4. Package and Accessories:

The TFZ TEQUILA1 comes in a small, black card box and includes the following contents;

  • 1 pair TFZ TEQUILA1 IEM

Inside the box is a white hard case with a Pelican style look. The case is big enough to store the earphone it self and some silicone ear tips for on the go.


They are 3 pairs of silicone ear tips with a small and 3 pairs with a wide bore. TFZ also included 1 pair of soft foam ear tips. The tips are comfy and don’t fatigue after long listening periods. The only con could be the transparent-white color of the material that could get yellowish after sometime.

The IEM comes with a cable that has 2 pin connectors.


5. Specifications:

a) Driver:

Inside the TFZ TEQUILA1 is a Dual-magnetic two-way Graphene driver with a relative small outer diameter of 8.9mm. The magnet of the driver is made of NdFeB N50, the voice coil of copper clad aluminum wire and the diaphragm of Graphene material.

b) Cable:

The TFZ TEQUILA1 comes with a nice looking 4 braided 5N OFC (Oxygen free Copper) cable that has 0,78mm 2pin connectors. The cable is sturdy and has low to non microphonics.



The stylish looking y-splitter and the chin slider are made of a relative heavy metal material that has a silver color.


The straight plug is also made of this silver colored metal and has 3.5mm gold plated TRS connector.

7. Design, Fit and Build Quality:

The monitor of the TFZ TEQUILA1 has a different look than traditional Hi-Fi level IEM’s. The housing is an all-metal aluminum CNC process shell and that has a quite small shell.


The TEQUILA1 has two different front cover (looks like a grill) designs; one has the look of a spider web and the other reminds me to the radioactive symbol and to the umbrella logo of of the umbrella company in the movies of Resident Evil, LOL. They are also many color options like red, blue, green etc. for each style.


The housing and the 0,78mm 2pin female connectors are very well made and it sits quite comfortable in my ears due the relative small size.


The noise isolation of the TFZ TEQUILA1 is above average.

10. The Sound:

This review is written after a burn-in process of apprx.160 hours. After some experience with some other monitors with Graphene driver, I have come to the conclusion that it needs more burn –in den regular PET drivers. I have used the stock silicone ear tips with the wider bore.

The TFZ TEQUILA1 is an IEM with a slightly V shaped sound signature with emphasis on the top and low end.



The sub bass of the TFZ TEQUILA1 between the 30 – 50Hz frequencies has the right amount of weight without to be exaggerated. The extension of sub bass notes is great an there is plenty of depth with quite good accuracy.

The speed of the double dynamic graphene driver inside the TEQUILA1 is quite fast, so that it is possible and able to produce fast bass notes. Bass notes between 60 – 250 Hz have fast attacks and decays so that it is possible so hear some nice kick drum and bass notes.

The sound signature of the TEQUILA1 is V shaped, but the midrange is only slightly recessed so that there is a nice sense of space and some airiness without to be sounding too distant.

Vocals and Instruments benefits from this tuning and the overall vocal and instrument presentation sounds in many situations quite natural, moreover male and female vocals sounding pretty emotional.

For example; Laura Pergolizzi’s voice sounds quite intimate, just like the voice of George Michael in its epic album “Older”.

Thanks to the good bass tuning, the TEQUILA1 sounds by no way muddy and it doesn’t exist any bass bleed that could be caused by the mid-bass area.

The treble range of the TFZ TEQUILA1 is prominent due the V shaped sound signature, but there is no treble harshness or sibilance unless a track was recorded in that bad way.

The upper treble range sounds crisp and tight and the clarity and detail retrieval is quite good for an in-ear monitor with dynamic drivers in this price range.

The treble speed of the TFZ TEQUILA1 excels very well in some complex tracks like GoGo Penguin’s – Muration that makes a good impression for an sub 200 USD IEM.



The TFZ TEQUILA1 sounds pretty specious and has an above average soundstage performance. There is a nice out of the head presentation in Yosi Horikawa’s track “Bubbles”. The staging is pretty wide with a sufficient presentation of depth and the positioning of vocals and instruments is quite accurate.

11. Comparison:

Vs. Whizzer A15 Pro (125 USD):

The Whizzer A15 Pro is one of my favorite IEM’s in the sub 150 USD price category.

Design, Fit & Build Quality:
It has a nice packaging and is well made. Both IEM’s are relative small IEM’s and have an above average isolation. The A15Pro is a small IEM but is not as comfy due the weight and the design choice. The TEQUILA1 is de better choice if you want listen to music for longer than 2-3 hours.

Both IEM’s have cable upgrade ability’s. The TEQUILA1 has 2 pin (0.78mm) connectors, while Whizzer decided to use MMCX ones. This is my personal choice, but I think IEM’s and cables with 2 pin connectors are more durable and safe to use and to upgrade/change.

The sound of this IEM’s is quite different. The Whizzer A15Pro has a colder and brighter sound presentation with more linear frequency response. The TEQUILA1 in the other hand sounds more musical and with its V shaped sound signature.

The Whizzer A15 Pro is missing some bass weight that makes it not as conventional as the TEQUILA1. TFZ TEQUILA1 has the better tuning for a wide variety of music genres. The bass of the TEQUILA1 has better weight and response than the A15 Pro.

The midrange performance of both is quite good, but the A15 PRO sounds a little bit too dry vs. the more emotional and intimate vocal presentation, especially for female vocals. The Instrument separation on both is quite good in the price range of between 120 – 140 USD.

The treble definition and resolution for both IEM’s is good but the TEQUILA1 has the upper hand for the control and overall accuracy. The A15 Pro has also some minor problems like upper treble harshness in some genres like metal music. Some instruments like cymbals and bells do sound a little bit ear-piercing in some of my test tracks like Lazarus A.D. – The Onslaught. The TEQUILA1 sounds more controlled and softened at the upper treble register.

The TEQUILA1 has the better depth, while the soundstage wideness of both IEM’s is nearly equal.

Vs. MEE audio Pinnacle P1 (199 USD):

The MEE audio Pinnacle P1 is one of my favorite IEM’s in the 200USD price range.

Design, Fit & Build Quality:
The Pinnacle P1 is a very capable IEM with its single dynamic driver. It has a die-cast zinc alloy housings and replaceable cables with MMCX (micro-coaxial) connectors and fits nice in my ears. The downside of the shell is that it is relative heavy that makes it uncomfortable after some hours.

The TEQUILA1 has a double dynamic driver configuration with 2pin (0,78mm) detachable cables and a full metal housing that is very comfy even after 2-3 hours.

The Pinnacle P1 has a impedance of 50ohm versus 20ohm for TEQUILA1; this means that the P1 needs more juice to show its true potential. The TEQUILA1 in the other hand is very easy to driver and sounds also good with mobile phones and tablets.

The TFZ TEQUILA1 has more sub-bass extension, depth and quantity than the Pinnacle P1 that you can hear and feel. The bass on both IEM’s is fast and shares similarities in body, pressure and weight. The Pinnacle P1 has only a hint more mid-bass extension.

The midrange of both IEM’s sounds airy and has enough space for vocal and Instruments. The overall resolution goes to the TFZ TEQUILA1 that has little bit better micro detail reproduction and sounds more dynamic than the Pinnacle P1. The upper midrange on the Pinnacle P1 sounds a bit too dry and also thin compared to the more energetic and fairly controlled sounding TEQUILA1.

The treble range on both IEM’s sounds crisp and transparent with a nice amount of detail. The Pinnacle P1 has little bit more treble emphasis on the top end that makes it prone for treble harshness.

The soundstage on both IEM’s is above average and there is better depth for the TEQUILA1, while the Pinnacle P1 has the wider staging.


12. Conclusion:

The TFZ TEQUILA1 is an eye-catching IEM with its fashionable style. The build quality and fit is one of the best in this price category and the overall sound performance is pretty good for the price with its V shaped sound signature that gives it a musical presentation.

13. Summary (plus and minus):

+ Eye-catching fashion styling
+ Good sound performance for the price
+ Replaceable cable option
+ Good build quality
+ Great Price to Performance Ratio

– Not for people who prefer a neutral tuning
