"Good isolation, poor sound quality"3.0 starson by kingfelix
Pros: Best isolation under $50
Cons: Mediocre comfort, mediocre sound quality
Summary: These headphones isolate you from outside noise by using a rather large earplug (with a hole that pipes in sound). Unfortunately, they don't sound very good. They're not unlistenable, they're just very mediocre, and the earplugs may be uncomfortable for some. There are other headphones, such as the slightly more expensive Panasonic HJE50, which give you somewhat less isolation than the Plug, but which sound pretty good. I'd hesitate to recommend the Plug for anything but plane flights or listening to the spoken word.
