The microphone is a high quality dynamic cardioid mic with an
ON/OFF/Mute switch, which is an extremely useful feature in live
performances. The Mic also boasts "30 hours off a single AA battery".
That is an impressive claim that AKG are in the unique position of being
able to claim with conviction, the mic really does last an incredibly
long time and this can be a real time, and not to mention, money saver.
The set includes an SR 40 MINI receiver, an HT 40 MINI handheld
transmitter, a universal power supply with US/UK/EU adapter, and one AA
size dry battery. Everything you need comes straight out of the box, so
you can make yourself heard from the get go.
