I've decided to splash out and get really good moulded IEMs as I'm tired of the cheap ones I have that keep moving and change the bass dynamic in my ears. When I say splash out I'm still aiming to stay below four figures. Thinking around the £700-£800 mark. So much choice. I'd appreciate opinions on the best for bass players. Is a multi-driver setup always the best? Or better quality two- or three-driver setups? I play fretless on a small worship stage in church with a full band (drums, bass, guitars, keys, vocals) being fed back to the in ear monitors.
