It's happened to me. I imagine a lot of folks around here may not even want to admit this. The biggest one for me was the Sony MDR-Z7M2. I had that headphone for about a month before the reviews started rolling in. And I enjoyed that headphone quite a bit up until that point. You can see the progression of this play out perfectly in the MDR-Z7M2 here thread on Head-Fi. I buy it and sing its' praises almost daily in that thread for weeks, defending its' honor against all naysayers LOL. Then merely a few days after reviews start coming in, especially the Zeos review, I proclaim the MDR-1AM2 to sound better to me and announce I am sending this thing back to Amazon and using it to fund the Sony IER-M9. A complete 180 on my opinion and the only thing that changed was me reading/watching negative reviews. I suppose the question here, as it pertains to sound science, is: did these reviews merely open my eyes to the faults of this headphone? Or did these negative reviews simply implant a negative bias that made me unable to enjoy a headphone I'd literally JUST spent $900 on? What do you all think? Can you relate to this at all? Have a similar experience?
