Application:
Step 1: Thanks to its miniature size, the Spy Earpiece can be tucked directly into the ear where the Spy Earpiece cannot be seen, even if you have short hair. Of course, the Spy Earpiece works wirelessly, so you don’t need to run any cable to it. Insert the battery into the earpiece and put the earpiece in your ear. You can hear a slight noise in the earpiece after the battery is inserted, but that’s okay, it means it’s ready to use. The picture shows how deep you need to insert the STANDARD earpiece and the magnetic earpiece.

Step 2: Transmission to the Spy earpiece from the mobile phone is provided by a bluetooth loop, which has significantly better and louder sound transmission than the earpieces with a conventional induction loop thanks to the built-in 5W amplifier. The bluetooth loop includes a microphone and with this black bluetooth model, an external microphone to ensure that your "friend on the phone" can hear you better. Volume can be set directly on your mobile phone or loop. The sound volume you hear in the Spy earpiece is very good and can be adjusted directly on your mobile phone or on the bluetooth loop. This model has significantly better volume than other models thanks to the built-in 5W amplifier inside the bluetooth loop.

STANDARD earpiece is easy to remove from your ear thanks to a silicone hook, unlike the magnetic earpiece that can only be pulled out using the magnetic stick included in the package. Magnetic earpiece is currently the smallest earpiece in the world, so you don"t need to worry about being exposed. You do not need any batteries for this handset as the sound is generated by vibrations that are transmitted directly to the eardrum. The STANDARD earpiece is known as the best and most popular invisible spy handset in value for money. It is very popular because it has many advantages such as a sensitive coil receiver, a stable micro speaker, good construction, clearer audio output and a long battery life. The invisible earpiece has an anatomical shape to prevent sound leakage from the ear to the surroundings. Nobody will even notice that you wear it in your ear. The color of the micro earpiece is in full body (light) color for maximum elimination or body color, but with a black end. Included are 2 pieces of 337 batteries. Battery life in this spy earpiece is 5-6 hours.
