However, you should remember to check if your car has slots for 3.5mm AUX or 3.0 Input for the USB extension. To mount it, you can either use an existing hole or cut a 1-inch hole and install the cable through the dashboard of your car. All accessories that you will need to do this are included in the package. Our concern with this product is that the screw to tighten does not seem very secure. Nonetheless, the other materials are, as noted, sturdy. The cables consist of durable plastic that can withstand heavy duty.

3. KEEZING Aux Adapter for iPhone

The Keezing Aux Adapter is a valuable item to have in your car if you possess an iPhone. What is even more important, is that the product is compatible with all iOS versions, including the newest ones. The connection is achievable through 3.5 male to 3.5 male audio cable, 3.5mm headphone adapter for iPhone or 3.5mm aux cord. Note that the cable does not support calls and charging functions.

With time, the effects of prolonged use will show. However, for this price, the product performs well. An essential addition to the package is the 30-day money-back guarantee and the 18-month limited warranty.

4. Oldboytech AUX Cable

But you have to make sure that they meet the 3.5mm audio port measurements. Also, the cable is made of a sturdy wire which means that it is durable and reliable.

What is more, this list does not include some of the latest iPhones like the X or 7 models. So, in this case you will have to spend more money and buy an adapter.

5. Mediabridge 3.5mm Audio Cable

Another interesting alternative on AUX car and home cable market are Mediabridge 3.5mm Stereo Audio Cable. It is a regular “male to male“ stereo AUX cable with two notable features.

One is the design of the jack which features a “step-down“ ring on the jack allowing plugs to be fully seated even when bulky protective cases are used which is very practical and needed feature since most smartphones and other devices are often in aftermarket cases causing problems with connection of jack and socket.

Another worthy feature is the construction of the cable and beneath the soft PVC material, there is a braided copper shield and aluminum foil shield.

All that with gold plated jacks guarantees clear sound and durability of the product. There is no problem with using Mediabridge 3.5mm Stereo Audio Cable with most of the popular products on the market and with the headphones since the innovative “step down“ design insures that the cable will fit anything with common 3.5 mm socket. This product is available in 4 different lengths (2,4,8 and 12 feet long) and it is a good buy with affordable price.

6. Anker 3.5mm Auxiliary Cable

The innovative technology behind Anker’s 3.5 mm AUX cable offering puts this product high on the wishlist of any in-car or home user. The 24K gold-plated jacks are standard also the “step down“ jack layout, as well as the quality materials used in construction notably the kevlar compound used in making of the cover layer of the cable.

The main advantage of kevlar is an incredible strength of the cable which is almost impossible to break and damage the copper threads inside.

The product looks and feels premium with chrome plated jack covers, gold jacks, and matte black kevlar and rubber compound cable. The price is very affordable which makes this cable one of the best connection cable offerings on the market.

The only problem is the length. It is available in only one dimension (4 feet – 1.2 meters) and while this could be just enough for in-car users it most definitely not enough for home users. The manufacturer declares the universal compatibility with all devices using regular 3.5 mm jack, but you must pay attention to the length of the “step down“ part of the jack since it could not fit the devices with extra thick protective covers.

7. iXCC 3-Ft 3.5mm Auxiliary Cable

With appealing 2-year manufacturers warranty, iXCC AUX cable looks like the premium product with interesting features for the modest price. Modern design with heavy duty connectors (metal and gold-plated) and tangle-free function are good for any in-car user because the AUX cables always get tangle-up in the car and require a valuable time to untangle it before use.

The cable itself is made from an extra thick rubber material which with big 3.5 mm jacks which fits nicely in hand during the plug-in procedure. This product also has a “step down“ feature which is good since almost all users have protective covers on their devices and longer jack is needed to fit perfectly and avoid any loss of sound.

The iXCC 3.5 mm AUX cable is available in three different lengths (3,6,10 feet) but by user experience it is safe to say that the shortest and cheapest one is to be avoided since just under 1 meter in length is just not enough for average in-car user and definitely not enough for average home user, so if you are going to choose this product we recommend you go for a longer cable option.

Buying Guide: How to Buy An Auxiliary Cable

  1. Get to know basic technology behind the product
    Best Aux CablesWe know that not everybody is the technical nerd but there are some technical things every AUX cable user should know about. First, the construction of the cable and basically AUX cable is two wires individually wrapped in protective shield undercover foil.
    But there is a difference in construction. Better cables have more insulation layers and better materials and one important feature – they are oxygen free.
    Maybe it sounds funny but a regular cable with oxygen inside is not so good since molecules of air inside of cable can cause static electricity which transfers as interference and loss of signal. So always chose an oxygen-free cable (this is the industry’s standard) which are signal-loss proof.
  2. Best materials
    Despite the fact that every cable uses the copper wires not every type of copper is the same. The better and the cleaner the compound is the better is the cable. And we are not talking just the better sound or lack of humming noises. No, we are talking security. Cables with cheaper compounds of copper are very prone to heating since the electric signals which runs through them heat the cable. Sometimes, if the cable is really bad it can even cause a meltdown and in the worst case scenario, a fire. Whenever you see that cable is hot, replace them. It is always cheaper to do that than to cover the damage. Good quality cables don’t get warm any matter how long you use them and the best materials make the best cable available.
  3. Always look for a gold jack
    Always look for cables with gold-plated jacks. If you are not audio freak it may sound strange that somebody is producing gold-plated jacks but it is a standard feature on most of the mid and upscale products. The reason is simple. The gold is the best material for transmitting an electrical impulse and far superior to iron, brass or aluminum. With gold jacks, there are no loss or disturbance in connection and they offer the best sound. Since the gold-plated jack cables are mass produced they are not expensive since the layer of gold on the jack is very thin and doesn’t add the value of the product much. All the best cables have this feature
  4. Do not search for the best deal, search for the best cord
    Don’t look at the price as the only aspect of your purchase and don’t buy the cheapest product on the market. For just a little bit more money you can have a much better AUX cable which will last you longer and be safer to use. Better and more expensive cable is always a better option since it improves the sound of the music and reduces the background noise from your car’s other electrical systems. Always buy a longer cable than you currently need. It is wise to approach since the longer cable gives you more room to maneuver in your car.
  5. Check compatibility with your device
    Always check the compatibility of the cable with your current devices. Since the 3.5 mm socket is standard it is safe to say that almost any cable will fit but sometimes you need to be extra sure since devices can have thick protective covers which will make problems if the jack is shorter. Especially pay attention to headphones if you are planning to use them.
  6. Avoid breaking your cable
    Try to keep your car AUX cables rolled up and safely stored when they are not in use. That will keep them in working order for longer and avoid breaking of the cable. If you bend the cable too much it could break the copper wire threads inside and cause loss of contact, sound interference, and heating of the cable.

This type of AUX cable has the same function as the regular one but is used if you want to connect more complicated devices which could play video files to your in-car video screens.
