Radioear DD45AA Audiometry Headphones, 2x 6.3 mono jack, with Amplivox caps

Radioear's DD45AA with sound-absorbing Amplivox caps is a DD45/TDH39 circumaural headphone for audiometric testing in the standard audiometric range of 125 Hz - 8 kHz.

It is a renewal of the classic Peltor-based audiometric headphones. One of the most important improvements is the precision in the repeatability of threshold tests, which is now at the same level as the RadioEar DD450. The DD65 v2 offers excellent passive attenuation and features a padded, adjustable soft headband with interchangeable circumaural ear cushions. It includes an extremely durable cable with TINSEL core and gold-plated 6.3 mm jack sockets.
