Product Review

Amazon.com Product Description

The ER-4P MicroPro noise-blocking earphones from Etymotic Research offer realistic sound reproduction and noise isolation that far surpasses that of active noise-canceling earphones. The ER-4P earphones--which require no batteries--can be plugged into any audio source. They can be used with portable CD, MP3, DVD, and other players without an additional amplifier.

The ER-4P earphones were designed to match the response of the ear, creating nearly perfect sound reproduction. They reduce external sound naturally by sealing your ear canals, without the added weight, bulk, or external power supply required for active noise-canceling. Their external noise exclusion (up to 33 dB using the supplied 3-flange eartips and 41 dB with foam eartips) lets you hear the full dynamic range of recordings without your having to play them at unnaturally high and unsafe levels.

What's in the Box
ER-4P MicroPro earphones, a 5-foot cord with 3.5 mm stereo phone plug, a .25-inch stereo phone adapter plug, six 3-flange eartips, 10 foam eartips, a filter-changing tool, 4 replacement filters, a shirt clip, a zippered pouch, a storage box, a user's manual, and warranty information.

Summary: Not up to expectations 2008-10-06
Comment: I was looking for a better pair of earphones and this is not it. Bass was washed out. Performance is not worth the price. I ended up returning them because the performance was so bad.

Summary: Great sound isolation, Okay sound 2008-10-05
Comment: I've had my ER-4Ps for over a year. I bought them so that I could concentrate even when there were all sorts of noises around - I've got two kids. These earphones have done a great job. I usually use them so that the kids can watch tv or play while I read or work on my computer. I can literally not hear the tv that's only ten feet away with these in my ears.

The earphones took some getting used to because in order to get the seal to isolate the sound, they put more pressure on your ear canal than other types of ear buds and they also need to be inserted deeper than other types. If you don't insert them correctly the sound quality is terrible and the sound isolation just isn't there. Regardless, with some practice and time to get used to the feel, I've grown to love them. I only use the foam ear plugs because they are more comfortable to me and they block out more noise. I still have not gotten used to the silicone plugs.

The down side of these ear plugs is that the sound quality isn't as rich and detailed as I would have expected. Don't get me wrong, they sound good but not as good as I expect for the price. My stock earphones on my old Sansa provide more richness in mid-range and bass.

Summary: if you want good sound isolation, these earphones rock. If you want high fidelity, look elsewhere.

Summary: Great sound... But that's it. 2008-09-25
Comment: Pros: Great sound, probably the best I've heard in a headphone.
Cons: Everything else.

I mean, really. I was a little surprised to open up the box and see these headphones in there. They look more or less like something that is put together by a 12 year old. Cheap and nondurable is what came to my mind.

Another issue i've had with them is that you cannot put the cord over your ear, which insures that the headphone will stay in. They look goofy when you have them in, due to the cable being almost always erect and sticking out. I don't understand why they weren't engineered to go over the ears. For this sum of money I believe these are definitely not worth it.

Summary: They sound great, but everything else is surpassed by other headphones and better engineering.

Summary: Excellent sound and design for headphones 2008-09-23
Comment: I misplaced my Shure headphones so asked around and one of my friends recommended the Etymotics. While the sound quality from the Shure was very good (using foam inserts) they would tend to pop out during heavy exercise and the cord was too short and not well designed. The Etymotics solve this problem and more. Better noise reduction, as good or better sound and a far better design both on the cord and the three level plastic insert into the ear. It makes a tight seal to keep noise out and music in and doesn't fall out with movement, sweat or exercise. At first, it hurt a bit but moistening the headphones seemed to solve that problem. Overall, I like them a lot and am happy I made the switch.

Summary: Good earphones, but costly and not the best 2008-09-11
Comment: Good high definition earphones, however value/price ratio is suffering...

Problems: Sound is somewhat not very live; not enough bass - even for classical music.
The "noisy" cord problem really kills the thing.
