• Grado is now shipping their in-ear headphones, the GR8. I'm assuming Grado really wants you to read that model number phonetically, so I'm going to try to help them out. The company is known for their gr8 sounding over-the-ear, open-air headphones like the SR60, so the GR8 is a bit of a departure for the company. As far as specs go, the earphones cover the full 20Hz - 20KHz audible spectrum and are powered by a moving armature driver. Looks gr8 on paper, but with so many other in-ear headphone options available, it's probably best to wait until more reviews start trickling in before you pick these up. At $300, you want to be absolutely certain the GR8 are the omg gr8est b4 u buy k? Now shipping. [Product Page via Engadget]

The key to the S4i's dynamic music performance is a moving coil micro-speaker with controlled damping, a feature that allows it to deliver smooth, full-bodied sound similar to a more expensive design. A dual neodymium magnet motor structure, in each of the 8.5 mm drivers, establishes the S4i's damping characteristics. It's a quality that allows kick drums to "attack" and Intermodulation distortion, or IMD, to be significantly reduced.

If you are a real audiophile that trusts Klipsch products, these may be worth picking up. As you might expect, loyalty will cost you—the S4i will run you $100 this August while Apple's headset can be had right now for $80.

New Breakthrough Product: Klipsch® Image S4i In-Ear Headset
One of the first third party headphones with integrated microphone and remote

INDIANAPOLIS, IN (July 21, 2009) - Klipsch plans to re-define the music listening experience with its new Image S4i, an in-ear headset that combines the company's acclaimed sound performance and amazing comfort value with a unique in-line microphone and remote.

"Designed for iPhone and iPod users, the Image S4i is a breakthrough product that simplifies on-the-go lifestyles-you can take calls while commuting or exercising, as well as control your music library," said Don Inmon, Klipsch director of marketing and product development for personal audio.

The Image S4i works seamlessly with the iPhone 3GS, third generation iPod shuffle, second generation iPod touch, fourth generation iPod nano and the iPod classic 120GB. The headset features Apple's advanced three-button microphone and remote system that easily handles the voice and/or music control of these Apple products.

Furthermore, the S4i remote is among the first to be fully compatible with the Apple VoiceOver feature on the third generation iPod shuffle, which allows you to hear the name of the playlist, song or artist with just the press of a button.

According to Paul Jacobs, president and COO of Klipsch Group, Inc., when you combine Apple's incredible products with our 63 years of experience in high-performance audio, you can expect one of the coolest, most advanced headset designs out there. "It's definitely a platform that will dynamically change the music experience for our customers."

Unlike most headsets, the S4i positions its in-line microphone and remote at the yoke-where the two cables meet at chest level-to create a more natural feel when answering calls and controlling music. Because the microphone is a highly intelligible 360-degree design, you don't have to talk down into it; you can speak as if you're having a face-to-face conversation. Additionally, the microphone features echo cancellation, which keeps it from picking up the external noise around you.

Because durability is a major concern when it comes to headphone and headset cables, Klipsch has gone to great lengths to ensure the S4i cables are a well-balanced combination of being robust as well as discreet. The company has added appropriate strain relief at every cable connection point to help prevent wire damage, while also putting them through extensive "real world" testing.

The Image S4i utilizes the company's exclusive oval ear tips that provide comfortable long-term wear. Unlike circular-shaped designs that put stress on the pressure points inside the ear, Klipsch's oval ear tips naturally fit the contours of the ear canals. These ear tips also offer superior passive noise-cancellation, blocking out almost all ambient noise and providing excellent bass.

"Once you have the right fit and seal, these headsets are virtually impossible to feel," said Mark Blanchard, senior acoustic design engineer for Klipsch and inventor of the company's oval ear tips. "When we began studying three-dimensional ear impressions, it was discovered that nearly everyone has an oval-shaped ear canal. We couldn't believe that no one else had yet considered the anatomical shape of the ear canal when designing in-ear headphones."

Blanchard also mentioned that when you wear Klipsch headphones or headsets, you don't need to turn up the volume as loud because a good seal dramatically reduces background noise-a feature that could definitely help preserve your hearing.

The key to the S4i's dynamic music performance is a moving coil micro-speaker with controlled damping, a feature that allows it to deliver smooth, full-bodied sound similar to a more expensive design. A dual neodymium magnet motor structure, in each of the 8.5 mm drivers, establishes the S4i's damping characteristics. It's a quality that allows kick drums to "attack" and Intermodulation distortion, or IMD, to be significantly reduced.

Available in a piano black finish with chrome accents, the Image S4i comes with a two-year warranty and includes a premium carrying pouch; small, medium and large ear tips; small/medium dual flange ear tips; an ear tip cleaning tool; and a clothing clip. Priced at $99.99 (U.S. MSRP), the S4i will be available for purchase at klipsch.com, Apple, InMotion and Amazon in August.

Yes. The SE115's bass driver is so improved, I actually don't want to go back to my SE110s. The SE115s provide a clean resonance in your ears that was previously missing, but not at the cost of overall clarity. Shure says the magic lies in their second-gen Dynamic Microspeaker, previously found in the larger-bodied E2c model, finally shrunken down to fit in earbuds this small.

To test, I went with two songs: Charles Mingus' "Solo Dancer," because it makes use of a subtle, melodic bass in the background and The Bug's "Poison Dart," because it's one of the more in-your-face, bass-heavy tracks to come out in the last five years.

The SE115s outperformed the SE110s in both instances, able to put that extra rumble in your head without losing the nimbleness and the dexterity of the music. Mingus' beefy double bass, in particular, took on new life with the SE115s stuck in my ears—going from a complementary noise, to an instrument demanding to be heard. For the upper register, there's really not much distinction at all, on those tracks and on others with less basso profundo, such as The Beach Boys' "Caroline No." Whether or not you want more low-end will may come down to personal preference, but this is a natural augmentation. Think of it this way: The fuller sounding SE115 simply does a good job demonstrating what's missing from the SE110.

On the technical side, the SE115 has a slightly better frequency response range. I used 20-20000 Hz and 20-200 Hz WAV files to listen for differences between the two sets. I noticed the SE115s rumbled longer on the low end and even squealed at a little higher pitch than the SE110s, but in that upper register, it's probably nitpicking to draw any significant difference.

Externally, these new SE115s share the exact same body and ear cushion options as the SE110s so the comfort factor is identical. The black pair has gold logos instead of silver, and if you're more daring, they also come in red, blue and pink. They both have the same breakaway cable, so you can add the original cellphone-mic extension if you so choose. The lightweight and foam-covered, in-canal drivers have never been a problem for me, but again, it all comes down to personal preference. In any case, at $100, I can't help but champion the SE115s as the best relatively affordable headphones at the moment. [Shure's Product Page with MSRP—shop around for the $100 price]

First, some ground rules on the scope and purpose of my testing:

The headphones tested are all what you'd consider "upgrades" rather than "replacements" for the crap headphones that came with your MP3 player. While I capped pricing at $200, my "cheapest" pair started at around $40. The three tiers are under $100, $100-$150, and $150-$200.

The most practical measure of sound quality is to just sit and listen. I focused on in-ear headphones because they are built not just to jam a driver right next to your ear, but to block outside noise. It's simple: less ambient noise = better experience.

In the spirit of cutting out the vaguely scientific marketing jargon, my tests were unscientific, but consistent across the board and based on real-world situations. The methodology was simple: a current-gen iPod, a sonically diverse playlist of music and, for isolation testing, a seat on the 14 bus in San Francisco, then some time next to a white noise machine.

With so much of the earphone inside of your ear, rustling of the cable can cause some serious noise. If the cable isn't properly buffered from the earphone, the deep, annoying shuffling can interfere your music when you try to walk or turn your head. That's why I made note of "cable noise"—this isn't to suggest there was some kind of buzz or white noise from the cable itself.

The Losers: This is a tricky price point, as some stock earbuds (Apple, Sony) are actually pretty good. Slapping a rubber cuff on a half-baked product doesn't justify a price of $50+. In the case of Apple's in-ears and the CX300s, you aren't really experiencing a different class of audio than with stock buds, though there is a marked improvement. The CX500s put on a good show for bass junkies, but that's about it. Creative has a nice product with a great price, but it just can't measure up to the metro.fi on the performance front.

$100-$150
The Winner: Shure SE110 This price point offers the highest price to performance ratio, and the SE110 is the best of the lot. If you can get over the deep penetration and the over-ear looping, you'll find that the SE110s are comfortable, block out plenty of ambient noise and most importantly produce stunning, immersive sound. The tones are wisely balanced, and quality is at the level that you'll be noticing new things about songs that you've heard dozens of times. Decent discounts are available at various online retailers, as is the case with most of this category.

The Losers: Manufacturers know that this is a sweet spot for consumers, so the market is crowded with good options. The hardware starts to look a little more "professional," or more accurately, "weird." Etymotics, always fans of producing earphones that are really good on paper, fails with the ER6 not because of quality issues, but because the buds are awkward and overwhelm with the high and middle tones. The company's new earphone tips, however, are amazing (more on this below, in the more expensive category). Ultimate Ears loses their luster at this level. Creative is yet again a nice runner-up; the Zen Aurvanas are very capable, but couldn't supplant the crystal-clear SE110s.

$150-$200
The Winner: Etymotics hf5 Ostensibly designed with portable music players in mind, the hf5s solve the balance problems of the er6 models and much, much more. They're cool looking (with the right tips, they look like sci-fi laser pistols), have little to no cable movement noise and reproduce sound in a way that is both perfectly clear and highly enjoyable. Everything about these gives the impression of quality, from the brushed aluminum finish to the way that music suddenly sounds distinctly layered in a way that it didn't before, and that it doesn't on many similarly priced units. One caveat, though: the hf5s (and the er6s, for that matter) must be used with the new foam rubber tips, called "Mushrooms." They're a little phallic and sort of a sickly gray, but they are leaps and bounds better than Etymotics' trademark flanged tips. The tighter seal that these offer to most people is conducive to better listening, and the isolation properties are superb. You can't hear anything else with these guys in. Every manufacturer should have something like this. According to the Etymotics people, by the time the hf5s ship these will be standard issue. Good.

The Losers: To sum up the category: Expensive without enough added benefit. Spending $100 will get you a phenomenal listening experience, so it's hard to justify spending more. The $200 cap was intended to filter out the luxury market/audiophile products that tend to show up at about that price, but hints of both are apparent here. The Shure SE210s are a wonderful pair of earphones, but the large premium over the SE110s is a dealbreaker, as side-by-side comparisons expose only the slightest variation in sound quality. The Klipsch Custom-2s are more of a luxury item than the others, with woven cable housing and a case that is ready for you iPod as well. Harman Kardon is just batting out of their league here, and Ultimate Ears doesn't improve on their cheaper models, even introducing some pretty terrible cable noise.

If you're looking to get the most out of your MP3 player, you'll have to spend some money. But as it turns out, the general rule is that once you pass about $100, your audio improvements will become smaller and more expensive. After reviewing all of these earphones, one simple fact is very clear: If I were in the market for a new set of earphones, I would buy the SE110s.

We've tried other earphones with similar characteristics, and if you get that seal just right, the result is skull-pounding bass and crystal-clear highs. Koss claims frequency response of 10 to 20,000 Hz with these babies. Yeah, right. We'll believe it when we hear it.
