EC/FEC Series

Knowles' balanced-armature, magnetic technology to give high efficiency, stability and reliability. Available with Knowles' FerrofluidTM technology.

DFK Series

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' 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.

EF/FEF Series

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.

EH/FEH Series

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.

EJ Series

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.

FC/FFC Series

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.

FJ Series

The FJ receiver is two FH receivers joined cover to cover to provide significant reduction in vibration signature while increasing output power by 6dB. Ideal for high gain CIC, ITE and ITC applications.

GD Series

The GD revolutionizes receiver design to maximize output while minimizing vibration. It is well suited for low-mid power custom, receiver-in-canal, and mini-BTE applications that require the lowest vibration possible. The GD offers best in class vibration performance helping to increase gain before feedback in all applications.

GR Series

Highest performance dual balanced armature receiver, maximizing output per cubic millimeter while minimizing vibration and magnetic radiation. Ideal for mid-high power custom, BTE, and receiver-in-canal hearing instruments.

HC/FHC Series

Knowles balanced-armature, magnetic technology to give high efficiency, stability and reliability. HC Series provides increased low frequency dynamic range in a package size equal to FC.

RAB Series

With its small dimensions and high output, series RAB is ideal for small hearing instruments. RAB provides improved magnetic radiation performance and superior case crush resistance.

FK Series

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.

TEC Series

The TEC combines output comparable to the larger BK receiver in an ultra-thin package. TEC is suitable for multi-element earphone designs.

0009 Connector Sockets

Sockets offer compatibility with all standard programming cable assemblies while offering a variety of tab and flange configurations to satisfy custom installation requirements.

009P Programming Cables

Programming cables can be designed to suit standard or unique interfaces, including SMT socket styles.

9201 Programming Flex Grip with Socket Cables

Improved cable design features increased flexibility and contact durability.

2005 Slide Switch Series

Slide switch design features a fully enclosed housing which minimizes risk of corrosion and contamination.

2800 Push Button Switch Series

Traditional pushbutton design provides lead-in feature for simplified installation and increased durability.

2900 Ultra Miniature Push Button Series

Pushbutton overtravel design enables electrical contact prior to full pushbutton travel for superior mechanical actuation.

5100 Passive Series

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.

5300 Active Series

Amplified hybrid circuit provides a telecoil with superior RFI suppression.

EK Series

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.

EM/BEM Series

The EM is the most popular omni-directional microphone offered. The superior performance of the low noise EM makes it the choice of hearing instrument manufacturers for all hearing instrument sizes. The EM can also be used in directional applications as a matched omni-directional pair. The BEM is an improved version of the EM microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BEM is ideal in directional applications as a matched omni-directional pair.
