Used these on a few panel discussions, not really that impressed overall.
OK, they are a budget option, and they certainly feel like they're well made. The finish is good, and they look like they're last.
The pickup pattern is good, and they sound OK, however there seems to be a fair bit of difference in sound between the 6 I bought, and the background noise from them is high.
They'd be fine if you always had good strong speakers using them, but, as is nearly always the case in conference work someone always shys away from the mic, or has a quiet speaking voice.
