I usually don't like things that aren't all rounders but this might be the exception. Bass is incredible - best in class - great texture, fantastic physicality. Treble response is great too - pretty resolving. There is a noticeable recession in the upper mids, giving these a fairly U/V shaped sound signature - violins, for example, lack a bit of brightness/bite that I would hope for. But unlike other V-shaped IEMs, the mids aren't offensive. Incredibly fun to listen to. Probably the best single DD available. EQ highly recommended. Previously Owned

Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops.

Clean and natural signature with treble emphasis. LOTS of details with airy treble without going overboard (better treble extension vs MK2/MK3). Bass is not as impactful versus MK3 but has better separation. Overall a technical monster, but can be a bit dry due to less mid-bass. Vocals are further vs MK3 and MK2 (not as forward), giving it that open sense of space. MK2 still the best for vocals, but LTD is an endgame all-rounder.

The best Thieaudio I've heard to date. Very close tonality to the Mk3, but with better technical performance, especially in the dynamics and stage departments.
