The Earbud Tester: When you don't need the full power of a BK2120A speaker tester, then the more portable BK2132 might be what you are looking for. This little machine is based on the more sophisticated system but it provides only basic testing. It is very fast and easy to set up and use and is especially portable as well, all for a lower price.

If you need a more thorough test with detailed graphs and data you can track over time, take a look at the BK2120A. But if all you need is a quick impedance check and a short check at 3 sensitivity bands, contact me here; the BK2132 might be just what you need.
