Product Description

Amazon.com Product Description

These super-light, ear-bud headphones weigh a mere five grams (.18 ounces.) They are the perfect headphone for those who relish lightweight, quality headphones. The silent cap confines the music to the listener's ear and away from those in the immediate area, a plus for those using the headphones in the coffee shop or library. The earphones are also open-air, meaning they allow ambient noises to enter the ear; this translates to a safer headphones, as the listener will be aware of horns, whistles and shouts. These headphones are constructed of an anti-bacterial material for a cleaner listening experience.

The MDR-ED21LP's deliver a quality sound, even with their small size. The groove design and Bass Booster earpiece shape allows for a better fit; additionally, this system creates more bass response than conventional earpiece designs. The headphones use sixteen millimeter drive units for a deep bass and clear treble. Sony also uses neodymium magnets which provide more energy per ounce than other conventional magnets. The PET diaphragm gives the headphones a high rigidity for minimum distortion. Finally, Sony's Acoustic Twin Turbo circuit achieves high sonic output by utilizying sound chamber and duct technology. The cord is one meter long (3.3 feet) for ample range of movement. The housing is a modern, hi-tech, black and silver metallic finish. The compact carrying pouch stores the ear-buds and cord when not needed; its small size fits nicely in a purse or back pocket.

4.0 out of 5 stars Almost Perfect, October 24, 2004

By	G. Parcellano "ginjin3" (Chicago, IL United States) - See all my reviews (REAL NAME)

I got these headphones and also the MDR-EX51LP, I liked these better than the MDR-EX51LP because the sounds it produced was crisper and overall just much better. My only problem with these is that the chord is a little short, just a little over 3ft.

I didn't choose the MDR-EX51LP because that the bass was way too loud. I know that people like bass, but whenever you listen to songs with lyrics all you can hear is the bass, and the spoken stuff gets drowned a bit.

I like the MDR-ED21LP because it was just right, and it was actually louder. I use them on my IAudio CW200 and I usually set my volume to 25. When I have it in that volume level MDR-EX51LP is just too low to even hear it. Even though it goes into your ear canal it doesn't perform as loud as the the MDR-ED21LP. You can also hear some ruffling noise whenever the chord rubs in your clothes, like the stetoscope effect, as another user reviewed.

For the MDR-ED21LP, everything is great, crisp, loud sound, great bass. My only complaint is the chord length.

5.0 out of 5 stars Best sub-$100 earphones, and cheap!, September 9, 2005

By	oldtaku (San Diego, CA United States) - See all my reviews

I've tried all sorts of earphones, and these are the best for under $100 (best I've tried that costs more are the Etymotics). They're cheap, the bass response is wonderful thanks to the extra over the bud 'horn'. You will get much better sound than you will with the flat buds (even the $50 ones) without actually sticking something right in your ear canal.

I use my trusty pair of these with my iPod Nano. For only $10-15 they sound so much better than the headphones that came with the Nano that I feel kind of cheated.

I still think a good pair of headphones (Sony MDR-CD790) are more comfortable for long periods of time, but they're not nearly as portable. Also, the cord on these is sometimes a bit too short (but most of the time it's nice not to have the extra stuff laying around).

5.0 out of 5 stars Excellent Earbuds, December 28, 2005

By	Rui Zamith (Porto, Portugal) - See all my reviews

First of all, there's one very important thing to be said: I'm using an iPod Mini. I'm really amazed with the sound that this small electronic device can supply.. The sound is so great that I even believed at first that the Apple headphones were great. Of course, after some time I started to notice the lack of sound quality, isolation and bass.

After searching the web for earbuds, I've noticed that there are 2 very different types:
- flat earbuds (just like the Apple's)
- canal phones (very expensive Koss, Etymotic or Shure phones, that you really "stick" in your ear)

Of course there are great quality flat phones, but the bass power is always very week, even on the top ones, as I could see with the Bang & Olufsen Earbuds.
On the other hand, the Canal Phones require some time for you to get used to it. The isolation and bass power are really incredible, but they are very agressive to your ears.

Well, the Sony MDR-ED21LP are the ONLY earbuds that I found, that are really in the middle of these 2 types..
They are not flat at all, which really enhances the bass, but they are really NOT agressive to your ears.
Besides, the sound quality is fantastic (remember that I'm using the Powerful iPod Mini), and you can use them for many hours in a row without even feeling them.

And priced like this, I totally recommend these earbuds.
