The biggest practical difference is heating approach: Boundless CF runs hybrid convection while XMAX Starry 4 runs conduction. That changes flavor delivery, vapor density, and how the device responds to slow versus fast draws.
XMAX Starry 4 reaches session-ready temperature in ~15 seconds, while the Boundless CF takes ~30 seconds. That's roughly 15 seconds quicker on the XMAX Starry 4, which is useful if you want shorter, on-demand sessions.
Boundless CF uses hybrid convection heating, while the XMAX Starry 4 uses conduction. Heating style influences flavor profile, vapor density, and how forgiving the device is to draw technique.
Yes, only the XMAX Starry 4 supports pass-through charging. The Boundless CF has to finish charging before you can use it.
Listed prices are close: $100 for the Boundless CF versus $99 for the XMAX Starry 4. Day-to-day price will likely come down to whichever retailer is running a promotion.
