Excerpt: I have worn these: - on stage to monitor playing my own instrument = Awesome - in coffee shops to focus on completing work projects while completely blocking out people talking in distracting shrill and loud voices = Success - to monitor video camera audio feed = Not So Good These earbud headphones...
Pros: Comfortable, Compact, Durable, Good Bass, Great Sound, Lightweight, Stylish
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: These are undoubtedly my favourite IEMm of all time. And I think that's saying a lot, because I also own Shure SE535, Sennheiser IE8, and Westone UM3X. ER4-PT simply produces the most clean and accurate sound I've ever heard with an awesome soundstage rarely seen in IEMs.
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.
