Default Are Coto 9007 reed relays ok for audio ?

I've received a dozen Coto 9007 relays (leftover from a friend's project).

Would it be ok to use those to switch audio signals ? I'm thinking of using the relays for input selection or headphones muting.

Any comment / experience with those ?

Coto relays are very good. I have not used them for audio, but do have considerable experience with them in precision instrumentation. The 9007 is part of the Spartan series, which is a 'cost-reduced' version of the 9000 series. For one thing, rated life is only 100M operations vs 1G operations for the 9000 series. Also, static and dynamic resistance and other specs are not as tightly spec'ed.

Like all electrical components used for audio, opinions vary widely. I would suggest you give them a try.
