From the Manufacturer
The Etymotic Research ER-6i Isolator is a compact, earbud-style set of earphones that are ideal for travel and personal listening. If you've ever been a skeptic of earbud sound quality, the ER-6i will shatter the headphone myth that bigger is better.

The ER-6i features a noise isolation of 34-36 dB that far surpasses that of active noise-canceling earphones. This makes the ER-6i a perfect choice for travelers, because these earphones will actively cancel the white noise caused by traffic, trains, or airplanes. These tiny earbuds are perfect for CD, DVD, and MP3 players, as well as laptop computers. Plus, the ER-6i is designed to plug directly into most airline audio systems, so you'll never have to pay for those cheap, airline headphones again.

ER-6 series earphones come with everything you need for a perfect audio experience

The quality of these earphones is outstanding. They deliver such rich sound quality that even the most finicky audiophile will be impressed. The ER-6i earphones have a flat, real-ear response for reproducing CD and MP3 recordings. The sound accuracy is comparable to professional earphones, and provides surprising performance considering that the ER-6i is so compact and weighs less than an ounce.

Etymotic Research delivers outstanding comfort with the ER-6i. The flanged eartips fit snugly into most ear canals, but Etymotic goes one step further by providing disposable foam eartips. The foam eartips provide extra comfort and may offer a better seal in the ear canal. The ER-6i is designed to deliver excellent sound reproduction and big, rich bass tones. A good seal in your ear canal will ensure that you hear every detail of your favorite tunes. The ER-6i flanged eartips are easy to remove and should be cleaned regularly for the best listening experience. Etymotic Research provides you with the tools you need to keep your ER-6i clean and working properly.

The ER-6i earphones have 8 dB higher sound output and increased bass compared to the ER-6 for a slightly "beefier" response

Etymotic Design Means 100% Sonic Accuracy

A perfect recording of a live performance played through earphones with 100% accuracy would produce the same sound at the eardrum as a live performance. A complicating factor is that the acoustic resonance and "horn effects" of the ear can distort a flat signal entering the open ear from a headphone. A perfect earphone will create that same frequency characteristic (called the "target curve") at the eardrum.

Target curves on Etymotic Research graphs indicate 100% accuracy. Commercial recordings often have a high-frequency boost that compensates for the high frequency roll-off in studio monitor loudspeakers and high-quality stereo loudspeakers and earphones. The ER-6i earphones compensate for the high frequency boost added to high-quality recordings. This modification (approximately 5 dB at 10 kHz) is necessary to avoid earphones sounding too bright on commercial recordings. In addition, the ER-6i adds 8dB sound output and increased bass for a slightly "beefier" response for those who like strong bass but still want 100% accuracy on the high end.

Other in-the-ear earphone manufacturers do not report accuracy scores, but Etymotic Research has tested all competitive products. The accuracy scores of Etymotic Research earphones are higher than those of most loudspeakers, and well above all competitive earphones, except electrostatic headphones that cost thousands of dollars.

Customer Reviews

Great for the Gym
After trying many portable headphones for the last ten years, I've finally settled two: the Sennheiser PX100 (with the Koss Porta Pro a close runner up) and these Etymotic phones. The Sennheiser's are great for where you need a little sound to infiltrate the headphones, such as bike riding (not something I'd recomend to inexperienced bicyclists). But at the gym, where the machines are noisy, the spin cyclist class plays god-awful music at top volume and people talk (more on that later), these are the best. With the Sennheiser I had to turn the volume up so high that the batteries were quickly drained, not to mention the damage to my already fragile hearing.

A few pointers. I almost returned them after the first listen. But then I remembered that headphones need to be "broken in" by playing them for awhile. I hooked them up to my stereo and played CD's all night. Big difference the next day. Also, try the different ear plugs. The plastic ones were absolutely horrible for my ears. The grey foam pads worked better. On the Etymotic website they have white ones that are smaller than the grey ones. These worked best for me (narrow ear canals I guess). Order extra filters. I had one plug up on me fairly quickly. Finally, don't wear these where you need to speak with people. You can't hear people talk with these in your ears and music playing. You can barely hear people with the music off. Pulling them in and out is a pain (and people probably don't want to see your ear wax).

Oh, almost forgot. The sound. Great. With no outside noise, the sound comes through wonderfully. They may lack a bit on the bass, but compared to regular headphones at the gym, the improvement is astounding.

Addendum: I originally wrote the review above two years ago. Still using the earphones three times a week. The rubbery coating on the outside has come off, but they still work just fine. The foam plugs get smooshed down and covered with earwax after a few weeks. Just takes the plugs off and put them in a covered jar with hot water, shake around for a minute, then take out and dry. The ear wax should be gone and they'll plump up. Don't use too hot of water or the glue that holds the plastic tube to the foam may dissolve over time. Finally, the noise from the cords rubbing against your shirt can be annoying during quieter music and more energetic work out. This can be avoided by wrapping the cords around the back of your ears. Enjoy!

Big sound, very pleased.
These headphones will not dissapoint unless you like your deep bass in classical or similar types of music. They don't really have the ability to reproduce sound under 45Hz all that well, but all in all, it's an excellent set of headphones for listening to an ipod or such at the gym.

I have no problem hearing clear bass from Bob Marley reggae tracks, popular music like Black Eyed Peas, etc that are usually bass-heavy in the 50-80Hz range. Pop and dance music with bass in the 80-120Hz range is more then adequete.

In order to get the bass to sound well, you will have to experiment a bit with the various headphone plugs that come with it. I find the best bass to be from the foam earplugs. The other earplugs in the picture are more comfortable but do not isolate the sound as much, but still do a very good job overall.

The vocals and general clarity of these headphones are fantastic, they are by far the best headphones I've ever owned. I'd like to try the models with the dual and triple drivers (bass/high or bass/mid/high) but they are in the $300+ price range so that's not in my budget.

Overall I'm extremely pleased with these headphones and I'm looking forward to hitting the gym again.... (one less excuse now!) :)

Blocks the noise, lets the music sing through
This is the black version of the popular Etymotic er-6i headphones, previously available only in white. Etymotic Research introduced this color to complement the iPod Nano and other new iPod models which are available in colors other than white. The ER6i's increased sensitivity over the standard ER6 makes them an excellent choice for an iPod or any other portable MP3 or portable media player.

The er-6i is Etymotic's entry-level noise-isolating earphone. Unlike "noise-cancelling" headphones, which use electronic circuitry to cancel noise (and which can interfere with music and movie playback sound quality), "noise-isolating" earphones like the ER-6i work like earplugs. They are inserted all the way into the ear, forming a tight seal which blocks out external noise but lets pure sound come through the integrated ear-speakers.

Because they reduce external noise levels, they make an excellent choice for frequent fliers. No longer must you crank up the volume to drown out the aircraft engine noise. Now you can simply insert the etymotics into your ears and listen to your music or movies at a comfortable level. They're also much smaller than bulky around-the-ear headphones and come with a compact travelling case for greater portability.

All-in-all, an excellent value and a good choice for those who don't want to sacrifice quality for the sake of portability. For more details, check out the complete review on BigPictureBigSound.com.
