The compatibility issue of Bluetooth earphones mainly lies in their ability to effectively connect with other devices and perform data transmission and communication normally. At present, Bluetooth earphones on the market basically support the global Bluetooth protocol, which allows them to be paired with the vast majority of smartphones, tablets, televisions, computers, audio devices, etc.
When using Bluetooth headphones, compatibility issues may arise in the following areas:
1. Headphone connection: Some mobile phones, televisions, and other devices have lower versions of Bluetooth chips or do not support certain types of headphone connections, which may result in situations such as inability to connect or disconnection. However, this situation is relatively rare among common Bluetooth devices in the market.
2. Call: Due to different phone call protocols and Bluetooth versions, compatibility issues such as voice delay and noise may occur when answering calls or conducting voice chats.
3. Audio transmission: When playing music or watching movies, Bluetooth headphones have high requirements for audio encoding standards. If the encoding standards supported by the device and headphones are not consistent, it can lead to poor sound quality or intermittent sound.
