I just listened to it via YouTube music.

My M2OW in the living room don't vibrato.

The active LFRs vibrato very nicely.

POS M2OW! To the firepit they go!!

BTW, on the LFRs I can clearly hear the oxygen entering the alveoli and carbon dioxide releasing. Her right lung sounds like it has more capacity. I can also hear two - maybe three - small benign polyps in her bronchial passages.
