Isolation is the unsung hero of great sounding audio. If your music is polluted with ambient noise it’s simply not going to sound as good as it should. In-ear headphones have a natural advantage when it comes to isolation, but because of the way the silicon tips fit into your ear canal, they’re not going to be a perfect fit every time.

The best isolation comes from custom ear molds that have a user-tailored fit so they’ll always block a ton of ambient sound. Unfortunately, custom molds are notorious for their outrageous pricing, costing upwards of $1,000 after you tally up the visits to an audiologist and the delicate materials needed for the molds. If this sounds like a golden opportunity for a manufacturer, you’d be right.

Enter newcomer Decibullz and its Contour Custom Molded Earphones (MSRP: $59.99), which first wowed us at CES 2014. Instead of spending your life savings on trips to a professional, the Contours come with twin pieces of moldable thermoplastic so you can create your own custom molds. All you need is some hot water, your ears, and about 15 minutes of your time. While the actual headphones don’t have the highest build quality, the performance is above average and the custom molds alone make them worth the price of admission.

The Look

Without the bells and whistles, there’s not much here

Without a doubt the Contour's standout feature is the custom molded thermoplastic. Take that away and you’re left with pretty standard buds that aren’t really notable for much else in the looks department. In fact, the first thing that you’ll probably notice is how small and seemingly unimpressive they are. They’re black from earbud to audio jack with small white accents like a logo on the back of the buds and a white “Decibullz” stamp on the in-line remote.

You can save hundreds of dollars on custom ear molds by buying from Decibullz.

Although in-line remotes used to be few and far between, it’s almost a given nowadays. Without it, you’ll probably feel a little cheated—like you’re missing something crucial. You don't have to worry about that with the Contours, though, which include a one-button remote. The lack of volume controls is disappointing, but while I’d rather not try to fish out my phone in a crowded subway train, it’s not a deal-breaker. The one-button remote provides all of the necessities, including the ability to skip/rewind tracks, play/pause your music, and answer phone calls.

The in-line remote is situated on a “tangle-free cable,” which means it’s the flatter variety that is a lot less likely to bunch into a knot. It’s also relatively short as far as headphone cables go, coming in at around 3.75 feet long. There's always plenty of slack when I use the Contours with my laptop or with my phone in my pocket, but if you have a full-sized desktop you might run into problems.

Boasting a "tangle-free" cable and a one-button remote, the Contours have all the comforts of quality earbuds.

If you're like me, there's only so much a "tangle-free" cable can do when you're just going to wrap your in-ears up and shove them in your pocket. Instead, you’ll almost definitely want to take advantage of the included clamshell case. While the custom molds have the feel of hard plastic, once you shape them to your ears they’ll probably have a thinner section that could potentially break if you’re careless. And while there are spare silicon tips, you’ll only get one set of thermoplastic molds in the box.

Custom Molds

“This feels weird. Warm and weird.”

As the folks over at Digital Trends can vouch for, getting liquid goo injected into your ear via an audiologist for custom molds is a painful and awkward process. Basically, if you’ve ever wondered what a ceti eel from Star Trek II: Wrath of Khan felt like, you could schedule an appointment with an audiologist. If that isn’t something you’re looking to try for yourself, the shaping the molds for the Contours is a much more pleasant experience.

The thermoplastic custom molds are easily shaped to fit the contours of your ears, guaranteeing a perfect fit.

Each pair of the Contours come with a set of two thermoplastic molds in a shape that roughly resembles your inner ear. While the headphones only come in black, you can get the molds in plenty of different colors—like red, orange, green, blue, and more. Decibullz also offers molds that are compatible with other manufacturer's in-ears. If your buds happen to be on the list, you can spend about $15 to just get the custom ear molds.

To begin the molding process with the Contours, first you need soften the molds in a cup of boiling water. Once they’re malleable you simply attach it to the earbuds—along with the silicon tip—and push them into your ears like you would with any other in-ears. Then, using a mirror, push the mold so it fills the bowl and all of the nooks and crannies in your ear. Thankfully, it’s a forgiving process and Decibullz provides plenty of instructions to make sure you get it right.

The first thing you’ll want to do is test them out and make sure it’s a good fit—it should sound almost like you’re underwater. If it doesn’t, you can use a hair dryer to soften them again for easy adjustments or soak them again to start fresh. Don't worry if you don't get it right away, even after a few tries my left mold was still uncomfortable and I could only stand to wear it for short bursts of time. But now that I've found the right mold it feels like they’re not even there; the pressure is evenly distributed and I can easily wear them all day at work without a hint of discomfort.

The Sound

It’s not perfect, but it’s also surprisingly great for the price

Although isolation is the unsung hero of great sounding audio, it can only do so much if your buds produce less than stellar sound to begin with. The bottom line is that the Contours are good, but not great. However, they're definitely worth the money despite their few faults.

Starting with the most important factor—the sound—the Contours did very well. There’s a big emphasis on bass and sub-bass sounds, so sounds like electric/acoustic bass and baritone vocals are going to be the first thing you notice. However, they aren’t emphasized so much as to be overpowering.

The carrying case is useful to shuttle around the buds when they have the awkwardly shaped custom molds attached.

In fact, the Contour's emphasis on bass and some higher notes results in something that looks awfully close to an equal-loudness contour. That means that certain notes will be emphasized to complement the way human ears hear frequencies, so everything from classic rock to electronica will sound great. But, there is a slight emphasis on the right channel so some of your music might sound a little lopsided.

You can also rest easy knowing that there won’t be any unwanted sounds in your music. Distortion is something that almost all headphones have and can easily be picked up on by audiophiles or listeners with sensitive hearing. This isn't the case with the Contours. Instead, they measured distortion of a fraction of a percent across the audible spectrum. If you hear any kind of fuzzy, crackling sounds in your music, it’s more likely that it was put there on purpose.

Of course, the true standout of the Contours is its isolation, or ability to block ambient noise. The custom ear molds and double-flange silicone tips should provide plenty of buffer to stop most sounds from the outside world leaking in and disrupting your tunes. Even the most difficult range of sounds to block—sub-bass and bass—are dropped to about half their original volume.

The Bottom Line

It's hard to pass on a bargain like this.

From earbud to audio jack, the Decibullz Contour Custom Molded Earphones are an incredible bargain that deliver impressive audio for their low price. Factor in the enormous savings of custom ear molds and you’ve got some pretty stellar buds that are absolutely worth the investment—as long as you’re okay with its few faults. On the bright side, if you’re only interested in the molds, Decibullz offers adapters for $15 that work with popular buds like the Sol Republic JAX and the Urbeats by Dr Dre, so you don’t have to buy all new in-ears if you only want the custom molds

A custom mold means you'll always have a perfect fit that's comfortable and user-tailored.

If you’re not sold on the up-and-comer Decibullz and don’t want to deal with fitting your own custom molds for good passive isolation, we’d recommend taking a look at the AKG K 323XS's (MSRP: $59.95). They were featured prominently during our 2014 Best of Year Awards in multiple categories, including Best Value In-Ear Headphones and Best Passive Noise Cancellation. Pound-for-pound, they’re incredibly similar to the Decibullz—both in sound output as well as isolation and distortion—and you won’t have to worry about the custom molding.

If you're looking for something with active noise cancellation or you simply find in-ears uncomfortable, then try a good pair of over ears. But, there are still some in-ear varieties worth your time, so long as you’re willing to make a few sacrifices. The Bose QC20i (MSRP: $299.95) have incredible noise cancellation, but you’re going to pay a hefty price for that kind of performance, and the bulky battery pack certainly doesn’t do the QC20i in-ears any favors, either.

Decibullz has created a budget-friendly, relatively hassle-free version of a product that has long been anything but. Tweet It

For what they’re offering, the Contours are, put simply, a great choice. It’s rare to see the headphone industry truly innovate or introduce a revolutionary product—generally speaking, manufacturers pretty much have it all figured out. Decibullz has broken that mold by creating a budget-friendly and relatively hassle-free version of a product that was anything but. It might be a newcomer to the headphone game, but Decibullz certainly looks like it’s here to stay.
