It is a model that includes the ear speaker part Lambda Nova CLASSIC and the driver unit part SRM-3. After all, STAX is just an ear speaker, so I have the impression that it has jumped far beyond the realm of headphones. As for the exterior, there are scratches scattered on the top plate of the main body, and there is overall dullness due to use over time. Serial M01450 (Tomonori Asaine)
