The sound quality of Bluetooth headphones is determined by the following factors:
1. Version of Bluetooth technology: The version of Bluetooth technology directly affects the stability and speed of audio transmission. With the continuous upgrading of Bluetooth technology, new versions of Bluetooth headphones usually have better sound quality performance, such as Bluetooth 5.0 which can support higher transmission speeds and lower latency.
2. Bluetooth encoding and decoding technology: The sound quality performance of Bluetooth headphones is also related to the encoding and decoding technology used. For example, headphones that support aptX or AAC encoding and decoding usually have better sound quality than headphones that only support SBC encoding and decoding.
3. Chip and amplifier of Bluetooth earphones: The built-in chip and amplifier circuit of Bluetooth earphones are one of the key factors affecting sound quality. High quality chips and amplifiers can amplify and process audio signals better, resulting in higher quality audio.
4. Audio driver unit: The audio driver unit is the part responsible for sound output in Bluetooth headphones, and its quality and structure also affect the sound quality. Generally speaking, large size, high sensitivity, and low distortion audio driver units typically produce better sound effects.
5. Transmission quality: In addition to the earphones themselves, the sound quality performance of Bluetooth earphones is also related to the transmission quality. The transmission links such as chargers, charging cables, and mobile phone batteries may all affect the sound quality performance of Bluetooth earphones. Therefore, choosing high-quality chargers and data cables can ensure stable current and improve sound quality performance.
