the NB Sigmas have reminded my why I love NB Lambdas so much and has been my favorite headphone since I got them. I don’t need two sigmas and have listed the 404 Sigmas for sale because the NBs just agree with me a little more (much more mid-focused, sweeter than the 404, etc.).
As for your question it’s a good one and I’d love to hear others thoughts. I think best practice is to NOT do what i do and rest the Plastic, not the band. Neither feel right to me, tbh and I can replace a headband easier or cheaper than a fraMe so I so what I do.
Interestingly, these NB Sigmas came with their own purpose built stand. I’d never seen this before and even after searching it I still don’t see any blue versions so I think the brown fuzz burnt off mine.
Honestly a perfect stand because neither the band nor the plastic frame touched it and there are carve outs for the cable connector area. Came with original manual too, I love those little bits.
