What? No one is judging anything with price. If your budget is 5000, why to settle for inferior products. If I have 5000, why will I purchase 500 GB hard disk instead of 1tb disk? Though I'd you as seller has to sell your stock, that's a different matter altogether.
Man, you mean lower priced products are inferior to the higher priced products? No man, not in the world of audio.
joker has given higher ratings to the popular, tank, gr99, E10, E30, gr02 bass edition and so on and the SQ score of these IEMs are more than the S4 and joker has never recommended S4 to anyone on head-fi. Personal experience, it's a lot more common in India only actually i.e., higher the price the better the product. There is always a law of diminishing returns when it comes to audio.
Anyways my recommendation is given your budget, T-Peos popular(balanced sound) and Tank(warm with enhanced bass sound).
