Headphones

From my research when I was considering buying the sundaras and from my experience owning them for around a year, I think the build quality issues are blown out of proportion online.

Sure there might be some faulty units here and there but it's not so frequent as it may seem while reading stuff online. The thing is people with bad experiences will write the most about it.

When I got my sundaras I was surprised with the build quality, they feel pretty solid, I was expecting much worse from what I have read online. The cable that everybody says its horrible it's perfectly fine, just not very long. Also they sound amazing, overall it was a great buy as I bought a used pair for 180€.

Try e-mailing hifiman asking for a replacement headband, I hear their costumer support is great and sometimes they give things out for free. There are also other places online you can get a replacement from.
