Audio-Technica Double Tie Clip

I use the clip with Audio-Technica AT-829cw. It has an Audio-Technica case style M8. Check and see if AT853 is same style.

According to Audio Technica this clip should fit any of their Audio-Technica case style M8's. The model number that you sent is incorrect they normally have 4 digits for the part number. But yours seems to be an 8 series so it should fit fine.
