Here’s what I found out about the FIFINE K683B plus some thoughts about how that matches up / what to watch for with listings like the one you mentioned.
🔍 Verified Specs & What Real Users Say
From multiple sources, here are confirmed features for the K683B:
| Feature | Spec or User-Reported Detail |
| Type / Polar Pattern | USB condenser, cardioid pattern. seamusician.com+2YugaTech+2 |
| Frequency Response | ~ 50 Hz to ~ 17 kHz. seamusician.com+2YugaTech+2 |
| Sensitivity | ≈ -43 dB ±3 dB (at 1 kHz) seamusician.com+1 |
| S/N Ratio (Signal-to-Noise) | ~ 70-78 dB depending on estimate/source. DELENordic.com+2YugaTech+2 |

| Accessories included | Pop filter, desk / tripod stand, cable, manual etc. DELENordic.com+1 |
| Build & Materials | Metal body, reasonably solid build; desk stand is fairly sturdy in reviews. YugaTech+1 |
Some sources also describe features like a gain/volume knob, mute button, headphone monitoring jack, etc. Though in some listings, not all features are always clearly confirmed. seamusician.com+1
⚠️ What to be cautious about / inconsistencies
Some listings over-claim specs (bit-rate / sample-rate etc.). For example, I saw a listing saying “24-bit 192 kHz” for K683B on an Indian site, but the user reviews / other official pages don’t strongly corroborate that high sample-rate in USB mode. Design Info+2seamusician.com+2
Upper frequency response (17 kHz) is a bit below what higher-end mics deliver (which go to ~20-20.5 kHz). Depending on how picky you are about high-end treble, this might matter.
The monitoring jack / mute / gain controls are listed in many sources but sometimes aren't very detailed about how good or responsive they are. Could be less premium feel in knob/buttons etc.
🔍 Matching with the “ananditstore…odoo.com” Listing
Here’s how what I found compares with what you described / what such listings tend to claim:
The features you mentioned (mic + pop filter, gain control, mute, headphone jack, desk stand) align pretty well with what the K683B is advertised to offer in many legitimate sources. So on that front, it's plausible that the listing is trying to sell the genuine K683B (or something very close).
The matching with the Indian listing (DesignInfo etc.) showing “24-bit 192kHz” is a bit suspect / possibly marketing hype or over-stated. Unless there is proof (e.g. user tests) that the particular unit supports that, I'd treat that claim with caution. Design Info
✅ My Assessment: Safe / Legit vs Risky
Given all this, here’s my take:
The K683B is a reasonable mic for what it costs, with many users apparently satisfied with its performance.
A listing that offers the features you listed (pop filter, mute, headphone jack, etc.) could be legit, particularly if the price is not wildly low.
However:
If the listing’s price is much lower than what other reliable Indian / international retailers are offering, that could mean either a bargain or risk (counterfeit / defective / missing features).
The “odoo.com2” domain is suspicious in that it's not clearly the same as AnanditStore’s main domain; could be a mirror, or could be unverified. That raises risk on warranties, authenticity, after-sales service.
