1. Size: Diameter of 2.5 millimeters, suitable for small devices.
2. Structure: There are usually three pole (stereo) or four pole (stereo and microphone) designs.
3. Usage: Suitable for connecting headphones, microphones, and some audio adapters.

advantage:
Space saving: Suitable for lightweight devices, saving internal layout space.
Portability: Suitable for devices that require frequent movement, making it easy to carry around.

Application scenarios:
walkie-talkie
Wireless headset
Portable music player
Certain models of smartphones
When using the 2.5 headphone jack, users need to ensure that compatible headphones and plugs are selected to achieve the best sound quality and user experience.


2.5 Earphone socket, typically used for certain audio devices such as walkie talkies, portable recording devices, or certain mobile phones and headphones, has the following characteristics:

1. Compact size: The 2.5mm plug and socket are smaller than the common 3.5mm headphone plug, making them more suitable for compact devices.

2. Mono and Bi channel: The 2.5mm plug can achieve mono (TS) and bi channel (TRS) audio connections, and some models also support a plug with a microphone (TRRS).

3. Durability: Due to its use in professional equipment, 2.5 headphone sockets are typically designed to be more robust and able to withstand heavier usage environments.

4. Specificity: The compatibility between the two is limited. Usually, 2.5mm headphone sockets are not compatible with 3.5mm plugs, and users need to ensure that the headphone and device interfaces are consistent.

5. Sound quality: Although smaller in size, the sound quality performance is not inferior to larger sockets, mainly depending on the audio equipment used and the headphones themselves.

6. Applicable scenarios: Widely used in professional and consumer electronic products such as walkie talkies, car audio systems, Bluetooth adapters, etc.

Understanding these characteristics can help in selecting suitable headphones and devices.
