Now available by popular request!

After the success of the BAL-M50x, we put the same love and care into the design of an adapter for the also-beloved ATH-M40x headphones.  We're excited to announce the release of the BAL-M40x. 

Available from Amazon as a standalone product or bundled with the ATH-M40x headphones.

Thanks to everyone who requested this!  White version coming soon!
