Qualcomm QCC3040 bluetooth Audio SoC is a new generation of Qualcomm’s main control chip that supports Bluetooth 5.2. It has been greatly optimized in terms of connection speed, connection stability and power consumption. It also supports Qualcomm aptX Adaptive codec technology to connect to mobile phones. Intelligent switching between high-definition sound quality and low-latency modes has recently been adopted by many new TWS earbuds.
The Haylou MoriPods true wireless bluetooth earphones to be teardown today is priced at $30, which may be the lowest-priced true wireless earphones on the market that uses Qualcomm’s QCC3040 bluetooth audio SoC. The earphones adopts a semi-in-ear design, a built-in 12mm sound unit, and supports multiple audio encodings of aptX/AAC/SBC; a single earphones has two microphones to accurately pick up the sound, and the Qualcomm cVc8.0 call noise reduction algorithm can improve the voice call Clarity.
Haylou MoriPods have a colorful design. The matte shell collides with the shiny shell, which looks fresh and fashionable; the earphones can be used for about 6 hours when it is fully charged, and the total battery life is about 24 hours with the charging case. Let’s take a look at the detailed disassembly of 52audio.
Haylou is an audio brand under Dongguan Liesheng Electronic Technology. It is the first batch of Xiaomi ecological chain enterprises.

All components of Haylou MoriPods true wireless bluetooth earphones.
The charging case of Haylou MoriPods true wireless bluetooth earphones is relatively flat, with a silver decoration on the side. The earphones adopts a handle-shaped semi-in-ear style. The two processes of matte and bright surface collide. The overall design is simpler, lighter, and the earphones is slightly larger. .
In terms of internal circuits, the charging case inputs power through the USB Type-C interface, and the input is protected by a resettable fuse and TVS. The linear charging IC charges the built-in battery, and the LPS LP6260 boost IC is responsible for boosting the battery output to charge the earphones. The circuit is streamlined to ensure basic safety protection; the soft pack battery used has a capacity of 310mAh.
In the earphones part, Haylou MoriPods uses Qualcomm QCC3040 bluetooth audio SoC, which is also the biggest selling point of this product. QCC3040 supports bluetooth 5.2 and supports Qualcomm aptX™ Adaptive codec technology. It is a popular chip at the moment; and the earphone also uses dual microphones. The call noise reduction solution, and the EVE button battery, support touch operation, and the earphones material is better.
