In my personal opinion and based on my review experience of various headphones/earphones (no bias here), I think it's a bad idea for any manufacturer to label their product being specific to some genre or sound application. First of all we all hear sound different, to some degree. Then, we use different sources which greatly affect synergy with different headphones. Also, people switch cables, change eartips, use custom phone ROMs, etc, which all contributes more to further refinement of the sound. Just way too many variables. Yes, there is a fundamental sound signature as intended by manufacturer during the tuning of the product, and that's perhaps what they should mention, leaving it up to a customer to decide which on is more appropriate for their application or hits it closer to their sweet spot... And at the end of the day, if you really feel like being "let down", the product could always be returned or exchanged.
Now, with all that said, I'm pretty sure every manufacturers closely monitors the returns and the reasoning for these returns as well as any on-line complaints about their products. And to be honest, this is the first time I see someone being so vocal, mislead, and let down as I see in this case with Danz03 bashing UMPro50
Usually, people complain about something breaking outside of the warranty or not covered by the warranty. But either way, it's cool that Westone rep is browsing these threads and can get some feedback, both positive and negative. As long as we don't scare him away
