These magnetic clips suit most lavalier microphones, as they grip the cable (1.5mm -2.5mm diameter range) rather than the microphone body. They have a circular front part 18mm diameter, with the magnet hidden inside the clothing 32mm diameter x 5mm deep. The cable grip rotates, so the clip can be used horizontally or vertically or at an angle. The cable grip point is 5mm from the clothing surface. Available in black or white.
