bid vs bed: hear and say the difference
bid and bed are identical except for one sound: bid has the short i, /ɪ/, and bed has the short e, /e/. Short E opens the jaw about a finger's width more than short I and drops the tongue to mid height; both are quick, so the difference is entirely in how open you are.

Why this pair is hard
Hindi, Urdu, Arabic and Turkish speakers often produce both English vowels at one height, so 'pin' and 'pen' merge. Spanish has a clear e, so the 'pen' side is secure and the 'pin' side drifts up toward 'peen'. Mandarin has no independent short e, so the vowel can wander between the two.
