Product Description

Product Description

The MDR-EX71SL is Sony's first closed type Fontopia Design Bud Style Headphones with a resonant bass response. Additional features include a super-light in-the-ear design, new, super-small 9 mm drivers which are ultra-compact drivers that produce powerful sound with space left over for the sonic isolation of the newly-designed soft silicon earbuds.


Sony's MDR-EX71SL earbud headphones make a great pair of phones for your mobile devices, and are perfect for the gym, commuting, or other applications where a little isolation from outdoor noise would do you good.

A great pair of phones for your mobile devices.
Earbud holder and case are supplied.
In-Ear Design

These earbuds fit snugly yet comfortably inside the ear, eliminating the headband so you can enjoy music while exercising, dancing, skating, or whatever activities you love doing.

Soft, silicone earbuds reduce outside noise, help generate powerful bass response, and provide long-lasting comfort for hours of listening. As an added bonus, the earbuds are washable, removable, and replaceable.

Three sizes of earbuds are included to accomodate different ear types.

Super-Small 9 mm Drivers

These new drivers enable powerful sound with space left over for the earbuds, for added sonic isolation.

Long-Throw PET Diaphragm

This helps these earbuds deliver deep, extended bass, down to an incredible 6 Hz; and features low mass for extended high frequency response all the way out to 23,000 Hz.

Neodymium Magnet

Neodymium provides maximum energy in minimum size. Ounce for ounce, Neodymium is more powerful than other magnet materials. Even with the MDR-EX71SLs' small, 9 mm drivers, Neodymium achieves 100 dB of sound pressure output from a modest 1 mW input power.

Precious Metals

A gold-plated mini-plug offers exceptional corrosion resistance, superb conductivity, and low noise; ditto on the oxygen-free copper cord.

Compact Case

This high-impact purple case neatly stores the ear-buds and headphone cord when not in use, ideal for carrying in a pocket or backpack.

Customer Reviews

The sound on these is the best I've ever heard from in-ear headphones, period.
N. Gray
Downside- cord that connects left/right earpieces too short on one side, too long on the other.
J. A Harring
For starters, the cord is too short without the extension and way too long with the extension.

Kudos to Sony.These earphones offer the best combination of isolation, sound quality, comfort, and easy on-and-off design. I am a commuter in NYC, and twice a day I walk a few blocks, take a bus for about 15 minutes and a subway for another 20 minutes. I used to use Koss KSC-35's, but their open-air design had me constantly changing volumes to deal with the various noise levels. I also needed to put the volume on very high to deal with the subway, and I was afraid that I was harming my hearing. I tried the Sennheiser PX-200's and while real comfy, the isolation wasn't enough. Then I tried the Shure E2C's, but the only insert that would fit my small ear canals was the small foam pair. Since you need to take the time to roll these foam inserts up real small before inserting, then hold them in your ears till they expand, that made them very inconvenient for everyday on-and-off use. These Sony's are also a little more comfortable than the Shure E2C's. I have even tried the Koss Plugs, but they do not fit in my small ear canals at all and constantly came out. Thanks to these Sony earphones, I can now travel in comfort and musical bliss for my whole commute without the need to constantly change volumes. As with the Shure earphones, only the smaller inserts fit me on these Sony's. At first, it takes awhile to get used to these, and my ears did get a little sore, but after a few weeks I got used to them. The material that goes into the ear is pretty smooth for easy insertion, and is fairly easy to keep clean. A word of advice: do clean the removable inserts once in awhile in soap and water and keep your ears clean! The sound on these is very good with solid bass. Perhaps not the best you will hear, but better than your average moderately priced headphones of any design and brand.Read more ›

First of all, I did ALOT of research on canal/earbud phones (including reading all of these reviews and many others on other websites) before settling on a pair for purchase. I am pretty much a audiophile however that doesn't mean I expect pefection with every purchase, I realize there's ALWAYS going to something that I wish sounded, worked or was designed better. I am also a bargain shopper not willing to shell out $500 and up for headphones, mainly because I cannot not afford it and I (like the rest of us) don't like being overcharged.
That being said, let me start with that fact that I actually purchased the Sony MDR-EX51LP's not the MDR-EX71SL's. The reason? After my research I discovered there's not much difference between the 2, save the short cord/extension problem you will read about later and the fact that they carried them at Best Buy which made it easier to return them if necessary (I came across comments that stated Amazon charges you if you decide to return the MDR-EX71SL's).
Let me start by saying I am VERY satified with my purchase. I bought them about 3 weeks ago at Best Buy for $39.99 plus tax, roughly the same price Amazon is charging for the MDR-EX71SL's. I was looking for earphones that would block a significant amount of exterior sound, fit snugly in the ear and not fall out as well as produce a quality of sound I would appreciate. I can say all of those needs are met with my MDR-EX51LP's. There are a few things you should know about these earphones though.
#1 If you don't like having to fiddle with little things to get great sound, don't buy these. The multi size silicon earbud coverings take a little time to figure out. You must have a complete seal to hear clear bass so play with the sizes to see which one fits you.

Sound reproduction:
- Because it's an earbud and for this price, you can't expect the sound reproduction of a $100 over-the-head headphones. The bass is quite nice for size of the earbud, the bass may become a bit overcoming for some songs, the highs are there, I just think the mids are a bit weak. Size matters, and for such tiny thing to give an output close to my Sony MDR-V600, it's quite nice.
- I'm amazed how many people do not like the extra length on the right side. I love this design because youcan put the right cord behind your head and you will never have worry about another cord being in your way in front of you. The extension of the cord is meant for people who have MP3 players with remotes, therefore shorter length and you won't have a cord dangling around.
- The one I purchased came with 3 sets of different size earbud, and I found the middle ones to fit best. I do not have the problem of others while working as they stay snug in my hear the whole time (treadmill, elliptical machine, etc...)
- For under $40, it's the best earbuds for the price and some very nice sound reproduction. Design is especially convenient if you have a remote and you like the length to pull the cord behind your head.

Please note that the following review was originally intended for the Sony MDR-EX51LP headphones. Many reviews of the EX71SL's make it very clear that the two models share the same construction issues, and I feel that it is in potential buyers' best interests to include this review. Nevertheless, please take this review with a grain of salt: I am confident that everything applies to both models, but I do not have firsthand confirmation of this. Without further ado, my review:

You're probably confused about the reviews you've read regarding this product. People either give these earbuds five stars, saying that they're the greatest thing since sliced bread, or one star, complaining about a cord made of jelly. And then there are the people who complain about the lack of bass, but that shouldn't be confusing at all: These people are not inserting the earbuds properly into their ear anal. You can ignore these reviews.

The confusion regarding the first two types of reviews lies in when the reviews were written. It seems (from my own experience, and that of others) that around February 2005, which I will from here on refer to as "Day X," the material of the cord was changed. I have no words to describe the digust I feel towards the new material: After a few weeks, it literally turns to mush and starts peeling off. I don't know what Sony is trying to pull, but it's unfair that so many people keep buying these earbuds after reading the good reviews, which happen to be written either before Day X, or before the disintegration starts. It's also quite annoying that those who bought the earbuds prior to Day X keep telling others to ignore the bad reviews on Amazon, as their earbuds have lasted them years. Of course they have! You bought 'em before Day X, people! Oy.
