Etymotic ER-4

I use them for 1 year.

Previously I had strong DT770 headphones Hd 25
Report Qualit price is excellent.
I would do this no doubt opt.

I am a drummer and the metal band with which I use works with squence, click, low squence, all the guitars go through pod live. So by the singer and the battery no other source of sound scne. Then the cost is capital of Systm. I emphasize that beginners with sound Etymotic is not flattering at all. Nothing to do with the DT770. It was the dcption total. For use against it s'avre the soundproofing is excellent so that even low volume it is possible to send potatoes to save the ear is really a discipline required. Contribution to music I noticed that this type costs less comfortable surgical allowed to play much in place. Other dtail apprciable, the cable is smooth, shiny and not flexible trs. The beginners also I thought rsultat blah and it does not have a crooked s'emmle not in the clothes. The box comes with is complete with lots of spices to spare. Note that the ER4 is easily disassemble for easy cleaning are.

I use the ER4-PRO version.

The ER4PRO comes in a small suitcase containing the headset itself, a mini-jack adapter => jack, and various tips (at 3 or flying foam). All this comes in a box and well protected in plastic-coated chips.
TIPS

- Flying to 3 blades: very isolated, they are great in very noisy environments. The problem is they are a little big for my ears and I do not support very long time. There is probably a matter of habit, but that's a bit too wide anyway. I previously owned another Etymotic headphones, the ER6 (not ER6i) which came with several tips at 2 and 3 wheels of different thicknesses, so I used the finest that suited me better. They fit perfectly on the headphones of ER4PRO and I will definitely re-use. The ER4PRO comes with several pairs of tips on flying, but they are all identical. Too bad.

- Foam tip: again, there are several pairs of tips, all the same. The foam used is rolled between the fingers to refine it, it is introduced into the ear canal when the foam returns to its intitial size by marrying the contours of the duct. The sensation is much more enjoyable and less painful than with flying. Insulation is however somewhat less, but sufficient unless an extremely noisy. In any case, it is more efficient than traditional headphones.
ISOLATION

To give one telling example, here is what I found:
I take the subway every day, and listening to music in good conditions with regular headphones is simply impossible, unless you turn up the volume so inconsiderate. Otherwise, you miss many details, we hear only half the words, and if only one falls on a musical passage quieter than the others, we hear just anything.

With regular headphones, I put the volume on my MP3 player 20 to 25 (of maximum 40), depending on the initial registration. 25 is significantly stronger than 20. In general, it is rather between 20 and 22.
Now, with earphones as ER4PRO, I put the volume between 12 and 16, usually 13 or 14.

External noises are reduced to the point of no longer hear the ringing of the door or the driver's announcements. In the quietest musical passages, means the bearing still on track, we also hear the screeching of brakes or other loud noises that are uncomfortable without a headphone, but everything here is very attenuated.

By comparison, a volume of 13 or 14 with normal headphones in the subway, I hear a noise and I boiled does not benefit at all from what I hear. Of more outside noise is not mitigated, everything is mixed and fatigue more quickly.
NO MUSIC AT ALL

The simple act of wearing the headphones of ER4PRO can greatly reduce ambient noise, which can be very relaxing. This is particularly significant in aircraft where the noise is constant and can be very tiring in the long run.
SOUND QUALITY

The sound spectrum is faithful, the instruments stand out much from each other, the voices are audible, the bass without being too present put forward (fans refrain bass boost) and treble are present without being flashy. I really like. It's a bit analytical anyway, it is not in the case of headphones flattering, but for me it's a good thing.
CONCLUSION

A good investment. Hard to say if he deserves the prize (more than 200 euros with the delivery, it's still quite something, given that most people are content with headphones less than 20 euros).
I do not have enough experience in the field of in-ear headphones to get into comparisons. What I am certain is that the insulation provided is a big plus, the sound quality is perfect for me and the son (twisted) seem more robust than its little brother the ER6 which unfortunately had a sad end (wire torn as nothing inadvertently ==> irreparable, trash)
