Z1R is quality bass, and the Titan is quantity. I prefer Z1R for those genres

IEMS does NOT need burn in

This Titan is extremely hard to drive for iems, all of my dongle are not able to drive it well and they sounds like cheap iem. I also just bought the HibyR6GenIII for this iem alone and still had distortion at high volume.

It's so weird that when I changed the stock cable to different cable(mestmk2 cable), it sounded little bit better with less distortion compare to stock cable on the m15i. I also tried on my apple dongle, not enough volume and there was a lot of distortion on the right channel. It only sounded...

I also tried my UM Mest Mk2 on m15i and it sounded perfectly so nothing wrong with my dongle. When I tried the Titan on it, it made a lot of bass distortion on the left channel when I increase the volume.

Same here when I pair it with my questyle m15i. Left channel has much less bass and there is a lot of distortion, noise, but the right channel seems fine. This iem only sounds ok when I pair it with my thx 887 desktop amp, but it's still not so good, even worse than some of my cheap moondrop iems.

It only sounds ok when I pair it with my thx 887 desktop amp. Is it really that hard to drive or just a bad QC? My questyle m15i is able to drive a lot of full size headphones even planars easily, but not this tiny iem

I just received this iem today from headphones.com, maybe there was something wrong with my unit. I tried it on my questyle m15i dongle and it sounded terrible, there were a lot of bass distortion and not as clean as you guys described.
