    Etymotic Research ER-4S reviews

    ER-4S Noise-Attenuating Portable Stereo Earphones is rated 4.2 out of 5 by 6.
    Rated 4 out of 5 by from Best noise suppression of any headphone As a professional Sound Mixer for Films I own and use a wide variety of headphones for critical monitoring. My large, over ear style phones are extremely comfortable and convenient for all day use but lack decent noise suppression. The ER 4S phones offer me amazing isolation from outside noise with very decent sound quality. The phones rely on the flange forming a tight seal in the ear which can cause discomfort at first, but the results are crystal clear full range sound with very little ambient noise intruding. This model is more suitable for the pro user or those who require more accurate or critical monitoring. The P version would suit users looking for more punch in their music on the go. Highly recommended.

    Rated 5 out of 5 by from Best Real-World In-Ear Monitors (IEMs) I bought mine more than 15 years ago from B&H and they are still going strong. Super-small, super-lightweight, terrific and accurate sound quality. Anyone who finds the sound lacking is not putting them far enough into their ears. Reach around the back of your head with your other hand to pull back on your ear while you insert the Etymotic deep into your ear canal, then do the same on the other side. Then TURN DOWN the volume you're used to until you can comfortably hear all the nuances of the music while noticing that fans, computers, talking, traffic and other background noises have virtually disappeared. These IEMs are truly amazing if you're wearing them properly!

    Rated 4 out of 5 by from more is more when relying on reviews primarily for IEM with band, ipod sometimes , checked headfi and lots of reviews in advance. on first use not a positive feeling , holllow and not in line with expectations.however change from default silicon sleeve to foam ( all supplied) and things greatly improve.i think they would benifit from portable amp for ipod and custom ear seats ( not inc) , very uncoloured , nothing added to make it sound better but neutral is what im after as the artist intended and not as the EQ department imagine.

    Rated 4 out of 5 by from Great Headphones These sound fantastic, they have very strong high mid response that can accentuate vocals in a useful way, but makes some recordings a little strident. Physically they fell a bit fragile, with very small, non replaceable cable, for the drivers. It's been fine though. The assortment of tips they come with offered enough options to make them fit well in my very large ear canals.

    Rated 3 out of 5 by from Good sound but not worth it. For the price not good. Very clear and the noise attenuation is great. Good phones but not the best in this category.
