Narrative:
When cleared for takeoff at dtw, runway 21C, we heard tower say turn to heading 335 degrees after takeoff. Captain read back 335 degrees. I made takeoff, and turning through 300 degrees, tower asked our heading. When captain replied turning to 335 degrees, controller stated we were to be on a 235 degree heading. We were told to maintain the heading we were on and intercepted the departure. There was no conflict with other traffic. Supplemental information from acn 372533: departure said 'say heading.' we responded 335 degrees assigned. Controller stated 'your mistake, fly 235 degree heading.' I had heard from tower 335 degrees, first officer heard 335 degrees, and I read back 335 degree heading to tower. I don't know what more we can do.

Narrative: WHEN CLRED FOR TKOF AT DTW, RWY 21C, WE HEARD TWR SAY TURN TO HDG 335 DEGS AFTER TKOF. CAPT READ BACK 335 DEGS. I MADE TKOF, AND TURNING THROUGH 300 DEGS, TWR ASKED OUR HDG. WHEN CAPT REPLIED TURNING TO 335 DEGS, CTLR STATED WE WERE TO BE ON A 235 DEG HDG. WE WERE TOLD TO MAINTAIN THE HDG WE WERE ON AND INTERCEPTED THE DEP. THERE WAS NO CONFLICT WITH OTHER TFC. SUPPLEMENTAL INFO FROM ACN 372533: DEP SAID 'SAY HDG.' WE RESPONDED 335 DEGS ASSIGNED. CTLR STATED 'YOUR MISTAKE, FLY 235 DEG HDG.' I HAD HEARD FROM TWR 335 DEGS, FO HEARD 335 DEGS, AND I READ BACK 335 DEG HDG TO TWR. I DON'T KNOW WHAT MORE WE CAN DO.
