Getting the sound right on the Audio Technica ATH-M series headphones was ZMF's most challenging pad project yet. The stock pads utilize a unique airflow pattern that gives the ATH M-series headphones their famous sound.  After trying a half dozen sizes and then numerous airflow configurations, ZMF found that solid exterior panels, and perforated ear-side and interior panels with an angled shape is where it's at! 

These ATH sub pads will keep the punchy bass, and extend the soundstage while slightly reducing peakiness in the ATH M-Series 20/30/40/50 headphones.  And of course they feel amazing!  These also work great on Sony CDR 900ST and MDR7506 headphones
