I hold a special place in my audiophile heart for KZ. Their ZS3 IEMs were the thing that brought me into the audiophile world. It let me learn about microphonics, how to properly wear IEMs, and other fun things. Sadly, because the ZS3s are deatchable, I lost one of them. Even if I go to higher priced territory, I'll never forget these guys for bringing me on this wuld audiophile ride.
