Unfortunately new batches of LCD-i3 have some QC problems.
- sloppy glue marks on sides where both shells are glued together,
- too thick connectors (all cables) which cannot fit in the sockets,
- forcing them into sockets can cause damage of inner plastic shell.
A situation in which the user of a new item must grind the fittings from the start in order to be able to use the product is - to say at least - dissapointing for 900$ product. The same cables from i3 have a tighter fit in iSine series, but still usable. Stock cables from iSine 10 or 20 are fully usable with i3. So there is clearly some problems with oversized connectors at the moment.
The good news is, those issues can be solved somehow.
As for connectors, after grinding and polishing = problem solved. All connectors have firm fit and there is no risk of damages to the headphones. But if you don't want to (or can't) do it and prefer stock sound via jack 3,5 mm or with Reveal, simply consider aftermarket cables.
As for glue marks, it can be masked via toothpick and careful removal of the excessive amount of glue. I understand this is an aftermath for issues with glueing, when shells could dissassemble itself, but still, for 900$ it should not exist.
