From the Manufacturer

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.

The pure sound quality on these is better than the Bose.

These SE420s have a much wider sound stage, with great bass and midtones.

Update: After a little less than 2 years of regular use, the wiring inside the cable next to the jack broke. I lost good stereo and starting getting crackles. I soon couldn't hear anything.

Luckily, they were still within the 2 year warranty. I sent them in and Shure sent me a pair of Shure SE425-V Dual High-Definition MicroDriver Earphone with Detachable Cable (Metallic Silver).

These new headphones sound identical to the Shure SE 420s but are designed better. The jack insertion now has a 90 degree flexible bend that will hopefully extend the wiring's lifetime. The earphones themselves are detachable in case the cord needs to be replaced later.

Most importantly, for me, the fit is better. I have curvy, small ear canals that must be a bit anatomically strange because they constantly get plugged with wax. However, the SE425's earphones are shaped such that they reach to the back of my pinna and fit within a groove that keeps them snug. Note, though, that I have to use the large, foam sleeves to achieve this effect and that my ears are not particularly large (I am 5'8").

I am happy with my service from Shure and happy with the SE425s. I am just a bit lucky that I was still within warranty.

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).

Color Name: Black
As I indicated in a prior review, I purchased some E3's to upgrade from my E2 when I bought a new ipod. I loved the E2's and as expected the E3 were even better--with more definition at all frequencies and sound levels.

Earbuds (or plugs) definitely have some sweet fit spots to get optimal bass and avoid some tinniness that you can hear when they are not inserted or sitting correctly in your ear. Shure provides a number of ear plug options to help everyone find something they like.

Now, I have compared the E3, the SE420, and my Bose Quiet Comfort headphones sitting in the rear of a jet while traveling (next to the engine). The less expensive E3 beat out the Bose headphones with better high and middle end definition and equivalent outside sound isolation. The Bose headphones have a bit better low end.. but nothing is bone shaking with earphones or headphones anyway. I almost think that the Bose headphones seem muddy in the mid and upper end after listening to the E3 and SE420. The SE420, in my opinion has a richer sounding mid end then the E3, while handily beating the Bose headphones. I think that the bass and most of the high end frequencies are about the same in the E3 and SE420--maybe pushing your budget to purchase the E3 or equivalent... since the E3 cost $179 or so, and the SE420 cost $350.

As for Shure customer service--I had a suspected loose wire in one of the E3 earphones (used for 8 months) leading to dropouts when I would move my head. I got a return form off the Shure website--filled it out and sent it along with a copy of my receipt to Shure. Within 10 days, they had sent out a completely new pair at no charge. THAT is great service. In the meantime I purchased the SE420's while I was waiting for my E3 "repair".

The Shure SE420 may be a dual driver design but it does not sound as so. I purchased these earphones to upgrade from my older pair of Shure E3c's and I was expecting to hear a quality difference between a wideband driver vs a dual driver design. I was shocked after spending time with these that suffice it to say they don't sound any different from my older pair. I had the chance to try out a pair of SE210's as well and I think the SE210's sounded the same as well. Sound is hard to really put into words though so everyone is subjective to there own opinion and experience. However I would like to add that I did my listening experience with these earphones during the day for a few hours and during the night for 6 hours. Day vs Nightime listening is the tests I put these through and for me I am able to hear clearer when I am relaxed so nightime was when I was hopeful to hear a difference but overall I did not hear anything new I could during the day. The bass and midrange don't seem to have any noticeable difference with the added driver vs a single driver design. I tried listening through several sources and it did not make a difference but overall I used a CD player as that was the highest quality source I had.

Comfort wise though the SE series from Shure is much more comfortable to place in your ear and comes with a greater variety of eartips. You don't have to squish the foam tips to place them in your ears. Rather you can just insert them with a bit of a twist. The cables are nice and sturdy and would take some effort to really break so they can stand up to abuse.

Perhaps you might buy these earphones even so and I still recommend you give them a try if you want. You never know how they will sound until you hear them but as for my experience these dual driver earphones don't sound as though they are dual drivers to my ears!
