On the front of the monitor housing is the stylish faceplate in red color. The faceplate is available in 5 different colors which are red, blue, purple, black and green.  Here is also an action button and a small microphone opening.

On the top of the action buttons are letters with led indicators. The left monitor has the B letter while the right monitor has the V letter on the top.

The buttons are easy to operate and supporting some actions like play/pause, next track, etc.

The main part of the monitor shell is also made of plastic in black color and has a soft rubber coating. Here are also the connectors (charging ports) which are helping to charge the monitors inside the Caring Case and an ear guide for a better fixation to your ear auricle (outer ear).

When you open the case you will see the seat for the Wireless Monitors and a three LED light dots that lighting up when you put the Monitors in to the seats or if you connect it o the charger.

These seats have a magnetic surface to ensure the right connection for the charging process and to avoid any drop out of the Monitors.

The Sound:

Please note that the TFZ B.V2 is not an IEM for critical listening of your Hi-Res collection, but the overall sound and the way it’s represented is quite pleasant for a True Wireless IEM in the sub 50 USD price category.


Bass /Midrange/Treble:

The TFZ B.V2 has some strong and powerful subbass presentation that shows a pretty good depth and rumble. The subbass of the B.V2 has an average speed and control, while the quantity has satisfy me on the go.

The midbass region sounds pretty controlled and has good impact, but is missing a little bit of extension, which is quite acceptable for a True Wireless IEM especially at this price level. The midbass extension is on a moderate level and is adding the overall presentation a nice warmish tonality without to overshadow the midrange clarity, which is a remarkable plus point for the TFZ B.V2.

The midrange of the TFZ B.V2 is fairly musical and warmish in its tonality, while the level of clarity is pretty good for a True Wireless In-Ear Monitor in this price category. The level of detail is on an average level but quite acceptable when I have listened to some complex songs like Alboran Trio’s – Cinque Lunghissimi Minuti.

Both male and female vocals sounding quite pleasant with the TFZ B.V2, while male vocals sounding slightly better due to the lower midrange tuning. But don’t get me wrong female vocals like Hannah Reid or Laura Pergolizzi are represented in a quite emotional way.

The upper midrange of the TFZ B.V2 is fairly detailed, controlled and transparent. The extension is on an average level while I didn’t have heard any remarkable sibilance or harshness.

The treble range of the TFZ B.V2 shows a warmish and smooth character. It sounds a bit recessed and doesn’t show any negative situations like sharpness or hissing and offers a fatigue free listening experience with almost any track I have listened with it.

The lower treble range sounds slightly more pronounced than the upper treble area and shows in general a shorter extension. When it comes to the level of clarity, transparency and airiness I can say that it’s on an average level.



The soundstage of the TFZ B.V2 is not super expansive but is showing a sufficient performance for the use on the go. The soundstage of the B.V2 has an average width, while it shows slightly more depth.




The TFZ B.V2 is a pretty musical and entertaining sounding TW IEM with good battery life, Bluetooth 5.0 support, IPX5 certification and an affordable price that makes it to a very good True Wireless IEM option in the sub 100 USD price category.



Pros & Cons: 
  • + Musical Midrange & Entertaining Bass Performance
  • + Battery Life & Ergonomics
  • + Price to Performance Ratio
  • – Only AAC and SBC support
