Find out, When My Headphones require the Best Amp?

Know about those situations when you don't want a Headphone Amp:

-Lower Impedance Headphones: With Headphones impedance rating below 80 ohms, you are clear to go without Amp.

-Headphone with Active Noise Cancelling: Headphones with Active Noise Cancellation technology already integrated with an internal amplifier. So, no sense of joining another one i.e. Bose QuietComfort 25 and Plantronics BackBeat Pro & more.
