Green Touch Chip Cooperative Brand Honors Pro-choose MOECEN Earbuds X1 True Wireless Bluetooth Headset
Honor Pro-choice is an e-commerce platform of Honor, which is mainly engaged in various smart home products and aims to create an AIoT ecological chain belonging to Honor. Recently, MOECEN’s Earbuds X1 true wireless Bluetooth headset was selected into the Honor Pro-choice Eco-Chain and went on sale through Honor’s e-commerce platform. It has received a lot of attention. Today we will take a look at it.
According to my observation on the official website of Honor Proxuan, MOECEN’s Earbuds X1 is the platform’s first third-party TWS headset product, which just fills the gap in the entry-level product of Honor headset in terms of price.
In terms of hardware configuration, Earbuds X1 supports Bluetooth V5.0, supports simultaneous transmission of both ears, and the official data game audio delay is as low as 130ms; the headset has a customized 7mm composite diaphragm moving coil unit that supports SBC and AAC audio encoding; the headset supports dual microphone calls Noise reduction function, touch support, IPX4 waterproof. The headset battery has a capacity of 55mAh, the charging box uses a Type-C charging interface, and the battery capacity is 500mAh. The overall configuration has almost no shortcomings in products at the same price. Let’s take a detailed disassembly to see which components are used in Earbuds X1~
I have previously disassembled Honor FlyPods 3 true wireless active noise reduction headphones , Honor FlyPods TWS true wireless Bluetooth headset , Honor FlyPods youth version TWS Bluetooth headset , Honor Xinqing wired headset .
1. Unpacking MOECEN Earbuds X1
The packaging box is a small white square box, and the upper left corner of the front is the brand logo selected by Honor; the rendering shows the inner and outer sides of the earphone, with a white body and an in-ear design; the name of the earphone, MOECEN True Wireless Bluetooth Earbuds X1; Features, true wireless, dual-mic call noise reduction, 24 hours long battery life, pure sound quality.
The back of the box is a detailed introduction of product features and hardware information. Product model CE79, overall size 60.3*43.2*28mm, net weight 47.1g; charging box power input 5V?410mA, output 5V?50mA, charging box battery 500mAh, headset battery 55mAh.

The contents of the box, earphones and charging box are stored separately, the charging short cable and the included silicone earplugs are individually packaged, as well as a quick start guide and a cleaning stick.
Let's first look at this more "going heart" gift, two cleaning cotton swabs.
The function of the cleaning swab is to clean the dirt on the metal contacts.
The two ends of the cotton swab are very sharp and slightly moist. Use it as soon as possible after disassembly.
The headset comes with two extra pairs of silicone earplugs, and the headset is a medium size.
The charging cable is a USB-A to USB Type-C interface with a short length.
There are three reminders for the seal on the charging box: 1. The earphone must be put into the charging box to activate for the first time; 2. Do not open and close the charging box cover frequently in daily use, for the sake of service life; 3. It is recommended to turn on the Bluetooth of the mobile phone for daily use. Take out the headset to ensure the success rate of pairing.
The surface of the charging box is polished, and the top and bottom are two flat surfaces, with a smooth transition at the edge, and there is a charging indicator on the front.
The hinge on the back of the charging box is displayed.
The Type-C charging port is located at the bottom of the charging box, and the C port can be blind plugged in front and back. It is easy to use, and it is very popular now. The charging case shell is made of polypropylene.

3. Disassembly of MOECEN Earbuds X1 headset
Let's disassemble the earphone part. The outer shell of Earbuds X1 is a flat surface that supports touch. The overall appearance is not as AirPods Pro as in the rendering; the earbud handle design is convenient for adding dual-mic call noise reduction function.
There is a pressure relief hole on the outer shell of the earphone, which is also used for noise reduction microphone to pick up ambient noise; there is a hidden indicator light next to it, which can be observed during the day.
There is a call microphone at the bottom of the headset to pick up human voices and charging contacts.
The fine dust-proof net at the sound hole can prevent foreign matter from entering the earphone.
Disassemble the earphones along the inner and outer moulding lines of the earphones, the classic strip motherboard + soft pack battery + speaker internal structure.

I love audio network summary
MOECEN Earbuds X1 true wireless bluetooth earphones, earbuds and charging box have a simple design, few openings and small size. There are two planes on the top and bottom of the charging box, and the outer cover of the earphone is also a plane, which is somewhat different from the official renderings that are too round, causing many people to misunderstand.
Earbuds X1 charging box adopts Type-C interface input power supply, and contains LPS Microsource Semiconductor LP7801D single-chip charging and discharging solution, which can step down the input current to charge the built-in battery, and boost the battery output current to earphones and other components Power supply; battery capacity 500mAh; there is a Hall element in the charging box to realize the function of opening and connecting.
In terms of earphones, there are only two microphones on the housing of the Earbuds X1 with openings, and the indicator lights are designed to be hidden. The earphone cavity is slightly larger, the earphone handle is relatively short, and the overall appearance is still very high; the interior adopts a bar shape Motherboard, in order to realize the noise reduction function of dual microphone calls; the Bluetooth main control chip is Hengxuan BES2300, which supports Bluetooth 5.0, does not distinguish between the main and auxiliary ears; the headset uses the FPC + thimble touch solution, and the Bluetooth antenna is also a patch type; inside the headset The soft pack battery has a capacity of 55mAh. There are Nanlin XT4052 linear charging IC and Saixin Micro DFN1×1 lithium battery protection IC on the motherboard.
Overall, the Earbuds X1 true wireless Bluetooth headset launched by MOECEN this time is a good entry-level TWS headset product with reasonable design and regular workmanship. A little regret is the lack of in-ear detection function, but the volume is Battery life is also a major advantage of its products at the same price.
The ability of MOECEN Earbuds X1 to enter the supply chain of Honor's selection is a win-win choice for both parties, because Honor currently has no layout in entry-level TWS products. On the other hand, Shengshi’s R&D and products have also gained well-known brands. Endorsement. If in the future Honor Pro Choice and Honor mobile phones can be further opened up in terms of software functions, AIoT products including TWS headsets will be even better for consumers' experience.
