Q: Does Groove work with iOS devices (iPhones/iPads)?
A: Only with newer iPads & iPhones that have USB-C ports built-in. If the iPad has a Lightning port the answer is No. This is becauseGroove is a high-performance headphone amplifier and DAC designed to power the most demanding premium headphones. Lightning-only iOS devices simply do not provide enough power for high quality headphone drivers, but the newer USB-C equipped devices do.
