Etymotic ER-4S Headphones
An audiophile headphone
The package includes ER-4S earphones, cord with stereo plug and adapter, several eartips both flange and foam, filter replaces, shirt clip and a case.
The earphones are so designed that they reduce the noise from the audio. There are eartips with flanges that are used for the same purpose. They are fitted into the ears securely. The correct insertion of the earphones inside the ear makes the sound quality better but if they are not inserted properly, the audio quality is still good.
Additional ear tips are included which includes flanged and foamed ear tips. If the standard ear tips do not go inside the ear well, these ear tips can be used instead. The adapter increases its adaptability with different media and the shirt clip secures them with the shirt without the overhead of handling them. The storing case is a soft zipped pouch which can easily be carried while traveling.
The cable has some issues. Also it takes some time to check which ear tip is well suited for you. The earphones offer poor portability.
