Why some people don't like these is because it doesn't have the detail, clarity and separation and good highs compared to other iems which are similar price. The main reason I don't like these is due to the really soft highs, which eventually put me off aswell, as it began to sound a bit dark for my personal tastes and the very dodgy mmcx connection. If you spend £15 more, you can get the ninetails which sounds amazing according to some facts and breathtaking reviews. The reason their soo hyped now is because of the tuning customisation, apparently you can change the sound in 9 different ways whilst keeping the excellent technical qualities. Mine is on its way from Ali express!
