3.5mm AUX Audio Cable

Most 3.5mm AUX audio cables have two things in common: they don’t last long and they are ugly. Many people have experienced an auxiliary cable going bad and only playing music out of one speaker, if at all.

"MOS Spring cables are reinforced six ways from Sunday."

MOS Spring Warranty

The MOS Spring takes the humble 3.5mm cable to a whole new level of design and quality. The spring features only the best materials to ensure this would be the only 3.5mm cable you will ever need to buy. We’re so sure of this that we are offering a lifetime warranty on every MOS Spring AUX cable we sell.

Spring Cables


MOS Spring Features

Anodized aluminum heads not only give added protection to the conductor, it also gives the Spring a classy, high quality look and feel.

Metal spring strain relief protects the most vulnerable part of the cable. It also ensures the cable will work great with the MOS and the MOS Menos.

The Heavy Duty Braided Cable keeps the conductor protected from any abuse.

If your MOS Spring AUX cable fails for any reason, just send it back and we'll give you a new one, no questions asked.

The MOS Spring AUX cable comes in three different color choices to match your personality.

Surprisingly Excellent

Pros: -Lifetime Warranty -Really Cheap -Braided -Thin -Durable -Sleek -Precisely machined

Cons: -Braid eventually starts fraying (especially near the ends) -Paint is wearing out a little -Thinner than I expected

Other: I didn't think a cable could be this good for $6, and especially not one with a lifetime warranty - not that I've ever had to use it, because I've been using this cable for over a year daily and it still hasn't failed in any way. In comparison, I've had about 8-10 Monoprice cables in the past (most of which have broken within 6 months, but also similarly have a lifetime warranty), and various other generic Amazon brands (Belkin, Anker, etc.) and none of them have withstood as much of a beating as much as this one has. The tolerances are great, too - many of my aux cable devices (namely, my Samsung S6, which has an extremely picky 3.5mm port) won't hold in most jacks snugly, but will accept this MOS one without fail. The cable also hasn't failed on one side or anything ever, and doesn't even harden that much in -20C Canadian weather. Overall, out of all the cables I've tried (and believe me, I've tried a lot), it's pretty much the best one - I hope any replacements or I order with the lifetime warranty are of similar quality, as well.

Pros: Very thin flexible cord, not bulky at all. Very high quality aluminum. Very solid lock-up/connection with both my iPhone and UE boom. The sound is superb! Saving on battery life in comparison to using Bluetooth.

Cons: The spring stretches. My young daughter grabbed the spring to pull the cord out of the UE boom and permanently stretched the spring 2". Which is too bad. Other then that it has been great

Other: Would recommend it to others.

Pros: it works! ha. but seriously, its simple & straight to the point. also, particularly liked that in fit with different phone case-houses.

Cons: the color varied slightly from the image (in my opinion.) but it wasn't anything to dislike or be upset about.

Other: thanks, Swell. you guys are doing great things. keep up the good work!

Best value for the money

Returns when you need them are a breeze. Spring ends keep everything from damage Great quality cable. If it’s damaged and you return it once you basically paid for the cable. That took four years.

So good!

So far, pretty durable. I've only had it for about a month but i honestly love it. It's super skinny and durable and I like that it has the spring on the ends of it to protect it from the normal wear and tear that happens with cords.
