Good morning, everyone.
I read an interesting comparison, on the Russian forum player.ru, of the Odin mk3 (aka Odin Thridi) versus the Thror.

With the restriction that the Odin Thridi used in this headphone comparison used the small perforation pads (ECL-02: 0.5 mm holes, instead of the stock pads ECL-01: 1 mm holes; ECL-02 pads reinforcing the bass by about 2 dB, perhaps at the price of less spatialization, and that the Thror used was the prototype of the Thror (the very first Thror manufactured ? )), well the description of these two headphones linked above, and their differences, seems to me fair enough, to have listened to them both.
Roughly speaking, the Thror is more airy than the Odin Thridi, with a more important recoil of the instruments; it has more treble than the Thridi, and it sounds quite clear (Nb: very good snare drum rendering with the Thror).
The Thridi is darker and warmer than the Thror, with a fuller midrange.
The Thror and Thridi are more detailed and transparent than the Audeze LCD2 and 3.
And if we want to situate the Thekk in relation to the Thror and the Thridi (for my appreciation), I would say that the Thekk takes a bit the best of these two headphones: the spatialization of the Thror (layered sound) as well as its aeration and its distance from the instruments; the definition of the Thror and its sense of detail, its finesse.
Compared to the Odin Thridi, the Thekk takes the fullness of the midrange and its bass, while keeping the excellent texture of the Thror in the bass.
Thekk is also less dull (and shortened in the treble) compared to the Thridi, without being brilliant; it is less clear than the Thror (less high midrange put forward, but fuller and denser, like the Thridi).
Otherwise, a particularity of the Kennerton planar headphones (Odin, Thridi, Thekk, Thror) compared to the last Kennerton closed-back electrodynamic headphones (Magni and Gjallarhorn), is their much less dependence on the tightness of the pads for the restitution of the mid-bass : the bass level of the Magni (and Gjallarhorn) decreases considerably if the sealing of the pads is not perfect and if there is not sufficient clamping force; this is not the case with Kennerton planar headphones, except perhaps for the sub-bass.
