How many kinds of jacks are there?


Headphone jacks can be divided into the following eight types:

1、3.5 mm TRS: 3.5 mm TRS is the most common headphone jack. From top to bottom, it is left channel, right channel and grounding. It is compatible with most mobile phones and DAP.

36.3mm: The jack is a 3-segment design with left channel, right channel and ground. Due to the large area occupied, in general, it is only used on home audio equipment, which is common in two-channel amplifiers, large amps and so on.

6.3mm

44-pin XLR: Appears on a large amp or a home amp. It is a balanced jack. The left and right channels are completely separated, but the grounding is shared to achieve balanced transmission.


52.5mm TRRS: Some DAPs have balanced output jacks. The amplifier lines can be processed independently from left to right. The gain output is very sufficient, which not only makes the headphones easier to push, but also reduces the noise affected by the current, making the music clearer and more pleasant.
