I've purchased a few IEMs from Amazon and I've never received an open box. That's f*cked up in many ways when it's being sold as new. If you buy direct from Linsoul, HiFiGo, or Shenzhenaudio you shouldn't have a problem like open box but returns are also a pain when ordering from China. It's basically pick your demons because there are pros and cons to both. If you're in the US there is also headphones.com which I prefer to order from if they carry what I'm wanting otherwise I normally just buy from whoever has in stock from the previous mentions.
