The main types of hearing aid are receiver-in-canal or receiver-in-the-ear devices, behind-the-ear aids, in-the-ear aids and smaller in-the-canal or invisible styles. None is automatically best. The appropriate style depends on your hearing prescription, ear health, comfort, dexterity, eyesight, listening goals and the features you actually need.
Start with a proper hearing assessment, then compare clinically suitable styles. Size and appearance matter, but a discreet aid that is difficult to insert, underpowered or missing a useful feature is not a good compromise.
Hearing-aid styles at a glance
| Style | Where it sits | Common strengths | Points to consider |
|---|---|---|---|
| RIC or RITE | Small case behind the ear, receiver in the ear canal | Discreet, flexible, widely suitable | Receiver and dome sit in the canal; handling still matters |
| BTE | Case behind the ear, connected to tubing or an earmould | Robust, easy to handle, broad power range | Usually more visible |
| ITE | Custom shell in the outer ear | Controls may be easier to handle | More visible from the side; ear shape and wax matter |
| ITC | Custom shell partly in the canal | Smaller and less visible | Less room for controls and battery |
| CIC or IIC | Deep in the canal | Very discreet | Can be fiddly and may not suit every hearing loss or ear |
| CROS or BiCROS | Devices on both sides route sound to the better ear | An option for some asymmetric losses | Does not restore normal two-eared hearing or sound location |
The NHS hearing-aid guide and the FDA description of hearing-aid styles use slightly different abbreviations, but describe the same broad families.
Receiver-in-canal hearing aids
Receiver-in-canal, RIC, and receiver-in-the-ear, RITE, usually describe the same arrangement. A small case containing the microphones and processor sits behind the ear. A thin wire connects it to the receiver, or speaker, in the ear canal.
RIC devices are popular because they can combine a relatively discreet appearance with useful power and modern connectivity. Different receivers, domes or custom earpieces may allow the same basic style to support a range of prescriptions.
They may suit someone who wants:
- A small device without placing all the electronics inside the ear.
- Rechargeable options and phone connectivity.
- An open fitting where clinically appropriate.
- Flexibility if the prescription changes.
They still need to fit the ear correctly. Wax, moisture, ear-canal shape and the ability to insert the receiver all influence whether this style is practical.
Behind-the-ear hearing aids
A behind-the-ear, BTE, aid keeps the main electronics behind the ear. Sound travels through tubing to a dome or custom earmould. BTE devices range from slim open-fit models to larger, more powerful instruments.
The NHS describes BTE aids as suitable for most people and among the easiest styles to use. Their larger case can provide more room for controls and power. A custom earmould can also provide secure retention and controlled sound delivery where more amplification is needed.
BTE aids may be worth considering when:
- Ease of handling is more important than minimum size.
- A stronger output or secure earmould is needed.
- Smaller controls or battery doors would be difficult.
- A robust, serviceable design is preferred.
Glasses do not automatically rule out a behind-the-ear style. The frame, aid and ear shape need to be considered together.
In-the-ear and in-the-canal hearing aids
In-the-ear, ITE, hearing aids place the electronics in a custom shell that occupies part of the outer ear. In-the-canal, ITC, versions are smaller and sit closer to the canal opening. Completely-in-canal, CIC, and invisible-in-canal, IIC, devices sit deeper.
Larger ITE devices can be easier to grip than very small aids and may offer more room for controls. Smaller canal aids are less visible, but their size can restrict battery capacity, wireless features, microphones or manual controls. They can also be harder to insert and remove.
Suitability depends on:
- The degree and shape of hearing loss.
- Ear-canal size and shape.
- Wax and moisture.
- Finger dexterity and eyesight.
- Whether rechargeable power, directional microphones or direct streaming are required.
Invisible should never be treated as a clinical advantage by itself. The smallest style is only useful if it can provide the required sound, stays comfortable and can be managed reliably.
What are CROS and BiCROS hearing aids?
CROS and BiCROS systems are considered when hearing is much poorer in one ear. A device on the poorer side picks up sound and routes it to the better side. BiCROS also amplifies sound for hearing loss in the better ear.
This can improve awareness of speech arriving from the poorer side, but it does not recreate normal binaural hearing. Sound localisation can remain difficult. Marked asymmetry also needs appropriate assessment and, where indicated, medical referral. NICE lists unilateral or asymmetric hearing loss among the signs that may require specialist investigation.
Does a smaller hearing aid work less well?
Not necessarily. Modern small aids can be capable devices, but physical space still creates trade-offs. Smaller shells may have less room for power, controls, directional microphone separation or wireless components. Some prescriptions also need a more closed earpiece or more powerful receiver, regardless of cosmetic preference.
The right comparison is not large versus small. It is whether each option can meet the prescription and daily listening goals while remaining comfortable and manageable.
How should the style be chosen?
NICE recommends discussing the audiogram, everyday communication needs, management options and the benefits and limitations of each option. A useful selection conversation should therefore cover:
- Your hearing results and whether one or two aids are appropriate.
- The conversations and environments you want to improve.
- Ear health, comfort and physical fit.
- Dexterity, eyesight and ability to manage the device.
- Rechargeable or replaceable batteries.
- Phone, television and assistive-device compatibility.
- Aftercare, adjustment and servicing.
- Total price and what is included.

Can Hear Better compare different styles?
Yes. Hear Better is independent and can compare suitable models from leading manufacturers after a free adult hearing assessment. Recommendations consider your prescription, daily life, comfort, handling, phone and budget. Assessment, fitting and lifetime aftercare are provided at home across the North East.
