Unboxing & Accessories

The Series 2 comes in a rectangular silver box with a transparent film protector that sports the words “12 Months Quality Guarantee” and “The Fragrant Zither. Focus On Hifi Audio-Visual Products”. You can see the iems through the transparent film. The iems are separated from the detachable cable. At the back of the box, you get information of TFZ company in different languages and a sticker showing the colour of the iem which is black with the code “009”. After removing the transparent film protector, there are 2 boxes. The white box contains the iem and the detachable cable while in the silver box, you get 2 sets of silicon tips (S, M, L), 1 soft carrying pouch, 1 shirt clip, 1 instruction manual and 1 warranty card. I feel that the accessories are sufficient and the package contents are organized neatly.

IEM Build & Design

The Series 2 has a glossy black faceplate with the model name ““TFZ Hi-Fi Series MONITOR SERIES 2” printed on it. The shell has the same colour as the faceplate and it is made up of plastic which contributes to its light weight. There is vent near the edge of the iem and it is golden in colour while on the inside of the iem, there is a vent too. At the back of the iem, there are words printed on it. On the left, it is printed “L” while on the right, it is printed “R”. It utilises 2-pin 0.78mm extruded socket for the detachable cables. The iem is not heavy at all and coupled with the design of it, I am able to get a comfortable fit. The nozzle is slightly angled and it prevents earwax from going in with a metal mesh. Overall, I find the Series 2 to be constructed well and it is comfortable to use.

Cable Build & Design

The cable is 4 core braided. On each of the 2 pin connectors, there is a L & R marking on the outside of the left and right respectively with strain relief too. There is a memory wire area and the cable is enclosed in a transparent heat-shrink tube which is very flexible. Moving on to the y-splitter, it is circular and matte black with the TFZ logo on it. Lastly, the jack is 3.5mm gold plated with strain relief. On the housing of the jack, there are 2 small rectangular metal plates with one sporting the words “” and another one sporting just “TFZ”. There is a smooth surface to the jack housing. Overall, the cable is flexible with minimal microphonics.


Sound Analysis


The sub-bass of the Series 2 has quite a good extension to it although it is not very deep. There is a quick rumble that helps to improve the overall dynamics and the speed is impactful. I find the sub-bass to have a good tightness to it. Moving on to the mid-bass, it has a decent slam and I personally find it easy to listen too. The quantity here is just nice and appropriate if one wishes to listen for a long session. The bass has a clean presentation but lacks the visceral impact. Bass texture is rendered rather smoothly and the smoothness aids in the overall bass presentation. The bass transits to the lower mids well but with more quantity, it can be better. The bass is clean and smooth with a good extension. It certainly helps to prevent fatigue.


The Series 2 has a splendid midrange that is capable of doing both male and female vocals justice. I feel that the lower mids has a good amount of body to it and male vocals are bring presented cleanly without sounding too dense. The upper mids has a good amount of forwardness to it and this contributes to the intimacy of female vocals. The midrange is empahsised nicely and there is no compromise on both male and female vocals. I find there is a very good control in the midrange and the midrange is being presented in a mature way. The lower mids is not too thick and upper mids is not shouty. The musicality is not sacrificed for technicality. Overall, the midrange is nicely done and is able to tackle both male and female vocals.


The treble is extended nicely and I feel the extension is just nice. It is very controlled and tight. The energy from it is existent but there is a lack of sparkle for extra bite. There is no sibilance and harshness which results in an easy listen. The amount of air present is sufficient and it aids the overall sound. There is clarity and details are being expressed with ease and confidence. However, there is a lack of crisp at the top end. The treble extension is nice and coupled with the amount of air, it is very engaging to listen to. The definition is good and it needs a slight sparkle for a more immersive listen.


The Series 2 has a good amount of width and depth for the soundstage. The width is sufficient to prevent congestion of tracks and the positioning of vocals and instruments benefits as such. The depth is not too close in and there is space. The stage is really immersive.
