Disclaimer: I bought this IEM at my own expense and am not affliated to any company.
Hi this is my 3rd review on this forum.
Out of the box, my initial impressions were not very favourable, I found the bass over boomy and the mids recessed, with some harsh treble, but having burnt it in and listened more extensively, I am really really loving this IEM. So in the future, I have learnt not to make any firm impressions of any audio gear till more extensive listening.
The TFZ No. 3 is quite a fun set that will appeal to bassheads (like me).
Specifications:
- Driver: 11.4mm Double magnetism, double cavity, double voice coil, tesla magnetic group
- Diaphragm: Diamond diaphragm
- Frequency Response: 5Hz-40000Hz
- Impedence: 20ohms
- Sensitivity:108dB
- Cable: 0.78mm 2 pin detachable cable
Build:
It is made of plastic, but is extremely light.
The stock cable is detachable and quite thick and of good quality with no microphonics. I tried a few different cables, such as the NICEHCK 8 braided cable, but decided to stick with the stock one in the end, due to the sound signature and fit. The stock cable has no chin clinch though.
Apparently some Headfiers have fedback that the cable connector is similar to some other TFZ models, and certain aftermarket cables may not fit the TFZ No. 3. You can still use a standard 2 pin cable but it sticks out of the IEM somewhat. (From what I know KZ para C type cables will not fit the TFZ No. 3, more info can be obtained from the forums on which cables won't fit the TFZ No. 3).
It comes with many stock tips and after tip rolling a bit, I still found the stock ones to still suit me better.
Isolation/comfort:
These are one of the more comfortable IEMs I have ever used. I can wear it for hours with no issues. It is extremely light and ergonomic.
The isolation is also excellent. I have used it in the subway or crowded areas with above average isolation. I did not find any driver flex on it.
Sound:
This IEM is easily drivable from smart phones, and doesn't really need any amping. I tested this with a desktop -> Khadas Tone board -> Fiio A3 and android -> Tempotec Sonata HD. There is a hiss with smartphones/PC but this resolves when the music is playing. The hiss can be fixed with a simple inline volume controller, impedance mismatch device, or even a DAC or AMP.
My initial impressions was that this was a V shaped tuning, but after extensive listening, it is more of a U shape, with mildly recessed lower mids (and boosted bass and slightly boosted lower treble/higher mids).
For a single DD set up, the imaging, instrument separation, clarity and details are very good. Most of the details in the music can still be heard, but IMHO as a single DD Driver, it loses out to some other multi BA drivers in this area. Among the pure DD setups I own, it is one of the better ones in the area of technicalities.
Bass:
Excellent bass (midbass and subbass) quantities. Subbass extends very well with great quantity, and will be suitable for bassheads. The timbre is spot on and has a decay typical of DD bass. It has a midbass bleed, but some may prefer this for an added warmth in the lower registers. It may be on the slightly bloated side in terms of quality. The bass is the most emphasized of the entire frequency spectrum, but I never found it overpowering other frequencies so far (having said that I'm a basshead). The bass is definitely my most favourite aspect of this IEM and it is just one level short of jaw rattling bass.
Mids:
It has slightly recessed lower mids, but a boost in the higher mids. As such, male voices sound softer than female ones to me. Vocals and instrument tonality/timbre is superb and make me feel like I am listening to singing from the first row of a stage. The upper mids can occasionally get fatiguing with longer listening sessions with female vocals.
Treble:
Lower treble is slightly boosted. I find sometimes horn and trumpet instruments may sound a bit harsh as there is a treble peak on the TFZ No. 3 at around the 8kHZ region. Otherwise the rest of the treble is non fatiguing, with minimal silibance. There is a slight roll off in the higher frequencies, so maybe treble heads may not appreciate it. But nevertheless, most of the details are there.
Soundstage:
Average.
Conclusions:
I initially wasn't impressed with TFZ No.3 out of the box, but after listening for almost a week, it has steadily grown on me and I love it now. The excellent bass and comfortable fit, and fun sounding signature make this a keeper set for me. The upper mids/lower treble can get occasionally fatiguing with longer listening sessions, but otherwise bassheads will like it for the great sub and midbass.
