THX.

The heading says: "Questyle M15i" (i) - but the text says "15" (under "Pros"). I assume it is 15i that you have testet?

There is no volume control on the unit. It that than done on the iPhone?

You’re absolutely right. It is M15i (corrected). It was difficult to keep up with writing ‘i’ at the end of M15 everywhere.

The volume needs to be controlled from the source (PC/Phone). You cannot adjust volume on the dongle.
