Do I need an external amp or DAC dongle to drive these?
Reviewer consensus
Most of the IEMs here, including the Sennheiser IE 200, IE 100 Pro, Shure SE215, and KZ ZS10 Pro, are sensitive enough to run cleanly off a phone dongle or laptop headphone jack. A dedicated dongle DAC mainly helps with noise floor and gives you a clean volume range; it isn't a requirement for the sub-$300 picks in this list.
