Which ER4 microPro is right for you?
ER4B earphones are for the binaural recording enthusiast. Ideal for use with material that has not been equalized for loudspeaker playback.
ER4S earphones are designed to compensate for the high frequency emphasis in recordings. Performing musicians often use them because the response matches that of most monitor loudspeakers. Popular with musicians, recording engineers and audiophiles, ER4S can be used with a headphone amplifier if desired.
ER4P-T Portable Travel
ER4P-T is intended for sound engineers and audiophiles in constant motion and can be used with portable devices without an additional amplifier. Compared to the ER4S, the ER4P-T has 10dB greater output at high frequencies and 13dB greater output at low frequencies.

The ER-4P MicroPro noise-blocking earphones from Etymotic Research offer realistic sound reproduction and noise isolation that far surpasses that of active noise-canceling earphones.
From the Manufacturer
From the Manufacturer The ER-4P MicroPro noise-blocking earphones from Etymotic Research offer realistic sound reproduction and noise isolation that far surpasses that of active noise-canceling earphones. The ER-4P earphones--which require no batteries--can be plugged into any audio source. They can be used with portable CD, MP3, DVD, and other players without an additional amplifier.
The ER-4P earphones were designed to match the response of the ear, creating nearly perfect sound reproduction. They reduce external sound naturally by sealing your ear canals, without the added weight, bulk, or external power supply required for active noise-canceling. Their external noise exclusion (up to 33 dB using the supplied 3-flange eartips and 41 dB with foam eartips) lets you hear the full dynamic range of recordings without your having to play them at unnaturally high and unsafe levels.
The ER-4P comes with everything needed for audiophiles, performing musicians and recording engineers .
See how the ER-4P measures up in response accuracy.
ER-4P earphones can be used with portable CD, MP3, DVD and other players without requiring an additional amplifier. As compared to the ER-4S, the ER-4P has 10 dB greater output at high frequencies and 13 dB greater output at low frequencies. The higher sensitivity and enhanced bass of the ER-4P have made it the most popular earphone for most uses.
Noise reduction with ER-4 MicroPro earphones occurs naturally from the inserts. Other earphones with active noise-cancelling add circuit noise and require bulky batteries.
In-the-ear, high fidelity transducers combine flat frequency response with isolation from external noise.
The white 3-flange eartips provide 35 dB average external noise isolation. Foam eartips provide 41 dB average external noise isolation. Lowering surrounding noise allows the listener to hear the full dynamic range of recordings at lower reproduction levels.
ER-4 MicroPro earphones are ideal for a variety of consumer uses such as personal CD and DVD players, MP3 players, and computers. Professional uses include mixing and stage monitoring in the studio and during live performance.
What's in the Box
ER-4P MicroPro earphones, a 5-foot cord with 3.5 mm stereo phone plug, a .25-inch stereo phone adapter plug, six 3-flange eartips, 10 foam eartips, a filter-changing tool, 4 replacement filters, a shirt clip, a zippered pouch, a storage box, a user's manual, and warranty information.

Sound wise, honestly, they are great.
However, trust me when I say that these WILL BREAK and stop working within two years.
I have personally purchased 4 sets of these over the years because the sound quality really is great, and the isolation effect means that you can comfortably use them on the train or at the gym (though they do have a noticeable microphonic effect if you touch the cord, which Etymotic have never fixed, and which is quite annoying).
However, the build quality is CONSISTENTLY POOR.
I have NEVER owned a pair of these that has lasted longer than 2 years without either the cord having problems, or more commonly, one or both of the ears totally giving up the ghost.
The last pair only just made it over the 12 month mark, and a pair my dad had failed in one ear after about 10 months if memory serves.
It used to be that these headphones cost considerably less money, and so because the sound is good, I would end up puckering up and buying a new pair.
(They used to cost about $100 less. See another review on here from Sept 2011, where they were $192... $192 to $279.88... Nice price hike Etymotic!)
However, enough is enough.
Having owned four pairs I can conclusively say these headphones must be designed by Etymotic to fail within a short time frame.
I contacted Etymotics customer services department directly by email to ask them about the build quality, but they never bothered to reply.
So you can draw your own conclusions from that, and the fact that they seem to be doing a thriving business in "$120 repairs"
The fact is that these are expensive $300 headphones and one pair ought to last a minimum of 5 years under normal use.
But they simply don't.
Overall, I would reluctantly have to recommend that you no longer buy these headphones, or that if you do you set aside another $300 for the new pair that you will inevitably need to buy when this pair fails.
It genuinely saddens me to write this review, because the sound is great, but the build quality is very poor and for this money the customers deserve better.
Come on Etymotic. Raise your game!
You have raised your prices. How about now improving the standard of the components in these headphones so they don't consistently fail?
You are letting your customers down.
There are the usual caveats of an in-ear-canal headphone: Ear-canal type headphones like these must be inserted ALL the way down into the ear canal to get good bass. The better the seal the better the bass. One of my ear canals isn't straight and I sometimes have trouble getting that ear's earphone properly positioned. Once I do - the bass on these phones is amazing. This issue causes problems for some. Some people just can't tolerate something in their ears. My wife uses foam earplugs all the time but she's too squeamish to insert these earphones properly. I know plenty of people with this issue. Be honest with yourself about this before you make the plunge. If ear canal type earphones are not inserted all the way to make a good seal they sound tinny and lightweight with no bass.
Then there's the usual caveat for any high-end audio transducer: it's only worth the money if you've made sure the signal you're feeding it can do it justice. If your source material is great you'll thrill to hear all of it. You'll hear things you never heard before, guaranteed. If your source isn't good - you'll hear that too. I suspect this is the source of many of the complaints. There are a lot of people listening to low grade portable players - or to audio files with too much compression. Check out any peer to peer sharing sites and you'll find lots of audio tracks that sound like they were ripped off a poorly tuned AM radio station. If this is your music collection you should probably stick to cheap earbuds that soften and roll off the music. Etymotics will sound glorious if you are using lossless compression or high-bit rate encoding off good source material.
I'm an audiophile. At home I tweak room accoustics, cable types, speaker placement and the like. My lifestyle dictates I end up doing much of my listening on commuter busses, airplanes, subways, and long walks across the city. The Etymotics and my iPod - filled with losslessly compressed tunes gives me an audiophile experience on the road. I frequently hear things on this rig that I don't hear even on my high-resolution home system. This kind of musical satisfaction at this price is astounding - a total bargain. Part of what makes it work so well for passenger transport use is the excellent isolation. These things are earplugs - plain and simple. They cut out ambient noise exactly like earplugs. Be aware that sonic isolation can be dangerous for pedestrians, bikes, drivers, and motorcyclists. You can't hear the car horn that might save your life. I walk NYC streets all the time with these on, but when I jaywalk I'm extra careful to look both ways.
I've used ER-6s for last 3 1/2 years or so and was deeply in love. I'm probably a good candidate for Sensas, Ultimate Ears, or other expensive exotic phones, but decided to upgrade to the ER-4ps on reputation when the ER-6s began to lose some sonic integrity after years of hard use and rough treatment. (I use the ER-6s at the gym now - where they sound great and stay put during vigorous exercise). At first the ER-4p's bass was over-ripe. They need some burn-in time. After 5 hours or so the bass came into line with the rest of the frequencies. It is still extremely strong - sometimes almost overpowering. I find this a rare and desireable trait for headphones. Most phones - even really great phones like Electrostatics or dynamic phones like Grados or Sennheisers have deficient bass. The bass and dynamic prowess of the ER-4p puts them in a different league than the ER-6 - which can sound a bit hard and analytical at times. The ER-4p sounds almost euphonic by comparison. I don't think it actually is euphonic. I've used them for about 75 hours so far and they reveal the source material. They just do so in a beautiful way. If you care about audio quality, can tolerate ear canal type phones, and can feed them high resolution source material, you'll probably fall as deeply in love with the ER-4p as I have.
A word about ergonomics. Some have criticized the ER-4P's microphonic cord and way they stick out of your ear - making them vulnerable to contact with hats and helmets. There is something to this criticism - especially in winter. The ER-4p sticks out of your ears, secured only by the friction fit of the earpiece itself. This can lead to annoying encounters with hats and scarves. It's not so easy to make these headphones happy inside earmuffs or ear covering hats. Etymotic was one of the first in-ear-canal headphones and the design lacks the ergonomic advances of Shure and others - principally the routing of the cord up and around the ear and a thicker, non-microphonic cord covering. I wish Etymotic would consider incorporating these advances. Etymotics have penetratingly transparent sound - transparency (ultimately, fidelity) that is impossible to match anywhere close to this price. I'll put up with the ergonomic issue (which are really only issues in winter - for me).
Follow-up - Last week I had an hour to kill at the airport and a nice salesman let me do a shootout with Shure E3cs, E4cs, E5cs, and Sennheiser CX-300s versus my beloved Etymotic ER-4Ps. I was able to eliminate the Shure E3c and Sennheiser CX-300 immediately - they sounded unacceptably muffled and congested by comparison. The Shure E4c and E5c were more interesting. The E5c had more powerful bass, but was ultimately less transparent than the Etymotic ER-4P. The E4c, however, really gave the Etymotics a run for their money. Shure's E4c had excellent midrange and treble transparency and strong powerful bass. I had to go back and forth between these and the ER-4Ps many times to get a firm fix. The major difference is EQ balance. The Ety ER-4Ps are flatter; the E4cs more tipped up at each extreme, as if you had turned both the treble and bass knobs up. The E4cs had a seductive sweetness in the treble and rich solidity to the bass that was very seductive. I was tempted to put my credit card down. The Etymotic ER-4Ps are less exciting - but ultimately felt a little truer to the music. I'd say both had about equivalent transparency and apparent fidelity. The E4cs are twice the price of ER-4Ps - underscoring Etymotics excellent value. The Shures had a nice wind-up case and, perhaps, better ergonomics, however. Food for thought.
Yet another follow up: a word about the fact that the new ER-4Ps are black and the old ones were blue and red. I imagine that Etymotic stopped making the blue/red cable boot models because people thought it looked funny. Now that they are all an attractive black some mourn the lost functionality of immediately being able to see which one is left and which right at a glance. There is an easy way to do this with the new black ones (I own the black ones BTW). Hold one out in front of you and look for the shiny circle. If you see the shiny circle, stuff it in the ear it's pointing towards. If not, shove it in the other ear. Perhaps my words are not clear, but try it once and you'll immediately see my logic. Once you learn this move you'll never have any issues about which is right or left - except in total darkness. If spotting the shiny circle isn't easy for you, add a drop of nail polish on the right one and you'll be able to grab the right one that way.
Update 1/13/12: I recently purchased and reviewed Ultimate Ears TripleFi 10s and compared them to the ER-4Ps. Here is part of that review:
"How do they stack up against the Etymotic ER-4P specifically? These two headphones are top contenders for best of the non-custom headphones - along with the more expensive Sure offerings. Bottom line they do very well. The UE 3Fi 10s have superior bass to the ER-4Ps and don't give up much in the mid range. They have superior dynamics and larger and more exciting sound stage in general. Treble is close between the two. The Triple Fis actually have slightly better extension in the treble, subjectively, but are a bit more hooded in the low treble. Sounds like a rout, but it isn't. The Etymotic ER-4Ps manage to remain competitive by virtue of their seamless coherence. The ER-4P is a single driver design as opposed to the TripleFi's 3 driver design. That means less air moving, less explosive dynamics, less bass extension and weight. But it also means no crossovers and no integrating the sounds of different drivers into a single sound stage. The Etymotic ER-4Ps thus have no seams. Soundstaging is amazing and the music across the sound stage is in scale and hangs together beautifully; giving the impression of perfect accuracy. The Triple Fis sound subjectively more exciting, pounding and dynamic - but subjectively seem to get some of that via the passive equalization effects of its multi-driver design. Another differentiator is that Etymotics also like to be seated deep. This gives them superior sound isolation. A good 10db or so better than the isolation you get with the Ultimate Ears TripleFi 10. However Etymotic recently raised the price of the ER-4Ps to $300. The value equation has thus been reversed."
The Etymotic ER-4Ps are very special. They still do the seamless coherence and total accuracy thing better than the multi-driver more punchy and dynamic competition from Ultimate Ears and Sure. However there is something quite satisfying about the bass heft and dynamic slam of those UE and Sure phones.
