The complete guide
What you actually get in this bundle, and whether it's worth it over buying separately: the the t.bone MB 88U Dual Bundle
The the t.bone MB 88U Dual Bundle is sold as a bundle, which is worth unpacking rather than assuming it is simply the base microphone with extra boxes. Bundling typically pairs the microphone with the accessories most buyers end up purchasing anyway within their first few weeks — a stand, a pop filter, or a pre-configured desktop mount — at a combined price that is usually lower than buying each piece separately.
On the the t.bone MB 88U Dual Bundle specifically, the t.bone states: With XLR and USB connector; Polar pattern: Cardioid; Frequency range: 20 - 16,000 Hz. At £59.99 it sits in the mid-range tier of this catalogue, and those specific figures (not just the USB + XLR 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.
The value case for a bundle is strongest for a first-time buyer who does not yet own any of that supporting hardware. It is weaker if you already have a boom arm or pop filter from a previous setup, in which case paying for a bundle you'll only use part of is worth comparing against the standalone microphone price.
Check what's actually included against your existing setup before buying: if the the t.bone MB 88U Dual Bundle's bundle contents duplicate hardware you already own, the standalone version of the same microphone may be the better-value choice.
For anyone starting from nothing, though, a bundle removes a second and third purchasing decision (which stand, which pop filter) that otherwise adds friction between deciding to start podcasting and actually recording an episode.
