How This Earpiece Kit Is Usually Used
The BT01 kit is made for short, clear voice guidance where a normal headset would be too visible. The user inserts the nano earpiece, pairs the external microphone transmitter with a mobile phone, and keeps the microphone unit in a pocket, sleeve, bag, or another permitted position close to the speaker.
- Guided training and rehearsal sessions where the wearer needs a private cue.
- Stage, retail, or event staff coordination where a visible headset is not preferred.
- Specialist audio resale, sample demonstration, and OEM accessory supply.
- Security and inspection teams that need a compact communication accessory under approved working rules.
Connection, Audio, and Battery
The external microphone transmitter connects to a mobile phone by Bluetooth and sends voice audio to the small in-ear receiver. The microphone box is compact enough for clothing or pocket placement, while the 38 dB microphone sensitivity supports close-range speech pickup when the unit is positioned correctly.
| Part | Details | What to check before order |
|---|---|---|
| Nano earpiece | 6 mm in-ear receiver, about 2.5 hours working time | Confirm whether your order needs extra earpiece batteries for longer use. |
| External microphone transmitter | 35 x 25 x 8 mm compact box with Bluetooth phone connection | Confirm the final transmitter runtime for the selected batch before quotation. |
| Microphone pickup | 38 dB sensitivity | Test microphone position during sample review, especially with thick clothing. |
| Wireless range | About 7 m in normal use; about 20 m in open space | Range varies with walls, body position, phone model, and local interference. |

BT01 Compared with Common Audio Options
| Option | Best for | Limit |
|---|---|---|
| BT01 micro Bluetooth earpiece kit | Permitted discreet voice guidance with a very small in-ear receiver and external microphone. | Short earpiece runtime; extra batteries are useful for longer sessions. |
| Ordinary Bluetooth earbud | Daily calls, music, and normal visible communication. | Easy to notice and not suitable when the buyer needs a minimal receiver. |
| Wired in-ear monitor | Stage or audio work where cable routing is acceptable. | Visible cable and less convenient for pocket-based mobile phone connection. |
| Two-way radio headset | Team communication with push-to-talk and longer field use. | Larger equipment, more visible headset, and different licensing or channel requirements. |
