HotSMD Audio Isolation Transformer, ED8-600 Ohm to 600 Ohm, 1:1, 6-Pin Surface Mount, 10.5 mm, 1250 V AC Hi-Pot
A 600 ohm to 600 ohm audio isolation transformer in a surface mount package. The two windings are 1:1, so the part is a galvanic break in a line level path rather than a matching transformer: the voltage across it stays where it was, and only the ground connection between the two sides disappears. Six gull-wing pins, three to each side, put it on the board like any other SMD part, which is the reason it exists next to the cased parts it replaces.

ZXY-ED8-10 1:1 Audio Isolation Transformer, 600 Ohm to 400 Ohm Line Matching, ED8X10-2.0H Laminated Core, 14mm Package Gull-Wing Terminals
ZXY-ED8-10 is the product name, and ED8X10-2.0H is the model number: ED8X10 indicates the package size, measuring 0.555 inch × 0.313 inch × 0.197 inch; 2.0H indicates a minimum inductance of 2.0 henry. This device has no printed label. The only slight marking is on the bobbin between the core and the clip, which is too small to be discerned in photos and too dark to be photographed against the varnish background; the full model designation appears only in documentation.
