Does anyone know the name of a heart rate monitor that works with a cable clipped to your ear?

Question

I want to buy one of these heart rate monitors (or probably any kind that takes the reading with a direct cable link), because I have two wireless ones that work from a chest strap and neither gives an accurate reading. I use the monitor when exercising on a stationary exercise bike, so the cable won't be a nuisance.
