    For more stable testing, we recommend using an extension cord with a mushroom-shaped ear tip. Make sure that this ear tip inserts completely into the ear canal. Mushroom-shaped ear tips allow you to test ‘hands free’ from the AA222. This reduces the chance of contact noise disturbing the measurement.
