Felicity under certain contexts: "Every X seems/sounds like + clause"

Hi, I have a question about the sentences and their contexts in (1) and (2) (contexts are in italics).

I'd like to know whether or not each sentence is good under the contexts given. (The a-contexts are related to direct perception, while the b-contexts are related to report or hearsay.)

I guess (1a) and (2a) are good but (2b) is bad. But I can't tell whether (1b) is good or not.

This is just my intuition as a non-native speaker so I'm really not sure, which is why I thought I'd ask.

(You might think there're better alternative sentences, but I have to examine these sentences in particular.)

Thank you in advance.

(1a)

John works at a nursery school. Children are currently watching an MLB game on TV, and he sees boys getting excited and imitating players’ moves. John says:

Every boy seems like he wants to be a professional baseball player.

(1b)

Mary works at a nursery school. Children are currently watching an MLB game on TV, and she sees boys getting excited and imitating players’ moves. She then gets a phone call from John, and reports to him how the boys are doing. Then John says as a reply:

Every boy seems like he wants to be a professional baseball player.

(2a)

John and Mary are in a meeting, listening to presentations by other committee members. But for some reason, their voice sounds different from usual. Then John says to Mary:

Everyone sounds like they have a blocked nose.

(2b)

Mary just finished a meeting. In the meeting, she listened to presentations by other committee members. But for some reason, their voice sounded different from usual. Mary calls John to tell him the topics the members discussed, mentioning that the members sounded different from usual. Hearing this, John says:

Everyone sounds like they had a blocked nose.

[Note: I'm aware that there's a debate on whether we should use a plural pronoun to refer to noun phrases modified by "every".]
