Hello, the main difference between Huawei FreeBuds 4 and 4e chips is that the chips run differently. FreeBuds 4 adopts the Kirin A1 chip independently developed by Huawei, while FreeBuds 4e adopts the QCC3040 chip of Qualcomm. The Kirin A1 chip uses low-power Bluetooth 5.2 technology to support dual-channel transmission, with faster connection speeds and more stable signal transmission.
It also supports Huawei's self-developed dynamic noise reduction technology and high-definition voice calling technology.
The QCC3040 chip is also a low-power Bluetooth 5.2 chip with a transmission range of up to 30 meters and longer battery life.
It also supports high-definition audio and noise suppression technology, but does not support Huawei's own dynamic noise reduction technology.
The biggest difference between the two headphones is the chip: the freebuds4 is equipped with the Kirin A1 chip, and the 4E is equipped with the Hengxuan 2500 chip.
The appearance and functional experience of these two models are roughly the same, we can regard 4E as a shrunking version of 4, the shrunking part includes:
The 2 and 4 are available in wireless and wired versions, while the 4E only has wired charges.
