Just got mine through the ENT clinic in our hospital. It consisted of a 10 minute fitting, involving a wax mould of the ear. The earpieces came back two weeks later, and fit very nicely. They even offered mixtures of colors to individualize yours. They came with 4 feet of tubing. I suggest that if you want longer tubing, specify that ahead of time, because it costs about $1/foot. Another option is getting to know a perfusionist. They have some nifty tubing that could be rigged to meet your needs. Total cost can run you $30 to $60, depending on a 'student discount.'
