XDuoo XP-2 Pro Bluetooth Headphone Amplifier

I truly wish that excellent mechanical potentiometers would find their way into low-cost products, as the low-volume channel imbalance and not-low-enough gain settings make the XP-2Pro marginally suitable for easy to drive IEMs. The noise floor is excellent (inaudibly low), but again I wish for a lower output power mode to allow for much finer volume control for efficient loads.

However, since flexibility is the name of the game, the XP-2Pro succeeds as far more than simply being a ‘good enough’ solution for most needs. Behold the duct tape of the portable audio world! That is if duct tape had flawless build construction, clear and transparent sound, and worked great in almost any situation you use it for.
