really?  I really love the 3x after I tried it. Compared to 3DD, these iems have more bass, impact but still shallow, 3DD has deeper bass though less in quality. Oh, the detail in 3x is also good. I'm torn between these and the 3DD.

My dx50 is now keeping booting into the recovery mode, not the firmware anymore, how could I go? (when it comes to recovery, I choose reboot and it again reboot into the recovery)
