You missed "rather terrible". The other day someone on our sales team did a presentation to the company, and they used the microphone on a $3 headset - I practically couldn't hear half the things they said because the audio was so muffled. This is someone who has calls with people all day!
If you record any audio or make calls with people outside your organisation, for the love of God, please invest in some sort of microphone upgrade. Even the $20 no-name Chinese microphones you get on Amazon are miles better than what is built into laptops.
