Host more than one speaker at a time
The wireless Silent Seminar headphones work on multiple channels which means you can host more than one speaker in the same seminar space and delegates can then choose who they wish to tune in to.
 
Increase engagement
Our Silent Seminar headphones help remove any distractions and surrounding noise, keeping the attention of your delegates for longer - especially in areas liable to sound spill.
 
Lasting all day
The Harry headphones last for up to 10 hours on a full charge so you are good to go all day without needing to worry about recharging leaving you to concentrate on your seminar.
 
Perfect audio
Our Harry headphones and Donkey transmitter are a great set-up and can receive audio from up to 150 meters away with no lag or delay, delivering premium sound to all delegates. 
More features
Power saving mode
Harry headphones will automatically switch off after 10 minutes of not receiving any broadcasted audio which saves their batteries and makes it quick to pack away at the end of your event.
LED lights
Harry has a center LED light showing which channel the headphones are listening to and flashing LED lights on the edge that beat to the music.
Auxiliary socket
When not at a Silent Disco, you can use a 3.5mm Jack Cable to connect Harry to your phone and use him as a standard pair of headphones. You can also connect a set of headphones to a speaker so staff working at an event can hear the music being played.
