• Typical use:
▪︎ stereo headset with mono microphone
▪︎ video with stereo audio
• Contacts: 4
• TRRS plugs can transmit unbalanced stereo signals like TRS, but have an additional conductor that usually transmits microphone audio. However, this extra conductor’s position in the line-up varies depending on whether it follows the Cellular Telecommunications and Internet Association (CTIA) or Open Mobile Terminal Platform (OMTP) standards. For instance, the CTIA format transmits left and right audio channels through the tip and first ring. The second ring then acts as the ground, while the sleeve handles the mic signal. This format is common on semi-recent smartphones with headphone jacks, mobile devices, and gaming consoles. Like CTIA, the OMTP format sends audio signals through the tip and first ring. However, the conductors for the ground and mic are flipped around. This format is prevalent among older phone models.
