Put ceramic pads on front brakes. They make metallic sound when applied.

Ceramic pads are usually quieter than semi-metallic pads. Especially a Honda. I would take back to shop and have checked.

Just from the viewpoint of what I've seen at the dealership I work at , there aren't to many aftermarket pads (no matter what 'grade/quality' that do not make some squealing if used on Honda OEM rotors. Were the rotors resurfaced prior to pad replacement? That will also make some difference. May need to either go back to OEM pads , or get the 'matched' rotors for the pads you got.
