# Dùng loa và tai nghe khác nhau

You can use external speakers or headphones with your computer. Speakers usually either connect using a circular TRS (tip, ring, sleeve) plug or a USB.

If your speakers or headphones have a TRS plug, plug it into the appropriate socket on your computer. Most computers have two sockets: one for microphones and one for speakers. This socket is usually light green in color or is accompanied by a picture of headphones. Speakers or headphones plugged into a TRS socket are usually used by default. If not, see the instructions below for selecting the default device.

Some computers support multi-channel output for surround sound. This usually uses multiple TRS jacks, which are often color-coded. If you are unsure which plugs go in which sockets, you can test the sound output in the sound settings.

Nếu bạn có loa hoặc tai nghe USB, hoặc tai nghe analog cắm vào cạc âm thanh USB, cắm vào cổng USB. Loa USB hoạt động như thiết bị âm thanh riêng biệt, bạn có thể xác định loa nào dùng làm mặc định.
