Hearing aid receiver vs. sound tube

Receiver or sound tube: what is the difference?

If you need a replacement part for your hearing aid, it can be confusing to know whether you need a receiver or a sound tube. Many users call both parts “tubes”, but they are not the same. The correct part depends on your hearing aid type, model and how the sound is delivered into your ear.

A sound tube is a hollow tube that carries sound from the hearing aid into the ear. A receiver, on the other hand, is the small speaker unit that produces the sound and sits close to the ear canal. Choosing the right part is important for comfort, fit and sound quality.

What is a sound tube?

A sound tube is a thin, hollow plastic tube used on many behind-the-ear hearing aids. The hearing aid sits behind the ear, and the tube guides the sound from the hearing aid down into the ear. At the end of the tube, there may be a dome or an earmould, depending on the hearing aid fitting.

Sound tubes do not contain a speaker. They simply carry the sound that is already produced inside the hearing aid. This means the tube itself is a passive part, but it still plays an important role in how the hearing aid fits and how clearly the sound reaches the ear.

Common signs that you use a sound tube

  • The part is a hollow plastic tube.
  • The sound comes from the hearing aid body behind the ear.
  • The tube connects the hearing aid to a dome or earmould.
  • The hearing aid is often a BTE model.
  • The tube may become stiff, discoloured or blocked over time.

What is a receiver?

A receiver is the speaker part of a receiver-in-ear or receiver-in-canal hearing aid. The hearing aid body sits behind the ear, but the speaker is placed in or close to the ear canal. A thin wire connects the receiver to the hearing aid.

The receiver is not just a tube. It is an active electronic component that sends amplified sound directly into the ear. This is why receivers are available in different power levels, lengths and left/right versions. They must match the hearing aid model and the hearing aid fitting.

Common signs that you use a receiver

  • The part has a thin wire, not a hollow plastic tube.
  • There is a small speaker unit at the end near the ear.
  • The hearing aid is often called RIC, RIE, RITE or miniRITE.
  • The receiver may have markings for side, length and power.
  • A dome or earmould is attached to the receiver tip.

The main difference between a receiver and a sound tube

The biggest difference is where the sound is produced. With a sound tube, the sound is produced inside the hearing aid body and travels through the hollow tube into the ear. With a receiver, the sound is produced by the small speaker unit inside the ear canal area.

This also means that receivers and sound tubes are not interchangeable. A hearing aid designed for a receiver cannot normally use a standard sound tube, and a hearing aid designed for a sound tube cannot normally use a receiver.

Simple comparison

  • Sound tube: hollow tube that guides sound into the ear.
  • Receiver: small speaker unit that sends sound into the ear.
  • Sound tube hearing aids: often traditional BTE models.
  • Receiver hearing aids: often RIC, RIE, RITE or miniRITE models.
  • Sound tube replacement: mainly about tube type, side and length.
  • Receiver replacement: must match side, length, power level and receiver system.

Why do people confuse receivers and sound tubes?

Receivers and sound tubes can look similar at first because both connect the hearing aid behind the ear to the part that sits in the ear. They are also both thin, curved parts that follow the shape of the ear. This is why many people naturally describe both as a “tube”.

The difference is inside the part. A sound tube is empty and carries sound. A receiver contains a small speaker and is connected by a wire. If you look closely, a receiver usually has a small speaker housing at the end, while a sound tube is more like a transparent or thin plastic channel.

How to know which one your hearing aid uses

The easiest way to check is to look at your hearing aid model and the part that goes into your ear. If the model name includes words such as RIC, RIE, RITE or miniRITE, it usually uses a receiver. If the hearing aid is a traditional BTE model with a clear or thin hollow tube, it may use a sound tube.

You can also look at the part itself. If it is a hollow tube with no electronic speaker unit, it is likely a sound tube. If it has a wire and a small receiver/speaker at the end, it is likely a receiver.

How to identify the right sound tube

If your hearing aid uses a sound tube, you usually need to match the tube type, side and length. Some sound tubes are made for specific hearing aid brands and models, while others are available in different sizes or angles.

The tube may also have small markings that help identify the correct version. When replacing a sound tube, it is best to choose the same type and size as the one you already use. A tube that is too short may pull on the ear, while a tube that is too long may sit loosely or look uneven.

Check this before buying a sound tube

  • The hearing aid brand and model
  • The tube type or system
  • Left or right side
  • Tube length or size
  • Whether it connects to a dome or earmould

Are thin tubes the same as sound tubes?

Yes, thin tubes are a type of sound tube. While a sound tube is a hollow tube that guides sound from the hearing aid into the ear, thin tubes are a slimmer and more discreet version, often used with open-fit behind-the-ear hearing aids. Because open-fit BTE hearing aids are very common today, many users who talk about “hearing aid tubes” are actually referring to thin tubes.

The main difference between thin tubes and traditional thicker tubes is the fitting style. Thin tubes are usually used with small domes or tips that sit in the ear canal and leave the ear more open. This can feel lighter and more discreet, and it is often used for open-fit hearing aids. Thicker sound tubes are more often connected to a custom earmould and are commonly used with traditional BTE hearing aids, especially when a stronger or more closed fitting is needed.

The important point is that both thin tubes and thicker sound tubes are hollow parts. They do not contain a speaker. They only carry sound from the hearing aid body to the ear. A receiver, on the other hand, contains the small speaker unit itself and is connected to the hearing aid by a thin wire. This is why a thin tube and a receiver can look similar at first, but they work in very different ways.

How to identify the right receiver

If your hearing aid uses a receiver, you need to match more details. Receivers are normally available in left and right versions, different wire lengths and different power levels. Some brands also have different receiver systems that are not interchangeable.

Many receivers have colour markings and printed numbers or letters. Blue usually indicates the left ear, while red usually indicates the right ear. The number often refers to wire length, and letters such as LP, MP or HP may indicate receiver power. Other brands use power numbers such as 60, 85 or 100.

Check this before buying a receiver

  • The hearing aid brand and model
  • The receiver system
  • Left or right side
  • Wire length
  • Power level, such as LP, MP, HP or 60, 85, 100
  • Whether it uses a dome or custom earmould

Receiver power: why it matters

Receivers come in different power levels because different hearing losses require different levels of output. For example, some receiver systems use LP, MP and HP to describe low, medium and high power. Other brands use numbers such as 60, 85 and 100.

A higher-power receiver is not automatically better. It must match the way your hearing aids were fitted. If you replace a low-power receiver with a high-power receiver without professional adjustment, the hearing aid may sound too loud, uncomfortable or unbalanced. If you use a receiver that is too weak, it may not provide enough amplification.

When should you replace a sound tube?

A sound tube may need to be replaced when it becomes stiff, yellow, cracked, loose or blocked. Over time, tubes can change shape and become less comfortable. They can also collect moisture, earwax or dirt, which may reduce sound quality.

If your hearing aid sounds weak, check whether the tube is blocked or damaged. Replacing the tube can often improve sound and comfort if the hearing aid itself is still working correctly.

When should you replace a receiver?

A receiver may need to be replaced if the hearing aid sound becomes weak, distorted, intermittent or silent, especially after you have already changed the wax filter and dome. Receiver wires can also become damaged if they are bent, pulled or worn over time.

Before replacing a receiver, always check the simpler parts first. A blocked wax filter, dirty dome or low battery can make the hearing aid sound weak even when the receiver is still working.

Can you replace these parts yourself?

Many sound tubes and receivers can be replaced at home, depending on the hearing aid model. Sound tubes are often simple to remove and attach, while receivers may require a little more care because they are electronic parts.

You usually do not need special tools for many receiver replacements, but this depends on the hearing aid system. If the part does not come off easily, does not click into place or looks different from the original, do not force it. The wrong part can damage the hearing aid or cause poor sound quality.

Common mistakes when choosing between a receiver and a sound tube

  • Ordering a sound tube for a hearing aid that actually uses a receiver.
  • Choosing the correct receiver type but the wrong side.
  • Choosing the correct side but the wrong wire length.
  • Changing receiver power without professional guidance.
  • Assuming all receivers from the same brand fit all models.
  • Forgetting to check the dome or wax filter before replacing the receiver.

What to do if you are unsure

If you are not sure whether you need a receiver or a sound tube, check the markings on your current part. You can also take a close-up photo of the part and the hearing aid model name. This makes it much easier to identify the right spare part.

Useful information includes the hearing aid brand, model, left or right side, any numbers printed on the part and whether the end has a speaker unit or is a hollow tube. With this information, it is usually possible to find the correct replacement more quickly.

Related products for hearing aid care

If the sound from your hearing aid is weak, the receiver or tube may not always be the problem. Earwax, moisture and dirt can also block the sound path. Before replacing larger parts, it can be helpful to check small maintenance parts first.

  • Wax filters help protect receivers from earwax and are often the first thing to check if sound becomes weak.
  • Domes sit in the ear canal and should be replaced when they are dirty, stiff, damaged or loose.
  • Cleaning brushes help remove dry earwax and dirt from small openings and hearing aid parts.
  • Cleaning wipes are useful for quick daily surface cleaning.
  • Drying capsules and drying cups can help reduce moisture overnight.
