Short answer

Dominant eleventh chords sound wide and suspended. The eleventh sits a half step above the major third that would normally anchor the chord, a clash sharp enough that the third is left out entirely and the fifth, seventh, ninth and eleventh do the talking.

How to use the C♭11 chord

The C♭11 chord is built from a root, a perfect fifth, a minor seventh, a major ninth and a perfect eleventh. Start at the root C♭ and stack the intervals to get the whole chord: C♭, G♭, B𝄫, D♭ and F♭. The same formula gives you the chord in any other key.

Dominant eleventh chords show up in modal jazz and gospel as a suspended, unresolved colour, often standing in for a sus4 with extra shimmer on top. They work best in slow-moving vamps rather than fast cadences.

Where C♭11 is used

A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.
