Sensitivity
Output level relative to a specified input

Do you need a separate headphone amplifier?
A separate headphone amplifier is useful when it solves an identified limitation in the existing output, such as insufficient usable level, unsuitable noise performance or a missing connection. Impedance alone does not decide the question. Compare headphone sensitivity with its reference units, the source’s output under the relevant load, and the volume-control range you can actually use.
Speaker specifications: what the numbers tell you
Speaker specifications become useful when you keep their measurement conditions attached. Frequency limits need a tolerance; sensitivity needs an input and distance; impedance changes with frequency. Power handling, maximum output and recommended amplifier power describe different things. Use a specification sheet to identify requirements and unknowns, then check the amplifier and intended installation separately.
