"I traded my $300 e4c's in for these that's how much they rock!"5.0 starson by bonedaddy4u1111
Pros: Solid bass performance, doesn't have that "suction" feeling like most "innie" earbuds, very consistent sound.
Cons: Difficult to put in ear at first but oh so worth it!
Summary: If you want want some light weight, inexpensive, easy to sleep in (yes, even if you are a side sleeper), all out sexy ear buds with a killer bass you've found the right ones. I am very picky about my earbuds and have tried several including the "updated" version of these, the SparkPlug. The old saying "Nothing beats an original" applies because I found the new Sparkplugs to be very uncomfortable and could not get over the disturbingly scary suction sound and feeling I received when trying to put those in. With these original Koss Plugs I do not get that at all. The reason is due to the breathable memory foam like cushioning as opposed to a solid (not to mention dangerously long) rubber type insulation. My only complaint is that although the bass sounds very rich and deep it could be a bit tighter sounding. They're also very durable - I've had my pair for over 4 years now and they still fit, sound, and work great. Go with these you'll love them!
