The Cloud II is also pretty good and the headset can be used in regular audio as well as with the USB adapter. Just be warned though the Cloud II has a single mini phono plug for mic and headphones. This means there are 4 contacts on a single plug rather than two plugs with 3 contacts (headphones) and 2 contacts (mic). So if your audio card has separate speaker out and microphone jacks, you'll need an adapter that goes from the single plug and breaks out two plugs. Of course if you use the USB adapter this isn't an issue.
The single mini phono plug design is great to use with cellphones and laptops (which often just have the one jack).
