The Raspberry Pi 4 has a 3.5mm headphone jack for connecting speakers or headphones, or breaking out to another audio connector format for your own project needs. The connector also offers a coaxial video out for when HDMI isn't suitable.
We have a range of Raspberry Pi 3.5mm audio cables including 3.5mm extensions, RCA breakouts and Phono options to cover all Raspberry Pi projects.
We also stock USB audio adaptors for those looking for a better quality output. Be sure to also check out our Raspberry Pi Audio HAT section for the best possible quality audio on a Raspberry Pi!
