Summary: I use these as both headphones and a cellphone headset. They are very high quality and produce good sound. The earbuds themselves are a little clunky. And, after a few years of abuse, the rubber lining can crack, but overall they are very worth it.
Pros: Comfortable, Compact, Durable, Good Bass, Good Value, Great Sound
Summary: More comfortable than E5s that I've had for years. Similar uncolored sound; maybe just a bit of treble boost but not annoying. More comfortable. Fall asleep with them most nights. A steal at [$] on sale.
Pros: Comfortable, Compact, Good Bass, Good Value, Great Sound, Lightweight, Stylish
