HTML Image as link Qries

Tin HiFi the brand which is based out of China is a well established brand in the ChiFi Audio industry. The brand is specialized in making high quality in ear monitors both in the budget and high end category. Their T3 Plus, P1 and the P2 are the products that boosted the brands image due to their exceptional sound quality and to continue that legacy sound the P1 got a new upgrade the P1 Plus. In this review let’s see how this performs against the competitors and its own competitor P1!


This unit has been provided to me as a part of a review circle organised by the HiFiGo Team and a big thanks to the team for adding me in their circle. This review is completely based on my observations and based on my sources and pairings hence it might differ from person to person. I have not been influenced by the brand nor the person to manipulate this review.

The design is the same as that of the P1 but with some minor changes which are minute. Apart from the design the thing that i don’t like in this is the fit! It’s total garbage! The nozzle being very short in length they don’t get inserted into the ear canal perfectly. Even with the L sized tips they don’t provide the adequate sealing. With foam tips the isolation was able to be achieved.

The full construction is made out of metal. As Usual the Tin team went with the controversial MMCX connection this time. The cable is of good quality where its a copper coloured cable. The termination area, splitter and the connector area are made completely out of metal.  A slider is given in the cable and the cable don’t get tangled up easily.

The given case is however one of the best i have to say. The case is completely made out of leather and its handstitched. The branding is done on the top of the case. The inner surface are completely lined with nice brown coloured soft lining.


The sound of the P1 plus is more of a neutral sounding pair with upper midrange emphasis. The bass being too modest and lean while the treble issues with the cymbal crashes we will discuss about the sound in detail in this review.


The bass being a planar earphone it’s kind of disappointing for me. The P1, not the plus version, had an even better bass when amped up. The Tin Team revamped the P1 variant by giving this Plus version to sound better even without amping but the truth is the plus needs some amping to unleash the full potential. 

Even when amped up via the Zen Can the bass in the Plus seems to be too shy hence they sound very lean. The sub bass feels pretty light and the rumble is subtle to null. The extension is average in the low end. The mid bass is faster in decay providing a nice amount of clarity and separation but for some EDM and POP music this bass is too light.

The fullness and bodied sound is missing in the P1 Plus due that light low end. The faster decay of course contributed to the clarity and separation in the low end. The thump and fullness just lacks which is kind of better in the P1 non plus variant.

Tracks Used:

  1. Jungles (Instrumental ) – Tash Sultana
  2. Mountains – Hans Zimmer
  3. BigFoot – MALFNKTION


The mid range is nicely tuned here with one of the best natural tonality and timbre one can find. The presentation feels very much forward and this is kind of fatiguing for me in the long listening sessions. A slight bit of laidback presentation could have been better. The vocals of both the male and the female sound clean and detailed. The fullness is not found in the vocals due to that reduced mid bass presence.

The staging being a slight smaller in terms of width the serene appeared sight a bit of closed one. The layering however felt nice where the placement of the instruments found to be very realistic. 

The upper midrange is the slight disturbance here where they are slightly peaked up thus the female vocals sound harsh sometimes and when the high hat instruments appear the sounds become thinner and harsher. 

The separation and the detail retrieval is brought out really well and the technicalities aspect in the mid range are neatly done and overall the midrange is a very pleasing segment with natural and neutral tonality, timbre.

Tracks Used:

  1. Fi Ba7ri – Alaa Wardi
  2. Why Can’t She – Adam Craig
  3. Easy On Me – Adele


The treble is clean and crispy in the P1 Plus. The treble being extended well the airy and open sound is present in the IEM. The point where I started to dislike it is that the cymbal crashes sound a bit harsh. Their attack being very splashy they sound harsh most of the time. 

The guitar strings and the trumpets do sound brighter and clean. The airy sensation that it provides gives a nice sense of open sound. The minute details are brought up good and clean. The track separation is nice without any noticeable congestion seen. 

The brilliance factor is seen here and the shimmer is present in the top end giving nice clarity and open sound overall.

Tracks Used:

  1. Jack Of Speed – Steely Dan
  2. Dreams – Fleetwood Mac
  3. Sultans Of Swing – Dire Straits


STAGING: The staging of the P1 Plus is more on an average side since the width is not that expensive. The height is average too hence don’t expect any wide serene surroundings. They don’t sound that intimate too hence its more on a normal side but not wide when compared to the other competitors in this price range.

IMAGING AND LAYERING: These are another best aspect of this earphone. The layering is done very nicely where the placement of the instruments are more or less precisely done and the transient response of the channel from left to right is neatly done and appears smooth overall.  

Detail retrieval and the instrument separation are above average and overall this definitely triumphs in the department of technicalities.



  1. Neutral Sound Profile
  2. Tonality and Timbre
  3. Layering and Detail Retrieval
  4. Accessories


  1. Lean Bass
  2. Upper Mid Range Hotness
  3. Fit


The P1 Plus, the latest offering from the Tin HiFi is the successor of the P1. The P1 already being a very nice IEM in the price range with one of the best planar bass that one can get but the issue is they need to be amped up compulsory to unleash its full potential. To avoid this issue the Brand launched the Plus variant but the reality is their power demand is high hence an amp is needed to seek its potential.

The sound is now more on a neutral side with faster and technical bass thus the fun low end rumble cant be expected here. The mid range has natural tonality and timbre thus giving nice pleasing sound. The upper mid range has that weird peak where the female vocals sound harsh sometimes. The detail retrieval and the separation are above average. The highs are brought out really well but the cymbal crashes ofcourse sounds too splashy. The staging is kind of narrow for my taste and to compensate that the layering was done actually very good in the P1 plus. 

Overall the sound is very nice for a neutral sound lover but as a general user I would still get the P1 non plus variant since it sounded better to my ears overall. The technicalities are slightly superior to that of their older variant but misses out on the fun factor and based on my observations this is NOT THE PLUS THIS TIME.
