Background:
In addition to being very high quality headphones for general listening, Sennheiser’s HD500A headphones have been designed specifically for use with Therapeutic Listening® music albums. This model features a combination of features and elements from two consumer Sennheiser models (HD500 and HD590), plus modifications to the specifications. The outer shell is identical to that of the HD500, with its supra-aural, open aire design, sturdy construction, and comfortable fit for children and adults alike. The electronic components inside the HD500A contain slight modifications to Sennheiser’s HD590 model, selected for its harmonics and frequency response. The ear cushions are velour like the HD590. See table below for a comparison of the different Sennheiser models.
