Listing ID:

For Sale

I only used these a few times at home. These are similar to the over-ear Custom One Pros in that they have a bass slider mechanism and the decorative faceplate inserts, but are smaller. If the slider switch on the earcups is closed, half open...

First things first...these are very large and heavy AMT driver headphones, not for small heads.
