  • How does this earpiece work? Can the earpiece be seen from the outside?

The earpieces that work with induction technology include an inductive collar where we will connect our mobile phone via Bluetooth. This inducing collar will be placed around the neck under our clothes, being completely hidden from other people. This piece emits inductive waves that when they reach the earpiece are transformed into vibration, causing sound. Learn more.

This earpiece is 100% hidden due to its small size similar to a lentil, being totally invisible to other people.

  • Is it easy to hide the neckloop under clothing? Can it be seen?

Yes, it is simpler than it seems and with a shirt, t-shirt or polo it will be completely hidden. The induction collar cannot be seen because it will be completely hidden under clothing. Additionally, they can be used adhesive strips to stick it to the body and not move during use.

  • Can two people use the same earpiece kit? And two kits or more in the same place?

Each kit is suitable for use by one person because the induction collar transmits sound using short-range electromagnetic induction. The range is from the neck where the collar is located to the earring that is located in the left ear.

There can be several people in the same place, each with their own earpiece kit. To avoid slightly hearing what the other person is listening to, it is recommended to maintain a minimum distance of 4-5 meters. Otherwise, we will simply hear what the other person hears with their kit, but at a lower volume than ours.

  • What happens if the bluetooth is disconnected? Is the bluetooth device visible?

If the Bluetooth is disconnected from the mobile phone, the call or recording, song or other audio that is usually playing stops or is silenced. This depends on the mobile configuration. In our experience, it is extremely rare for the Bluetooth connection to be accidentally disconnected as it is such a widely used and widespread technology.

The Bluetooth device is completely hidden from others when a mobile phone is connected.

  • Is it difficult to remove the nano earpiece? It is safe?

No, the nano earpiece is really easy to remove by following the instructions with the extractor bar and the extractor magnet. In no case may it remain inside the ear.

The nano earpiece is completely safe as it does not include any internal electronic component in the headset, since it works due to the material it is made of, reacting to the inductive waves of the collar or inductive element. It has an appropriate size to ensure safety in use and introduction into the ear canal.

  • How is the nano earpiece inserted? How do we know if it is well inserted?

To introduce the nano earpiece we must tilt our head and drop the earpiece into the ear canal. Maintaining the position we must shake our head slightly until we notice that it has entered correctly.

To know if it has been correctly inserted, we must notice the sensation of a drop of water entering the ear and the clogged ear. We can check it by inserting only the extractor bar, if the earpiece is extracted it means that we have not inserted it correctly. A single earpiece in the left ear is sufficient in most cases.

  • Can I insert two earpieces in the same ear? And one in each ear?

It is advisable to only insert a earpiece in the left ear because we usually hear better than through the right ear. If it is inserted correctly with a earpiece in the left ear, it is enough.

Yes, it is possible to insert one earpiece in each ear, but when trying to insert the second one, the first one may become dislodged. Two earpieces should not be inserted in the same ear because they will not be inserted correctly and may cause sudden movements of wax.

  • Can we regulate the volume of the earpiece? Can you hear from outside?

Yes, we can regulate it through the volume of the cell phone/mp3 and the induction collar.

It is impossible to hear it from the outside because the earpiece is inside the ear and emits a very slight sound.

  • Does it incorporate a microphone?

Yes, it includes a built-in microphone to communicate using signs such as knocking or coughing.

  • Do I have to charge the earpiece?

It is not necessary to charge the earpieces because the induction collar causes vibration in the earpiece, generating the sound. The nano earpiece does not include any electrical circuit. Learn more.

  • Does it need batteries or is it battery operated? What autonomy does it have?

The inducer collar has a built-in rechargeable battery. The autonomy is approximately 4 hours depending on the volume.


  1. Turn the Nano V4 inducer collar into pairing mode by holding down the button with the phone icon for at least 8 seconds. Hold it down until the LED lights flash blue and red quickly.
  2. Search your mobile for the “T-LOOP” bluetooth device and connect it to your mobile. After connection, we can see the battery percentage of the induction collar in an icon in the notification bar or in the list of Bluetooth devices.
  3. Place the Kit on the body as indicated in the Use Diagram.
  4. Insert only one earpiece into the left ear: Turn your head 90º so that the ear where we are going to insert the earpiece is facing upwards. Next, drop the earpiece into your ear and, maintaining the same position, shake your head until you feel the earpiece enter your ear and become "plugged". It may be necessary to distribute it several times. The sensation when it enters correctly is similar to a drop of water falling through the ear canal and/or a clogged ear. If it comes out when you turn your head, it's not well inserted.
  5. Play a song on your mobile or mp3 and increase the volume to maximum on the mobile to check its operation.
  6. After use, turn off the inductor collar and remove the earpiece by repeating step 4 in reverse using the extractor bar with the extractor magnet at its base.

With the Kit you will receive the nano v4 earpiece instructions with illustrations and tips for use.

    The first time you put the earpiece in, it messes up a bit because it's a small thing but it comes with a stick to remove it, and when you see that you're approving it becomes a vice.
