I rarely use IEMs nowadays, since I hardly have time to sleep, much less critically enjoy music anymore. So regretfully I've been selling my gear. The FXA7 is in great condition, and comes with all tips and the cleaner. I'd like to keep the earplugs for when I go to concerts though.
Signature wise, the FXA7 sounds virtually identical to the ASG-2.5 and Harmony.
I'll ship worldwide at the buyer's expense, but if you live here in 'Murrica then it ships free.
