Beware of Neumann counterfeit selling on ebay
Counterfeit Neumann microphones, especially popular models like the Neumann TLM 103, Neumann TLM 102, and Neumann TLM 49, have become increasingly prevalent on eBay and other used marketplaces. These fakes are often physically convincing, making them difficult for inexperienced buyers to identify without internal inspection. [1, 2, 3, 4, 5]
Common Warning Signs of Counterfeit Neumanns
• Unusually Low Price: Genuine Neumann microphones are high-value precision tools. Any "new" listing for models like the Neumann TLM 103 or Neumann TLM 102 priced around $200–$300 is almost certainly a scam, as these often retail for significantly more.
• Internal Transformer: Many legitimate Neumann TLM (Transformerless Microphone) models, as the name suggests, do not have a transformer. Opening a fake Neumann TLM 103 often reveals a cheap internal circuit board that incorrectly includes a transformer.
• Weight Discrepancies: Authentic Neumanns are typically heavier due to high-quality milled metal construction. For example, a real Neumann TLM 103 weighs approximately 16 oz, while fakes are often considerably lighter and use cast metal or plastic parts.
• Physical Inconsistencies:
o Neumann Logo/Badge: On authentic units, the diamond-shaped badge is perfectly seated. Fakes may have logos that are rough around the edges, blurred in photos, or even peeling at the corners.
o Mounting Screws: Authentic models usually have screws securing the grill that are flush with the body. Many fakes have recessed or poorly fitted screws.
o Thread Length: Real Neumanns often have only 6–8 threads on the base, whereas fakes may have threading that runs the full length of the base area. [1, 2, 3, 4, 5, 6, 7, 8, 9]
How to Protect Yourself
1. Request Internal Photos: Before purchasing a used mic, ask the seller for high-resolution photos of the circuit board. Authentic units should have the Neumann logo and specific part numbers (e.g., "525981" for a Neumann TLM 103) soldered directly onto the green PCB.
2. Verify Serial Numbers: Contact Neumann Customer Service or Sennheiser Support with the serial number and photos of the capsule and PCB for authentication.
3. Check the Seller: Be wary of sellers who blur logos in photos, re-list the same high-end items repeatedly, or primarily sell unrelated items like auto parts.
4. Use eBay’s Protections: If you suspect you have received a counterfeit, you can file a "not as described" return claim through eBay Customer Service to secure a refund. [1, 2, 3, 4, 5, 6, 7, 8]
