ShureBLX14 Headset System With SM31 Headset Microphone Band H10
Independent shopping perspective
The Korena take
This H10 headset system combines a BLX4 single-channel receiver, BLX1 bodypack, and SM31FH cardioid condenser headset mic. Its moisture-repelling headset construction makes the configuration especially relevant to fitness instruction. The bodypack uses a hard on/off switch, continuously adjustable gain, and a bi-color battery-status LED; two AA batteries provide up to 14 hours of operation. A power supply, headset windscreens, and user guide are part of the package.
Strong match
Who this is for
- Fitness instruction where a headset microphone with moisture-repelling construction is needed.
- Wireless headset use that benefits from a bodypack with adjustable gain and a hard power switch.
Consider the trade-offs
When to look elsewhere
- Applications requiring more than one wireless channel from the included BLX4 receiver.
