These work great for what I got them for which was bluetooth IEMs with a better microphone that people can actually hear. The only problem is the appearance ; I don't know why but Celest makes some of the ugliest looking products. The odd shiny turquoise in unappealing at best, makes it stick out, and clashes against certain outfits. I have already had people walk up to me and say how ugly it looks.
It works great but it's really an ugly duckling.
I would be certainly happy if there was a different color option.
I think color and appearance is a major problem for many chi-fi products.
Simple non-offensive black or white color options would go a long way for many products.
I understand wanting to make a product stick out but there are better ways to do so like color accents.
Great product though.
