Introduced in 1986, the EK is the lowest noise Knowles microphone. Its high electroacoustic sensitivity and low noise make this microphone an excellent choice for applications where space is not an issue. The EK can also be used in directional applications as a matched omni-directional pair.
The FG Series microphone is the world's smallest electret condenser microphone. Its cylindrical shape and compact size provide for superior fit rates. The FG can also be used in directional applications as a matched omni-directional pair. The BFG is an improved version of the FG microphone and offers enhanced PFA performance and power-on reset for instant settling time. Its electrical high pass filter enabling custom corner frequencies makes the BFG ideal for use in directional applications as a matched omni-directional pair.
The TM provides the best combination of performance and size. It boasts performance comparable to the standard EM series, in a package 20% smaller. The TM can also be used in directional applications as a matched omni-directional pair. The BTM is an improved version of the TM microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BTM is ideal in directional applications as a matched omni-directional pair.
The TO is the thinnest omni-directional microphone offered. Its small size is perfect for all applications, especially where space is an issue. The TO can also be used in directional applications as either a matched omni-directional pair, or in the TP series uni-directional / omni-directional pair. The BTO is an improved version of the TO microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BTO is ideal in directional applications as a matched omni-directional pair.

Amplified hybrid circuit provides a telecoil with superior RFI suppression.
5100 series passive telecoils feature a polyurethane coating for optimum environmental protection as well as a vast array of electrical and mounting options to choose from.
Form factors include a miniature design that can be immersed in water to a depth of one meter, and a bellows design for depths to 15 meters. The bellows design may be panel mounted, attached for boom applications and is suitable for outdoor use and repeated submersion.
Knowles balanced-armature, magnetic technology to give high efficiency, stability and reliability.
Knowles' largest and most powerful receiver. With its high efficiency and a 143dB SPL maximum output, the CI receiver provides high acoustic power.
The DFK receiver is two FK receivers joined cover to cover to provide significant reduction in vibration signature while increasing output power by 6dB. Ideal for high gain CIC and ITC applications.
Knowles' balanced-armature, magnetic technology to give high efficiency, stability and reliability. Available with Knowles' FerrofluidTM technology.
Knowles' most versatile and most popular receiver, the ED series powers applications ranging from Standard BTE aids and Mini-BTE aids to Full Concha and Half Concha ITE instruments. The ED is made even more functional by the addition of ferrofluid. Its shock survivability makes it a robust receiver for many applications. FED receivers also damp acoustic peaks and reduce vibration to solve feedback problems and closing issues in ITE hearing instruments.
The staple receiver for modern BTE hearing instruments, the EF series represents a precise balance of output power and compact size. Its length-width-height ratio provides an optimum fit that helps maximize BTE space and layout considerations while still providing superior acoustic output. A full range of Knowles' PantographTM, FerrofluidTM, and Vibration IsolationTM technologies help maximize the EF series use for any BTE instrument design. The FEF receiver brings the advantages of Ferrofluid damping, including reduced receiver vibration and improved shock survivability. These advantages are added to the EF receiver's precise balance of power and compact size. A full range of Knowles' PantographTM and Vibration IsolationTM technologies help maximize the FEF series optimum fit and superior acoustic output.
The standard for in-the-ear receivers, the EH series is the workhorse of numerous ITE and ITC designs. Its broad range of design options featuring various port locations, coil impedances, and damping options - including Knowles' FerrofluidTM technology - means that there is an EH receiver ideal for your ITE or ITC instrument. Ferrofluid provides a damped acoustic response without the wax-clogging problems associated with damping screens. Ferrofluid's additional ability to reduce receiver vibration and hearing instrument feedback means that there is an FEH receiver for your ITE or ITC instrument.
The EJ receiver is two ED receivers joined cover to cover to provide significant reduction in vibration signature while increasing output power by 6dB. Ideal for high gain ITC and BTE applications.
The FC series receiver is an improved output and increased headroom version of the standard EH receiver. Moreover, the FC receiver features rounded corners, resulting in a smaller diagonal cross-section for improved fit rates.
The DTEC Series combines two TEC receiver elements with a single sound port. Case size is equivalent to BK/EF. DTEC provides increased output and reduced vibration compared to a single receiver.
MR Series microphones combine a conventional element with a waterproof bellows assembly. The bellows conducts sound to the element and survives 15m (50 feet) of submersion in water. They may be panel mounted, attached for boom applications and are suitable for outdoor use or repeated submersion.
The FH receiver represents an unprecedented combination of ultra-compact size and high SPL output with efficiencies normally found only in much larger receivers. Available with Knowles' FerrofluidTM technology for reduced vibration, improved shock performance, and reduced wax-clogging problems means easier manufacturing and greater field dependability for ITC and CIC instruments.
