From the Manufacturer

From the Manufacturer The Etymotic Research ER-6 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-6 will shatter the headphone myth that bigger is better.

The ER-6 features a noise isolation of 34-36 dB that far surpasses that of active noise-canceling earphones. This makes the ER-6 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-6 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-6 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-6 is so compact and weighs less than an ounce.

Etymotic Research delivers outstanding comfort with the ER-6. The flanged eartips fit snuggly 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-6 is designed to deliver excellent sound reproduction and big, rich bass tones. A good seal in your ear canal will ensure that you here every detail of your favorite tunes. The ER-6 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-6 clean and working properly.

Test results prove the sound accuracy of the ER-6

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-6 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.

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.

What's in the Box
ER-6 earphones, cord with stereo plug, one pair two-flange eartips, one pair foam eartips, two replacement filters, filter changing tool, shirt clip, and pouch.

Customer Reviews

They lack any fullness of bass.
Sound great, and really block external noises.
The foam ear buds are very comfortable.

I've been using these for about 3 years - since I start using an IPod. I listen to huge range of music, all classical styles - from renaissance to atonal, all rock styles, jazz, funk and R&B, rap, brit pop, punk etc. I rarely walk out of the door with my fully loaded 40gig IPod, and these are what goes with them.

Sound Quality is superb, much better than Sony funtopias, and Bose noise cancelling (and don't get me started on the virtually useless Apple headphones). I haven't tried the Shures, so no comment on them. Not as good as my Sennheiser HD 600, but that's to be expected.

They are extremely clear, and revealing, and have great frequency balance across the range. Some complain that the bass is not good enough, and it could be better, but at least it's accurate, this may not matter to some, but flabby artificial bass just annoys me and just becomes fatiguing. The quality is so good its easy to get use to them, but when I temporarily started using the Sony's (having stepped on and broken the ER6s) and then came back to these I realised how good they are. No going back again for me!

Noise isolation is amazing, when I'm on the subway without them I get to (sadly) remember how noisy the subway is, I just don't notice it with these headphones on. I use them when I'm flying, and I did a back-to-back with the Bose and the ER6s blew them away, in both quality and noise isolation. I even get to sleep. Using this style of 'phones when flying or travelling on subways is a must.

Points to note: You do have to put these into the ear canal to use them effectively, and this takes some getting use to. There is some microphony from the cable which may be intrusive especially during very quiet music. Filters may need changing fairly often.

I bought these phones approximately 18 months ago when they cost 20% more than do today, and I never regretted the purchase. My upgrade path took me from the standard Sennheiser earbuds that were (at the time) bundled with various MP3 players including ones manufactured by MPIO, Rio, and Apple; then to a set of Sony in-ear headphones; then these Etymotics. I like the cheaper Sony's price and sound isolation, but not the asymmetric headphone cable or the boomy bass. The Etymotics brought even better sound isolation, smoother sound (with ample, if not accentuated bass) and better detail. For my buck, these headphones inhabit the sweet spot where improved sound quality/isolation begin to encounter the law of diminishing returns. I.e., the ER6 are a lot more of an improvement over the Sony in-ear phones, or stock earbuds, than the Etymotic ER4 or Shure E4c/5c are over the ER6's.

Sound isolation with the ER6 is extremly good -- I use mine daily on Chicago's mass transit system (buses and subways) and routinely for airplane flights. Notwithstanding the soundproof fit, they are comfortable to wear. I haven't experienced sore or uncomfortable ears using the Etymotics, even on long transatlantic flights.

These are not the best choice for working out because the cables rub against your clothes and transmit vibrations as sound right into your ear. In practice, when walking or commuting you can easily drape the cables in a way where this doesn't occur. But running around, leaning up and down, and changing positions frequently, I don't think you could escape the issue entirely. In that case, I'd hypothesize you might want in-ear headphones that drape over the back of the earlobe, which might prevent this from happening.

Over the past three years, I've owned several pairs of Etymotic ER-6s.

I won't try to sway you on their sound quality; some people love them, others don't. I've never had a complaint in that regard. The customer service I've received from the company has been consistently exemplary.

They do have one fatal flaw, and it's the reason I've stopped using them. Unlike the more expensive ER-4s, they're too small to remove from your ear without pulling a bit on the cable.

If you use your ER-6s daily, this cable strain will destroy them within a year or so. In effect, you're not buying a set of earphones, but a subscription that you'll have to renew almost annually with an expensive replacement pair. Unlike Shure, Etymotic charges nearly the full retail price (about $80) for an out-of-warranty replacement.

So, as much as I've enjoyed my ER-6s, I'm afraid I can't recommend them here until Etymotic fixes this design flaw.

After checking with the vendors that these headphones were returnable after being opened, I proceeded to test Etymotic Research's more economically accessible earphones - the ER6 and ER6i headphones - to more objectively make a comparison between the two. I compared their respective power usage, bass response, clarity, connection to the iPod, convenience, and sound isolation capabilities. The overall winner: ER6 Isolation Earphones. The report is below (*note this was not a scientific study but I did try to control whatever I could)

iPod Battery Life Winner: ER6i

The battery life of iPods isn't particularly great, and can be affected by a number of sources such as if EQ settings are on, if the iPod is on "hold", the song-encoded bit rate, whether or not the screen light is on, or in this case, what type of headphone is being used. I tested the battery life of the iPod using the ER6i and ER6 earphones by playing the "All Songs" function which plays every song in the library continuously until the power runs out. By starting it from the first song in the library using both earphones, I was able to factor out the bit rate in determining which earphone lasted longer. Of course, the earphones that lasted longer would be subjected to songs with bit rates that might have been much larger (say 824kbs using the Apple Lossless Encoder instead of the default 128kbs ACC encoder) or much smaller than the earphones that ran out quicker. Therefore, if the longer-lasting earphones hit a string of large bit-rate songs, the battery would run out faster than if there were lower encoded bit-rate songs. Therefore, the times that I will report should not be compared as absolute ratios.
