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.
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.
Summary: Fantastic clarity and well worth the price. I have £500 + in ear phones and these are still my goto. If you want to listen to music how it was recorded buy these. Fantastic sound and a really long lead.
Summary: Like many, I have owned a wide range of IEMs over the years ranging from £20 to £200+. Without question, the best pair for pure sound quality were my Etymotic HF3's thought I bought about 3 years ago.

Summary: The best and most naturally sounding Etymotics I ever had. Accurate,articulate bass and supreme mids.Very comfortable if inserted properly,excellent sound insulation and very well packaged.No frills,well above average made quality.Fully recommended!
Summary: I bought the equivalent of these ten years ago and have enjoyed a happy decade of high quality audio until the wires started to appear at the jack end and decided it was time to renew. These are an improvement on my old Etymotics.
These new ones are perfect and even include an adapter that flattens the frequency ...

Summary: This is my second pair. I managed to decapitate the plug on the old pair after 5 years of constant use. I soldered on a new plug but the earphones were never quite the same... These new ones are perfect and even include an adapter that flattens the frequency response at the higher end to compensate...
