Review on 🎧 Etymotic Research HF3: High-Fidelity Noise-Isolating In-Ear Earphones with Advanced 3 Button Microphone Control by Carla Johnson

I've been using etymotic headphones to listen to music while traveling for over 10 years. I still have my first two pairs, the original ER6s and a pair of ER4 Micropros, and have only had to change the paraffin filters, which I do every few years. These new HF3s are better than the old ones in two key areas: the cords don't make as much noise when you hit them, and the thicker insulation keeps them from getting tangled when coiled. They also sit with less discomfort in the ears than the older ER6s and are slightly better than the ER4 Micropros with seemingly slightly less background noise cancellation. Another thing I like is that they are not two piece like the ER4 Micropros. Over time, they easily become loose in the connector. I use my HF3s with Android phones with no problem as the HF2 was out of stock when I ordered mine but of course the buttons don't work.
