Etymotic ER-4P Portable In-Ear Earphones

100% Positive Reviews
Rated #18 in Universal Fit


Pros: Excellent Detail, Flat Response, Great Isolation

Cons: ER 4S needs a powerful amp, it's hard to fit them in ear canal

I'm surprised that no review has been written about those gems! The ER 4P/S is one of the best IEMs in the market value wise. They are made to last, they isolate like no other IEM and they have a unique flat frequency response which can be easily adjusted if you have a good equalizer or an integrated amp. The ER S will sound best when used with a powerful amp, it will provide an amazing sound stage and wonderful imaging of instruments and players. They can provide life like details of the recording including movements, coughs, breathing and pages turned over depicted with extreme clarity. Highly recommended.


Pros: everything , fast accurate precise bass , cleanest mids , gr8 highs .

Cons: cable , heavy cable , can get uncomfortable . sounds a bit thin .

if you own one , you just are treated with one of the most cleanest sounding earphones in this world , lacks thickness , sounds a bit thin a bit sharp , coloration , bright may be , a bit dark . not the best design , comfort is a personal thing , no comments on that , i am comfortable with deep in-ear fit , but not everyone likes it . isolation is awesome , no one can dare to complain , best in this business .


only complain is the cable , heavy , needs a cable clip , not everyone out there likes thin notes , nor this kind of fast and precise bass , can be easily driven by DAPs like j3 , the package is awesome too , has everything you need , from filters to filter removing kit , gilder tips , foam tips , triple flange tips , a small carry pouch , cable clip , no complains at all , and the newer ones come with a 4pt to 4s converter . what more can you ask for .


what can i say , the best phone i have ever owned . i might have liked thicker notes , a bit more bass , like ue600 , but that will make a different phone , and if you want fun , bass , please stay away .


Pros: Neutral tonal balance, very accurate, very detailed sound,

Cons: Comfort, not suitable for bass-heavy music

I own these canalphones twice. I lost my first pair two years ago and I miss their sound so much so I bought another pairbiggrin.gif.


The sound of these IEMs is very neutral and accurate yet without being analytical, the tonal balance is almost perfect.


They are excellent for rock and classical music, but may not as engaging as some other models for Pop and R&B.


In conclusion, they are one of my favorite IEMs. It is very impressive that after over two decades in the market, they still can hold their own ground against to some more pricey and newer models.


Pros: flat with a roll off in the treble

Cons: needs more treble extension

Imagine the flattest IEM that ever existed, take it and add a roll off to make it less clinical and more musical. You have the ER-4P.

The ER-4P is never harsh sounding, or even clinical... I would classify it as slightly dark sounding despite what many think. The bass hits hard with no noticeable roll off. One of its weaknesses is probably the lack of soundstage, however the pinpoint imaging is very good.

Its major weakness is the treble roll off, but I'm not sure whether I'd call that a weakness as it was somewhat intentional I believe. When compared to the ER-4S, the ER-4P has more body in the sound and a recession in the upper treble... think cymbals and stuff. The ER-4S is also more detailed and the bass is perceived to be less.


Pros: Probably the best single armature IEM

Cons: They're are more stylish options

Nobody's likely to steal these based on their looks alone, which are kind of stylish in a teutonic minimalist sort of way, but it's disappointing when people wearing neon pink plastic get more compliments that you. The plus, of course, is the amazing sound quality. If you don't mind getting hit by the bus you didn't hear, these are the best choice for amped or unamped portable sound; even an iPod can drive them acceptably, and better players like the Sony X can drive them fantastically.


Pros: Isolation is second to none, Sound is very clear and detailed, good build quality and secure fit

Cons: Sound is very analytical, can be uncomfortable to wear for long periods of time.

These headphones give a great fit and outstanding isolation, the sound is very detailed and analytical, perfect if you need to work on tracks in a busy/noisy environment. However, I would not recommend them for casual listening as something like the vsonic gr07 or brainwavz b2 gives a much more enjoyable sound.


Pros: The Original & still the best

Cons: Tips can hurt at first because of deep insert

For a non Custom IEM that has everything in spades you cant go past his guy.

Get the adapter and becomes S model and amped raises the bar again.
