When using or considering purchasing a Phonak hearing aid, you quickly encounter a maze of terms and choices. Speakers in different strengths, lengths and systems: how do you know which one you need? And can you just switch between different types? In this blog – written from the practical experience of an audiologist – we explain everything step by step. From the latest Sound Delivery System 6.0 to the differences between S, M, P and MAV receivers. So you’ll know exactly what to look out for.
What does a speaker in a hearing aid actually do?
In a receiver-in-ear (RIE) hearing aid, the speaker is not in the device itself, but in the ear canal. The device behind the ear processes the sound, and the speaker in the ear canal ensures that the amplified sound is actually heard. So this speaker is essential for both sound quality and comfort.
Phonak offers several types of speakers for this purpose, tailored to hearing loss, fit and acoustic requirements. The speaker sits at the end of a thin wire that snaps into the hearing aid – and that wire looks like the cord running past your ear.
New: Sound Delivery System 6.0 – Infinio
Phonak’s latest generation of speakers is called Sound Delivery System 6.0. These Infinio speakers are a further development on previous generations, and are available in strengths:
- S (Standard)
- M (Medium)
- P (Power)
- MAV (ActiveVent Speaker)
S is intended for mild hearing loss and offers a fine, compact fit with less power. M is the most commonly used type, suitable for moderate hearing loss. P is designed for those who need more power, for more severe hearing loss.
MAV – what is that?
The MAV speaker is a so-called ActiveVent speaker. It contains an advanced mechanism that automatically adjusts the vent depending on the listening situation. For example: in music or noise, the vent automatically closes for richer sound; in quiet environments, it opens for more comfort and naturalness. Ideal for those who switch between situations a lot or for those who want to combine both amplification and open wearing comfort.
Note that the ActiveVent is only suitable for specific devices and requires close tuning in the software.
Important: software modification is necessary
A common misconception is that you can switch speakers yourself – for example, from an M to a P because you feel something is missing in the sound. But unfortunately, that’s not how it works. Each speaker requires a specific adjustment in the hearing aid software.
Without this adjustment (which can only be done by a hearing care professional), the device will not function properly. You may get a distorted sound image, feedback problems or even damage to the device. So never exchange speakers on your own.
Right or left, and what length?
Phonak speakers are available for the left or right ear and come in length sizes:
- 00 – extra short (quite rare)
- 0
- 1
- 2
- 3 – extra long
Shorter seems nicer – the cord will be tighter along the ear – but beware: a speaker that is too short may pull on the ear or ear canal. This can lead to pain, irritation or misalignment in the ear. A proper length prevents these problems. The length is always subtly marked on the speaker (e.g. R2 = right ear, length 2).
Sound Delivery System 5.0
The previous system – Sound Delivery System 5.0 – is still in full use and compatible with instruments from the Phonak Marvel, Paradise and Lumity lines. Again, you have a choice of S, M, P and MAV. Operation is largely similar to System 6.0, although the speakers are designed slightly differently and compatibility is limited to earlier devices.
Do you use a hearing aid from one of these series? Then chances are your speaker type is from SDS 5.0.
Fit speakers – what are they?
A separate category within Phonak speakers are the Fit Speakers, also called sensor speakers. These contain a sensor that collects information about the wearing environment, such as movement, moisture or body temperature. This data is used by the hearing aid to adjust automatically.
Special domes fit these speakers: the Vented Dome Clear 5.0, available in sizes S, M and L. These domes provide a comfortable fit with light ventilation, contributing to both wearing comfort and acoustic performance.
What happened to Sound Delivery System 4.0?
System 4.0 is no longer made by Phonak (some lengths and strengths are still in stock). The reason? The filter system(CeruDisc) was quite pricey and difficult to replace. Meanwhile, all newer speakers feature the widely used CeruStop filter, which is easily interchangeable and more widely available.
Practical tips from the audiologist:
- Use only original Phonak speakers and domes.
- Check the length of your speaker in case of irritation or disconnection.
- Clean the end of the speaker daily and check the filter.
Conclusion
With its loudspeaker systems, Phonak offers a wide range of solutions for different hearing needs. Whether you are looking for standard sound, more power or smart technology with active ventilation or sensors – there is always a suitable speaker, if correctly chosen and adjusted.
It can sometimes seem complicated, but with the proper explanation and guidance from your hearing care professional, you can take full advantage of what your hearing aid and speaker have to offer. Do you have questions about your current speaker, are you unsure about the length or want to switch to a new type? Please feel free to contact your hearing care professional – we are happy to help.
A well-tuned speaker makes the difference between just hearing and comfortable, clear listening. And that’s what we do it for.
