How do I know which receiver my Oticon hearing aid uses?

The part number is printed on the receiver itself, usually near where the wire meets the body of the device, and it is recorded in your fitting notes. Match that number rather than a description, because the same label means different things at different manufacturers and Oticon is no exception. Take a photograph of it before ordering.

Can I fit a more powerful receiver to make it louder?

You can physically attach one on many devices and it is still a bad idea. The hearing aid was programmed to deliver a specific output through a specific receiver, and changing the receiver changes that relationship in a way the programming does not account for. If a device is not loud enough, have it reprogrammed rather than changing the hardware.

Are receivers interchangeable between manufacturers?

No. The connector, the wire and the coding differ between makers, and frequently between model generations from one maker: Phonak SDS 4.0 and SDS 5.0 are different fittings from the same company. A receiver bought for the wrong fitting is not adjustable to fit and cannot be made to work.

Does the length matter as much as the power?

Yes, and it is the part people overlook. The wire length was measured so that the receiver sits correctly in your ear canal with the body of the device sitting correctly behind your ear. A wire that is too long leaves the device hanging loose and a wire that is too short pulls on it, and neither is fixable by adjustment.

How long should a receiver last?

There is no published figure, because it depends overwhelmingly on moisture and earwax rather than on time. Drying the device overnight and changing wax guards on schedule are the two things within anyone control that extend it. A receiver that fails repeatedly in the same ear usually points to wax or moisture rather than to a bad part.

Oticon receiver wires

Quick answer

Oticon uses MiniFit receivers, in lengths measured for each ear. Replacing a receiver means matching the same power, the same length and the same side as the part being removed, because the power was chosen for a fitting the device was then programmed around, and the length was measured for that specific ear.

Which receiver fitting does Oticon use?

On a receiver in canal hearing aid the speaker sits in the ear canal at the end of a thin wire rather than inside the body of the device. That speaker is the receiver, and it is a wearing part: it fails, and it is replaced.

Oticon uses MiniFit receivers, in lengths measured for each ear, across the Oticon receiver in canal range. Oticon wax guards are ProWax MiniFit, which is a different part from the Phonak and Starkey fittings and is not interchangeable with either. Receiver length is measured for a specific ear, so a replacement matches the length as well as the power.

Parts are manufacturer specific and frequently model specific. A part that nearly fits does not seat, which changes both the acoustics and the security of the fit, so match the part number on the component you are replacing rather than a description or a size in millimetres.

Replacing a receiver is a repair, not an upgrade

This matters more than anything else on this page. The power rating on a receiver was chosen to match a fitting, and the hearing aid was then programmed on the assumption that it is there. Fitting a different power changes what the device actually delivers relative to what its programming assumes, and the result is not a considered fitting.

Fitting a more powerful receiver does not make a device better. If more output is genuinely needed, that is a reprogramming appointment with whoever fitted the device, not a hardware purchase.

Receivers are also handed and measured. A left receiver and a right receiver are different parts, and lengths are chosen for a particular ear. The part number printed on the receiver you are removing is the thing to match.

The power ratings, and what they generally cover

Trade convention Taught everywhere in the clinic and the trade, and published as a standard by nobody. Useful, and not a standard.

Power labels differ between manufacturers: some use S, M, P and UP, others use 1 to 4, and the two do not map onto each other.

Receiver power ranges
Power	Typically fitted for	Roughly up to (dB HL)
Standard (S, or 1)	Mild to moderate loss	55
Medium (M, or 2)	Moderate loss	70
Power (P, or 3)	Moderately severe to severe loss	85
Ultra power (UP, or 4)	Severe to profound loss	105

These ranges are a trade convention. The actual output of any receiver is a figure only its manufacturer publishes, and the selection is made against a full audiogram in the manufacturer own fitting software rather than from a chart.
