These inputs allow us to connect smartphones, mp3 players, laptops, and plenty of other devices directly into the car's audio system for playback.Īuxiliary inputs generally have an impedance of more than 10 kΩ and expect to receive a nominal voltage level of -10 dBV (0.300 V RMS). You've likely seen an aux input in a 2000's car stereo. To learn more about headphone jacks and the various types of jack and plugs, check out my article Differences Between 2.5mm, 3.5mm & 6.35mm Headphone Jacks.Īuxiliary connections are designed to connect a wide variety of devices to a single quasi-universal jack. We'll discuss these in greater detail in the section on wiring standards. Note that there are different wiring standards when it comes to TRS, TRRS and TRRRS standards. ![]() The Rupert Neve Designs RNHP (link to check the price at B&H Photo/Video) is an excellent example of a headphone amplifier with a 6.35mm (1/4″) headphone output. Headphone jacks come in a variety of sizes, described by their diameters. In this case, a headphone amplifier is often required to boost the voltage and bridge the impedance between the audio source (now the amp) and the high-impedance headphones. The signal from a headphone jack is often not strong enough to drive professional high-impedance headphones. Headphones typically have an impedance between 8 Ω to 600 Ω, with the 32 Ω standard becoming more common. Headphone jacks generally have an output impedance of less than 24 Ω. ![]() The headphone jack is the female connection (at the audio source), while the headphone plug is the male connection (at the end of the headphone cable). In this article, we'll discuss headphone jacks and auxiliary connections in more detail, focusing on their similarities as well as their differences.Īs the name suggests, a headphone jack is a connection meant to send audio signals to headphones. Headphone jacks also come in different sizes and wiring schemes. However, the “auxiliary connector” is universal for audio while the “headphone jack” is, by its name, suited for headphones. ![]() If you've ever wondered if the names of these connectors are interchangeable, this article is for you.Īre AUX (Auxiliary) connectors & headphone jacks the same? The construction of the aux connector and the headphone jack is often the same: 3.5mm (1/8″) TRS. If you've ever plugged an older smartphone or portable music player into a car stereo, you've likely used an aux (auxiliary) cord to make the connection from the device's headphone jack to the car's aux input. ![]()
