The humble aux cable or, more formally, the 3.5mm auxiliary cable, has long been a universal standard for analog audio signals. Aux cables allow you to accomplish such tasks as plugging in your favorite set of wired headphones or connecting your smartphone or media player to a set of speakers or your car stereo system. But not all aux cables end with the standard 3.5mm jack either; some may sport a lightning connector for seamless use with iPhone devices or RCA plugs for home theater systems.

The best overall aux cable: Syncwire 3.5mm Nylon Braided
Why should you buy it? Syncwire provides a durable nylon braided 3.5mm aux cable that offers an excellent all-around solution for anyone needing to connect two devices with audio jacks.
Who’s it for? Anyone seeking an auxiliary cable to connect two devices with standard 3.5mm audio jacks and doesn’t want to worry about long-term durability.
Why we picked the Syncwire aux cable:
Most individuals looking to a purchase an auxiliary cable will want the standard 3.5mm to 3.5mm audio connector option; that’s when each end terminates in a headphone jack-style connector. This option from Syncwire not only provides this standard connection but does so at a fantastic price while sporting durability features. Unlike some cheaper alternatives, which may use only common TPE (thermoplastic elastomer) jacket coverings — you know the ones, they tend to fray after only a few months — Syncwire wraps its cable in a nylon woven jacket for increased strength.
In addition to the cable being 10x more durable than a standard cable, the end connector is made from aluminum, while the plug is gold-plated to prevent corrosion. Perfect for use with stereo systems, smartphones with a headphone jack, and media players, the Syncwire Nylon Braided Aux Cable comes in 1-meter and 2-meter variations.

The high-quality design in the AmazonBasics aux cable features a dual shielding, polished metal connector with corrosion-resistant gold-plated plugs.

Why we picked the DuKabel Top Series RCA aux cable:
When selecting an aux cable for your home theater setup, you’ll want something that doesn’t require an adapter; as most receivers sport RCA connectors and most media players use 3.5mm connectors, this is the perfect union. The DuKabel Top Series RCA aux cable is a durable option thanks to its nylon-braided exterior, secure-fit design, and metal housing.
