What is a 3.5 mm Audio Cable for?
You are likely to have used an aux (auxiliary cord) or 3.5 mm audio cable to connect your older smartphone to your car’s stereo system. This article will help you determine if these connectors can be interchanged and headphone adapters that may work best for you.
Are the AUX connectors and the headphone jacks alike? The headphone jack and aux connector are usually constructed in the same dimensions: 3.5mm (1/8″) TRS. The “auxiliary connector”, which is used for audio, is universal, while the headphone jack is intended for headphones. You can also find different sizes and wiring patterns for your headphone jack.
What is a 3.5 mm Headphone Jack?
The name of a headphone connector is the connection used to send audio signals from headphones. The male connection at the end the headphone cable is called the headphone plug. Headphone jacks usually have an output impedance lower than 24 O. However, the 32 O standard has become more popular.
The signal coming from a headphone socket is sometimes not strong enough for professional high-impedance headphones. A headphone amplifier will often be required in this situation to boost the voltage, and bridge the impedance of the audio source (now called the amp) and high-impedance headphones.
What cable gives best sound quality?
Put another way, you may be wondering Which cable is best for audio? The best cable to but to optimize your sound quality will depend on the device, music quality, cord type, and a bevy of other considerations. It is important to know there are different types of headphone jacks to consider. In fact, you can find a wide range of headphones jacks, which are classified by their diameters. The sizes of the jacks are:
- 5mm (3/32”)
- 5mm (1/8”)
- 35mm (1/4”)
How do I know if I have 3.5 mm jack?
The 3.5mm jack has a diameter of almost 50 percent more than the 2.5mm, but they are similar otherwise. A smaller connection with a 2.5 mm diameter may also have an extra ring.
Are all 3.5 mm cables the same?
The short answer is no, not all 3.5 mm cables are not the same. Cables can vary from manufacturer to manufacturer and between different applications. Tips, rings, and sleeves are standardized between 3.5mm cables and aux outputs but the quality of materials may be vastly different which may yield substantial differences in sound quality and tonality. A TRS 3.5mm jack and aux cord is most often set up like the following:
- Ring: right channel audio
- Tip: left channel audio
- Sleeve: common ground
What are the Part of a 3.5 mm Jack?
Headphone jacks have tip, ring and sleeves connections (often referred as poles). Each pole is a separate connection that carries audio signals. The number of poles can vary the design of headphone jacks. They include:
- TS (tip sleeve).
- TRS (tip ring-sleeve
- TRRS (tip-ring-ring-sleeve)
- TRRRS (tip-ring-ring-ring-sleeve)
The 3.5mm TRRS headphone jack is most commonly used (think older smartphones, tablets, and laptops). Although the jack supports TRRS, it can be used with TRS or TS plugs.
What does a 3.5 mm jack look like?
The 3.5mm connector is also used for auxiliary audio connections. These are often found in automobile audio systems, mixing consoles, as well as other consumer products.
You will find 3.5mm headphones jacks on portable audio players such as laptops, smartphones and tablets. TRS 3-pole 3,5mm connectors are the most common connectors for headphones. TRRS 4-pole3.5mm connectors can be found on headphones with microphones.
Although 3.5mm plugs typically measure 14mm in length they can also be as long as 17mm. These are still considered standard. In video applications, 15mm and17mm are common. 17mm is rare. Headphone jacks for 3.5mm headphones can be used to accept plugs of 15mm and 17mm.
What are 3.5 mm cables most commonly used for?

As its name suggests, the analog 3.5 mm headphone jack transmits analog audio signal to the attached headphones or other audio accessories. The host device (e.g. a smartphone) must integrate digital-to analog conversion (DAC), and amplifier circuitry.
Is 3.5 mm the Same as Aux?
The similarities between aux and headphone plugs/jacks are their aesthetic, size, wiring, and aesthetic. This is why they are so frequently confused. The output of a smartphone’s or laptop’s headphones is the same as the auxiliary input to a car stereo.
As we have already mentioned, the auxiliary input was designed to be a universal plug that accepts a variety of audio sources. Most compatible seems to be the 3.5mm TRS plug.
The most common headphone jacks are the 3.5mm TRS and 3.5mm RRS, although they come in a variety of sizes and wiring. An easy male-to–male 3.5mm TRS/TRRS “aux-cord” will connect most consumer-audio devices to an aux-input. Aux inputs accept audio signals at different voltages and impedances.
Is 3.5 mm same as TRS?
You should note that TRS, TRRS or TRRRS standards can be used in different ways.
Are there different types of 3.5 mm cables?
- TRS, also known as stereo mini, is the most commonly used type of 3.5mm connector. TRS stands as “Tip, Ring, and Sleeve.”
- TS(aka mono-mini) plugs have a tip and a sleeves for the ground.
- TRRS— The tip represents the left channel, while the first ring represents the right. The second ring represents the ground and the sleeves represent a microphone channel.
If you are looking for 3.5mm adapters or cables, be sure to match the plugs with the jacks. The different types of 3.5 mm jacks are used for different applications and varying product types.
Pictograms are unlikely to be seen on cell phones with headphone sockets. Don’t fret. They work with both TRS plugs and TRRS plugs. A TRS connection can be used with a cell telephone to connect to the TRS headphones. However, stereo music will still work.
Is 3.5 mm the same size as TRS
Consumer electronics devices like digital cameras, camcorders and portable DVD players use connectors of 3.5 mm for audio output and composite video. A TRS connection can be used to connect mono unbalanced audio and video, while a TRRS connection can be used for stereo unbalanced sound plus video.

Conclusion: 3.5 mm Cable and 3.5 mm Audio Jack
It is important to know the potential issues when purchasing 3.5mm stereo cables. These cables have small connectors that can break. These connectors are made using copper and gold-plated barrels that have different sizes. You can jam a component into the receiving plug of a device you are trying to connect if it is not in place. You should always check the 3.5mm connector before you insert it into any device. You can easily wear the wire, which can lead to audio distortions, or even failure.
If you make sure that your cable meets the highest standards, you can avoid most problems with 3.5mm stereo headphones. The ideal cable should be 99.99% oxygen-free copper wire.
A low loss 95 percent spiral-wound copper shield should be included in the cable. It should have a 26 AWG gauge as well as a stranded copper center conductor. For increased cable life, nickel or gold plated connectors offer better corrosion protection. They are also more resistant to damage and wear due to their fully-molded construction.
FAQ 3.5 mm Audio Cable:
Can I use a Headphone Jack as Line Out?
Headphone outputs and line inputs are quite different. However, headphones can sometimes drive line level inputs which can be used to receive line level signals. The main difference between line and headphones is their impedance. The primary difference is in the impedance you will notice. The line level inputs will typically have a 10 kΩ to 50 kΩ impedance. Likewise, you can expect 75 to 600 Ω source (line output) impedance while headphones have 8 Ω to 500 Ω impedance and range of 0.1 Ω to 50 Ω source.
