Etymotic Research MicroProâ„¢ ER-4P Consumer Headphones

Pros: Sound, Size, Isolation
Cons: Microphonic Cord, High Price

The Purchase

I had been looking for some new headphones to replace my Sony MDR-D22s. The Sonys sounded fine, but they were too big for me to carry around with my mp3 CD player. The Sonys were also semi-open, meaning that some sound...

Pros: Superb sonics, small package, complete kit, lightweight, better fit among Etymotic products
Cons: Price, getting used to its in ear location, cleaning, learning curve to insert properly

I recently bought an ER6i as my introduction to the Etymotic's line. I was utterly amazed by the improved listening experience it gave. h ttp://www.epinions.com/content _186266979972 Recently, my travel Diva ...

Pros: Excellent sound quality (except cable noise distracts from this)
Cons: High price, comfort and best performance requires custom earpieces (even more $)

I am a frequent flyer (1,000,000+ miles), and I enjoy the advantages of noise-canceling headphones for music, movies, and just sleeping (connecting them to nothing at all). I bought the Etymotic ER-4Ps hoping that they would be worth the high price...

Pros: Exceptional detail. Great at cutting out outside noise.
Cons: In ear, wax build-up, microphonic noise, cost.

I'm a diehard gamer and have been involved in computer-based sound since its inception. I also do a ...

Pros: Beautiful, acurate, detailed, crisp, live sound. Great sonic isolation. Comfortable plugs.
Cons: terrible cord "rub", expensive, gotta get used to the in-ear style

Etymotic ER4S - $330 retail $220 street….. These sounded unbelievable, very comfortable, not too hard to get in the ear, amazingly accurate, very detailed/full/warm/complete sound, decent bass…...no thumping but present, surprising imaging, lots ...

Pros: Great with binaural recordings
Cons: very limited use, bright with stereo recordings

The Etymotic ER4B is the most specialized of Etymotics 3 ear phones. Designed to work with binaural recordings, their equalization circuit compensates for the rolled off high frequencies lost due to the binaural process. These recordings use a dummy head...

Pros: Sound like you oughta hear it
Cons: Pricey, needs more than passive maintenance

Etymotic ER-4P Earphones

I'm writing this review at 24000 feet, plugged into my laptop and listening to B.B. King and Diane Schuur's "Heart to Heart" CD--hearing only the music and, faintly, the white noise of the airplane's flight. I cannot...

Pros: Sound quality, portability, isolation
Cons: Price, but you get what you pay for here.

I purchased my Etymotic ER4P's a week ago. Since then, I have been going through my CD and MD collection non-stop, rediscovering many new tones and intricacies of the music that I had been missing. The quality of the sound coming from these little...

Pros: Can be used with portable players
Cons: Not quite as accurate as the ER4S

The Etymotic ER4P is the newest addition to the fine line of earphones from Etymotic. They are designed to be more efficient than the ER4S so that portable players can drive them to decent listening levels. Portable players have notoriously weak outputs...

Pros: Sound, size, comfort, and isolation
Cons: Microphonic cord

While in search for the perfect earbuds, I stumbled upon these. At first set back by the price, I looked around for some less expensive earphones, but I came back to the er-4p's. I decided to order them, finally. Coming in a white cardboard box...

Pros: Incredible noise reduction capabilities, portability, durability
Cons: In-ear-canal design isn't everyone's cup of tea, require minor maintenance

I researched long and hard before purchasing these, and haven't regretted the comparatively high cost ($269) for a second. Why? Well, to put it simply, these are THE best noise reduction headphones on the market, period. Their simple, battery free pas ...

Pros: The sound... for home, travel and especially airplane use.
Cons: Either you can take having something in your ear or you can't.

First, I would never have found this product if not for Epinions! I was looking to upgrade my early version of the Sony noise-cancelling headphones (model 5)and wanted to get an opinion on the Bose unit. That led me to a review of these.

I...

Pros: great sound in a tiny package perfect for travel
Cons: in canal design is uncomfortable for some

These "in-canal earphones" arrived in a nicely packaged plastic storage box. Anybody who buys these will immediately see that Etymotic intended on delivering a quality product.... and that they did!

The sound is first rate, rivaling...

Pros: Unbeatable for travel, clean sound, very sensitive
Cons: microphonic cable, low bass is absent

Undoubtedly these (or perhaps the ER-4S) are the best headphones for folks who travel frequently. It's half earplug, half headphone. The sound damping is good enough that I sometimes just use them as earplugs on the plane. I really wouldn't want to ...

Pros: Great bass, Crisp Highs and Total, Blissful Silence surround me.
Cons: Discovering how crappy some recording qualities really are.

I'm not an audiophile. Now that you understand this, here goes my review of my Ety ER4P's:

Just got my Ety's a few hours ago. I'm impressed how such rich sound can flow out of a stem no bigger than the head of a pin.
What a strange...
