When I received it, to compare, I first listened to a good little AC / DC on my laptop which is PACS with my Logitech Z305.
Then I plugged this "pregnant" in expecting that this "fart" as much.
And then horror, I found myself with a "trick" spluttering, low zero, low max volume and saturating. I thought I heard the little radio full of paint, dust and others, including my father was using to tinker (and still the sound was more powerful).
At first I thought it was a driver problem or install, but no.
In short, while listening to the radio or the video output of your kayak with your friends, phone calls can be (I have not tested), but for music (and even "not classic") you can forget.
2 stars anyway for what I write in the first line.
