LiNX 3D 9 Hearing Aids

The Resound Linx 3D 9 hearing aids are the latest top of the range, Made For iPhone hearing aid technology from GN Resound. They are truly outstanding devices as attested by Steve Claridge, (co-writer on Hearing Aid Know). They offer the pinnacle of Resound technology and will deliver outstanding results even in very complex sound situations. More than that though, we would expect them to deliver a completely new experience in hearing care to you if you want it.

Are The LiNX 3D 9s Any Good?

I would have to say they are exceptional, Steve has been wearing a pair for a while now and he is exceptionally happy with them. His reports can be seen on our blog, read them and allow a user explain clearly what they deliver. 

Vibrant and crystal clear sound

ReSound LiNX 3D hearing aids come with the superior sound quality of Surround Sound by ReSound. They work together, continuously exchanging data about your sound environment for optimized performance.

Linx 3D 9 Prices

We would expect the range to be sold at prices from £1700.00 to £2200.00 in the UK depending on the Practice and location. We would expect the range to be sold at prices from €2400.00 to €3000.00 in Ireland. We would expect the range to be sold at prices from $2400.00 to $3200.00 in the USA. Just to be clear, we don't set prices here and they differ from Practice to Practice across the World so our expectations aren't binding, they are just a guess and some research. Always remember, we all like to shop around, but always be clear about what is being delivered. You will need care and support, make sure you will get it. You will also need your hearing aid validated or verified to get the best experience, paying a little more to ensure your experience is good, is not wasted money. That's our price rant for the day over, let's talk about the devices.

• It is up to 50% better at identifying speech across various environments
• It enables users to hear up to 80% more of the sounds around them, and
• It enables users to understand up to 40% more speech in noise

So those are pretty interesting stats, but what is driving them, what's different and how does it deliver? Let's take a look at the underlying tech.

Binaural Directionality III

This is Resound's latest directionality strategy and is a further upgrade to what they have been doing. It involves continuous information exchange between the hearing aids which allows the optimal directionality in the hearing aids for the situation you are in.

What That Means

It simply allows you to focus on the sounds that are important to you, however, it also allows you to be aware of your surroundings. Some thing that is important so that your natural ability to hear in noise is activated.

Spatial Sense

This combines and preserves natural cues so that the brain has the optimal information for localisation of sound and spatial awareness.

What That Means

Put simply, your ability to localise sounds is hugely important, because it is one of the major elements in your ability to listen to the sound you want while ignoring the sound you don't. These devices deliver amazing spatial awareness. 

Binaural Environmental Optimizer II

This feature allows the hearing aid s to work together to analyse the listening environment you are in. It then automatically adjusts the features and amplification to deliver the best experience for you. 

What That Means

Knowing what the sound situation around you accurately is really important, so this feature identifies the situation with high accuracy and then manages the feature set of the hearing aids to deliver the very best hearing for you. This feature and its accuracy is imperative for the function of the aids. Resound are quoting really high accuracy and our experience concurs. 

Noise Tracker II

This is a unique noise reduction system that works on the basis of spectral subtraction. It reduces unwanted noise without affecting the speech signal. 

What That Means

The really important bit here is that it seems to do what they are saying. It is excellent on any noise that is steady state (which means recurring similarlily) like engine noise, background hum of any kind. Steve has seen some excellent benefits in noisy situations in particular in his car. 

DFS Ultra II With Music Mode

A high precision feedback system that allows the cancellation of feedback with extreme accuracy. The Music mode is a slower acting system which allows better handling of music.

What That Means

Feedback is probably one of the most annoying things for users. The feedback system allows the amplification that you need without causing that damned irritating whistling. Having a system which also has a music mode means that your appreciation of music will be better. Sometimes music can sound like feedback, a music mode allows the system a little more time to make sure it isn't and do nothing. That means less distortion for you. 

Resound Assist

Resound Assist is the really big news for both Providers and Users. Resound Assist will allow your provider to adjust your hearing aids remotely. That means if you want adjustments on the go, they can be provided without you having to attend the clinic. The system is really easy to use and is quite intuitive. This might not be for everyone, but this feature will be a god send for the people who love it. It will allow them complete freedom over their experience, over their customer experience.

The App, Resound Smart 3D

The accompanying app also allows you personalise your hearing experience in a deeper way. It has been re-designed to be more intuitive and easier to use and it offers real control. Again, this might not be for everyone, but for those who want it, it will enrich their experience. Again, this has to be seen as an excellent thing.

Linx 3D 9 Feature Set

The overall feature set of the 9 technology levels is as follows, each hearing aid may not have the full range of features here

Resound LiNX 3D 9 MIH-S (Microphone In Helix hearing aid)

Price

From £1700.00 to £2200.00 in the UK. From €2400.00 to €3000.00 in Ireland. From $2400.00 to $3200.00 in the USA.

The LTMIH-S is the smallest of the microphone in helix custom hearing aids. Because it is so small you will lose some of the benefits of the technology. However, that is always the trade off for discretion. The device is available with four levels of receiver power, LP, MP, HP and UP which means it can cover a lot of hearing loss, in fact from mild all the way to severe to profound. Again, the size of receiver available is based on the size of your ear canal. If your canal is too small, you won't be able to avail of the higher power receivers.

The functional features of this model are as follows, it can have a push button, volume control, the devices all have smart start which gives you a couple of seconds to get it in your ear before it comes on. But you lose out on the direct audio streaming, no ear to ear communication, and no wireless accessories. The aid takes a size 10 battery. 

By choosing discretion you do lose out on a lot of features and benefit. Firstly, there is no telecoil, something that many like. You also miss out on the new Resound smart 3D app and the remote assistance. You lose all the directionality functions because you only have one mic, no Wind Guard and you lose all the wireless functions. That is a lot of benefit gone, because you wanted it small, really think about this, because honestly, no one cares that you are wearing a hearing aid.

Feature Set

The feature set of the device is the same across receiver sizes and is as follows.

• Up to 17 channels of compression depending on tech level
• Environmental Classifier
• Environmental Optimizer II
• Noise Tracker II

• Low Frequency Boost (only with the HP Receiver)
• DFS Ultra III with Music Mode
• Auto DFS

The LTMIH is the larger of the microphone in helix custom hearing aids. Like it's smaller brother the LTMIH-S, because it is so small you will lose some of the benefits of the technology.

More importantly, you will get access to the Smart 3D app and all the benefits that it delivers to your experience. There is a telecoil on-board, however it is only available with the MP HP and UP receiver versions. You will still lose all the directional benefits though as they only come with one mic. The battery size on these models can be 312 or size 13.

The suitability for this device is also based on the size of your ear canal. If your canal is too small, you won't be able to avail of it.
