Any differences in ADR/OTC costs across brokerages? (e.g., Fidelity, Schwab, eTrade?)

Long term holder of Xioami. Recently saw that Fidelity charges $50 for each trade of Xiaomi. (Really got hammered when Sony split into two companies this year and I sold off the Sony Financial services and had to pay $50 to do it.) Does Schwab (or eTrade) offer lower fees? Many thanks!
