The LEXIN G2P is a Bluetooth Intercom Headset designed for motorcycle riders, offering a range of communication and entertainment features. It is compliant with Bluetooth Specification V5.3 and supports Headset Profile (HSP), Hands-Free Profile (HFP), and Advanced Audio Distribution Profile (A2DP), ensuring broad compatibility with various Bluetooth devices.

Function Description:

The G2P headset provides a comprehensive set of functions for riders. It supports Bluetooth 5.3 for stable and efficient wireless connectivity. Users can connect the device to GPS navigation systems for turn-by-turn directions, and it integrates with Siri and other voice assistants for hands-free control. The headset features USB-C quick charge for convenient and fast power replenishment. For entertainment, it allows users to play music, and for communication, it supports hands-free calling.

One of the key features of the G2P is its universal pairing capability, allowing it to connect with most Bluetooth intercom headsets on the market. It supports Bluetooth pairing for up to six devices for two-way intercom conferences, enabling group communication among riders. The two-way Bluetooth intercom headset function allows for conversations with a distance of up to 1.2 kilometers. To ensure clear communication, the G2P has built-in CVC/DSP noise reduction technology, which intelligently minimizes background noise.

Important Technical Specifications:

The G2P is equipped with a high-definition 36MM stereo headset, designed to deliver clear audio quality. It also features an outstanding built-in CVC/DSP intelligent noise reduction microphone, crucial for effective communication in noisy riding environments. These design choices make the headset suitable for most open-face, full-face, and off-road helmets.

Powering the device is an 800 mAh battery. This battery capacity provides impressive endurance, offering up to 18 hours of music playback or 13 hours of intercom conference time. In standby mode, the device can last for over one week. Charging the G2P is done via a USB-C port and takes approximately 2.5 hours for a full charge using any DC 5V power supply (e.g., mobile phone charger, computer, laptop, or power bank). The LED indicator turns red during charging and blue when fully charged. The device also provides battery life prompts, reporting levels at 100%, 80%, 50%, 25%, and LOW. When the battery capacity drops below 25%, the device will issue notifications every 15 minutes, indicating approximately 1-1.5 hours of remaining operation before it automatically turns off.

Usage Features:

Installation: The G2P offers two mounting options for helmets: a clip mounting bracket and a 3M tape mounting bracket. The clip bracket is inserted into the helmet shell, while the 3M tape bracket adheres to the left side of the helmet, requiring 15 seconds of pressure and 24 hours to dry. LEXIN recommends using the clip mounting bracket for security. The main unit attaches to the bracket by aligning square columns on its back with square holes on the bracket and sliding it down until it clicks. To remove, the main unit is pushed towards the upper left until it slides out.

Speakers are installed by peeling off the 3M tape and sticking them into the helmet's inner padding, then pressing them firmly against velcro pads. Spacers are provided for helmets with deep ear pockets to bring speakers closer to the ears. Wires should be hidden between the helmet liner and shell. The speaker with the shorter wire is for the left ear, and the longer wire for the right, which also enhances FM radio reception. Extra speaker pads are included to adjust speaker thickness for optimal ear proximity.

Microphone installation offers a choice between a button microphone for full-face helmets and a boom microphone for open-face helmets, based on user preference. For full-face helmets, the button microphone is installed by adhering half of its velcro pad to the center of the helmet's mouth section, attaching the microphone to the velcro, and connecting it to the headphone connector from the left. For open-face helmets, the boom microphone is installed by adhering half of its velcro pad to the microphone base and the other half to the helmet underpadding. The microphone's direction is adjusted so the triangular mark points towards the mouth. A boom microphone holder can be used for additional support.

The device also features replaceable decorative shells. To replace, the old shell is pried off from a small gap on the left, and a new shell is aligned and pressed until it fits perfectly.
