Excerpt: 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.
Pros: Accurate, Flat Response, Good Bass, Good Value, Great Sound
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.
#very pleased, have bought 2 sets before this and will continue to buy them.

Summary: This is now my 3rd pair of these earphones. The design has not changed for many years. I purchased my first set back in 2006. They died in 2010, on to the 2nd set, then, my 3rd were bought at the end of 2014. 4 years may not seem like a long time, but I use these for 2 hours a day, 5 days a week sometimes more on the tube. That is a lot of winding and unwinding the cable. Couple of tips: 1.

Summary: When I first got these I thought they sounded terrible. There was a lot of buzzing and vibration sounds. I used the default earbuds and these were bought to replace old ER earphones where the cable had broken, after careful use. I liked the sound of the old ones but didn't think they were so great as I looked after them carefully but the insulation on the wires wore away quickly.
Summary: I cannot describe how dissapointed I was with these headphones for the first 10 seconds of listening! No bass, hiss, tinny, awful. What on earth could I say to the Mrs? How can I justify the cost when I felt like binning them? I groan if we spend money on anything for the house that isn't necessary - and here I am spending a small fortune on headphones that could have paid for a month's shop!

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....
