the claim

Bluetooth audio compression reduces sound quality compared with a wired connection.

the verdict
INSUFFICIENT LEANING
Recorded sources
5 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Bluetooth audio compression reduces sound quality compared with a wired connection?

Unclear. Several sources indicate Bluetooth audio quality is a known concern and that lossy codecs discard audio information, but none directly compares Bluetooth compression against a wired connection to establish reduced sound quality.
