Well not exactly. Inuit is only one of the tribes covered by the Eskimo[-Aleut] term. A Yupik may equally be offended being called Inuit. But it's up to the individual what they prefer to be called. If in doubt, ask them. But if that's the conversation you're having with them, it's already a fail.
OT: We've been using the Sennheiser 280HD and have been quite happy with them. Especially since the GC guy gave us a 2 for 1 deal at about $50.
