Re: Fact or opinion
You can read it as a factual statement that Sony and Sennheiser both boast of superior audio quality, although [citation needed], and that wouldn't be the ordinary idiomatic meaning.
I suspect that when it comes to "sound quality" statements that it's all subjective based on the listeners perspective and the state of their hearing. For example, I have some hearing loss due to jet engines and race cars and my wife does not have any loss. We hear things "differently" so what works for her, doesn't work for me.
