108B Mini Hidden Spy Earphone Short Wireless Earpiece Headset/Wireless in-Ear Earpiece with Microphone/Covert Communication Receiver

The VKBAND 108B Mini Wireless Earpiece is an ultra-small inductive earpiece designed primarily for discreet voice communication. It receives audio through electromagnetic induction from the included loopset, allowing the earpiece itself to remain extremely small and unobtrusive. It is suitable for voice prompts, presentations, stage communication, guided communication, and other situations where a conventional visible headset may be impractical. Important Audio Characteristics – Please Read Before Purchase This is a miniature inductive communication earpiece, not a conventional Bluetooth stereo music earphone. Because of its extremely small 5 x 7 x 10 mm receiver and inductive audio design, its sound characteristics are different from full-size earphones or standard Bluetooth headsets. The earpiece is designed primarily for speech and voice communication rather than high-fidelity music playback. The perceived volume may be lower than that of conventional full-size or in-ear Bluetooth earphones. A faint background sound or low-level noise may be noticeable, especially in very quiet environments or when no voice/audio signal is present. Audio clarity and volume can also vary depending on earpiece position, ear fit, surrounding electrical interference, mobile device, adapter, and source volume. If you require loud volume, strong bass, stereo sound, or high-fidelity music performance, this miniature earpiece may not be suitable for your needs. How to Use 1. Install the 337/SR416SW battery into the earpiece and make sure the battery and earpiece cover are properly seated. 2. Insert the earpiece gently into the ear canal and adjust its position for the clearest sound. 3. Connect the inductive loopset to your mobile device through the 3.5mm audio jack, or use the appropriate Lightning or USB-C adapter. 4. Wear the inductive loop around your neck and keep it reasonably close to the earpiece. 5. Start a call or play voice audio, then adjust the volume on your mobile device as needed. Specifications Earpiece Size: 5 x 7 x 10 mm Earpiece Weight: 0.8 g Shape: Anatomical Receiver Type: Magnetic / Inductive Analog Receiver Battery Model: SR416SW / 337 Battery Life: Approximately 6-8 hours Cable Length: 120 cm Package Contents 1 x Mini Earpiece 1 x Inductive Loopset 2 x 337 / SR416SW Batteries (Non-Rechargeable) 1 x Lightning to 3.5mm Adapter 1 x USB-C to 3.5mm Adapter Important Notes 1. For phones without a 3.5mm audio jack, use the included adapter or another compatible audio adapter. Adapter compatibility can vary between phone models, and an incompatible adapter may result in no sound, low volume, microphone problems, or call-function issues. 2. For best performance, keep the inductive loop close to the earpiece and keep the system away from strong sources of electromagnetic interference such as computers, speakers, televisions, power adapters, and other electrical equipment. 3. Because this product prioritizes extremely small size and discreet voice communication, its volume, frequency response, and background noise level should not be compared directly with conventional Bluetooth music earphones or full-size headsets. 4. If the earpiece does not produce sound, first check the battery orientation, battery condition, earpiece cover/contact, loopset connection, adapter compatibility, and mobile-device volume before determining that the product is defective.
