The complete guide
Where this microphone sits if you're building a podcast setup on a budget: the the t.bone SC 440 USB
At £44.99, the the t.bone SC 440 USB sits at the accessible end of the podcasting microphone market, and it is worth being clear-eyed about what that price does and does not buy you.
On the the t.bone SC 440 USB specifically, the t.bone states: With USB connector for direct computer operation; Characteristic: Supercardioid; Frequency range: 20 - 18,000 Hz. At £44.99 it sits in the entry-level tier of this catalogue, and those specific figures (not just the USB connection type) are what should decide whether it fits your setup over another the t.bone model or a different brand at a similar price.
What it reliably buys is a genuine step up from a laptop's built-in microphone or a basic headset mic: dedicated capsule design, a polar pattern chosen for speech rather than general-purpose recording, and (on USB models) a proper analogue-to-digital converter rather than whatever chip happens to be built into your computer.
What it does not buy is the last, smaller gains that separate a good home recording from a studio one — those come from room treatment, consistent mic positioning, and post-production, all of which cost time rather than money and matter more than most beginners expect.
For a first microphone, or a second one for a co-host, the the t.bone SC 440 USB is a sensible place to start: it removes the most obvious quality gap without committing serious budget to a category where the returns diminish quickly past a certain price.
