Klipsch X11i Headphones Review
A bite that's much bigger than the bark.
High-end, premium audio was once almost exclusively delegated to the world of big, over-ear cans with 10-foot cables. Fortunately for on-the-go audiophiles everywhere, that's no longer the case. These days, the technology exists to cram big speaker sound into the tiniest little drivers, and Klipsch—a company that's designed speakers for over 50 years—aims to prove it.
Meet the Klipsch X11i (MSRP $349), a set of absolutely tiny headphones that nevertheless boast big, full-bodied sound. An elegant, straightforward design bears out some of the slimmest, most lightweight in-ear speakers we've ever seen. They're extremely expensive, but you're paying for good materials, sleek presentation, and an audiophile experience that fits in a matchbox.
Other than a few spots of under-emphasis in the upper midrange/treble, the Klipsch X11i are great performers—but they aren't audiophile-grade. Points of emphasis in the upper bass range, and under-emphasis in the upper midrange, present a good, consumer-friendly sound that nevertheless means you won't get the flat, even response that's desirable for mixing.
The X11i's boast great accessories and a solid design, but if you're just looking for the best sound quality possible, you could save a bunch of money by going with a less posh pair of in-ears like the JBL Synchros S200i, which are about $99 online.
Design & Functionality
Pretty durable for some of the smallest, lightest headphones ever.
When it comes to in-ear headphones, portability and discreet fashion often cross paths. Whether you're listening to stock earbuds or premium in-ears, the ability to stow them in a pocket or purse is one of the biggest advantages compared to other headphone types. In that same vein, the design of pricier in-ears tend to either subtly focus on fashion or stay out of the way—they don't dominate your head like bulkier over-ear types.
That's the story of the Klipsch X11i in-ears. A tangle-resistant black cable with a three-button in-line mic/remote yields two extremely small, lightweight buds. Materials are durable as can be without introducing excess filigree or extraneous weight. The X11i's boast an elegant focus on minimalism and high-quality materials.
The included accessories reflect the same ethos. Alongside the in-ears themselves, you get a compact, leather carrying case with a magnetic flap, an airplane adapter, a 3.5mm adapter, five silicon sleeves, and an optional shirt clip. The accessories are simple and made to last—and, thankfully, the alternate sleeves are varied enough that most listeners should be able to find a perfect fit.
The X11i's in-line controller is designed to work specifically with Apple devices like an iPod, iPhone, or iPad. I tried them out with a Windows phone and an Android tablet, too. Some functionality, like play/pause, worked occasionally on the Android tablet, but the X11i's mic/remote combo wouldn't function at all with the Windows phone.
Unfortunately, Klipsch doesn't provide an alternate model to the X11i, so if you want to seamlessly play/pause music, control a playlist, or take/hang up calls with these headphones, you'll need an Apple device.
These in-ears aren't without flaw, but most listeners will be quite impressed.
At a listing of $349 per pair, the X11i in-ears are well within the high-end price range. Some of what you're paying for is the super-compact design and durable materials, but naturally buyers should expect very solid performance, too. Testing has revealed that the X11i aren't perfect, but they're still very good for the money.
First and foremost, the sound itself. If you're a fan of cranked-up booming bass, these aren't the 'buds for you. The X11i's take a gradual approach to bass, starting out with very minimal sub-bass frequencies (the lowest of low notes) and slowly adding emphasis until they peak in the midrange.
Many consumer headphones take a semi-aggressive approach to bass emphasis, boosting the low-end so that instruments like timpani, electric/acoustic bass, or baritone vocals leap to the forefront of music. The X11i instead emphasize the midrange more heavily, so instruments like guitars, trumpet, and french horn tend to stand out in the mix.
While this gradual increase/decrease in emphasis leading up to and away from upper bass/lower midrange tones gives plenty of emphasis to most of the instruments you listen to, the X11i provide less of a presence for upper midrange and treble sounds. By comparison, meatier bass/midrange instruments tend to overpower subtler elements like overtones and cymbals. While it doesn't make for a bad sound, it does mean you won't technically get the even emphasis prized by many audiophiles.
Otherwise, the X11i in-ears are solid performers. These lightweight buds are primarily distortion free—there's a bit here and there in the sub-bass range, but nothing that's audible—and, thanks to their ear canal plugging design, they block lots of outside ambient noise while keeping your music private. Other than small areas of under-emphasis in the upper midrange/treble, these tiny Klipsch buds sound great.

Solid performance bolstered by an elegant, durable design.
At $350, the Klispch X11i in-ears are by no means cheap. You're paying top dollar, but you're also getting a lot of quality for that investment.
These in-ears are simple and minimalist, but for some of the smallest and lightest 'buds we've ever tested, they're surprisingly durable; everything from the accessories to the in-line remote are steeped in craftsmanship.
The sound quality could be a bit better, but most consumers will be completely pleased by this cross-roads of design and delivery.
A gentle boost to bass/midrange frequencies gives a good, full sound, though a few underemphasized upper midrange and treble elements may bother golden-eared listeners—especially if they're already versed in high-end sound.
The only sticking point here is the price: For hundreds less, you could secure in-ear headphones like the JBL S200i, which boast similarly good sound and performance for $99.
