Conclusion: The Etymotic portable in-ear earphones are great when it comes to sound quality, mixing audios and for decisive listening. The noise reduction is excellent. They are the best earphones for live listening.
Pros: The product exceeds in removing the surrounding noise while listening to some audio. The sound quality is as high as you would expect from them. It does not need any batteries. They can be used for any audio device.
Cons: The cable which comes with the earphones is not strong.
Summary: For me, they are the best ever. Maybe someday i'll listen to something 'better'? Well, we'll see.
PD: The Highs can bother some people with their 2k and 8-9k peaks. For me it's fine, but it's because I agree with Etymotic in their intention of tuning these that way, but you can disagree with them.
Pros: Speed, Detail, Bass and Treble extension, Clarity, Effortlessness, SQ in general. I love the Etymotic tuning (Subjectively)
Cons: The Noise Isolation is just incredibly exaggerated for casual listening (but can be good in the right moment and place), Microphonics!
Summary: 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...
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.
Summary: 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.
Summary: 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.
Summary: I own these canalphones twice. I lost my first pair two years ago and I miss their sound so much so I bought another pair.
The sound of these IEMs is very neutral and accurate yet without being analytical, the tonal balance is almost perfect.
Pros: Neutral tonal balance, very accurate, very detailed sound,
Summary: 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 .
Pros: everything , fast accurate precise bass , cleanest mids , gr8 highs .
Cons: cable , heavy cable , can get uncomfortable . sounds a bit thin .
Summary: 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...
Pros: Excellent Detail, Flat Response, Great Isolation
Cons: ER 4S needs a powerful amp, it's hard to fit them in ear canal
Summary: First impression, extreme clarity without being harsh, very bad cable design, people said ER4 lacking bass, either they are are lover of Aurisonics or they didn't get the insertion right with ER4s
Even with P to S adaptor, still deliver great bass. fast, precise and great texture.
Pros: Clarity, Tonal balance, did I said Clarity? complete accessories out of the box
Cons: Worst cable ever, insertion depth has to be precise, sub-par build quality
