But IMO, ый has just a slight, almost undetectable "х" at the end. Like ыих almost.

I don't know if I'm right by saying this, but that's what I hear.
To an extent you're right. With many Russian speakers "й" (if pronounced very clearly and w/o voice at the end of the word) is slightly like "хь" because the places in the mouth where "й" and "хь" (not "x") are formed are close to each other. However, in normal colloquial speech (especially quick speech) hardly anyone pronounces the final "й" so clearly. Most people do it as a very reduced "и."
