The world's smallest balanced-armature receiver, the FK series is designed for CIC applications where minimum size and maximum fit rate is needed. Only 0.025cc in total volume, the FK receiver can provide over 123dB SPL output for even the tightest fittings and deepest insertions. The wide bandwidth version pushes the boundaries of high-frequency performance. As part of the TWFK receiver, the WBFK offers the widest bandwidth response of any receiver.
