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.
