Excerpt: 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.
Pros: Durable, Good Value, Great Sound, Lightweight, Optional Custom Ear Tips, Stylish
Excerpt: 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.

Summary: All the 5 stars are right I. On my third pair and I am 44. And had so many pairs of earphones incl. recently from Sennheiser ( IE 8 best for bass if you like thumbing DnB music ) and SONY and Bose ( both good companies and well designed mid range good earphones I use as back ups. ) but if you like PURE quality of sound.....music like Classical with Bach solo violin partitias or Opera sopranos these can give you goosebumps....
Summary: These IEM's are a true revelation! I am listening mostly to classical music, both in the concert hall and on CD's and digital music media. So I have a lot of experience with headphones, both on ears as in ears. The problem with most headphones is the exaggeration of the bass, mostly represented by a sort of rumbling in your ears, created by the headphone-manufacturer to give you a so called real bass experience. You never feel this in the concert hall.
