Audiophile cufflinks

Today I'm introducing a rather unusual product that is nevertheless extremely practical: the Dust Plugs from Cayin. 

Dust plugs close unused 3.5mm and 4.4mm sockets on DAPs, amplifiers etc. and - as the name suggests - prevent dust from entering.

That may sound mundane at first, but apparently there was such a strong customer need that Cayin quickly decided to build such a product for their customers. 

To me this is an example of excellent customer service, because even though Cayin is unlikely to make much money with these things, they are doing it for their customers. 

"We are doing this as a service to our users. The engraved pattern is borrowed from the volume control knob on N8ii and N7."

I don't know about you, but such dedication to your customers is rare these days and I'm so happy about these little, useful, inexpensive things that I'm writing this blog here!

Incidentally, I didn't choose the heading by chance, because Cayin gave the dust plugs packaging that is actually based on that of cufflinks - a nice little token of love for their customers.
