The ER-4PT MicroPro headphones from Etymotic Research provide professional-quality audio in a lightweight and comfortable design ideal for traveling professionals. The headphones use ACCU·Driver balanced armature drivers to produce detailed, realistic audio with better than 86% accuracy from 20Hz to 16kHz. The drivers are precision matched and custom tuned, and also deliver extremely high output sensitivity. The headphones come with an industry-exclusive channel-matching compliance graph that's signed by the Etymotic engineer who matched and tuned the drivers.

In order to provide the best fit for comfort and noise isolation, the headphones come with 7 different types and sizes of interchangeable eartips. Using the proper eartip creates a seal in the ear that provides up to 98% (35-42dB) noise isolation, and also reduces the risk of listening to your audio at unsafe levels. In addition to the supplied tips, a separate CUSTOM·FIT option lets you enjoy fully customized eartips.

The headphones are designed with lasting durability, and feature a braid-reinforced cable for extremely low microphonic effect. The cable has a gold-plated 3.5mm stereo mini plug and 1/4" and dual-prong airplane adapters for use with a variety of consumer and professional audio devices, as well as in-flight entertainment systems. Replaceable ACCU·Filters protect the headphone drivers from ear wax and other debris. Other accessories include a filter tool, shirt clip, travel pouch, and storage box.

          Comments about Etymotic Research ER-4PT MicroPro In-Ear Stereo Headphones:

          I'm an acoustics professional with a pro audio background, and after much research and comparative listening, the ER-4's are the clear winner on the IEM market. The frequency balance is as close to flat as I've found in an IEM and compares favorably to my reference headphones and loudspeakers including HD650's and Focal monitors. The soundstage, isolation, and dynamics are as good as more expensive IEM's I've tried. The only drawback is the physical design and included eartips. Comfort is a personal issue, but I do find that some of the newer IEM designs on the market are much more comfortable and generally ergonomic to use and carry. I can appreciate the utilitarian nature of these, however, and the massive cost savings vs many of those IEM's I think mostly makes up for it. You may just find yourself more likely to want to go custom (as I am about to) than you would with other high-end universals. Even then you'll probably be comparable or a little lower in price, so that's not such a terrible thing really.

          Comments about Etymotic Research ER-4PT MicroPro In-Ear Stereo Headphones:

          I purchased the Etymotic Research ER-4PT because I was going on a plane trip and I wanted the maximum passive noise isolation and the clearest sound reproduction possible. These ER-4PT headphones did not disappoint. Once in the ear, most noise, specially plane engine noise, disappeared and I could hear my music clearly.You will pay a premium for this luxury but it is well worth it since the clarity of sound is awesome. They don't have the extravagant bass that other brands provide, you will hear a true representation of the music: clear highs, mediums, and lows without any extra.The only negative about these headphones is that after a few hours your ears will start to hurt with the flange ear tips. I've tried the others and they are marginally more comfortable. I'm considering splurging for the custom ear tips in order to get a precise fit. Etymotic is one of the only companies that offer this service at this price range!!Overall, these headphones provide excellent, accurate sound which take a while to get used to if you use one of the other exaggerated brands, but pretty soon the true sound will win you over. Highly recommended.

          Most neutral and accurate IEM ever used. Use it with laptop at work and iPod. Sounds better with good lossless source.

              Comments about Etymotic Research ER-4PT MicroPro In-Ear Stereo Headphones:

              I lost my prized HF5's and decided to make the leap to the ER-4pt's. I am pleased with my choice. These have a more robust construction than the HR5s, which felt dainty in comparison. The sound is a little more accurate and immersive than the HR5's. I love to close my eyes and being able to visualizes the musicians playing the individual instruments rather than the coarse overview of the music that I got from every other headphones I have owned. I am very pleased with these accurate, pocket friendly earphones.
