AKAI EWI5000 Purchased new and stored, with very little use. Inspected by the manufacturer at the end of August 2025. (Inspection Details) Inspection requested in the second half of August 2025. - The battery level was low, so it was sent for inspection. Apparently, the EWI requires regular charging. - Reinstallation of internal sound source data. - Overall operational check. The cost was approximately 8000 yen. Since it was just inspected, the condition is good. It will be shipped in an original Ishibashi Gakki (probably) case. Sorry if I'm mistaken. - I have never used the wireless function. I have not confirmed its functionality. The original box is planned to be listed separately. If you would like shipping in the original box, please comment before purchasing.
