Actually, they do make some wild claims. I asked them about some cables and what to expect if I tried them in my system. They told me I could put them next to some really expensive cables made with exotic materials, and I would hear a tiny difference at best. Most likely, I won't hear any difference. I believe they also make that claim in print on their web site.
I put them in my system and compared them to cables costing a lot more, and the differences were big and unmistakable. Anyone could hear the difference. Blue Jeans cable clearly didn't perform as well as my expensive cables so I label them snake oil. If they were to say our $25 cables can compete with others costing $40 or $50, I would say that sounds reasonable. But up against cost no object cables, they're statements are wildly misleading.
I know better, as I'm sure most of the people here do as well. But a new person just getting into audio could easily be sold on Blue Jeans claims. They don't yet have a point of reference for comparison. So, if they just stay with Blue Jeans cables, they may never realize they're systems full potential. Yes, we all know that some expensive cables are overpriced snake oil, but it has to work both ways. Just because they sell low cost items, doesn't get them off the hook.
