Are Blue Yeti microphones still worth it?

Yes—a Blue Yeti is usually worth it only at the right price.

Typical used price: about $35–$60 for a working standard Blue Yeti.
Typical new price: about $90–$130 if it’s still new-in-box or sold by a retailer.
Good deal: under $40 used or under $80 new.
Walk away if: it’s over $70 used unless it includes a stand, shock mount, boom arm, or you specifically want that model.

It’s still a good plug-and-play USB mic for podcasts, Zoom calls, streaming, voiceovers, and casual demos, especially if you want simple controls and multiple pickup patterns. But it’s also an older design, fairly big, and it can sound overly echoey in untreated rooms. For many buyers now, a newer dynamic USB mic will be a better buy if speech quality in a normal bedroom or office is the priority.

Short caveat: prices move around a lot, so check completed/sold listings before buying.
