What's the Difference Between the DD65 & DD45 Headset?

The DD65 is a circumaural headset that fits around the ears. (The DD45 is a supra-aural headset.) On the DD65 V2, there is less pinna pressure, and the headset offers increased attenuation for especially noisy environments. There is one cord that attaches to one side as opposed to a split cable that connects to each transducer/speaker.

Here is a video on our MAICO US YouTube channel that shows the DD45 vs the DD65 v2: https://youtu.be/lLXWU0v0Jt8
