Etymotic Research ER4B MicroPro Binaural In-Ear Earphones Review

Average Reviews:

(More customer reviews)I purchased the Etymotic ER-4B's 3 years ago, and when I received them I worried about the durability of the incredibly thin wires. I use these earphones nearly every day with my iPod Nano, and when I turn off the music I wrap the 4B's around the Nano and put them in my jacket pocket. Pretty rough treatment. I felt they would break in 60 days...but they are still in terrific shape.
The sound is great and the noise isolation is phenomenal. I use them instead of my Bose noise cancelling headphones as they are much better than the Bose in isolating you from outside noise, they sound better than the Bose and they take up about 1/10 the space. (BTW, the Bose use a battery to generate a signal that cancels noise, where these "isolate" noise by using the earpiece itself to prevent external noise from entering your ear.)
Sitting in airport gate areas is now a breeze, as I can't hear the screaming kids or guys yelling on their cell phones. Actually, you can hear a little bit of external sound, but it is at such a low level that it is easy to ignore. (Danger: You can easily miss gate announcements, and using them while driving seems unwise, as you can't hear the traffic...e.g, ambulances and trains.)
They are very light and the only real negative (if you don't count price) is that it took a couple of listening sessions to get used to these babies stuck deep into my ears. I had 'sore ears' for several days, but I quickly got used to them. When these break I would not hesitate to buy another pair.
