The nozzle is realy big in diameter, i dont enjoy wearing these for longer than maybe an hour Max. The sound is too Boomy in the bass and also very Icepicky for me. i had to use heavy EQ to smooth it out on bass and treble. actualy hurts to wear them for me. The quality is Good.

The verdict
Great for gaming, but only for those looking at a bass-rumbling casual action gaming experience. For music listeners, the bass may be too much even for some bass heads. For those who want the bass to take center stage, this IEM is for you.
✓Liked: Bass heavy, Spatial width and depth, Flashy design, Separate cable with inline mic
✕Could be better: Fatiguing bass to some, Annoying to wear for long hours
What a reader who owns the TRUTHEAR Zero:BLUE2 reports after living with it. Owner-reported, checked before publishing; ordered photo-verified first, then newest.
Owner reviews are not paid for, not solicited from specific owners, and not rewritten by us: at most we proofread typos, which is shown on the review’s own page and which the author can undo. The commission SoundGuys may earn on this page comes from retail links, never from owner reviews.
