiio KA17
- Fosi DS2
- Simgot Dew4x
- EPZ TP20 Pro
- Hidizs S9 Pro Plus
- EPZ TP50
- Creative SoundBlaster X5
Nozzle Filters:
There is no guide that tells you what the filters do, so without measuring tools, I will just tell us what I see and hear. On an auditory level, what I heard when changing the filters and the brightness of the treble varied. I asked the seller, but the answer didn’t fully convince me compared to what my ears heard. Measurements would be needed to see the changes.
- Black (just a metal grille): The most basic (standard) filter you can use; it limits no range and thus returns the driver’s full potential. Even if some of the trebles are a little hot.
- Red (metal grille + extra thin fabric): The red filter has a small fabric membrane, which is very thin but slightly attenuates the high peaks. Depending on what you decide to listen to, this could be the best solution for multiple musical genres. The representation is slightly more fluid. The best filter.
- Blu (metal grille + thicker black fabric): The most filtered of all; the difference is not huge, but it is certainly the most suitable one if you want to further cut the highs, but in my opinion, the lows are also affected.
The red filter is the best middle ground, but I want to point out that the modding possibilities are high. If none of the filters work for you, you can always tinker with the filters by doing more tests.
Tips Rolling?
The standard supply of tips is more than sufficient, but in my opinion, wide-bore tips can improve sound performance. I honestly haven’t done much tip rolling. I had some Tangzu Sancai Wide Bore Tips on my desk, and I fitted them practically immediately. Those included are definitely many and of different types; I would like to see this variety on even more expensive IEMs. In case trebles are a little too much for you, foam tips are for you.
Bass
Some Tiandirenhe IEMs were literally just bass, then finally they added ventilation holes, and the drivers started to breathe, and the tuning became more pleasant. These undoubtedly have high bass, and above all, the sub-bass extends well, good speed and texture. They do not invade other frequencies and cover them. They can be considered bassheads approved, they are not extreme, but the quantity seems appropriate to the category.
Mids
The mids are recessed compared to the rest but not excessively so as to be covered or hidden; in the mix, they still manage to emerge with a fair fidelity and tonality. We are faced with warm and pleasant mids that do not disappoint on both male and female voices.
Treble
Being V-shaped, the highs have a good extension, sometimes on some tracks, you can hear some harshness, but between tips and filters, you can reach excellent compromises and attenuate the peaks. The presence of details is very good; airiness is present but limited; let’s say that the low frequencies “consume” a good part of the air.
Soundstage & image:
In this section, it doesn’t particularly excel, but I must say that it does particularly well. The soundstage is not large except for some details that are actually positioned outside the ear, but despite this, the directionality of the sounds and the separation are very good. In terms of image, everything is quite clear, and I honestly have no complaints about what I’m hearing. It’s a fun set, and you’re not looking for precision. It’s not the best but not the worst, especially considering the price.
Conclusion:
The price difference compared to the Se846 is around 10 USD, which is, in my opinion, a figure consistent with the difference in quality of the shell. I cannot seriously compare them, as they have two totally different targets. These are not copies of any EPZ; we can get a little closer to the tuning of the Kefine Delci but not to their final result. But if you have vacant cables that you don’t use, you can get them for 33 USD.
I don’t think I can extend this review further with comparisons. We are in the Bassheads section, like Kefine Delci and EPZxTipsy Star One, but IEMs with a full-bodied low-frequency response.
In this price range, there is honestly very little that I don’t like about these IEMs.
