From the Manufacturer What 80 Years of Audio Experience Sounds Like Today
If you’re as passionate about audio as the musicians who use our microphones, you deserve the legendary performance of Shure earphones. As a leader in the professional audio industry for over 80 years, we’re proud to bring you personal listening products that reflect our experience and ongoing pursuit of audio perfection--and the new SE line of sound-isolating earphones is the latest step in approaching that perfection.
Isolation, not Cancellation
Shure Sound Isolating Earphones are unlike headphones that feature noise canceling technology. For listeners seeking maximum audio fidelity, the differences are key. Noise cancellation technology uses active circuitry to counteract background noise, which may introduce artifacts into your audio. Sound isolating earphones comfortably fill the ear canal and naturally block most background noise for a clear, detailed listening experience--all without the need to listen at high volumes which may risk damaging your hearing.
Legendary Performance At Any Level
Each model has its own unique sound characteristic, providing increased range and detail as you move up the line: SE210 (white) / SE210-k (black): High-quality on-the-go audio utilizing Hi-Definition MicroSpeakers to deliver full range audio, the ergonomic design of the SE210 is ideal for premium on-the-go listening. The SE210 also offers a flexible design for multiple wearing positions. SE310 (white) / SE310-k (black): Breathtaking sound and style featuring Hi-Definition MicroSpeakers with a Tuned BassPort, the SE310 delivers extended range audio and optimized low-end performance. The SE310 also offers a flexible design for multiple wearing positions. SE420 (white) / SE420-k (black): Heart-pounding performance featuring Dual TruAcoustic MicroSpeakers, the SE420 uses a dedicated tweeter and woofer to provide a detailed sound stage. Lows, mids, and highs are distinct and defined for accurate reproduction of all the details of your music. SE530/SE530PTH: Pure audio precision--the SE530 uses Triple TruAcoustic MicroSpeakers to create an expansive sound stage. A dedicated tweeter ensures that highs and mids are incredibly accurate and detailed, while dedicated dual woofers provide balanced, full-bodied bass. The Push-To-Hear Control (included with the SE530PTH) adjusts levels of external sound for maximum intelligibility.
This review is from: Shure SE420-K Sound Isolating Earphones (Black)
Preface: I am a medical scientist and performed a scientific comparison (as best I could) of the SE310, SE420, and SE530 Shure earphones. I used an iPod Touch 3G, playing mp3s encoded at 256 mbps. I listened to various types of music, including classical (Mendelssohn), pop (Lady Gaga), rock (Rodrigo y Gabriela), and "alternative" (Regina Spektor).
Analysis:
Comfort - This is an under-appreciated quality of earphones because - no matter how good a pair sounds - comfort will always get you in the end. The SE530s and SE420s are more comfortable than the SE320s. I'm not sure why this is, but it is probably a combination of factors. One, the actual plastic tubes that the sound comes out of are larger in the SE420s and 530s, making them less "pokey" when placing them in your ears. Two, though the SE310s are smaller and lighter, the do not nestle into the ear as well and thus the fit is less secure.
Style - Try to get the black earphones of any of these models as they are less bright than the white models. Because the SE310s don't fit as well, they stick out from the ears and look a little silly. The SE530s and 420s are more natural shapes, and fit in the ear a little more nicely (though they are large and still quite visible). The 530s have a plastic bronze exterior that may or may not please you.
Sound - You may think that this is the most important category, and it probably technically is. But I have a Southpark-esque truth to tell: The difference in sound between the SE310s and the trice-as-expensive SE530s is minimal. Yes, the SE530s have THREE "microspeakers" with two dedicated "woofers". However, these woofers are not meant to increase bass. They are only meant to give a more accurate representation of bass (i.e. each speaker tiny speaker does not have to handle the entirety of the bass output). This means less distortion on the low end. However, I was not able to detect a difference between the SE420s and 530s in terms of bass distortion or richness.
Soundstage was the major differentiating factor between the three models. The upper two models had more soundstage (i.e. the sounds of a complexly-produced album (e.g. 11:11 by Rodrigo y Gabriela) sound like they are coming from multiple directions and distances, making the listening experience very interesting and rich). I vigorously compared the SE530s and 420s and could detect differences, but my preference for which was BETTER was inconsistent. That is, sometimes the SE530s sounded better and sometimes the SE420s sounded better.
Hiss on mp3 players and my computer was a problem with the SE530s. I tested them using my Acer laptop, my Sansa Fuze mp3 player, and my iPod touch 3G. Each of those output devices created a very audible hiss in the SE530s. This is a major problem if you plan to listen to music as low decibel levels to save your hearing (which is, I think, one of the major advantages of noise-isolating earphones such as these). The audible hiss is due to the unnecessarily high sensitivity of the SE530s. Others have had this problem (see: [..]). The hiss was attenuated in the SE420s and almost gone in the SE310s. The only solution is to use the in-line attenuator supplied with the SE420s and 530s with the volume on the mp3 player turned up and the attenuator turned down. These is no reduction in sound quality with use of the attenuator.
Noise Isolation - Isolation was similarly excellent in all three models. This is perhaps my favorite feature of the Shure line and what makes them my earphone of choice. The SE530s come with a push-to-hear in-line microphone. This seems to be a useful feature when you find you can't hear your friends' words when you are playing music with these earphones in. However, the push-to-hear mechanism is bulky and irritating to use. You will most likely rarely use it if you get it. Also, in order to hear the external world, simp...
