Sabrent 3.5mm Male-to-Male Aux Cable

Sabrent 3.5mm Male-to-Male Aux Cable

Sabrent’s male-to-male aux cable is a universal fit, working with standard aux ports on all smartphones, tablets, and other audio devices. Gold plating on the contacts ensures a clear listening experience.
The gold plating works. Interference is almost completely absent, and the transfer rate is excellent. It’s also extremely long, and the universal fit really is universal—this doesn’t rattle in any device we’ve tried.
It’s expensive compared to the competition, and looks unnecessarily fancy for a simple aux cable. The tip also requires a bit of force to secure in place.

AmazonBasics Male-to-Male Stereo Audio Aux Cable

This male-to-male aux cable transmits audio files via stereo format. It pairs with any gadget with an aux-in port or a 3.5mm audio jack. Use it to connect your smartphone, tablet, or MP3 player to portable speakers or your car's stereo.
AmazonBasics gives a one-year limited warranty for the aux cable. It offers static-free reliable performance thanks to its beveled design and gold-plated plugs. These two features also ensure that there's virtually no signal loss.
The edges of the cord are not properly shielded and may carry an electrical charge. The cable is also not ideal for complex audio setups, where the audio passes through more than one source, as it may produce a hum.
Honorable Mention

FosPower Audio Aux Cable

This cable has 24k gold-plated connectors to resist corrosion and tarnish. The copper braided and aluminum foil shielding provides flexibility and reduces interference. Available lengths range from 1 to 25 feet.
The cable produces a nice clean sound with an excellent sound quality transfer. It's sturdy, thick, well-made, and it fits directly into your phone with the case on.
The cable may come loose, and over time it may only work when it's positioned in a certain way. It may break or start crackling after a short period of use.

Benefits of Aux Cables

  • Listen on the go. If you have a playlist or songs on your Apple, Samsung or other mobile devices that you want to listen to through your vehicle's sound system, the best aux cable for speakers will enable you to do so.
  • Ease of use. It's quite simple to play music or other audio files from your smartphone, iPad, or other electronic devices by simply connecting the best aux cord brand into the aux socket of your vehicle located in the dashboard, armrest, or glove box.
  • Portability. The best aux cable can be as small as one or three feet in length. It is easy to carry and transfer from one car to another. You can also use these cables around the home, with items such as a personal computer.

Types of Aux Cables


A 3.5mm aux cable is a standard for stereo input and output. It can be used with a compatible jack or auxiliary input to link an audio source to your vehicle's stereo system. This cable can be used with cell phones, portable MP3 players, portable navigation devices, remote mount DVD players, or other electronic devices.


An optical cable sends a raw digital signal, while a standard 3.5mm cable sends a converted analog signal. An optical cable is higher quality. A 3.5mm cable cannot be used in a fiber optic input/output, and a fiber optic cable cannot be used in a 3.5mm input/output. They each require different cables and connectors. Optical cables provide less interference but are more expensive and less common than 3.5mm cables.

Top Brands


Monster Cable Products, Inc. was founded in 1979 in San Francisco by laser-fusion design engineer/audiophile/professional drummer Noel Lee.  Lee realized that the gauge and construction of speaker wire had an enormous effect on the sound delivered. One top product is the Monster Aux Cord for Car Stereo.


Anker, based in Bellevue, Washington, was founded in 2011 by "a few ex-Googlers." The company designs technology such as wireless charging, car charging, and portable and wall chargers. Its claim to fame is delivering power "at unprecedented speeds." One popular product is the Anker 3.5mm Premium Auxiliary Audio Cable.


Mediabridge cabling and connectivity products have been around since 1998, and the company began selling products directly to consumers in 2008. The company is based in Cherry Hill, New Jersey, and strives to bring affordable technology to its customers. One top product is the Mediabridge Male To Male Stereo Audio Cable.


KabelDirekt is a family business founded in 2010 in Germany with the production of HDMI cables. Before long, it started producing various video and audio accessories to meet consumer demand. One recommended product is the KabelDirekt Pro Series Audio Aux Cord.

Aux Cable Pricing

  • Around $5: Aux cables can be very affordable, but their quality can be wide-ranging. You can find decent products in this price range, but make sure to do your research before you make a purchase to avoid inferior cords.
  • $5-$10: The best quality aux cable will typically cost you a little more money. However, you don’t need to spend a lot of money to find one that will be durable and produce a clean sound. 
  • Over $10: Some premium cables may be a little more expensive, and you can find products that work just as well for a little less money. Also, cords that are longer in length cost more.

Key Features

Gold-Plated Connectors

Most mid- and high-end products feature gold-plated connectors. The top aux cords will include this feature because it aids in sound transmission. Better connectors improve sound quality and also cut down on electronic interference. Gold plating will make a huge difference when it comes to how your music sounds in your vehicle.

Other Considerations

  • Materials: Manufacturers use various materials in their cables. Most wires are made of pure copper, but the quality of copper can differ depending on the brand. It's important that you find a product made of top-quality material. Better-made wires will transmit quality sound more efficiently and be more durable overall.
  • Oxygen-Free Design: A heavy-duty aux cable includes two wires wrapped in protective foil. Those with more layers of insulation and made of better materials will be superior because they are free of oxygen. A cable with oxygen inside may have issues with static electricity, which can cause interference or signal loss. The industry standard is oxygen-free cables.
  • Compatibility: Most electronic devices are compatible with a top-rated aux cord. They typically have a 3.5mm standard port. However, some devices may not have this type of port so you may need to use a different cable.
  • Bend Lifespan: The bend life refers to a cable's durability. What it measures is the amount of bend the cable can endure before it starts to wear. At the very least, the most durable aux cord will have a value of at least 10,000. The higher the value, the better.

Best Aux Cable Reviews & Recommendations 2020

Many male-male aux cables claim to have a universal fit, but this cable from Sabrent is the closest we’ve seen to actually backing up that claim. We’ve tried it in smartphones, mp3 players, tablets, car stereos, speaker systems, and everything else we can find that makes a pleasant noise. While some require a bit of force to snap into place, each one has ultimately fit and worked to a high standard.

There’s a lot more to recommend this product over all the others. It’s a very long cable, making it ideal for listening in the bathtub, or anywhere else in which you feel too comfortable to get up. It’s also a great choice for large group meetings, especially work conferences and church gatherings. The gold plating ensures near-zero interference, leading to unprecedented clarity of sound with a stellar transfer rate.

There are a few downsides. While the sound reminds us of high-quality headphones, the price unfortunately does too. Be prepared to pay a bit more for this cable. Also, as we mentioned, it can take some pushing to fit this cable into some older-model smartphones and tablets.

Driving to and from work every day can get boring if you have nothing to listen to. If you're looking for an aux cable that offers value for the money, this may just be it. It lets you listen to music, audiobooks, or audio files all day. Use it to connect your phone to your car's stereo and enjoy your favorite music or audio files on the go.

To get started, connect one end of the cable to the 3.5mm audio jack on your phone and the other end to the aux-in port in your speakers, headphones, car stereo, or audio output device. Gold-plated plugs on each end make for reliable performance and minimal signal loss. The gold plating also makes the aux cable resistant to corrosion. The cable has a narrow shaft and easily connects through phone and tablet cases.

But despite its many awesome features, it does have a few issues. Unlike many high-quality aux cables, its ends are not properly shielded and can carry an electrical charge. In addition, you cannot use it in situations where the audio file goes through more than one source. It will produce an unpleasant hum.

This cable features 24k gold-plated connectors to resist corrosion and reduce tarnish. The copper-braided and aluminum foil shielding provides cable flexibility and reduces undesired EMI/RFI interference. Its polyethylene foam dielectric insulator minimizes signal loss, and the tin-plated copper core reduces oxidation and increases wire life. It's available in lengths ranging from one to 25 feet.

The combination of foil and braided copper shielding helps prevent static and loss of signal, and it produces a nice, clean sound with the excellent sound quality transfer. The cable is sturdy, thick, and well-made, the ends are firmly attached, and it fits directly into your phone with the case on. The cable is nice and flexible and is easy to move around without getting tangled or kinked.

One problem is the cable may come loose every now and then. Over time, it may become position sensitive and only work when it's lined up in a certain way. The cable can break or start crackling after a short period of use. It may also fail to lock in properly on some phones, causing it to come loose during rough conditions.

Mediabridge is a well-known company that produces reliable and high-quality cables. This particular model is highly popular because of the excellent sound quality and compatibility with different devices. You can plug it in all kinds of smartphones and MP3 players, even when they have different types of cases. 

Measuring 3.5mm, the cable is compatible with almost any device, including iPods, laptops, and earbuds. Once plugged in, it enables impressive audio output without any kind of noise and vibration. 

What makes the cable even more appealing is the sturdy construction. It features gold-plated plugs that are corrosion resistant and very durable. They allow for crisp sound and reduce the chance for signal loss. Additionally, the step-down design ensures a secure connection at any time, regardless of case size and shape. 

Still, there are a few things to keep in mind with this product. The main drawback is the overall stiffness of the cable. Due to the lack of flexibility and plastic rings around metal plugs, the cable requires special handling and shouldn't be wiggled a lot for storage. Also, the plugs tend to loosen up after a while, so you might need to screw them back on from time to time.

iXCC is a widely popular brand trusted by many users. Here it delivers a well-made aux cable you can use with all kinds of devices. You can plug it into phones, iPods, tablets, and MP3 players and enjoy the quality sound when on the go. 

The cable features dual-shielding connectors made from polished metal. They are gold-plated, very durable, and suitable for daily and heavy use. The tangle-free design also makes the cable quite convenient for transportation and storage. 

The cable measures 3.5mm, which means it plugs into all standard jacks. Even more important, it ensures you get clear and crisp sound at every listening, without signal loss or annoying noises. It also provides a secure and stable connection.  

It's important to notice how thick this cable is, though. It might not fit into small ports and will require some modifications. Also, some buyers reported issues with occasional noises. The cable might produce a loud pop now and then.

If you're looking for a budget-friendly cable, this might be an excellent choice for you. StarTech offers an excellent combination of high sound quality and durability at a low price. You get to use the cable with iPods, MP3 players, and phones, without experiencing noises and other sound interferences when on the road. 

This is a 3.5mm aux cable that comes in different lengths, so you get to choose the one that suits you the most. All of them plug into the standard car jack and ensure you get excellent music experience while driving. Another great thing about this cable is the fact that it comes with molded, gold-plated connectors. They reduce the chance of losing the signal and overall prolong the life of the aux cable. 

There are, however, a couple of things you should know about this product. The cable is very thin and light, and while that allows for more versatility and easier storage, it also influences the overall durability of the product. The cable feels a little flimsy and requires careful handling. It also might not be a perfect option for heavy use.

This is another quality product from iXCC. It's an innovative aux cable that's not only well made and highly reliable, but it's also fairly priced. iXCC offers an item you can use with various devices for rocking your favorite tunes when on the road. All you need to do is to plug it into the car jack, and you're ready to go. 

The cable features 3.5mm gold-plated connectors. With dual-shielding polished metal, they are corrosion-resistant and built to last. Also, the innovative design reduces signal loss and possible noise, allowing you to enjoy quality sound from your device. 

It's also important to notice that the cable is made to fit tight spaces and withstand heavy abuse. It doesn't even tangle, so you won't have problems with transportation and storage. 

The excellent flexibility might also come as a drawback, though. Because the cable is not very thick, it's more prone to damage and might be less durable. The ends are also a tad thin, so you might need to wiggle them a little to find a proper position.

Belkin offers a quality aux cable for a hassle-free music experience when on the road. The item allows you to connect your phone, MP3 player, tablet, or any other audio device to your car stereo or speaker system. With connectors that measure 3.5mm, it's suitable for all standard jacks and is easy to use. 

The cable features a flat design, which prevents tangling and ensures easy transportation and storage. This type of design also helps with the connection, so you should be able to use it with just about every electronic device, regardless of its dimensions. 

Buyers also like the nickel-plated connectors that reduce noise and ensure excellent signal. They are very well-made and capable of withstanding heavy use. You won't even experience connectors loosening up or wiggling inside the jack. 

When it comes to drawbacks, there are a few minor ones to keep in mind with the Belkin aux cord. The first regards the overall length of the cable. It's a tad short, reaching only the driver's and front passenger's seat, so it might not be suitable for everyone. Also, some buyers find it pricey, especially considering it's not that durable.

This is a universal aux cable that measures 3.5mm and connects to most audio devices. You can use it for listening to music from your iPhone, iPad, smartphone, MP3 player, and a variety of other devices. It's also compatible with most case types, even those bulky ones that make finding a perfect aux cable quite challenging.  

Thanks to the slim, low-profile design, the cable fits perfectly and is super easy to connect. The metal housing makes it incredibly durable yet doesn't influence the overall flexibility of the cord. You'll still be able to wrap it up for transportation and storage, without causing tears or cracks. 

It's also important to mention that the cable has gold-plated connectors for more durability. They are corrosion-resistant and ensure a stable connection. Additionally, the oxygen-free copper provides maximum conductivity and reduces the chances of signal loss. 

The main drawback of this cable comes from the fact that the tip barrels tend to loosen up. You might need to screw them back on every once in a while. Also, the connectors are quite thick, so the cable might not be a perfect option for those who have thin cases with small ports.


  • When you're looking for the best cheap aux cord, quality should be a top priority. It will only cost a little bit more money to find a product that will last longer, prevent static, and reduce background noise.
  • Purchase a cable that is longer than you think you need. That way, you will have more cable to work with, and you can maneuver it better in your vehicle.
  • Avoid damaging a premium aux cable by carefully rolling it up and storing it when you're not using it. This will prolong the cable's life and keep it from breaking.
  • Don't yank the cable to remove it from your vehicle's aux port or your device. If you handle the cable in this manner, it is more likely to break down. Gently remove the plug instead.
  • There is a difference between an aux socket and USB port. The aux is for connecting your phone or media device, and an aux cable can be used for connecting headphones and other audio equipment.
  • Be careful about purchasing an off-brand product. A cheap, generic product is less likely to have the quality you need to produce decent sound and music from your device.


Q: How do I install an auxiliary cable? 

A: The single 3.5mm jack aux cable is the most common type, and you simply need to plug one end into your vehicle's aux socket and the other end into your phone or electronic device. 

Q: What is the benefit of a shielded audio cable?

A: It blocks interference. A shielded cable surrounds a signal wire and aids in reducing interference from nearby electronics and radio signals. Shielding also prevents crosstalk between cables.

Q: Will an auxiliary cord fit on a smartphone with a case? 

A: It depends on both the aux cable and the type of cover you have. Some cables feature narrow end connections that make them slimmer and easier to use with thick covers. 

Q: What length of cord do I need for use in my car? 

A: Unless you have a really large interior where everything is spaced far apart, a 3-foot cord should be adequate. However, it depends on where your aux input is located. A 6-foot cord is long, but it will be more versatile, and you can always coil up the unused portion.

Q: Does a longer cord affect performance? 

A: The length of the auxiliary cord should have no effect on the sound performance. A 3-foot cord should produce the same audio quality as a 10-foot cord.
