HONOR CHOICE is a Honor ecological brand, with HONOR Connect as the core, aiming to create a full-scene IoT ecological chain. Recently, HONOR CHOICE has launched a new true wireless noise-cancelling earphone - LCHSE X7i, which supports the HONOR Connect smart ecosystem, which can achieve Honor devices pop-up pairing when the case is opened to achieve convenient connection and view remaining power information; it also supports multi-device intelligent interconnection, and mobile phones/tablet devices with the same Honor account are free of pairing.

In terms of functional configuration, HONOR CHOICE LCHSE X7i true wireless noise-cancelling earbuds are equipped with 12.4mm titanium-plated composite diaphragm, which supports enhanced spatial surround sound and provides accurate sound field positioning and sound details; supports hybrid active noise reduction functions, including mild, moderate, deep noise reduction modes and transparent transmission modes, with a maximum noise reduction depth of 45dB; supports dual-mic AI call noise reduction, accurate voice pickup and filtering background noise, providing clear call effects.

HONOR CHOICE LCHSE X7i supports Bluetooth 5.3, supports low-latency game mode, and ensures game audio and video synchronization; supports fast switching of dual devices, touch control, and convenient use. In terms of battery life, the earphone can last up to 8 hours for a single music, and 40 hours for a comprehensive battery life with a charging case. Let's take a look at the detailed disassembly report of this product below~

The HONOR CHOICE LCHSE X7i charging case adopts an oval "pebble-shaped" design, with a paint texture, and a gray waist line is exposed in the cockpit. There is an indicator light on the front of the case to feed back the Bluetooth pairing status of the earbuds and the remaining power information.

Open the charging case cover and take out the earphones, and view the internal structure of the cockpit.

Pry open the charging case shell and take out the cockpit structure.

View of the front structure of the cockpit is provided with an iron pillar corresponding to the Hall sensor on the main board for the function of opening the lid and connecting immediately.

View of the structure on the back of the cockpit, fixed battery unit, covered with sponge pad protection.

The bottom of the cockpit is fixed to the main board by screws, the battery wires are welded to the main board, and the solder joints are glued for protection.

Remove the screws and remove all components from the bottom of the cockpit.

Disconnect the battery wire and view the circuits on the side of the main board of the charging case.

SS88E8H is a low-power microcontroller with the integrated power management function of SinhMicro, responsible for charge and discharge management of the built-in battery and control of the whole system.

The silkscreen " B2BDoEB0 " represents SSD101X programmable boost IC of SinhMicro, which is used to boost the built-in battery to charge the earbuds.

The boost inductor cooperates with the boost IC to boost the built-in battery to charge the earbuds.
