Many people in my country are selling those Chinese "Apple" headsets which can be found at eBay for 5$, and their bussiness are looking good So it made me think that there might be a reason that so many people are buying this. So, if any of you have had experienced with those, I have a few questions about them: How is the sound quality? And how is it in comparison to the original Apple's product? If I'll be listening to music loudly, will people around me hear it like they do when I use the original iPhone 3GS headsets? Is the sound quality better \ worse than the headsets you get with the iPhone 3GS? Thanks.
