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.

 Comparison and some other thoughts November 27, 2008
First, I'll give you some background.
I'm a student, a former music major (now Biomed engineer). I take my music and the quality of my experience very seriously. (I.e. - nothing under a 320 bit rate and no ipods)
now, it's not all classical music - but all sorts. you name it, i probably have it.
Here are my two cents about this piece. I myself am one of those people who need the foam piece to get a proper, comfortable fit. But once these bad boys are inserted, you pretty much forget that they are in to begin with.
The experience is awesome. It's just clear and precise. exactly what etymotic was gunning for. They don't care about "maximizing bass" or some stupid stuff like that. It's about pure, unadulterated, music. Basically, you're hearing exactly what the composer/artist wants you to hear. You want the bass? Go crank it up yourself on your eq.
I've tried the Shure e2c, the Senn cx300, and the ue5, etymotic er6, even some overheads like the sony and senn hd. What i can tell you is that each has its own character. (shure - comfortable, more uncontrolled bass, senn - nice, but not as good in all traits, etc.)
The only real competition i saw for the er4 was the ue5, rightfully so, since they are in the same "weight class", but the ue5 just didn't have the same feel of authenticity, clarity, etc. But it have more bass, so much so that at times it distorted/overpowered other tonal regions. If you're gunning for that, go for the ue5 (for those with heavy pop/rock tastes). But if bass doesn't need to be banging on your eardrum, I'd seriously say the er4 is unbeatable.
It's not like the bass is not there with the er4. But again, it's all about authenticity. You're hearing EXACTLY what the artist wants you hear. If that's not good enough for you, take it up with the artist you made the piece.
the only negative i can think of: the wires are funky and most of the time, i need the use of the given clip to get a real comfortable control of the wires. otherwise 5 stars.
ER4P does exactly what they promise November 14, 2008
great sound on highs and mids, just like everyone else here has stated. bass leaves something to be desired. i called etymotic and they sent me a bigger set of foam tips free of charge! would recommend to a friend.
A year along and only positive things to say October 31, 2008
Before I bought these, I did a LOT of research into the various headphones out there. I wanted something that offered great sound, provided complete noise isolation to the outside world, was portable, durable, and didn't cost $1000. I picked these, have had them over a year now, and am very happy with them. I listen to many types of music: rock, classical, rap, vocal, acoustic, etc. and they have been great. Walking through Times Square and only being able to hear a crystal clear Michael Buble singing "Feeling Good" is quite an experience, and these headphones were just the ticket!
Outstanding October 28, 2008
I recently thought I had lost my ER-4Ps, so went through the process of looking at the Shure 530s and the Ultimate Ear Triple.fi 10vi's. At first, the bass in these two competitors wowed me. But after listening to both for a while and then going to my replacement ER-4P's I remembered what had attracted me to the Ety's in the first place. They are smooth, they are light weight, and just plain comfortable in the ears. I don't think you can go wrong with these. I listen to a lot of different music, but mostly classic rock and am satisfied that I made the right choice. Plus these are less than half the cost of the Shures or UEs. Highly recommended!
Great buds, but 5 star is way overrating them. October 27, 2008
I bought these and the ER6i set at the same time. Compared to the ER6i, the ER-4P does have somewhat better response at the low frequencies. However for overall sonic reproduction, my Bose Tri-Ports and Bose QuietComfort 3 headphones far outperform either of the Etymotics.
Here's my take on sound isolation/cancelling. My Bose QuietComfort 3 headphones do great on low frequency sounds (as they are designed to do). However, both of the Etymotic earphones do a much better job in the office environment. (The QuietComfort 3s do nothing to block or cancel office noise--you can only drown it out.) The good seal on the Etymotic earphones blocks sound from the computer fan whine and office conversations (co-worker whine)--even with my iPod set at its lowest volume. The Etymotics are the only earphones or headphones that I listen to with the volume set at minimum.
For my money though (hoping to help someone out here), I would purchase the Etymotic ER6i for decent sound and excellent high-frequency noise blocking. i.e. The extra money spent on the ER-4P bought me little value. However, don't expect either of the Etymotics to block low frequency sound, such as airliner rumble, or to provide superb music reproduction.
Happy Tunes!
