An excellent introduction to premium audio via sound isolation, the discrete, comfortable and affordable Shure SCL2 earphones in clear use Shure's award-winning earphone technology for a rich response across the full sonic range. Utilizing Shure's award-winning earphone technology, they're great for use on live stages as well as with any home or portable audio device in noisy environments such as bus stations, airports, and more. The SCL2 earphones feature Single Dynamic Micro Driver technology that delivers full range sound and isolation from outside noise.
Shure's sound-isolating SCL2 earphones in clear. Sound isolating earphones provide sound quality far beyond the technical ability of the most expensive earbuds and isolation that's superior to the best headphones. By creating a secure fit between the sound source and your ear canal, unwanted background noise is blocked out while the music comes straight in. They provide a comfortable fit thanks to the three sizes of three different included sleeves--orange foam, clear and gray flex. Experiment with the size and style that creates the best fit for you--a good seal is key to optimizing sound isolation and bass response as well as maximizing comfort during extended wear. A durable and compact carrying case is included with the SCL2 to provide a convenient, tangle-free solution to store your earphones. Sound Isolating Technology Headphones generally enclose your ear or rest on top of it. Regular earphones (like the earbuds often packaged with CD players) sit on the outside of the ear. Sound isolating earphones are different. They are designed to fit inside your ear canal, where they create an isolated listening area that is responsible for their superior acoustic properties. Sound isolating earphones were originally developed as Personal Monitor Systems to allow musicians to hear their own performances in loud onstage environments. Sound isolating earphones work by using soft, pliable sleeves to block background noise, allowing small, high-performance drivers to deliver incredibly precise sound directly to the ear. Is isolation different from noise cancellation?
The seal created by a sound isolating earphone physically blocks most frequencies of background noise. Active noise cancellation headphones are generally larger, heavier and battery-driven. The active cancellation process negates selected frequencies through a complex process that can even introduce unwanted artifacts into the resulting audio. The natural sound isolation properties of a properly fitted in ear earphone exceeds the performance of even the most expensive active noise cancellation alternatives. How do in ear sound isolating earphones work?
By selecting from an assortment of included soft, flexible sleeves, you're able to personalize the fit of the earphones to your ears. The sleeves conform to the unique shape of your ear, creating a seal that isolates you from ambient noise. Why is isolation important?
Sound isolation makes it possible to hear greater detail at a lower volume than is possible with earbuds or most headphones intended for portable use. Lower-volume listening means less fatigue over extended periods and is safer than trying to overcome background noise by turning up the volume. This makes sound isolating earphones the ideal choice for commuting, travel, exercise, study, or work--any activity where you desire portable, hi-fidelity sound.

This review is from: Shure SCL2 Sound Isolating Earphones - Clear
Shure tried to pack a lot of performance into the SCL2 earbuds, and, in general, they succeeded. In sound isolating (as opposed to noise-cancelling) phones, the design challenge is to create a seal between the wearer's ear canal and the unit such that a minimum of ambient sound "gets by" the seal and interferes with the sound being generated by the miniature set of diaphragms housed within. From a sound-isolating standpoint, it's difficult for the seal to be "too tight." The tradeoff on seal effectiveness is usually wearer comfort.
Shure has done a good job with these SCL2's. They are light, but that's to be expected, even desired. They are a little wierd-looking, protruding from the ears about 1/2 inch, but if you've paid your dues seeking sonic excellence, you've seen plenty of wierd over time. These are not offensive in that regard. Besides, they sound good, so what's the complaint?
When they arrived, I decided to put them to a serious listening test. My iPod has over 7,000 songs and 30 feature movies in a highly eclectic collection, so I have plenty of opportunities for a challenge.
I've always thought that solo piano, well-recorded, was a supreme test for speakers. If they could reproduce the full range of sounds without noticeable response peaks and valleys, they were probably pretty good speakers. The same criteria, I believe, apply to earphones as well.
I used my collection of Angela Hewitt recordings of J. S. Bach's piano works to take the phones to the gym, and to my great pleasure. The response was clean, transparent, and, as far as I can hear, linear. In short, an A on that count.
At this point, it's probably the right time to address another reviewer's complaint about the bass response of the SCL2's. I can understand how someone might declare these phones inadequate. All I can say about it is that I like bass, but I like it the way it was recorded (you can't easily make a case that you expect it to sound like live music, because not all sound engineers attempt to make it sound like it does fifth row center in a sonically pure concert hall; also, it depends on where you sit in that venue as to the kind of sound you might hear.) In my opinion, these phones are not inadequate. They just don't overemphasize bass tones like some phones are designed to do. Excess bass inthese phones might well be painful.
After about four hours of listening to classical piano and a playlist of Tschaikowsky symphonies, I was ready for some rock, pop, and jaaz. The Shures really shined here. They brought out nuances that I've never heard in recordings that I've listened to for 40 years. As Martha Steweart might say, that's a good thing.
Setting up the product is not a chore, but requires a few minutes of your undivided attention. Shure packs three different sizes of three separate designs of sonic seals. There are clear silicone gels, black extra-soft rubber seals, and some orange memory foam ones. I can't say they've covered all bases, but I found one that creates the desired sea...
