Pros: works very well with my 1st generation iPhone. Tested on normal mp3 songs and hands free phone calls. Sound is loud and clear, the mic works well too.

Cons: Not much to complaint for goods at this kind of price. The only problem is the silver metalic shield on the earpiece dropped out after first time I used it. I just put a bit of glue and put it back. I did the same to the other shield just in case eventhough it hasn't dropped out. I have the same problem for 2 other China made earpiece too. seems like a common problem for this kind of China made product.

Other Thoughts: this is my 5th pair of eye piece on the same iPhone i have since ~ 2 years ago. first pair is the original one came together with the phone - i lost this one. 2nd pair bought from Apple Store in US but it does last long. The button on the mic cracked open and drop off. the rubber insulating the wires also cracked open and expose the coppers inside. it was still working in such condition but wasn't what i expect for the kind of price i paid to Apple. So i started trying cheap iPhone compatible products. the first one is just normal earpiece without mic. then i got myself a 4th one with mic. it works very well until I accidentally stretched it and broke it into 2 pieces recently.

Bottomline: they work as good as their expensive cousin but 20x cheaper. I happily bought 2 pairs this time with 1 as backup.

Pros: These were very cheap and looked almost identicle to the real thing. The buttons worked perfectly

Cons: The ear peices arent as comfortable as the real headphones. The sound quality I found to be significantly worse and I would only use these for maybe listening to audio books. You get about $4 dollars worth of sound quality IMO.

Other Thoughts: If you just need headphones and you don't care too much about sound quality go for these. I just didn't find the quality to be all that great.

Bottomline: They are cheap so you might as well buy it and see for yourself if the quality is good enough for what you want.

Pros: First pro is that earphones work well.
Second, microphone seems to work as well.
Third, jack fits well into my iPod 2g.
And the last but not least is the price!

Cons: The build quality is pretty poor, even if it looks like original apple earphones, it doesn't feel like the real ones. Cheap plastic, inaccurate edges, wire isn't very soft.
Sound quality isn't good as well, especially on higher volume.

Other Thoughts: I bought it just for the microphone, so as long as it works - I'm happy.

Bottomline: Buy if you need ones, but don't expect that it'll be as the original.

Pros: Is a really good earphone mainly for the price. The sound likes for the original Apple Earphone. And the material used to make the earphone, is fragile but is of good quality. These sounds has balanced, with not of excessive bass or fine sounds. Buy it.

Cons: The material used to make his, is much fragile.
Its a earphone with an cable very much long.
Something is necessary to tighten the tips from the earphone to fit to normal.

Other Thoughts:

Bottomline: Is a very good earphone, for the price, is a good buy. Help with a great sound balance and the volume is very good. Is so good! Buy it. Buy it. Buy it. Buy it. Buy it. Buy it.
