The Design, Build Quality, Fit & Comfort:

The Sabbat E12 is a Wireless In-Ear Monitor with a 10mm Single Dynamic Driver unit. Each Monitor has a build in Battery + Bluetooth receiver that support the Bluetooth 5.0 standard.

The size of the monitor is pretty small and lightweight for a device with a build in battery, DAC and Amplifier, while the design has an very ergonomic shape that makes longer listening periods possible.

The monitor shell is made of plastic and has a glossy surface that is available in silver, coffee, cyan, copper, purple and red color options.

On the front of the monitor housing is Bluetooth/Power indicator and the multifunctional button which sports the Sabbat brand logo. This multifunctional button is quite responsive and supports the following actions;

Power on /off, play/pause, call answer, Siri/Google Assistant activation, next/previous track, etc.

On the top of the E12 is a small vent slot.

The sound nozzle is on the back side of the device. This nozzle is quite small in diameter and sports a fine woven metal mesh on the top to prevent the insertion of dust and earwax in to the monitor.

Here are also the connectors (charging ports) which are helping to charge the monitors inside the Caring Case, the microphone and the Left / Right markings.

The Sabbat E12 is coming with a very small and carrying/charging with a capacity of 750 mAh. This case is in black color and is made of plastic. On the backside of this case is the hinge mechanism that is in silver color and that sports the Sabbat branding.

Here is also the USB Type-C charging port and the led indicators for the charging status.

When you open the case you will see the seat for the Wireless Monitors.

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

This case supports the QI wireless charger standard and can be charged with the charging dock that is available for additional 5,00 USD.

The Sound:

The Sabbat E12 is a Wireless IEM with a V shaped sound signature that offers warmish tonality. The bass and the treble range are more pronounced than the midrange.

Please note that the Sabbat E12 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 Wireless IEM in the sub 100 USD price category.

Bass / Midrange / Treble:

The Bass quantity and intensity will satisfy many users who are looking for a wireless IEM to get in the mood while listening to genres like EDM, Trance, RnB, Pop, etc. The sub-bass rumble will satisfy many bass lovers with great rumble and full bodied presentation. The sub-bass is going pretty low and has an extension, which is on a moderate level, followed with average control and speed.

The mid-bass quantity and character give the sound a full-bodied and warm presentation, while overall bass detail is on a moderate level. The bass performance and character of the TFZ X1 is quite suitable for listening genres like EDM, Pop, Trance etc.

Instruments like guitars, drums or for example contrabass are sounding warmer and thicker than in natural.

The midrange of the Sabbat E12 has a fairly smooth and relaxing tuning with moderate transparency and a warmish tonality and didn’t shows negative situations like sharpness/harshness.

Male vocals are showing a thick and emotional tonality, while female vocals sounding lush, but lacking some transparency and sparkle. The midrange sounds fairly musical while it is missing some clearness and air. Instruments like guitars, violas or pianos sounding emotional but thicker and warmer in tonality than in natural.

When it comes to the treble range, I can say that the Sabbat E12 is showing a fatigue free presentation with average speed, extension and control, which makes it ideal for longer listening periods on the go or gym / exercising.



The soundstage performance of the Sabbat E12 is quite ok for a True Wireless Bluetooth IEM for on the go. The soundstage of the E12 soundstage has an average wideness and depth.




The Sabbat E12 is a very comfortable to wear Wireless Bluetooth IEM, which offers an entertaining music experience on the go or while exercising and has some nice futures like a IPX3 Water & Dust Proof certification and a charging case with QI Wireless Standard.



Pros & Cons: 

  • + Powerful Bass and Entertaining Presentation
  • + Great fit and comfort
  • + Charging Case supports QI Wireless Standard


  • – Midrange Clarity

    I purchased these sabbat e12. They are great for music. Bad for phone calls. The person you are talking to cannot hear you well most of the time. Also intermittently loses connection with other ear bud(not often), however reestablished connection quickly.
    I still love using them. Just dont make too many calls …

    • Gee says:

      Thanks Fred for the update. Wonder why the original reviewer never reviewed the other most important function, the call clarity, after all is a “Headset”

  2. Zack says:

    My sabbat e12 earbuds can only last for 30mins playtime..what a waste buying this brand.
    Also useless for making calls.

    • Gökhan AYDIN says:

      Hi Zack, it looks like that your E13 is defective, beacuse my E12 has a playtime of approx 5/5.5 hours. I would recommend to contact your seller.

    • Golfin_i says:

      They are either defective or not fully charged. Mine last for hours! I pop them back in the case after walks and listening to audiobooks. The clarity on phone calls is just fine. My biggest complaint is that even the large size tips fall out of my ears at times and I cannot fine the correct nozzle size to order foam tips.

  3. Mckyz says:

    I bought mine yesterday and so far, i think it’s good. Good for phone calls and for music too.

    • Mark says:

      Hey Mike, are you charging wirelessly, I’m finding it difficult to find a supplier that stocks a wireless charger which they are willing to confirm as compatible with Sabbat despite their QI rating

    Is the e12 can use L and R simultaneously?
