Hello,

I'm wondering if anyone has advice on using 2 or more wireless headphones simultaneously. I'm looking to stage a 'Silent Disco' using 100 wireless headphones, I'm looking at purchasing some 900mhz 150 ft range headphones.

I'm worrying about functionality, does anyone have knowledge of if this will work if they are all on one FM channel, or will I run into problems.. any help or advice would be helpful as I am green on this topic.

Thank you so very much,

Dominic.

you can have as many headphones as you like recieving the signal from the one base transmiter. You might find 900mhz a problem though as UK and Ireland window is 830mhz to 860mhz. Also 100 wireless headphones = 200 rechargable batteries. I'd recommend sennheiser RS-120's or RS-130's.
You get the rechargable batteries free with them.

You could buy one Pair of RS-130's and buy the headphones seperate.
HDR-130's. Will save you having 99 spare transmiters.

According to Sennheisers web site, the RS130s run at 926mhz upto 100m or 864mhz at 150m.

That's actually not quite correct.

A different variant of rs-130's will receive on 926Mhz.
You have to buy the RCA wired version of the TR-130 and the 926Mhz version of the HDR-130's. Product number 009933.

These together will let you transmit and receive on 926Mhz.
Standard RS-130's will not, they only operate on 864Mhz.

You would have to get a shop to specially order in these variant of headset from Sennheiser germany.
