The Epics have a few specialty features that help elevate the design—like a tangle-resistant cable and so-called "cush fins"—tiny flaps that extend up from the buds to nestle more firmly into the rook of your ear. The Epics also produce a rich, consumer-friendly sound with practically no distortion and enough isolation to keep you focused on your tunes.

Even though they sound great, you're going to have to pay extra if you want the stylish looks of the competition. The Epics are a solid investment for notably balanced sound and a durable construction that won’t go anywhere once you put them in.
Even though they're relatively affordable in-ear headphones, the JLAB Audio Epic Earbuds (MSRP: $49.99) tested on par with much more expensive models. They had a frequency response that closely matched an equal-loudness contour, practically zero distortion, and enough isolation to fall in league with other in-ears. I’ll break down our results for each test below and explain how we arrived at our findings.

Thanks to a few standout features, they're a step above average

Don't let the plastic housing fool you, the Epics have an unusual design that belies their value-level construction. There are also a few bonus features that sweeten the deal and make the Epics far more than they seem to be at first glance.

The Epics use a standard 3.5mm audio jack connected to a flat, tangle-resistant cable that’s about 4.5 feet long. It ends with a casing that’s shaped like a teardop and stylized with JLab’s three-piece logo. While we went with the jet black/granite color option, you can choose from solid jet black, electric blue/graphite, or glitter gold/cloud. The casing is plastic and doesn't seem particularly durable, but JLab did include a little surprise via the attached gel cush fin.

The Epics come with plenty of spare tips and fins of different sizes, so finding the perfect fit should be a cinch.

While in-ears get bonus points for their portability, they have a whole other set of problems that over- and on-ears don’t. We often have a bad habit of shoving our in-ears a little further than they’re meant to go, which can lead to discomfort. But, if we don’t push them in far enough it’s all too easy for them to fall out. JLab killed two birds with one stone by including cush fins.

Cush fins are, as the name implies, small gel inserts that are attached between the casing and the gel tips, and are meant to be turned so they fit snug in one of the crevices of your ear. The added support practically guarantees they won’t fall out and should ensure that you don’t jam them too far into your ear either. Be careful, though—if you turn them too far they can get uncomfortable very quickly.

While the tangle-resistant cable is another big deal that makes these buds excel, JLab also included an in-line remote for added control. It’s a single-button remote that can be used to play/pause your music and skip/rewind tracks. The lack of volume control is unfortunate—especially when you’re on a crowded subway and are forced to fish your phone out of your pocket—but ultimately not bad enough to be a deal breaker.

The so-called "cush fins" fit in the folds of your inner ear for a snug, yet comfortable, fit.

In-ears are notoriously fragile and it won’t take long for most pairs to break from being wrapped around your phone or in a ball and shoved in your pocket. Plenty of manufacturers subtly hint that this is a terrible way to treat their product by including a carrying case to help keep your in-ears safe when you’re not using them. The case here is a sturdy, zippered clamshell and is just big enough to hold the earbuds and a few spare tips and fins.

Save a lot of headaches down the road by finding a good fit first.

A carrying case won’t do you much good if you lose one of the gel tips, though. Thankfully JLab also included plenty of spare tips and cush fins of varying sizes. Along with the basic, medium sized tips that come on the buds, there are three alternate sizes included: a small, another medium, and large. There are also two double-flange tips—which block a touch more ambient sound compared to the standard tips—in a small and medium size. Rounding out the collection are three alternatives to the cush fins—a simple circle, a medium-sized variety with a small fin, and a version with a large fin.

We’d recommend taking the extra time when you first get the Epics to try out the different sizes and styles to find the perfect fit. Not only will the earbuds be more comfortable to wear for longer periods of time, but they’ll also be far more secure so you don’t have to worry about them falling out if you go for a run.
The Epics follow an equal-loudness contour—represented by the blue line below—fairly closely across the audible spectrum. This means that certain frequencies—like bass and treble—are boosted because human ears have a harder time hearing those sounds. If done correctly, an equal-loudness contour does exactly as its name implies and makes the entire spectrum able to be heard equally as well.

When we test frequency response we start with a parent signal of 78dB and chart the output from the headphones from 20Hz–20kHz. For the Epics, the sub-bass and bass frequencies (0-300Hz) get a serious boost to right around 88dB, which means they sound twice as loud as our parent signal.

The frequency response sticks fairly close to an equal-loudness contour, which is great news for almost any genre of music.

As the frequencies reach the midrange (300Hz-2kHz) the output steadily drops from 86dB until it hits 72dB. At 1kHz there’s another small boost—to follow the equal-loudness contour—that bumps it back up to 76dB, which is consistent with our parent signal.

There’s another drop following the end of the midrange frequencies and introduction of the upper mids and then a bigger spike for the high frequencies. In the end, no matter what genre of music you listen to, it should sound nice and balanced with the JLAB Epics.

Surprisingly good for the price

The Epics don't stop at interesting features though. They also produce rich, detailed sound across the audible spectrum. Whether you’re listening to classic rock, soulful jazz, or the bright airy sounds of an orchestra, it’s going to sound great coming from the Epics.

This is in large part thanks to how the Epics reproduce music across the frequency spectrum. In the chart you can see that they closely follow what’s known as an equal-loudness contour (represented by the blue line in the graph). An equal-loudness contour boosts sounds that are naturally more difficult for the human ear to pick up—like sub-bass and some high frequency sounds—so they can be heard equally as well as the other types of sounds.

The frequency response sticks fairly close to an equal-loudness contour, which is great news for almost any genre of music.

No matter how good the sound is it won’t matter if outside sound leaks in and contaminate it. Thankfully, in-ears have a natural advantage when it comes to blocking ambient sound from interrupting your jam session. This is compounded by the double-flange gel tips that are packaged with the Epics because they're able to block even more sound.

If you use public transport to get to work, you know how obnoxious the subway or bus engines can be. A good pair of headphones with plenty of natural isolation can drop the relative volume of those engines until they’re a shadow of their former selves. The Epics don’t quite reach this level. While they do diminish those deep bass sounds, it’ll only be enough to take the edge off. Midrange sounds, like office chatter or the general bustle you hear on the streets, will receive a similar treatment and be lowered by about 25% of the original volume. The relative volume of higher frequency sounds will be dropped far lower, but it’s not very likely that you’ll encounter sounds in those ranges in your typical day.

The cable comes with a one-button in-line remote, which can be used to play/pause music but not to adjust the volume.

A quick note: these results are based solely on the earbuds and don’t factor in the relative isolation that louder music affords. Also, plenty of people think the double-flange tips are uncomfortable, so the benefits of blocking more ambient sound might not be worth the sacrifice in comfort.

There's a reasonable concern that cheaper headphones won't sound as good as more expensive models. If the build-quality is low, it can even be heard as distortion—fuzzy, crackling sounds—that lower the quality of your tunes. You won’t have to worry about that with the Epics though, which had practically imperceptible distortion. Rest assured that you won’t have to sacrifice quality while you save money on these earbuds.
Almost every headphone we’ve encountered handles distortion—fuzzy, crackling sounds introduced by the hardware—in different ways. Some of the cheaper headphones out there will have a hefty dose of it, while other, more expensive models will feature hardly any at all. As far as we’re concerned though, anything at 3% or above is grounds to be considered audible to the average person.

Distortion in the Epic in-ears is practically nonexistent, if you hear any fuzzy, crackling sounds, they were put there on purpose.

Luckily, these bargain earbuds don’t even reach a third of that. Instead, the highest level of distortion we measured was in the sub-bass range, which peaked at .8%. Considering that distortion is notoriously difficult to hear in the sub-bass and bass frequencies anyway, it’s highly unlikely you’ll hear anything that wasn’t meant to be there.

Clear winners

It’s hard to argue with the rich, consumer friendly sound of the Epics especially considering it’s paired with solid construction and specialty features like the cush fins. Even though they don’t get top marks for looks, the low price point makes them an easy buy for anyone that wants more bang for their buck.

But, if you want premium sound with good looks to match it we’d recommend shelling out the extra cash for the JBL Synchros S200i (MSRP: $129.95). They have a handsome, spoke design and rich, balanced sound that also follows an equal-loudness contour. All of which was enough for them to win a 2014 Best of Year Award for Best In-Ear Heapdhones.

The small clamshell case is durable enough to help the Epics last for a long time.

If you want to spend just a little more money and like the idea of earbuds that better fit your ears, the Contours (MSRP: $59.99) from Decibullz might fit the bill. Typical custom molds can cost upwards of $1,000 and are painful to boot. Instead, the Contours feature twin custom molds that can be shaped via a simple, painless process using hot water. Decibullz may be the new kid on the block but they’re poised to cause quite a stir.

Innovation comes at a cost though and the sacrifice in build quality can quickly come back to bite you and likewise not everyone has $130 to spend on a pair of in-ears. Without sacrificing quality—in build or sound—the Epics from JLab offer a surprisingly solid balance that place them a step above the competition.
Thanks to the gel tips that fit into your ear canals, in-ears have a natural advantage when it comes to blocking the ambient sounds of the outside world. The amount of isolation will also increase if you use the double-flange tips that come packaged with the earbuds.

Using the double-flange tips for extra isolation, the Epics perform on pair with other, similar in-ears that we’ve tested. Sub-bass and bass sounds (0–300Hz) get a small decrease in relative volume, but it isn't enough to make a noticeable difference. Meanwhile, the midrange sounds (300Hz–2kHz) hover around 75% their total volume before dropping to be half as loud as normal around 800Hz.

The upper mids (2–6kHz) and high frequency sounds (6–20kHz), however, quickly drop to almost 1/16th as loud around 4kHz before a quick rise back to 1/8th as loud at 5kHz. While this is normally great news, you’re unlikely to encounter ambient sounds in these ranges so it’s practically a moot point.
