Infrared Headphones - for Minivan

[Darth Paul]

Does anyone know where to buy some less expensive IR headphones? We just bought a new minivan with built in DVD, but we have more kids than headphones. Dealership sells them for $70 or $80. They assure me that any IR headphones will work.

Online or local to Calgary will work for me.

Thanks in Advance
