General

As a self-respecting sport instructor, you're probably moving a lot already and want to give your voice a bit of a break. But because you're moving a lot, a headset system able to withstand the stress involved can be hard to come by. Here, Shure offer a three-part solution in the form of the BLX14/SM31 system. You get a compact BLX1 beltpack transmitter, a BLX4 receiver, and a SM31FH headset microphone. The bodypack weighs a mere 75 grams and offers up to 14 hours of operation on two AA batteries, and the receiver comes with built-in antennas to ensure consistently clear reception. The headset meanwhile, has been specifically designed to take a few knocks, has been fitted with a transparent sounding condenser microphone, is extra lightweight, and thankfully moisture resistant.

Wrote the following about Shure BLX14E/SM31-H8E Wireless Headset System (518 - 542MHz)

Top setje, handig in gebruik, en je moet niet eindeloos naar welke microfoon bij welke beltpack hoort, en al helemaal niet welke beltpack bij welke ontvanger.

de functie 'automatisch zoeken naar vrije frequenties' is ook echt een meerwaarde
