Have these - like them quite a bit. My office is near the cafe, and the noise (noise noise noise - grinch) is completely suppressed when noise canceling is turned on.
Another nice perk is the audio-in jack that can be used if the battery dies and you happen to have a 3.5mm cable around.
Does anyone know how to get them to connect to my laptop? I seem to be doing everything right, then it disconnects immediately.
You have a warranty with COWIN. Have you checked with them for some troubleshooting ideas?
