Pros Really good design, good bass output, good sound quality, light, good for excercising in some cases.
Cons After prolong use, ears tend to hurt, not good if you wear beanies, hardcore sports use is a no-no.
Pros These headphones have great sound and get very loud. Lightweight and semi comfortable.
Cons If your running or wearing the headphones for a long time they begin to hurt a little bit. And if you run they bounce some and can flip off.
Pros Quality sounds; good bass; comfortable clip-ons that stay put
Cons No replacement ear buds; extension cord too long; main cord too short
Summary I've been using these headphones since 2004 when I bought an iRiver iFP-799 player and ditched the headphones the player came with, and I swear by them. I dig the fact that it clips on my ear so it stays in all kinds of conditions, especially when I go to the gym or run. Sound quality is great, and the bass comes through.
When I finally bought an iPod last year, I only had the player for a couple of months before I decided that I needed a fresh set of earpads. Since I can't get them separately, I decided to buy a new pair of the same model, and found it at a local Sears store. I'm stunned that for all of the advances in headphones in recent years, it seems like sports headphones technology hasn't advanced too far. I'm really pleased that Sony is still putting out this workhorse.
As the reviews state, the headphone's cord was a bit short; it should be at least half a foot longer. The extension cord was way too long, so I ended up buying a short half-foot extension with volume control from Radio Shack and it works nicely.
I'll probably buy noise-canceling headphones in the future, but I think for an all-around sports (and home) environment when I'm on the move it's good to have the headphone open-air so that I can hear my surroundings when need be.
My two cents.
Pros Great sound, espicially the base compact size
Cons Have a tendency to flap around, cord legnth annoying
Summary These headphones are great if you are looking for small, inexpensive headphones with good quality. However they are hard to get them to stay on. Also, the cord legnth can be annoying because the only way it's long enough is with the extension, which makes the whole cord too long.
Pros The bass and treble and just general sound quality are incredible for the small size. They are also lightweight and fairly comfortable once you get used to them. Fairly good price.
Cons These headphones can be uncomfortable at times, and if you exercise heavily, they will flap around, which will make it hard to listen.
