Summary: I have a hearing deficit and found the ISpark to work very well on both my cell phone and Walkman. It's a pleasure not having to ask people to keep repeating what they've said on the cellphone. Also, to hear my Walkman clearly and comfortably.
Summary: These are indeed a rare find. I'm glad I went to Office Depot soon enough, because there was three of these beauties left! Now, back to the basics... These are one the best earphones you can get... Indeed! The highs, mids, and lows are not overwhelming, but powerful.
Pros: Mind blowing sound quality for only $16 bucks!
Summary: For being so cheap they really deliver. Love how you don't hear anything but the music, even if there is a lot of sound around you. They might seem a bit un-controlled while listening with the volume on max though. But over all they are superb.
Pros: Really good bass response. Awesome isolation, really good when traveling. Cheap, but can keep up with much more expensive headphones.
Cons: Not so durable cord (or maybe I just were unlucky), and it should have flat cables.
Excerpt: I remember Koss. In the 70s and 80s my dad had a set of headphones that were mind-boggling good. Great sound, excellent built. Very comfortable. I'm a sound junkie and believe that earbuds have a shelf life.
Pros: Durable, Great sound quality
Cons: Cable Could Be Beefier, Cable Could Be Shorter, Cable Tend To Get Tangled
Summary: These are GREAT !! The only regret I have is I bought them on Ebay -_- because they only lasted a year. BUT when I say a year they went through hell and back for 365 days!! Trust me these are great ! They kinda hurt after awhile and you have to almost eat the mic sometime lol but a great buy !
