edit: oh and it is unnecessarily louder by default, more reason to buy for the v shapers. good god.
unnecessarily louder ? do you close your ears when you go to the cinema :) i'm using an amplifier to get even more volume. besides, you can set whatever volume you want. ruk30 has one of the bass performances in this market and probably the best in the price range. same goes for the soundstage & acoustic. it's treble performance is better than a lot of models including 2x priced ckm500 and 3x priced brainwavz s1. the list is expandable...
as i said previously again, it comes with the whole range of frequencies unamped (flat). a lot of earphones in the market comes with certain amplifications. koss kdx100 comes with range 60hz-1khz extremely amplified. brainwavz r1 comes with 2khz amplified (weirdly), ckm500 comes 8-16khz amplified (compared to others). stock earphones comes with samsung s3-s4 also the same with ckm500. solution is simple, you can set the level to your liking with the equalizer, again (in the case you don't like it).
you can't expect an earphone to suit your needs completely. besides every song already has different needs. so, it's already impossible. that's why we have volume controls, equalizers, amplifiers etc. when you set your levels right, it should be ok because koss earphones has wide soundstage, good bass, moderate quality treble & highs. add that a cheap price.
no one says they're the best earphone ever created though. samsung stock earphones i've talked about has better treble for sure. same goes for ostry's. but these are not the only parameters here. ostry is the king of the highs but it lacks on the soundstage and bass side. havi is the king of seperations but it lacks bass, loses agains ostry at highs and very hard to drive. this list is expandable.
since ruk30 has wide acoustic, good bass, not bad treble and finally, good price. i'll consider it as a tremendous earphone. if it's coming with flat frequencies which can be correctable by equalizer or it loses at a certain point to a certain models etc. these are just details for me, overall it's one of the hard to beat earphones.
i didn't used the model you're referring to, by the way. but i've used a lot of models which the community agrees with their worth. even compared to the most better models i've tried, ruk30 is still accomplishes to impress me, because of the above said reasons. i don't like sony's marketing style and their cheapest products like e818lp or ex50lp sucks... the model you've talking about has fakes everywhere which i suppose the result of the marketing choices (like the xiaomi piston). weird company, weird products. but if it is good on some specific parameter, that's ok for me. no one said it must be bad (i didn't).
