Product Description








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.

    Etymotics always break from wear and tear
  

*by K***Z on Reviewed in the United States on August 7, 2018*

I loved these headphones but after a little over two years they are broken.  This is the 5th or so pair of various Etymotic headphones I have gone through in about 10 years.  I always kept these in a case and they still went faulty at the area near where the headphones split into each ear (thick black part).  When I jiggle that spot the sound goes in and out in each ear as if it’s loose.Any ideas how to fix?  It’s so disappointing to love a headphone so much but always have them fail after the warranty expires.  Etymotic used to give discounts on replacements but I don’t know what to do when ordering on Amazon.  It feels like a $200+ headphone should last longer than 2 years.

    Etymotic Research ER4S microPro
  

*by A***A on Reviewed in the United States on August 7, 2019*

I've been using Etymotic ER4SR for several years. I very much enjoy the sound quality, noise cancelling effect. Having said that, I've had 3 pair, including the ER4XR, ERP4. To date the cable on everyone of these earbuds have failed. They are only designed to be used at your desk. The cable is just to fragile to use for workouts. Additionally, the SR, XR models do offer a replacement cable at the cost of $50. This is the reason for 4 stars. As a result, I've recently switched to HeadSound H5 bluetooth wireless earbuds to good effect for anything that requires lots of head movement, such as workouts, gardening. The sound quality of these wireless earbuds is surprisingly good, although the bass is slightly boomy. Plus, they don't cost much more than the cord replacement for my Etymotic Research corded earbuds.The Ety on ear buds are my preferred cans for both active as well as critical listening. Especially while traveling on an airplane. The manage to cut out 85% of periferral noise. This the main reason they the preferred cans for workouts at the gym, which usually play their music too loud.

    but I do know a fair bit about good sound. Review- I'll start by addressing a few ...
  

*by L***M on Reviewed in the United States on May 4, 2015*

Background-This will be my second set of MicroPro's.  My first set, lasted me around 6-7 years until they fell out of my pocket on a crowded night downtown, and were lost.  I was devastated, and really couldn't bear the idea of spending the money again, because I really considered them an investment.  But, after a couple months of using some Klipsch Image S4-II's and Kilpsch R6's, which were just sort of kick-around pairs, I decided I absolutely needed to have the Ety's back.  I'm not an audiophile, but I do know a fair bit about good sound.Review-I'll start by addressing a few things I have seen frequently in other reviews:---"Flat" or uninteresting sound"---I "know" what people mean when they say this.  These do have a "cool", and perhaps a slight, but not overt, "brightness" to them. The thing is, the detailed resolution that the ER4P's have makes it impossible for me to go to any of the more "warm" or "colorful" (mostly cheaper) earphones I've tried. It may take some getting used to, but I think anyone who purchases these who has a similar background as myself, and wants REALLY good sound, high isolation, and wants to drive them very frequently direct with only an iPhone, Macbook, or iPad, will come to love these.  I can see how "audiophiles", musicians, studio engineers, etc, may prefer different or more expensive options, but these are really great earphones for $300--so much so that I have bought them twice at around that price.---"Lack of bass"---Yes, compared to perhaps 80% of consumer-oriented earphones (especially cheaper ones like Klipsch and Bose), the bass on the ER4P's will seem underwhelming.  However, the bass that is there, is tight and accurate, with absolutely no boominess.  I really have become accustomed to the sound signature of ER4P's and find that I don't miss the exaggerated bass that most ear/headphones have.  Additionally, it must be said that there will be absolutely NO bass audible whatsoever if the wearer isn't truly getting an adequate seal, and placing the phones deep enough in the ear canal.---"Cables transmit a lot of microphonic noise"---This is also true.  They do, plain and simple.  For me, using the provided clip to attach the plastic "barrel" (where the cord separates into individual L/R cables" is a must.  I always clip this barrel to my shirt or collar, to "lift" the portion of the cable closest to the ears, and relieve it of any tension or it's own weight.  That being said, honestly I run long distances with these in all the time.---"Poor build quality, breaks easily"---Like I said, my first set still worked fine until I lost them.  I did have the cable replaced for free once under warranty, and I think the replacement cable (the current design with the red/blue dot), is better than the original (which had red/blue plastic where it connects to the can).  I take good care of them in general, however, and am very careful never to tug or place strain anywhere on them.  I also wind them neatly and carefully each time when I am done with them, and never "ball them up" or cram them in pockets.  If you don't plan on being able to handle these with at least a reasonable degree of care, then they aren't for you.  They aren't designed to be used in a gym or during active use; more like for when sitting still in a room.  But I use them all the time, and love them.
