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.
