Seems like a good idea, but: If left plugged in all the time, it will actually increase wear and cyclic forces applied to the 3.5mm socket of the Clip+ during normal handling, for periods where headphones are disconnected, and over the life of the unit this could shorten the life of the socket. (It is a lever sticking out, receiving all sorts of inadvertent applied forces and rotations, during non-operational handling, and it transmits all of that to the socket.)
On the other hand, using the socket as designed incurs wear and tear from plugging/unplugging and rotation of a standard 3.5mm headphone plug.
Is there more cumulative wear and tear on the socket by (a) regular use as designed or (b) leaving this adapter plugged in all the time? Not clear. Would probably take some real testing to get good insight.
One other thing to consider: Generally, the fewer mechanical interconnects in a signal path, the better. Some connectors/adapters can attenuate and/or otherwise degrade the resulting sound quality.
(Personally, I use headphones with 90 degree plug connector, so the 90 degree feature is already taken care of. My Clip+ rides in an Audio-Technica AT-HPP3S Earbud Case, and it would not fit very well with a 90 degree adapter left plugged in to the Clip+ socket, but the naked Clip+ alone fits perfectly. )
Just some other things to consider…but hey, even if the Clip+ 3.5mm socket fails, it probably won’t fail before a couple years of service, and that’s about all I expect from a DAP. (My previous DAP had a failing switch at about 2+ years service, then the display started acting funky…) And don’t forget that the lithium ion battery has a life expectancy of only a few years or less, usually.
