Up for sale, my lightly-used pair of PSB M4U4. Purchased from an authorized dealer a few years ago and used very sparingly since. I’ve found I don’t enjoy IEMs and after a few other tries, just went back to over-ear or (gasp!) AirPods. These sound great, though, and are very comfortable!
Comes with original box, 2 cables (one for Apple devices), airplane adapter, all silicone tips (unused), and case. few signs of use, a few mars on the non-remote cable I used (I never used the remote cable) and very light mark or two on the headphone body.
No /new/ foam tips, only the used set of Comply’s I have on there. They’re Mediums. I’ll leave them on to protect the tips, and will wipe them with some alcohol, but you will likely want new ones if you prefer Comply to silicones.
