Learn Swedish: Priset är högt, i och för sig är kvaliteten bra. - The price is high; admittedly the quality is good.

It translates to 'admittedly', 'in and of itself', or 'mind you'. It is used to introduce a contrasting but true point, conceding something that softens the previous statement. In casual text messages or online forums, you will very often see it abbreviated as iofs.

Why is the word order ...är kvaliteten bra instead of ...kvaliteten är bra?

Swedish is a V2 (verb-second) language, meaning the conjugated verb must normally come second in a main clause. Because the phrase i och för sig acts as an adverbial and takes up the entire first position of that second clause, the verb är must come next, pushing the subject kvaliteten to the third position.

How is högt pronounced in this context?

Even though it comes from the adjective hög, the neuter form högt is usually pronounced as if it were spelled with a 'k' sound instead of a 'g'. Changing a voiced 'g' to an unvoiced 'k' before a 't' is a common pronunciation shift in Swedish to make consonant clusters easier to say.

Could I just use men instead of the comma and i och för sig?

Yes, you could simply say Priset är högt, men kvaliteten är bra. However, i och för sig adds a specific nuance of conceding a point, similar to saying 'that being said' in English. Using it correctly makes your conversational Swedish sound much more natural and advanced than just relying on a basic conjunction.
