Open the box and design

Etymotic ER4 are packed in paper boxes quite simple. Information notable first when handling the boxes are the words “MADE IN USA”, a plus point when the initial assessment of the quality of machining compared to other places.

On the box, we can see the logo on proprietary technology of Etymotic ACCU Technology as well as the spectrum of products Etymotic ER4. The airline said that, the product is equipped with this technology, the sound completely flat, not repurposed and the same with audio from recordings to 100%. It could easily see this through Etymotic ER4’s spectrum.

Unexpected is that after opening the box, the inner paper was a box with logo anymore Etymotic plastic containers full accessories and headphones. Etymotic ER4 accompanying accessories can say a lot more, including 3 pairs of rubber tips of 3 and 4 pairs of foam sponge, 1 jack 3.5mm-6.3mm switch, one set of replacement filters and tools, one clothespin and 1 bag with zipper and earphone user manual is very detailed (should read, with instructions to replace the filter). ER4PT longer version 1, you will have more success ER4S adapter from ER4PT anymore.

These accessories are a standard technology will ensure ACCU should not distort the sound, note should not use non-genuine accessories because they can alter the sound of manufacturers. The included accessories are very high retail prices, each pair of foam tips or have $ 14, a filer to 11 dollars and also special adapter ER4PT-ER4S can cost up to 50 dollars. So you need to keep careful these accessories.

Etymotic ER4 headphones sound box is quite small, given the structure of the headphones is also only 1 BA Driver (micro diaphragm technology), sound box made of plastic should be very light and the lower part is made of twisted wires, L-shaped headphone jack anti-submarine off. Overall, Etymotic ER4 looks quite strange and “toxic”, combined with the accessories of good quality and quantity. This headset can be folded into the segment of high-end headphones on the finishing, packaging and accessories.

ER4PT suit personal audio devices while ER4S need a good power devices

When buying a ER4PT, you will be manufacturers bundled an adapter available from ER4PT to ER4S (according to information from the same company will be approximately 86% ER4S – 92%). With impedance and sensitivity difference, ER4S for better parameters, exact same frequency spectrum than the “audio standard” product line which is directed. 10dB difference ER4PT higher form than ER4S form.

Sound quality and experience when using

It is true that the hearing aid products from the company should be very concerned about feeling used, who have small ear canals or small ear cavity will not have any problems. However, there are a few users complain that my wearing these vulnerable nothing to blame in this headset. Despite the negative part protruding outside the box but the stranger was wearing plenty of Etymotic ER4 go sleep on the phenomenon nor thrilling encounter. Ability Etymotic ER4 soundproof but also brings extremely good. The audio from the public environment as much noise on the roads, schools, … are not affected in the process of listening to music. The only point is reprehensible phenomenon microphonic encounter, each time touching wires are heard quite clearly.

With version ER4PT low impedance and high sensitivity, the sound is still very good even when coordinated with conventional music sources such as iPhone 6s but after the addition of the adapter to switch to the audio ER4s become quite bad when listening with less power amp music.

When listening ER4S with a player as good as Aune M2 amp or amp Aune B1 use it more completely meet the general phenomenon of drowning when listening to iPhone 6s and low amp music player like Iriver AK JR.

Etymotic ER4 sound quality of do the writers remember much about the Sennheiser HD800, although it is often compared with more than K701. Because Etymotic ER4 writers that have sound rustic, neutral, full technical and a little light strips slightly Treb quite similar HD800, K701 with middle strip smoother and sweeter than the trend of the Etymotic ER4. Etymotic ER4 mid strip from a neutral tonal range, rustic, not repurposed honed as trends from IEM Shure sound, but also no sensation of dryness, lack of emotion. Singing sweet deep in a Wonderful Tonight Eric Clapton is still inspiring, not gritty like sound of the Phonak 112 mid still trending neutral and most rustic. Highly detailed central strip, peel and accurately represent any notes, any words, from low-mid to upper. However regrettable point is somewhat midrange a bit thin.

Etymotic ER4 bass bands have not so many, stopping in balance, also can say is lacking a little bit of bass. With the real basshead will see shortfalls much about this bass range, also with an audience accustomed to the neutral headphone will not see any problems with Etymotic ER4 bass performance from. Bass still can meet their duties in the tracks.

The amount is not much, but the rich range of quality bass, bass neat, accuracy and good speed. Etymotic ER4 When listening to metal music with fast speeds Deathsquad Revolution – Dragonforce, Etymotic ER4 also handles neat, no-stick phenomenon, accurately to the drum beat. Etymotic ER4’s bass sound is more natural for the accuracy, sub-bass is not pressing or mid, upper bass that keeps all at neutral. This bass is as easy as matching any other kind of music, which is less than the required bass music as dance or EDM bold. Written for being able to appreciate this band’s bass Etymotic ER4 is almost perfect. Many argue that the Etymotic ER4 bass and force of steam lack bass, but Etymotic ER4 transplantation along the B1 Aune Aune M2S and amp, the writer found that 2 this disadvantage is not big problems, improved bass much more, fuller in volume and bass down force is also good.

Through a 3-band audio description above can easily guess that Etymotic ER4 overall sound with excellent detail, emphasis is excellent, any details of tracks were either small dissection Best. Etymotic ER4 with airy soundstage, but did not assess whether the price range is wide but less headphone airy soundstage that is as Etymotic ER4. Good soundstage depth than width. Music space in the Hotel California is still at large, the applause from the audience feel the echoes far from the stage to the point, easy to imagine the vast space in the night music legend performed by The Eagles. Another plus point is that Etymotic ER4 with imaging can put in a good position to be reconstructed 1 instruments clearly and not difficult to sense the location of the sound source.

Summarizing, Etymotic ER4 is the sound quality headphones completely natural, neutral, detailed, almost perfect accuracy. Etymotic ER4’s sound quality can be said that there is no point to blame, at a price not too high, but bring absolutely adequate sound quality, can even say there is no better choice for those who love sound balance and rustic as this. This is also a very good choice for treblehead, fans of Jazz, Rock, Metal, …. A sound rustic, natural but heard the more addictive and more attractive.
