NL21
True wireless earbuds with balanced sound
About this product
Chinese headphones we sold for a while back when we didn't yet have the resources to design our own. They were decent enough, but since they weren't ours, we didn't want to sell them. Quality varied unnecessarily much. This whole product is here mainly as a curiosity, because we haven't sold these in years and they don't even have warranty anymore. Makes it look like we have more products.
NL21
This was a short-run product from Valco's early days. It's no longer manufactured and isn't available second-hand either.
Technical specifications
- Some Chinese chipset in these, I guess.
